Chapter 3: Housing Constraints, Resources, and Fair Housing 3-81 California Tax Credit Allocation Committee (TCAC) Opportunity Area Maps The Department of Housing and Community Develo pment together with the California Tax Credit Allocation Committee established the California Fair Housing Task Force to provide research, evidence- based policy recommendations, and other strategic recommendations to HCD and other related state agencies/departments to further the fair housing goals (as defined by HCD). The Task force developed the TCAC/HCD Opportunity Area Maps to understand how public and private resources are spatially distributed. The Task force defines opportunities as pathways to better lives, including health, education, and employment. Overall, opportunity maps are intended to display which areas, according to research, offer low-income children and adults the best chance at economic advancement, high educational attainment, and good physical and mental health.

According to the Task Force’s methodology, the tool allocates the 20 percent of the tracts in each region with the highest relative index scores to the “Highest Resource” designation and the next 20 percent to the “High Resource” designation. Each region then ends up with 40 percent of its total tracts as “Highest” or “High” resource. These two categories are intended to help State decision-makers identify tracts within each region that the research suggests low-income families are most likely to thrive, and where they typically do not have the option to live—but might, if given the choice. As shown in Figure 3-11a below, much of Costa Mesa is classified moderate to high resource areas with pockets of low resource areas in the southwest region of the City. Costa Mesa has one area identified in Figure 3-11b classified as high segregation and poverty in the sout hern area of the City – census tract 636.05. This census tract includes industrial, residential, and retail/commercial uses, as well as the Costa Mesa Senior Center and new Superior Pointe and 17 West residential developments. While the area is identified as high segregation and poverty, it has seen much redevelopment over recent years and the median home value according to 2020 ACS 5-Year Estimates is $922,500. The median contract rent for the census tract is $1,665, and the median household income is $71,150.

These census tracts sit within part of the westside Costa Mesa community bound roughly by 19 th Street
to the north, Anaheim Avenue and Newport Blvd (55 Freeway) to the east, Industrial Way and 16th Street to the south, and Placentia Avenue to the north. The following is a qualitative analysis of the area based on observation and historical reference:
 The northern portion between 18th and 19th Streets is primarily single and lower density multi- family residential with some neighborhood serving commercial (including two grocery stores in Smart & Final and El Metate Market) along 19 th Street. Roadways ar e clean and sidewalk improvements were made approximately two years ago along Center Street and Pomona Avenue with a new slurry seal applied to most streets in the neighborhood around the same time.  Directly adjacent to this area across Anaheim Avenue is the renovated Downtown Recreation Center and new Norma Hertzog Community Ce nter, Costa Mesa (Donald Dungan Branch) Library, and Lions Park playground and ball fields. The City invested approximately $36.5 million into renovation of the area which serves as a vi tal resource to the surrounding neighborhoods.

The library and parks host community events and the Downtown Recreation Center host youth and adult sports leagues and daycare services for families. This area is also approximately a quarter mile from one of the City’s main commercial hubs in the Triangle Square shopping Center and Costa Mesa Courtyards shopping centers.
353

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-82  This area contains the Shalimar Drive neighbo rhood which has been found to require greater attention from code enforcement due to housing conditions. This analysis is described in Section 2.F.4 (Housing Age and Condition). Within that section, the City describes investment into the area through Community Clean-Up Da ys, staff time, and donations to community businesses and non-profit community groups multiple times per year.  South of 17 th Street is a mixture of light industrial/office and new townhome communities developed within the last four years. Portions of the street frontage and public ROW improvements along 17
th Street, Pomona Avenue, and Superi or Avenue have all been newly constructed as part of these new communities.
 Most all streets contain dedicated sidewalks with limited crac king or damage. Some industrial local roadways such as Commercial Way see roadwa y conditions typical throughout the City in light industrial areas, such as the areas furt her west between Placentia and Monrovia, along Harbor Blvd, and in the northeast portion of the City adjacent to the airport. These are maintained regularly through the City’s CIP.
 Placentia Avenue, which serves as the western boundary of the area, is a major thoroughfare through the City and has consistent sidewalk a nd on-street dedicated bike lanes which provide safe transit routes to Estancia High School directly to the north.  There are no school facilities within these census tracts but they are served by local schools in adjacent neighborhoods accessed by local neighborhood roads. School buses have regular pick ups at the Costa Mesa Women’s Club parking lot and at several stops in the area to transport K- 5 students to local public schools.
 All major roadways in this area (16th, 17th, 18th, 19th Streets and Pomona, Placentia, and Anaheim Avenues) are maintained consistent with the rest of the City and none show a current need for major repair.
 The Orange County Transportation Authority (OCTA) runs multiple bus lines (47, 55, 178) along 17th Street, 19th Street, and Placentia Avenue regularly with approximately 15 minute headways for most routes during weekdays.

As demonstrated above, these areas have recently received a large amount of City investment through the Downtown Recreation Center, Library, and Lions Park projects. These projects added vital community amenities and improved corresponding streets and public ROW areas. These census tracts, while designated as an Area of High Segregation and Poverty, see community investment consistent with or in excess of the typical condition citywide. Program 2L is included in the Housing Plan to facilitate access to funding, priority processing, and outrea ch for lower income households, including those located in census tract 636.05. Program 4I is also included to specifically address the high segregation and poverty finding for census tract 636.05 by part nering with local community-based organizations, stakeholders and groups who provide supportive reso urces and programs to further identify specific needs of this community and connect community members with appropriate resources.

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-85 Opportunity Areas – Education
The TCAC/HCD Opportunity Area Maps include education data, as illustrated in Figure 3-12 . This data represents opportunity levels based on the following four factors:
 Math proficiency – Percentage of 4th graders who meet or exceed math proficiency standards.  Reading proficiency – Percentage of 4th graders who meet or exceed literacy standards.  High school graduation rates – Percentage of high school cohort that graduated on time.  Student poverty rate – Percentage of students not receiving free or reduced-price lunch.

As Figure 3-12 shows, the City has a variety of education outcome scores. The more positive education outcomes are located over East Side Costa Mesa, east of the 55 Freeway, as well as over the neighborhoods south of the 405-freeway and in the ce nter of the City. The area of the City west of Harbor Boulevard and north of Fairview Park are rated mo derate for educational outcomes. West Side Costa Mesa in the City’s south-western region has the lowest educational outcome.

Title 1 schools receive additional government funding to assist their lower-income student base who are at risk of falling behind. Within Newport-Mesa Unified School District, there are a total of 10 elementary schools, 2 middle schools, and 2 high schools. The following 3 elementary schools are Title 1 schools: Davis Elementary School, Heinz Kaiser Elementary School, and Woodland Elementary School. Davis Elementary S c h o o l i s l o c a t e d i n t h e c e n t e r o f C o s t a M e s a j u s t north of the OC Fairgrounds and Heinz Kaiser and Woodland Elementary Schools are both located in East Side Costa Mesa between the 55 Freeway and the Upper Newport Bay State Marine Conservation Area.

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-87 Opportunity Indicators
Opportunity indicators also help inform communiti es about disparities in access to opportunity. The Department of Housing and Urban Development (HUD) developed the opportunity indicators to help inform communities about disparities in access to opportunity, the scores are based on nationally available data sources and assess resident’s access to key opportunity assets in the City. Table 3-20 provides the index scores (ranging from zero to 100) for the following opportunity indicator indices:
 Low Poverty Index: The low poverty index captures poverty in a given neighborhood. The poverty rate is determined at the census tract level. The higher the score, the less exposure to poverty in a neighborhood.
 School Proficiency Index: The school proficiency index uses school-level data on the performance of 4th grade students on state exams to describe which neighborhoods have high-performing elementary schools nearby and which are near lower performing elementary schools. The higher the score, the higher the school system quality is in a neighborhood.  Labor Market Engagement Index: The labor market engagement index provides a summary description of the relative intensity of labor market engagement and human capital in a neighborhood. This is based upon the level of employment, labor force participation, and educational attainment in a census tract. The higher the score, the higher the labor force participation and human capital in a neighborhood.
 Transit Trips Index: This index is based on estimates of transit trips taken by a family that meets the following description: a three-person single-parent family with income at 50% of the median income for renters for the region (i.e. the Core-Based Statistical Area (CBSA)). The higher the transit trips index, the more likely residents in that neighborhood utilize public transit.  Low Transportation Cost Index: This index is based on estimates of transportation costs for a family that meets the following description: a three-person single-parent family with income at 50 percent of the median income for renters for the region/CBSA. The higher the index, the lower the cost of transportation in that neighborhood.
 Jobs Proximity Index: The jobs proximity index quantifies th e accessibility of a given residential neighborhood as a function of its distance to all job locations within a region/CBSA, with larger employment centers weighted more heavily. The higher the index value, the better the access to employment opportunities for residents in a neighborhood.  Environmental Health Index: The environmental health index summarizes potential exposure to harmful toxins at a neighborhood level. The higher the index value, the less exposure to toxins harmful to human health. Therefore, the higher the value, the better the environmental quality of a neighborhood, where a neighborhood is a census block-group.

Table 3-20 below displays the opportunity indices by race and ethnicity for persons in Costa Mesa.

According to the data, there is some poverty among the population of Costa Mesa, across all racial/ethnic groups. There are higher levels of poverty among the Hispanic and Native American populations. All racial/ethnic groups in Costa Mesa experience levels of environmental health below 50, meaning all residents are exposed to a higher degree of environmental pollutants. Otherwise, the data shows the City has high marks for school proficiency, labor market, transit, transportation cost, and job proximity. 359

Access to Transit
Transit explores metrics that reveal the social and ec onomic impact of transit, specifically looking at connectivity, access to jobs, and frequency of service. According to the data provided and as shown in Figure 3-13, Costa Mesa scored a 5.4 AllTransit performance score, illustrating a moderate combination of trips per week and number of jobs accessible that enable a moderate number of people to take transit to work. In comparison to neighboring ci ties – Huntington Beach scores a 4. 4, Irvine scored a 3.6, Santa Ana scored a 6.6, and Newport Beach scored a 3.9. Access to transportation increases both the economic and environmental/health opportunities. Additionally, AllTransit provides the following data for Costa Mesa transportation:
 98.8% of jobs are located within ½ of transit.
 99,721 customer households have access to a business within a 30-minute transit commute.  2.29% of workers walk to work and 1.43% bike to work
 There are no households within a ½ miles of high frequency transit.  On average, there are 6 transit routes within ½ of a block group on average. 360

Environmental Justice
The California Office of Environmental Health Hazard Assessment (OEHHA ) developed a screening methodology to help identify California communities disproportionately burdened by multiple sources of pollution called the California Communities Environmen tal Health Screening Tool (CalEnviro Screen). In addition to environmental factors (pollutant exposure, groundwater th reats, toxic sites, and hazardous materials exposure) and sensitive receptors (seniors, children, persons with asthma, and low birth weight infants), CalEnviro Screen also takes into consideration socioeconomic factors. These factors include educational attainment, linguistic isolation, poverty, and unemployment. Research has shown a heightened vulnerability of people of color and lower socioeconomic status to environmental pollutants. Figure 3-14 below displays mapped results for the CalEnviro Screen in Costa Mesa and the Orange County region. The map shows that Costa Mesa is prim arily moderate-scoring, with a few low-scoring census tracts and a couple high-scoring census tracts. High scores signify high levels of pollution burdens and low scores signify 361

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-90 low levels of pollution. Table 3-22 and Table 3-23 below identifies the CalEnviro Screen scores for the highest and lowest scoring census tracts in Costa Mesa, respectively.

3. Discussion of Disproportionate Housing Needs
The analysis of disproportionate ho using needs within Costa Mesa eval uates existing housing need, need of the future housing population, and units within the community at-risk of converting to market-rate.

Existing Needs
As described in Section 3.G.1 of this Housing Element, the Orange County Housing Authority (OCHA) administers Section 8 Housing Choice vouchers within the Ci ty of Costa Mesa. Fo r the 2020 year, there were a total of 561 Section 8 voucher holders within the community: 110 for persons with disabilities, 394 for seniors, and 54 families with at least one dependent.

Housing Needs in Costa Mesa
A variety of factors affect housin g needs for different households. Mo st commonly, disability, household income, and household characteristics shape the type and size of housing needed, as well as accessibility based on existing units in a City. Tables 3-24 through 3-31 display data for demographic characteristics of Costa Mesa, as compared to Orange County and the State of California. Additional detailed analysis of the Costa Mesa community is provided in Chapter 2: Community Profile.

Table 3-24 displays the data for persons with disabilities in the City, County, and State. Overall, about 10.6 percent of the California population has at least one disability. Orange County and the City of Costa Mesa both have lower percentages by about 2 percent less persons with disabilities. Ambulatory, Independent Living, and Cognitive Difficulties are the top three most common disabilities for all three jurisdictions, in order starting from most common. These figures may be reflective of disabilities commonly found amongst the senior population. Each of reasonable accomm odation procedures and o pportunity for accessible housing can provide increased housing security for the population with disabilities.

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-94 Table 3-25 and Table 3-26 displays household type and income data for the State, County, and City. Overall, Orange County has the largest percentage of family households (71.7 percent) and Costa Mesa has the smallest with about 10 percent less. Costa Mesa has the lowest percentage of female households without a spouse. Non-family households represent the larges t household type in Costa Mesa at 40.5 percent, which is about 9 percent more than California and 12 percent more than Orange County. About 40 percent households in both the State and the County have at least one person above the age of 60, while there are about 30 percent of households in Costa Mesa with at least one person over the age of 60. Different household types have varying housing needs – se nior households may benefit from reasonable accommodation procedures and being located near medical facilities, single-parent households may benefit from affordable housing options due to limi ted income, and family households may benefit from larger housing units located near community areas and schools.

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-95 Figure 3-16 below shows the City has varying rates of married-couple households throughout its different census tracts. In general, the map shows the eastern and western edges of the City, which are predominantly single-family neighborhoods, have the highest rates of married-couple households (40-60 percent). Towards the center of the City, census tr acts report approximately 20 to 40 percent married- couple households.

When compared to Figure 3-17 , the census tracts with the highest rates of married-couple households overlap with the highest rates of children living in married-couple family households. Costa Mesa has a generally high propensity of children living in marri ed-couple family households throughout most census tracts. In comparison to neighboring communities, however, Costa Mesa has less census tracts with children in married-couple family households.

Figure 3-18 shows the City, as with its neighboring communities, has very low rates of children living in female- headed households with no spouse present. Most of the City reports approximately 20 percent of less, except for a census tract towards the southern edge of the City which reports 40 to 60 percent of children living in female-headed households. This same census tract is also one of two which reports 20 to 40 percent of its population over the age of 18 living alone, as illustrated in Figure 3-19. The rest of the City has fairly low rates of individuals living alone, with the remaining census tracts reporting less than 20 percent.

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-100 Table 3-27 displays data for households experiencing overpayment or cost burden in the State, County, and City. Housing cost burden can cause mainly displace ment, which may create limited access to essential goods and community, as well as employment by pote ntially increasing commute times. The percentages of households that experience a cost burden greater than 30 percent is overall similar amongst the State, County, and City. Costa Mesa experiences higher ra tes of cost burden than the County by about two percent. The City also has the largest percentage of households with a cost burden over 50 percent at about

21.6 percent, compared to about 19 percent in both the State and County. Increased opportunity for affordable housing and housing assistance funds help to prevent cost burden on households.

Figure 3-20 shows household overpayment for homeowners and Figure 3-21 shows household overpayment for renters. As illustrated, overpayment disproportionately affects Costa Mesa renters compared to homeowners. Overpayment for homeowners is greater in census tracts along the 55 Freeway.

Overpayment for renters is higher to the south of the City in census tracts along Placentia Avenue and to the north in Mesa Verde and along Harbor Boulevard.

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-103 Table 3-28 displays data for household tenure (homeowners and renters) for the State, County, and City.

Homeownership is a crucial foundation for households with low incomes to build strength, stability, and independence. The opportunity for transition into the homebuyer’s market is important in a healthy housing market. Table 3-28 shows that the City of Costa Mesa has a much lower percentage of homeowners than the County and State, reporting about 38 percen t, compared to 57 percent in the County and 55 percent in the State. Costa Mesa also has higher rates of renter at 62 percent, compares to 43 percent in the County and 45 percent in the State.

Additionally, Table 3-29 displays data for overcrowding. Overcrow ding is defined as between 1.01 and 1.5 persons per bedroom in a household, and severe overcr owding is defined as more than 1.51 persons per bedroom. Overcrowding often occurs when nonfamily members combine incomes to live in one household, such as college students and roommates. Overcrowding also occurs when there are not enough size- appropriate housing options for large or multigenerational households. The City has the lowest percentages of owner-occupied households with overcrowded and severely overcrowded households compared to the County and State. Renters in Costa Mesa are disproportionately affected by overcrowding when compare to homeowners. Overall, across all three regions, owners were less affected by overcrowding and severe overcrowding.

Figure 3-22 also shows overcrowded households within the City. The figure shows three census tracts with over 20 percent of overcrowded households along Placentia Avenue west of the 55 Freeway. This also overlaps with areas of high overpayment rates for renters, higher levels of pollution burdens, low TCAC resource areas, as well as the High Segregation and Poverty area. As noted throughout this AFFH analysis, the City has placed a great amount of attention on the area. New residential developments and a new library, community center, and senior center in the area have participated in improving access to resources and general revitalization of the area. A number of candi date housing sites are located within this higher overcrowding region, and the City will work further with developers in ensuring that amenities, sidewalks, streetscape, and general conditions meet the needs of the community.

Table 3-30 and 3-31 display comparative housing stock data fo r the State, County, and City. Table 3-20 below shows data for occupied housing units by ty pe. A variety of housing stock provides increased opportunity in communities for different size and hous ehold types. The majority of housing stock in Costa Mesa is multi-unit developments (50.6 percent for 2 or more units). Single-family housing units represent about 48 percent of the housing stock in Costa Mesa. Comparatively, single family units represent about 63 percent and 64 percent of the housing stock in the County and the State, respectively.

Table 3-31 below displays housing stock by year built for the City, County, and State. Older housing units generally require more upkeep, regular maintenance, and can cause a cost burden on both renters and homeowners. The majority of Costa Mesa’s housing stock (68.2 percent) was built during a housing boom between 1950 and 1979. The trend is similar for the County and State, with majority of units built between 1980 and 2013. Overall, increased numbers of older hous ing can lead to displace ment, cost burden, and substandard living conditions. An analysis of the housing stock in provided in Chapter 2: Costa Mesa Community Profile.

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-106 Future Growth Need
The City’s future growth need is based on the RHNA production of 2,919 very low and 1,794 low-income units within the 2021-2029 planning period. Appendix B of this Housing Elements shows the City’s ability to meet its 2021-2029 RHNA need at all income levels. This demonstrates the City’s ability to accommodate the anticipated future affordable housing needs of the community.

4. Displacement Risk
The potential for economic displacement risk can result from a variety of factors, including large-scale development activity, neighborhood re investment, infrastructure investments, and changes in local and regional employment opportunity. Economic displacement can be an inadvertent result of public and private investment, where individuals and families may not be able to keep pace with increased property values and market rental rates.

Urban Displacement
The Urban Displacement Project developed a neig hborhood change database to map neighborhood transformations and identify areas vulnerable to gentrification and displacement. This data was developed to assist local decision makers and stakeholders better plan for existing communities and provide additional resources to areas in need or at-risk of displacement and gentrification. Table 3-32 provides the criteria used to identify each displacement typology and the total number of Costa Mesa Census Tracts that currently fall within each category.

Table 3-32 and Figure 3-23 both show the City is mostly made up of census tracts which are currently identified as “exclusive” or are in the process/at-risk of becoming exclusive. These areas overlap with most of the City’s single-family neighborhoods. Two census tracts on the west-side of Costa Mesa and to the east of Placentia Avenue are currently identified as lo w-income and susceptible to displacement. The south- western-most census tract to the west of Placentia Avenue is categorized as “Advanced Gentrification”, signifying a rapid increase in housing cost over the past few years. A possible reason for these classifications may be new developments within the census tract and the recently added/renovated public library, community center, and senior center. The census tracts have also seen increases in housing cost; however, this is fairly consistent with the City as a whole and the region. As detailed in the section above, the area has historically been subject to lower access to resources, higher poverty and segregation rates, and greater pollution burdens. These recent projects and invest ments in the community seek to improve conditions and amenities for residents. Candidate sites have also be en identified in this area, as detailed in Appendix B, which may provide for future affordable housing units to increase housing choices and opportunities and amenities for existing residents. The City has work ed with developers constructing new residential developments in the area and will continue to ensure that future projects consider the needs of the existing community. The Housing Plan contains a number of programs to facilitate these partnerships with both the community and housing developers, as well as limit displacement and the gentrification of the area. 379

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-109 Inventory of Assisted Affordable Housing
Affordable covenants help to ensure that certain housing units remain affordable for an extended period of time. Covenants provide lasting affordable opti ons to low and very low-income households in a community. Table 3-33 below provides a list of 1,144 housing units with affordability covenants, of which 75 housing units are at-risk of converting to market-rate between 2021 and 2031.

Jurisdictions are required by State Housing Element Law to analyze government -assisted housing that is eligible to convert from lower income to market rate housing over the next 10 years. State law identifies housing assistance as a rental subsidy, mortgage su bsidy or mortgage insuranc e to an assisted housing development. Government assisted housing may convert to market rate housing for several reasons, including expiring subsidies, mortgage repayments, or expiration of affordability restrictions. Consistent with the requirements to analyze the impacts of the potential conversion of these units to market-rate units, this section provides an analysis of preservation of assisted housing units at-risk of conversion.

Cost of Preservation of Units
While there are many options to preserving units including providing financial incentives to project owners to extend lower income use restrictions, purchasing a ffordable housing units by a non-profit or public agency, or providing local subsidies to offset the difference between the affordable and market rate units, the strategy considered below is to provide local rental subsidy to residents. The rent subsidy would provide financial assistance to residents if their affordable units converted to market rate. To determine the subsidy needed, Fair Market Rents were compared to market rate rents.

Cost of Replacement of Units
The City of Costa Mesa can also consider the cost of replacing the units with new construction. Construction cost estimates include all hard and soft costs associated with construction in addition to per unit land costs.

The analysis assumes the replacement units are apartments with concrete block with steel frame buildings and parking provided on-site. Square footage estimates are based on estimated size of units to be replaced and assume housing units are developed on multi- family zoned properties. Land costs have been determined on a per unit basis.

Resources for Affordable Housing Units
A variety of programs exist to help cities acquire, replace, or subsidize at-risk affordable housing units. The following summarizes financial resources available:
 Community Development Block Grant (CDBG) – CDBG funds are awarded to cities on a formula basis for housing activities. The primary objective of the CDBG program is the development of viable communities through the provision of dece nt housing, a suitable living environment and economic opportunity for principally low- and moderate-income persons. Eligible activities include administration, fair housing, energy conservation and renewable energy sources, assistance for economic development, public facilities and improvements and public services.  HOME Investment Partnership – Local jurisdictions can receive funds by formula from the Department of Housing and Urba n Development (HUD) to increase the supply of decent, safe, sanitary, and affordable housing to lower income households. Eligible activities include housing acquisition, rehabilitation, and development, homebuyer assistance, and rental assistance.  Section 8 Rental Assistance Program – The Section 8 Rental Assistance Program provides rental assistance payments to owners of private, market rate units on behalf of very low-income tenants, senior citizens, disabled and/or handicapped persons, and other individuals for securing affordable housing.
 Section 202/811 Program – Non-profit and consumer cooperat ives can receive no-interest capital advances from HUD under the Section 202 program for the construction of very low-income rental housing with the availability of supportive servic es for seniors and persons with disabilities. These funds can be used in conjunction with Section 811, which can be used to develop group homes, independent living facilities and immediate care facilities. The capital advance funding can also provide project rental assistance for the properti es developed using the funds. Eligible activities include acquisition, rehabilitation, new construction, and rental assistance.  California Housing Finance Agency (CalHFA) Multifamily Programs – CalHFA’s Multifamily Programs provide permanent financing for the acquisition , rehabilitation, and preservation of new construction of rental housing that includes affordable rents for low- and moderate-income 383

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-112 families and individuals. One of the programs is the Preservation Loan program which provides acquisition/rehabilitation and permanent loan fina ncing designed to preserve or increase the affordability status of existing multifamily housing projects.  Low-Income Housing Tax Credit (LIHTC) – This program provides tax credits to individuals and corporations that invest in low-income rental housing. Tax credits are sold to those with high tax liability and proceeds are used to create housing. Eligible activities include new construction, rehabilitation, and acquisition of properties.
 California Community Reinvestment Corporation (CCRC) – The California Community Reinvestment Corporation is a multifamily affordable housing lender whose mission is to increase the availability of affordable housing for low-in come families, seniors, and re sidents with special needs by facilitating private capital flow from its investors for debt and equity to developers of affordable housing. Eligible activities include new construction, rehabilitation, and acquisition of properties.

Qualified Entities for Preservation of Affordable Housing Units The following organizations may potentially assist in preserving future at-risk units:
 Jamboree Housing Corporation
 Irvine Housing Opportunities, Inc.
 Bridge Housing Corporation
 The Irvine Company
 Orange County Housing Authority
 Housing Corporation of America
 Southern California Housing
Development Corporation
 Century Housing
Quantified Objectives
Housing Element law requires that cities establish th e maximum number of units that can be preserved over the planning period. The City’s objective it to preserve the 75 affordable housing units “at-risk” of converting to market rate through policy programs provided in Chapter 4: Housing Plan.

SB 330
Effective January 1, 2020, Senate Bi ll 330 (SB 330) aims to increase resi dential unit development, protect existing housing inventory, and expedite permit processing. Under this legislation, municipal and county agencies are restricted in ordinances and polices th at can be applied to residential development. The revised definition of “Housing Development” now contains residential projects of two or more units, mixed- use projects (with two-thirds of the floor area designated for residential use), transitional, supportive, and emergency housing projects. SB330 sets a temporary 5- year prohibition of resi dential density reduction associated with a “housing development project”, from January 1, 2020, to January 1, 2025. For example, during this temporary prohibition, a residential triplex cannot be demolished and replaced with a duplex as this would be a net loss of one unit.

The City is committed to making diligent efforts to engage underrepresented and disadvantaged communities in studying displacement.

5. Summary of Fair Housing Analysis
The analysis conducted in this section regarding fa ir housing issues within Costa Mesa yielded the following conclusions:
 The dissimilarity analysis shows that nearly all racial and ethnic groups experience moderate to high segregation in the City of Costa Mesa. The Native Hawaiian and the Hispanic population experience the highest levels of segregation, meaning that to create a more integrated city, more than 45 percent of each respective population wo uld need to move into a predominantly white census tract.
 There are no racially or ethnically concentrated census tracts (RECAPs) within Costa Mesa as identified by HUD. This indicates that there are no census tracts within the City with a non-white population of 50 percent or more or any census tr acts that have a poverty rate that exceeds 40% or is three or more times the average tract poverty rate for the metropolitan area. However, there is one area identified as high segregation and poverty.  The data shows that Costa Mesa has ten block groups which meet the criteria for racially concentrated areas of affluence (RCAA). RCAAs are areas which the population is predominantly white with an income over $125,000 or higher.
 The UC Davis Regional Opportunity Index shows that the majority of residents within Costa Mesa have a moderate to high level of achievement and attainment. However, there are two census tracts in the south western portion of the City which show the lowest levels of attainment and achievement for residents, these areas also overlap with the high segregation and poverty area identified by the TCAC map (Figure 3-5b).
 The UC Davis Regional Opportunity Index (ROI)shows that the majority of residents within Costa Mesa have the highest level of access to opportunity throughout the City. Additional analysis of the ROI maps show that the northern portion of the City has moderate to lower levels of access to affordable or appropriate housing.
 The City provides moderate transit trip opportunity, a score of 5.4. Additionally, about 98.8% of all City jobs are within ½ mile of transit but just under 3 percent of the working population uses public transit as a primary source of transportation.
 The City has demonstrated the ability to meet th e anticipated future affordable housing needs of the community through the designation of sites to meet the very low and low income RHNA need (Appendix B: Candidate Si tes and Housing Resources ). These sites are dispersed throughout the community and are identified on sites with high opportunity for residential development.  There are 75 current units with affordable covenant s at risk of converting to market rate before the year 2029 in the City.
 The CalEnviro Screen mapping tool (2018) identified most of the Ci ty as “moderate” to “low to moderate” scoring, indicating moderate exposure to harmful pollutants. Additionally, the area which is identified as high segregation and poverty is the highest scoring census tract on the CalEnviro Screen map, indicating high exposure to harmful pollutants.

6. Assessment of Contributing factors to Fair Housing in Costa Mesa Regionally Identified Contributing Factors
As identified by the AI and the above analysis the City of Costa Mesa experiences the following local contributing factors to fair housing:
 Housing Discrimination – The 2020 AI identified housing discrimi nation as an impediment to fair housing choice in the City. The AI reports that 609 households in Costa Mesa received fair housing services relating to general housing issues and discrimination allegations. The Fair Housing Foundation (FHF) received 65 housing discrimination inquiries with 9 based on physical or mental disability, 8 related to race, 2 related to national origin, 2 related to gender, 1 related to sexual orientation, and 5 related to familial status.
o Through CDBG funding the City contracts with the Fair Housing Foundation to provide educational and support services to persons who experience housing discrimination in Costa Mesa. Services include: 1) responding to discrimination inquiries and complaints through screening and counseling, 2) document ing discrimination complaints by opening fair housing cases, 3) investigating discrimination complaints through extensive testing, and 4) resolving discrimination complaints through conciliation, mediation, administrative agency referrals, and litigation.
 Racial and Ethnic Segregation – The Analysis above identifies moderate segregation through the dissimilarity index analysis. Persons who identify as Hispanics, Asian, Native Hawaiian, American Indian, and Black experience over 30 percent dissimilari ty with the white population in Costa Mesa.

Additionally, while the R/ECAP analysis did not identify R/ECAPs in the City, there are two racially and ethnic concentrated areas of poverty near the City consisting of primarily Hispanic and Asian population. o During the AI report period, the City distributed literature on fair housing in English, Spanish, and Vietnamese to target neighborhoods and in conjunction with other neighborhood improvement efforts. This information was also provided at workshop events, at community centers, and at City Hall.
o The City will continue to outreach specifically to low and very low-income residents as wells considered targeted outreach to residents with moderate and high levels of segregation,  Unfair Lending – The Lending Analysis identifies lower rates of home loan approval for moderate, low, and very low-income residents. Additionally, applicants in Costa Mesa who identify as Black experience both lower rates of home loan approv al and purchase and higher rates of home loan denial, indicating disparity in access to funding.
o Currently, the City does not offer homebuyer assistance, but the AI reports that information on housing rehab programs are avai lable on the City’s website. The City will continue to provide important ownership information on the City’s website. Costa Mesa recognizes that an educated community is an empowered commitment and will considered target education and outreach about loan purchase to residents.  Overcrowding – the Analysis of Existing Housing Needs in Costa Mesa identified a significantly higher percentage of renters who experience overcrowding in the City than in the County and the State. Overcrowding can be an indicator of multi-generational living, however in renter ship it is 386

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-115 often an indicator that there are not sufficient affordable housing options causing residents to increase the number of persons per unit to lower the overall cost of housing. Overcrowding may also indicate a lack of adequate housing unit types available to residents with large families. While the City does not build housing, they will work wi th developers and interested parties to increase feasibility and opportunities for both affordable housing and multigenerational housing.

Locally Identified Contributing Factors
There are a number of factors and elements that contribute to and cause fair housing issues. The following lists a number of contributing factors within the City of Costa Mesa:
 Community Opposition – As a part of the Housing Element Update, the City hosted a variety of community engagement opportunities to gather feedback and input related housing needs. A large number of community members identified an ov erall objection to new housing in the City, specifically higher income housing. Traditionally, affordable housing and higher density residential projects receive community pushback or oppositi on. However, outreach and education can help to shift negative views of additional housing in a positive manner.  Lack of Investment in Specific Neighborhoods – The TCAC map identified census tract:
06059063605 as an area of high segregation and poverty (Figure 3-5b); meaning the demographics of this tract are consistent with the standards for both poverty (30% of the population below the federal poverty line) and racial segregation. Additi onally, this census tract is scored as lowest opportunity in civic life , health, mobility, housing, economy, and education by the UC Davis ROI:

People (Figure 3-8), which is a relative measure of people’s assets in a census tract. While the area was scored as low opportunity for resident assets, it was scored highest opportunity for Place (Figure 3-9), meaning the geographic area has high assets and opportunity in education, economic, housing, mobility, health and civic life. The census tract is also identified as having less positive educational outcomes by the TCAC-Education map ( Figure 3-12 ) and the highest exposure to harmful pollutants according to the CalEnviro Screen ( Figure 3-14 ). Combined data shows that conditions in this area may exacerbate existing segregation trends, low opportunity for community and resident enhancement and upward mobility a nd that there may be overall lack of public investment in the area.
 Displacement of Residents Due to Economic Pressures – The data in the RCAA analysis ( Figures 3- 6 through 3-7 ) show that there are ten census tracts which meet the criteria for a racially concentrated area of affluence (RCAA). The definition for an RCAA is a census tract in which 80 percent or more of the populat ion is White and has a median income of at least $125,000. The RCAAs are located in the highest resource and highest opportunity areas and are also within areas with the lowest exposure to harmful pollutants. If RCAA expand and gentrification occurs across the city, lower income households are at risk of displacement due to economic pressures and potential changing or increasing costs in housing and essential retail.

7. Analysis of Sites Pursuant to AB 686
387

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-116 AB 686 requires that jurisdictions id entify sites throughout the community in a manner that is consistent with its duty to affirmatively further fair housing. The site identification requirement involves not only an analysis of site capacity to accommodate the RHNA (provided in Appendix B ), but also whether the identified sites serve the purpose of replacing segregated living patterns with truly integrated and balanced living patterns, transforming racially and ethnically concentrated areas of poverty into areas of opportunity.

Figures 3-24 through 3-32 below identify the sites to accommodate future housing, as identified in the adequate sites analysis, overlaid on demographic data using the 2022 American Community Survey 5-Years Estimates.

A. Segregation and Integration
This section evaluates the proposed housing sites inventory in relation to segregation and integration indicators, including race/ethnicity and income.

Race and Ethnicity
Figures 3-24 and 3-25 show the proposed sites inventory in relation to predominant race or ethnicity of the area in which each site is located.
 120 housing element sites, or 71.9 percent of the sites, are located in areas where the predominant population is White alone, not Hispanic or Latino. These site s accommodate 10,811 units, or 87.0 percent of the total RHNA capacity analyzed. Of those units, 3,510 units are lower-income units, 1,920 units are moderate-income units, and 5,381 units are above moderate-income units.  47 housing element sites, or 28.1 percent of the sites, are located in areas where the predominant population is Hispanic or Latino. These sites accommodate 1,617 units, or 13.0 percent of the total RHNA capacity analyzed. Of those units, 564 units are lower-income units, 287 units are moderate- income units, and 766 units are above moderate-income units.

The data shows that the proposed sites inventory is not concentrated in areas with higher concentrations of non-White populations. A majority of both sites and total RHNA capacity are located in areas where the predominant population is White alone, not Hispanic or Latino. This includes 86.2 percent of the lower- income RHNA capacity, indicating that the lower-income capacity in the sites inventory is primarily located outside areas where the predominant population is Hispanic or Latino.

What does this mean? This distribution supports AFFH objectives by providing opportunities for future housing development, including lower-income housing, in areas that are not characterized by higher concentrations of communities of color. However, the inventory also includes a meaningful share of sites and units in predominantly Hispanic or Latino areas.

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-119

Income — Low- and Moderate-Income Population
Figure 3-26 shows the proposed sites inventory in relation to census data identifying the percentage of low- and moderate-income residents in the areas where the sites are located. Figure 3-26 shows the following findings:
 29 housing element sites, or 17.4 percent of the sites inventory, are located in areas where the low- and moderate-income population is less than 10 percent. These sites accommodate 1,146 units, or

9.2 percent of the total RHNA capacity analyzed. Of those units, 333 units are lower-income units, 218 units are moderate-income units, and 595 units are above moderate-income units.  83 housing element sites, or 49.7 percent of the sites inventory, are located in areas where the low- and moderate-income population is between 10 and 14.9 percent. These sites accommodate 9,397 units, or 75.6 percent of th e total RHNA capacity analyzed . Of those units, 3,069 units are lower-income units, 1,652 units are moderate-income units, and 4,676 units are above moderate- income units.
391

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-120  48 housing element sites, or 28.7 percent of the sites analyzed, are located in areas where the low- and moderate-income population is between 15 and 19.9 percent. These sites accommodate 1,687 units, or 13.6 percent of the total RHNA capacity analyzed. Of those units, 605 units are lower-income units, 301 units are moderate-income units, and 781 units are above moderate-income units.  7 housing element sites, or 4.2 percent of the sites inventory, are located in areas where the low- and moderate-income population is 20 percent or greater. These sites accommodate 198 units, or

1.6 percent of the total RHNA capacity analyzed. Of those units, 67 units are lower-income units, 36 units are moderate-income units, and 95 units are above moderate-income units.

The data shows that the majority of the sites inventory capacity is located in areas with relatively lower shares of low- and moderate-income residents. Approximately 85 percent of the total RHNA capacity is located in areas where the low- and moderate-income population is below 15 percent. Similarly, approximately 83.5 percent of the lower-income RHNA capacity is located in these same areas.

What does this mean? This distribution supports AFFH objectives because the sites inventory does not concentrate lower-income RHNA capacity in areas with higher concentrations of low- and moderate-income residents. Instead, the lower-income RHNA capacity is primarily located in areas with comparatively stronger income characteristics, which may help expand housing choice and access to economic opportunity. 392

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-121

Income — Median Household Income
Additionally, the City analyzed the proposed sites inventory in relation to median household income and noted the following key findings:
 10 housing element sites, or 6.0 percent of the sites analyzed, are located in areas with a median household income below $75,000. These sites accommodate 492 units, or 4.0 percent of the total RHNA capacity analyzed. Of those units, 148 units are lower-income units, 94 units are moderate- income units, and 250 units are above moderate-income units.  57 housing element sites, or 34.1 percent of the sites analyzed, are located in areas with a median household income between $75,000 and $99,999. Thes e sites accommodate 1,675 units, or 13.5 percent of the total RHNA capacity analyzed. Of those units, 517 units are lower-income units, 313 units are moderate-income units, and 845 units are above moderate-income units.  48 housing element sites, or 28.7 percent of the sites inventory, are located in areas with a median household income between $100,000 and $124,999. These sites accommodate 2,353 units, or 18.9 393

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-122 percent of the total RHNA capacity analyzed. Of those units, 792 units are lower-income units, 463 units are moderate-income units, and 1,098 units are above moderate-income units.  45 housing element sites, or 26.9 percent of the sites inventory, are located in areas with a median household income between $125,000 and $149,999. These sites accommodate 7,809 units, or 62.8 percent of the total RHNA capacity analyzed. Of those units, 2,578 units are lower-income units, 1,318 units are moderate-income units, and 3,913 units are above moderate-income units.  7 housing element sites, or 4.2 percent of the sites analyzed, are located in areas with a median household income of $150,000 or greater. These sites accommodate 99 units, or 0.8 percent of the total RHNA capacity analyzed. Of those unit s, 39 units are lower-income units, 19 units are moderate-income units, and 41 units are above moderate-income units.

The data shows that the proposed sites inventory is primarily located in moderate- and higher-income areas. Approximately 82.6 percent of total RHNA capacity is located in areas with median household incomes of $100,000 or greater. Similarly, approximat ely 83.7 percent of lower-income RHNA capacity is located in areas with median household incomes of $100,000 or greater.

What does this mean? This distribution supports AFFH objectiv es by providing substantial lower-income housing capacity in moderate- and higher-income areas, rather than concentrating lower-income capacity in lower-income areas of the City. This pattern can help expand housing choice and improve access to areas with stronger income characteristics.

Poverty Status
The City analyzed the proposed housing element sites in relation to poverty rates and noted the following key findings:
 102 housing element sites, or 61.1 percent of the sites inventory, are located in areas where the poverty rate is less than 10 percent. These site s accommodate 3,074 units, or 24.7 percent of the total RHNA capacity analyzed. Of those units, 995 units are lower-income units, 570 units are moderate-income units, and 1,509 units are above moderate-income units.  62 housing element sites, or 37.1 percent of the sites inventory, are located in areas where the poverty rate is between 10 and 19.9 percent. These sites accommodate 9,212 units, or 74.1 percent of the total RHNA capacity analyzed. Of those units, 3,031 units are lower-income units, 1,610 units are moderate-income units, and 4,571 units are above moderate-income units.  3 housing element sites, or 1.8 percent of the sites inventory, are located in areas where the poverty rate is between 20 and 29.9 percent. These sites accommo date 142 units, or 1.1 percent of the total RHNA capacity analyzed. Of those units, 48 units are lower-income units, 27 units are moderate-income units, and 67 units are above moderate-income units.  No housing element sites are located in areas where the poverty rate is 30 percent or greater. 394

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-123 The data shows that the sites inventory is not concentrated in areas with high poverty rates. Approximately

98.2 percent of housing element sites and 98.9 percent of total RHNA capacity are located in areas where the poverty rate is below 20 percent. Similarly, approximately 98.8 percent of lower-income RHNA capacity is located in areas where the poverty rate is below 20 percent.

What does this mean? This distribution supports AFFH objectives because the sites inventory does not concentrate the lower-income RHNA capacity in high-poverty areas. Instead, the lower-income RHNA capacity is primarily located in areas with compar atively lower poverty rates, which may help expand housing choice and reduce patterns of concentrated poverty.

Conclusion - What This Means for Fair Housing Choice
Overall, the proposed sites inventory supports AFFH objectives related to segregation and integration. The site-level and unit-capacity analysis shows that the inventory is not disproportionately concentrated in areas with higher concentrations of non-White populations, lower-income households, or high poverty rates. A majority of RHNA capacity, including lo wer-income RHNA capacity , is in areas where the predominant population is White alone, not Hispanic or Latino, and in areas with moderate- to higher- income characteristics.

The data shows that 86.2 percent of lower-income RHNA capacity is located in areas where the predominant population is White alone, not Hispanic or Latino, and 83.7 percen t of lower-income RHNA capacity is located in areas with median household incomes of $100, 000 or greater. In addition, 98.8 percent of lower-income RHNA capacity is located in areas where the poverty rate is below 20 percent, and no housing element sites are located in areas where the poverty rate is 30 percent or greater.

Together, these findings indicate that the sites inve ntory has the potential to expand housing choices in areas of the City with stronger income characteristics and lower levels of poverty, rather than concentrating lower-income capacity in areas already experiencing economic disadvantage. This distribution supports AFFH objectives by providing opportunities for fu ture housing development, including lower-income housing, in areas that may offer greater access to economic stability and opportunity.

B. Racially and Ethnically Concentrated Areas of Poverty (R/ECAP) and Affluence This section evaluates the sites inventory in relation to racially/ethnically concentrated areas of poverty and racially concentrated areas of affluence (RCAA). The analysis includes data for R/ECAP and RCAA tracts. 395

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-124

R/ECAP Tracts
Figure 3-27 shows the housing element sites in relation to Racially/Ethnically Concentrated Areas of Poverty. Figure 3-27 shows the following findings:
 No housing element sites are located within a R/ECAP tract. Therefore, 0 units, or 0 percent of the total RHNA capacity analyzed, are located within a R/ECAP tract.

396

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-125

Racially Concentrated Areas of Affluence
Figure 3-28 shows the housing element sites in relation to Racially Concentrated Areas of Affluence. Figure 3-28 shows the following findings:
 14 housing element sites, or 8.4 percent of the sites inventory, are located within a Racially Concentrated Area of Affluence. These sites accommodate 442 units, or 3.6 percent of the total RHNA capacity analyzed. Of those units, 148 units are lower-income units, 80 units are moderate- income units, and 214 units are above moderate-income units.

What does this mean? The data shows that the sites inventory is not concentrated in Racially Concentrated Areas of Affluence. However, the inventory does include some lower-income RHNA capacity within these 397

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-126 areas, including 148 lower-income units. This supports AFFH objectives by providing some opportunity for lower-income housing in more affluent areas of the City.

Conclusion - What This Means for Fair Housing Choice
Overall, the sites inventory supports AFFH objectives related to avoiding the concentration of housing capacity in areas of poverty. No housing element sites are located within R/ECAP tracts, and no sites are located in areas where the poverty rate is 30 percent or greater.

However, the City recognizes that the analysis also shows that the sites inventory includes a limited share of capacity in Racially Concentrated Areas of Affluence. Only 14 housing element sites, or 8.4 percent of the sites inventory, are located in RCAAs. These site s accommodate 442 units, or 3.6 percent of the total RHNA capacity, including 148 lower-income units, or 3.6 percent of the lower-income RHNA capacity. As a result, while the sites inventory does include some lo wer-income housing capacity in RCAAs, it does not place a substantial share of the RHNA capacity in these areas.

The limited share of capacity in RCAAs suggests that the sites inventory alone may not fully address patterns of exclusion from the City’s most affluent areas. However, the RCAA findings should be considered together with the broader access to opportunity and income findi ngs. Although only a limited share of capacity is located within RCAAs specifically, the sites inventory places a substantial majority of housing capacity in higher-opportunity areas. Specifically, 111 housing element sites, or 66.5 percent of the sites inventory, are located in High or Highest Resource areas. These sites accommodate 9,483 units, or 76.3 percent of the total RHNA capacity analyzed, including 3,101 lower-income units, or 76.1 percent of the lower-income RHNA capacity.

The income analysis also supports this finding. Th e sites inventory accommodates 10,261 units, or 82.6 percent of total RHNA capacity, in areas with median household inco mes of $100,000 or greater. This includes 3,409 lower-income units, or 83.7 percent of the lower-income RHNA capacity. Therefore, while the sites inventory has limited capacity in RCAAs, it does provide substantial lower-income housing capacity in higher-income and higher-resource areas of the City.

Therefore, although the sites inventory does not concentrate a large share of capacity within RCAAs specifically, it does provide significant lower-income housing capacity in higher-income areas of the city.

This distinction is important because RCAAs are one measure of affluence, but they are not the only indicator of access to higher-income neighborhoods or economic opportunity. When evaluated against median household income and TCAC Opportunity Area data, the sites inventory provides substantial capacity in areas with stronger income and opportunity characteristics.

The City’s ADU strategy also plays an important role in addressing this finding. Unlike larger housing element sites, which depend on parcel size, zoning, redevelopment feasibility, and realistic capacity assumptions, ADUs may be developed on residential parcels throughout the City, including in higher- income and lower-density neighborhoods where larger multifamily opportunity sites may be limited. To 398

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-127 the extent ADUs are anticipated in RCAA or higher-income areas, they can help expand lower-cost housing opportunities in neighborhoods that may otherwise have limited multifamily development capacity.

Over the first five years of the pl anning period (2021 – Current), the City permitted a total of 374 ADUs, exceeding the original projection of 250 ADUs for the 8-year planning period. This demonstrates that actual ADU permitting has outpaced the assumptions included in the 2021 Housing Element, particularly in later years as property owner familiarity, streamlined regulations, and local implementation efforts have continued to support ADU development. Completed ADUs have also increased steadily over time, reflecting the typical lag between permitting and construction while confirming that ADUs are being delivered as part of the City’s housing supply.

From an AFFH perspective, continued ADU producti on supports the City’s broader strategy to expand housing opportunities throughout existing reside ntial neighborhoods, including areas where larger multifamily Housing Element sites may be limited. While ADUs are not relied upon in this amendment to satisfy RHNA capacity, they remain an important t ool for increasing housing choice in established neighborhoods, including single-family and lower-dens ity areas. This is particularly relevant in areas identified as Racially Concentrated Areas of Afflue nce, where the availability of traditional multifamily sites may be more limited. By allowing additional hous ing units within existing residential lots, ADUs can help incrementally diversify housing options, support smaller households, older adults, caregivers, and extended families, and create additional rental oppo rtunities in neighborhoods with access to schools, services, and amenities.

399

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-128 C. Access to Opportunities
This section evaluates the housing element sites invent ory in relation to access to opportunity indicators, including TCAC/HCD Opportunity Area designations a nd environmental conditions. These indicators help evaluate whether future housing capacity, including lo wer-income RHNA capacity, is located in areas with greater access to economic, educational, environmental, and other opportunity-related resources.

Tax Credit Allocation Committee/HCD Opportunity Areas
Figure 3-29 shows the housing element sites in relation to TCAC/HCD Opportunity Area designations. Figure 3-29 shows the following findings:
 70 housing element sites, or 41.9 percent of the sites inventory, are located in Highest Resource areas. These sites accommodate 8,320 units, or 66.9 percent of the total RHNA capacity analyzed.

Of those units, 2,736 units are lower-income uni ts, 1,426 units are moderate-income units, and 4,158 units are above moderate-income units.
400

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-129  41 housing element sites, or 24.6 percent of the sites inventory, are located in High Resource areas.

These sites accommodate 1,163 units, or 9.4 percent of the total RHNA capacity analyzed. Of those units, 365 units are lower-income units, 214 units are moderate-income units, and 584 units are above moderate-income units.
 34 housing element sites, or 20.4 percent of the sites inventory, are located in Moderate Resource areas. These sites accommodate 2,160 units, or 17.4 percent of the total RHNA capacity analyzed.

Of those units, 692 units are lower-income units, 434 units are moderate-income units, and 1,034 units are above moderate-income units.
 22 housing element sites, or 13.2 percent of the sites inventory, are located in Low Resource areas.

These sites accommodate 785 units, or 6.3 percent of the total RHNA capacity analyzed. Of those units, 281 units are lower-income units, 133 units are moderate-income units, and 371 units are above moderate-income units.

The data shows that the sites inventory is strongly oriented towards higher-opportunity areas. Combined, 111 housing element sites, or 66.5 perc ent of the sites inventory, are loca ted in High or Highest Resource areas. These sites accommodate 9,483 units, or 76.3 percent of the total RH NA capacity analyzed.

Importantly, these High and Highes t Resource sites also accommodate 3,101 lower-income units, or 76.1 percent of the lower-income RHNA capacity.

What does this mean? This distribution supports AFFH objectives by placing a substantial majority of total housing capacity and lower-income housing capacity in areas with greater access to opportunity. The data indicates that the sites in ventory does not concentrate lower-income RHNA capacity in Moderate or Low Resource areas. Instead, the majority of lower-income RHNA capacity is located in High and Highest Resource areas, which may improve access to economic, educational, environmental, and other resources for lower-income households.

Environmental Conditions / CalEnviroScreen
The City also analyzed housing element sites in relation to CalEnviroScreen scores. Lower CalEnviroScreen scores generally indicate lower environmental burden, while higher scores indicate higher environmental burden. Key findings included:
 20 housing element sites, or 12.0 percent of the sites inventory, are located in areas with a CalEnviroScreen score below 25. These sites acco mmodate 599 units, or 4.8 percent of the total RHNA capacity analyzed. Of those units, 208 units are lower-income units, 109 units are moderate- income units, and 282 units are above moderate-income units.  102 housing element sites, or 61.1 percent of the sites inventory, are located in areas with a CalEnviroScreen score between 25 and 49.9. Th ese sites accommodate 10,080 units, or 81.1 percent of the total RHNA capacity analyzed. Of those units, 3,291 units are lower-income units, 1,781 units are moderate-income units, and 5,008 units are above moderate-income units. 401

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-130  23 housing element sites, or 13.8 percent of the sites inventory, are located in areas with a CalEnviroScreen score be tween 50 and 74.9. These sites acco mmodate 964 units, or 7.8 percent of the total RHNA capacity anal yzed. Of those units, 294 units ar e lower-income units, 184 units are moderate-income units, and 486 units are above moderate-income units.  22 housing element sites, or 13.2 percent of the sites inventory, are located in areas with a CalEnviroScreen score of 75 or greater. These sites accommodate 785 units, or 6.3 percent of the total RHNA capacity analyzed. Of those units, 281 units are lower-income units, 133 units are moderate-income units, and 371 units are above moderate-income units.

What does this mean? The data shows that most housing capacity is located in areas with lower to moderate environmental burden. Approximately 85.9 perc ent of total RHNA capacity is located in areas with CalEnviroScreen scores below 50. Similarly, 85.9 percent of lower-income RHNA capacity is located in areas with CalEnviroScreen scores below 50.

Only 6.3 percent of total RHNA capacity and 6.9 percent of lower-income RHNA capacity are located in areas with CalEnviroScreen scores of 75 or greater. This indicates that the sites inventory does not disproportionately place lower-income RHNA capacity in areas with the highest environmental burden.

Conclusion - What This Means for Fair Housing Choice
Overall, the sites inventory strongly supports AFFH objectives related to access to opportunity. A substantial majority of total RHNA capacity and lower-income RHNA capacity is located in High or Highest Resource areas. Specifically, 76.3 percent of total RHNA capaci ty and 76.1 percent of lowe r-income RHNA capacity are located in High or Highest Resource areas. This is a strong finding because it shows that the City is not simply accommodating lower-income RHNA capacity in lower-resource areas but is instead identifying meaningful capacity in areas with greater access to opportunity.

The CalEnviroScreen analysis also supports this co nclusion. Approximately 85.9 percent of total RHNA capacity and 85.9 percent of lower-income RHNA capacity are located in areas with CalEnviroScreen scores below 50. This indicates that most of the sites inventory is located outside areas with comparatively higher environmental burden.

Comparison to 2021 Housing Element Sites Inventory
The updated sites inventory reflects a stronger distribu tion of housing capacity in relation to TCAC/HCD Opportunity Areas than the sites inventory analyzed in the 2021 Housing Element. This improvement appears to reflect two related factors: the addition of new housing element sites are more broadly distributed throughout th e City and no longer concentrated north of the I-405 and changes in the underlying fair housing datasets and opportunity area designations over time.

The TCAC/HCD Opportunity Maps are updated regularly and are intended to identify areas associated with positive economic, educational, and health outcomes for lower-income families. Because the maps are periodically updated, changes between the 2021 analysis and the current analysis may reflect both changes 402

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-131 to the City’s sites inventory and changes in how areas are classified under the current TCAC/HCD methodology and data. (Cal HCD)
The housing element submitted origin ally in 2021 found that the majority of potential units were located in Moderate Resource areas, with only a limited sh are of capacity located in High Resource areas.

Specifically, the 2021 inventory included 9 sites in High Resource areas, acco mmodating 578 units, or 3.5 percent of total potential units. Of those units, 165 units were affordable to lower-income households. The 2021 analysis also identified 17 site s in High Segregation and Poverty areas and 10 sites in Low Resource areas, together accommodating 1,595 units, or 9.6 pe rcent of total potential units, including 498 lower- income units.

By comparison, the updated sites inventory reflected in this 2026 amendment includes 111 housing element sites in High or Highest Resource areas, accommodating 9,483 units, or 76.3 percent of the total RHNA capacity analyzed. These sites include 3,101 lower-income units, or 76.1 percent of the lower-income RHNA capacity. The updated inventory also includes a smaller share of capacity in Low Resource areas, with 22 housing element sites accommodati ng 785 units, or 6.3 percent of total RHNA capacity, including 281 lower-income units, or 6.9 percent of lower-income RHNA capacity.

The updated AFFH data also shows that Costa Mesa now includes areas classified as Highest Resource and areas identified as Racially Concentrated Areas of Affluence, which were not reflected in the same way in the 2021 sites inventory analysis. This suggests that, under current TCAC/HCD and AFFH datasets, portions of Costa Mesa demonstrate stronger opportunity and a ffluence characteristics than were reflected in the prior analysis. However, because opportunity maps and AFFH layers are updated over time, this change should be understood as a combination of updated si te selection, updated data, and changes in mapped opportunity classifications.

Overall, while the 2021 and 2026 updated analyses are not perfectly comparable, the current sites inventory demonstrates a substantially improved fair housing outcome. The updated inventory places a much larger share of total and lower-income RHNA capacity in High and Highest Resource areas and a smaller share of capacity in lower-resource areas. This improved distribution supports the City’s AFFH objectives by expanding the potential for lower-income households to access higher-opp ortunity neighborhoods while reducing the relative concentration of future housing capacity in lower-resource geographies.

D. Disproportionate Housing Needs
This section evaluates the housing element sites inventory in relation to indicators of disproportionate housing needs, including displacement risk, over crowding, and housing overpayment by renters and homeowners. These indicators help assess whether the sites inventory may concentrate future housing capacity in areas already experiencing housing inst ability, or whether the inventory can help address existing housing needs through new housing opportunities.

403

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-132

Displacement Risk
Figure 3-30 shows the housing element sites in relation to displacement risk. Figure 3-30 shows the following findings:
 43 housing element sites, or 25.7 percent of the sites inventory, are located in areas identified as At Risk of Displacement. These sites accommodate 1,672 units, or 13.5 percent of the total RHNA capacity analyzed. Of those units, 548 units are lower-income units, 302 units are moderate- income units, and 822 units are above moderate-income units.  124 housing element sites, or 74.3 percent of the sites inventory, are located in areas identified as having Lower Displacement Risk . These sites accommodate 10,756 units, or 86.5 percent of the total RHNA capacity anal yzed. Of those units, 3,526 units are lower-income units, 1,905 units are moderate-income units, and 5,325 units are above moderate-income units. 404

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-133 What does this mean? This distribution supports AFFH objectiv es because the sites inventory does not disproportionately place future housing capacity in areas where existing residents may be more vulnerable to displacement. Although 25.7 percent of housing element sites are located in areas identified as at risk of displacement, these sites accommodate only 13.5 percent of total RHNA capacity. By contrast, the substantial majority of total and lower-income capacity is located in areas with lower displacement risk.

Meaningful Actions: At the same time, the presence of 548 lo wer-income units in areas at risk of displacement is important. Lower-income housing capa city in these areas can help respond to existing housing displacement risks by creating opportun ities for deed-restricted affordable housing in neighborhoods where lower-income residents may otherwise face increasing housing pressure.

The City has already established programs to help re spond to displacement risk and housing affordability pressures. In 2024, the City adopted its first Inclusio nary Housing Ordinance, Title 13, Chapter XVII of the Zoning Code which is intended to increase the production of affordable housing as new residential development occurs. This program is especially relevant for sites located in areas at risk of displacement because it helps ensure that new housing production in cludes affordable units and does not only result in market-rate development.

To support the implementation of the Inclusionary Housing Ordinance, the City has also allocated $2.5 million to an affordable housing trust fund. As part of the adoption of the Inclusionary Housing Ordinance, the City committed to monitoring the effectiveness of the ordinance with the intent to return to City Council for an update on implementation and opportuni ty to consider potential modifications to in-lieu fees, as needed, to strengthen affordable housing outcomes.

Through Program 2A: Inclusionary Housing Ordinance , the City will assess the ordinance for effectiveness and recommend changes, as needed. This work is scheduled to be completed by December 2027 and will be led by the City of Costa Mesa Economic and De velopment Services Department, including the Housing and Community Development Division and Planning Divi sion. This program supports AFFH objectives by helping expand access to affordable housing, including in areas where residents may be vulnerable to displacement or housing cost pressures.

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-134

Overcrowding
Figure 3-31 shows the housing element sites in relation to overcrowding rates. Figure 3-31 shows the following findings:
 80 housing element sites, or 47.9 percent of the sites inventory, are located in areas where overcrowding is less than 5 percent. These site s accommodate 9,328 units, or 75.1 percent of the total RHNA capacity anal yzed. Of those units, 3,036 units are lower-income units, 1,637 units are moderate-income units, and 4,655 units are above moderate-income units.  60 housing element sites, or 35.9 percent of the sites inventory, are located in areas where overcrowding is between 5 and 9.9 percent. These sites accommodate 2,127 units, or 17.1 percent of the total RHNA capacity anal yzed. Of those units, 697 units ar e lower-income units, 402 units are moderate-income units, and 1,028 units are above moderate-income units. 406

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-135  27 housing element sites, or 16.2 percent of the sites inventory, are located in areas where overcrowding is 10 percent or greater. These si tes accommodate 973 units, or 7.8 percent of the total RHNA capacity analyzed. Of those units, 341 units are lower-income units, 168 units are moderate-income units, and 464 units are above moderate-income units.

The data shows that most RHNA capacity is located outside areas with higher overcrowding rates.

Approximately 75.1 percent of total RHNA capacity and 74.5 percent of lower-income RHNA capacity are located in areas where overcrowding is less than 5 percent. Only 7.8 percent of total RHNA capacity and 8.4 percent of lower-income RHNA capacity are located in areas where overcrowding is 10 percent or greater.

What does this mean? This distribution indicates that the site s inventory does not disproportionately concentrate housing capacity in areas already experien cing higher levels of overcrowding. At the same time, the inclusion of some housing capacity in area s with higher overcrowding may help address local housing needs by increasing the supply of housing in areas where existing households may be experiencing pressure from limited housing availability.

407

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-136 Housing Overpayment by Renters
Figure 3-32 shows the housing element sites in relation to the percentage of renter households experiencing housing overpayment.
 46 sites, or 27.5 percent of the sites inventory, are located in areas where less than 50 percent of renter households are overpayi ng for housing. These sites accommodate 1,164 units, or 9.4 percent of the total RHNA capacity analyzed. Of those units, 417 units are lower-income units, 198 units are moderate-income units, and 549 units are above moderate-income units.  108 sites, or 64.7 percent of the sites inventory, are located in areas where 50 to 59.9 percent of renter households are overpaying for housin g. These sites accommodate 10,797 units, or 86.9 percent of the total RHNA capacity analyzed. Of those units, 3,497 units are lower-income units, 1,920 units are moderate-income units, and 5,380 units are above moderate-income units.  13 sites, or 7.8 percent of the sites inventory, are located in areas where 60 percent or greater of renter households are overpaying for housing. These sites accommodate 467 units, or 3.8 percent of the total RHNA capacity analyzed. Of those units, 160 units are lower-income units, 89 units are moderate-income units, and 218 units are above moderate-income units.

The renter overpayment data shows that housing co st burden is a widespread issue in Costa Mesa. A substantial majority of the sites inventory is located in areas where at least half of renter households are overpaying for housing. Specifically, 121 housing element sites, or 72.5 percent of the sites inventory, are located in areas where renter overpayment is 50 percent or greater. These sites accommodate 11,264 units, or 90.6 percent of the total RHNA capacity an alyzed, including 3,657 lowe r-income units, or 89.8 percent of the lower-income RHNA capacity.

What does this mean? This finding should be framed carefully. The high share of RHNA capacity in areas with renter overpayment does not necessarily indicate that the sites inventory is worsening disproportionate housing needs, because renter overpayment appears to be broadly distributed across the city. Rather, the data indicates that renter cost burden is a citywide housing issue. The inclusion of significant lower-income RHNA capacity in these areas may help address existing affordability needs by increasing opportunities for income-restricted and lower-cost housing. Additionally, increasing the capacity for housing development across the community on Housing Element sites as well as non-Housing Element sites has the potential to increase supply throughout the City, potentially reducing rental prices and overpayment in general.

Housing Overpayment by Homeowners
Additionally, the City analyzed the housing element sites in relation to the percentage of homeowner households experiencing housing overpayment. Key findings included:
408

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-137  8 housing element sites, or 4.8 percent of the sites inventory, are located in areas where homeowner overpayment is less than 20 percent. These sites accommodate 1,041 units, or 8.4 percent of the total RHNA capacity analyzed. Of those units, 336 units are lower-income units, 224 units are moderate-income units, and 481 units are above moderate-income units.  106 housing element sites, or 63.5 percent of th e sites inventory, are located in areas where homeowner overpayment is between 20 and 39.9 percent. These sites accommodate 9,684 units, or 77.9 percent of the total RHNA capacity analyzed. Of those units, 3,176 units are lower-income units, 1,679 units are moderate-income units, and 4,829 units are above moderate-income units.  53 housing element sites, or 31.7 percent of the sites inventory, are located in areas where homeowner overpayment is 40 percent or greate r. These sites accommodate 1,703 units, or 13.7 percent of the total RHNA capacity analyzed. Of those units, 562 units are lower-income units, 304 units are moderate-income units, and 837 units are above moderate-income units.

The data shows that most RHNA capacity is located in areas with moderate levels of homeowner overpayment. Approximately 77.9 percent of total RHNA capacity and 78.0 percent of lower-income RHNA capacity are located in areas where homeowner overpayment is between 20 and 39.9 percent. A smaller share, approximately 13.7 percent of total RHNA capacity and 13.8 percent of lower-income RHNA capacity, is located in areas where homeowner overpayment is 40 percent or greater.

What does this mean? This distribution indicates that the site s inventory does not disproportionately concentrate housing capacity in areas with the highest levels of homeowner overpayment. However, the presence of homeowner overpayment across many areas of the city reinforces the need for a broad housing strategy that includes both rental and owne rship opportunities, affordable housing production, and programs that support housing stability.

Conclusion - What This Means for Fair Housing Choice
Overall, the sites inventory generally does not concentrate RHNA capacity in areas with the highest indicators of disproportionate housing need. A substantial majority of total and lower-income capacity is located in areas with lower displacement risk, lower overcrowding rates, and moderate levels of homeowner overpayment.

Specifically, 86.5 percent of total RHNA capacity and 86.5 percent of lower-income RHNA capacity are located in areas with lower displacement risk, while 75.1 percent of total RHNA capacity and 74.5 percent of lower- income RHNA capacity are located in areas where overcrowding is less than 5 percent.

However, the renter overpayment data shows that housing affordability pressures are widespread throughout Costa Mesa. Approximately 90.6 percent of total RHNA capacity and 89.8 percent of lower- income RHNA capacity are located in areas where at least half of renter households are overpaying for housing. This should not be interpreted as a disproportionate concentration of capacity in a small high- need area; rather, it indicates that renter cost burden is a broad citywide condition. The sites inventory can help respond to this need by crea ting opportunities for new housing, including lower-income housing, in areas where renter households are experiencing affordability pressure. 409

8. Analysis of Fair Housing Priorities and Goals
To enhance mobility and promote inclusion for protected classes, the chief strategy included in this Housing Element is to provide sites suitable for affordable housing in high-resource, high-opportunity areas, as demonstrated by the analysis of the housing resource sites contained in Chapter 3: Housing Resources .

Other programs that affirmatively further fair housing and implement the AI’s recommendations include:
 PROGRAM 2A: Inclusionary Housing Ordinance
 PROGRAM 2B: Affordable Housing Development
 PROGRAM 2C: Supportive Services for Persons with Special Needs  PROGRAM 2D: Facilitate Development of Senior Housing Options  PROGRAM 2E: Encourage Development of Housing Options for Large-Family Households  PROGRAM 2F: Persons with Physical and Developmental Disabilities  PROGRAM 2H: Farmworker Housing
 PROGRAM 4A: Fair Housing
 PROGRAM 4B: Rental Housing Assistance
 PROGRAM 4D: Fair Housing Assistance
 PROGRAM 4E: Low Barrier Navigation Centers
 PROGRAM 4F: Homeless Shelter
The following table also lists fair housing issues identified and relevant programs included in the Housing Plan addressing each.

Local Meaningful Actions
Since adoption of the 2021 Housing Element, the City has initiated and completed several meaningful actions to address land use constraints, expand hous ing opportunities, facilitat e housing production, and affirmatively further fair housing. These actions include updates to zoning, development standards, permit procedures, and local housing programs intended to increase residential capacity, provide greater certainty for housing development, and support a broader distribution of housing opportunities throughout the City.

While these actions are discussed throughout this chapter, they are summarized below to demonstrate the City’s continued progress in implementing the Housing Element and addressing fair housing issues  Community Engagement / Neighborhoods Where We All Belong. The City is conducting extensive community engagement as part of fair housing actions identified in Program 4A. The Neighborhoods Where We All Belong initiative is a comprehensive effort to address housing needs in Costa Mesa. Through this process, the City is engaging the community about future housing opportunities and proposed updates to the Zoning Code, specific plans, General Plan overlays, and creating Objective Design Standards. This outreach is helping to inform the City’s approach to Housing Element implementation, Measure K implementation, and broader changes intended to expand housing opportunities, reduce constraint s, and support fair housing objectives. The initiative was recently recognized by the American Planning Association Orange Section with a 2026 410

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-139 Award of Merit in the Opportunity and Empowerment category for the Neighborhoods Where We All Belong Round One Community Visioning.
 Inclusionary Housing Program. As part of addressing housing mobility, the City included Programs 2A and 4A to help respond to di splacement risk and housing affo rdability pressures. In 2024, the City adopted its first Inclusionary Housing Ordinance to increase the production of affordable housing as new residential development occurs. This program is especially relevant for sites located in areas at risk of displacement because it helps ensure that new housing production includes affordable units and does not result solely in market-rate development. To support implementation of the Inclusionary Housing Ordina nce, the City has also allocated $2.5 million to an affordable housing trust fund. As part of adopting the ordinance, the City committed to monitoring its effectiveness and returning to the City Council with an implementation update and an opportunity to consider potential modificati ons to in-lieu fees, as needed, to strengthen affordable housing outcomes.
 Voter Initiated Measures. Through Program 3G, the City had committed to evaluating voter- initiated measures such as Measure Y as a constraint on housing. In 2022, Measure K was approved by Costa Mesa voters. Measure K provides an important local framework for expanding housing opportunities in commercial, industrial, and mixed- use areas while preserving existing residential neighborhoods. Through Measure K implementati on, the City is creating opportunities for additional residential and mixed-use development in areas closer to jobs, services, transit, and amenities. This effort supports the City’s fair housing goals by expanding housing choice and creating additional capacity beyond the minimum RHNA obligation.  Mixed-Use Overlay District (MUOD). The City is currently amending the MUOD to facilitate residential and mixed-use development on Housing Element sites and additional Measure K sites.

In April 2026, the City amended th e MUOD to establish specific provisions for Housing Element Opportunity Sites and adopted a revised zoning map to apply the MUOD to those sites. Scheduled for Fall 2026, the City is also advancing a broade r MUOD update to apply the overlay to Measure K sites beyond the Housing Element inventory. Th is phased effort increase s residential capacity, creates clearer development standards, and supports a more comprehensive approach to housing production beyond RHNA compliance.
 Design. As part of completed Program 3S, the City is preparing Objective Design Standards to replace the design review process to provide clea rer, more predictable standards for residential and mixed-use development. These standards are in tended to reduce subjectivity in the review process, provide greater certainty to applican ts, and support streamlined review of housing projects consistent with State law.
 Housing Element Rezoning. As committed in Programs 3C, 3D and 3N, the City completed rezoning actions for Housing Element sites to ensure adeq uate capacity to accommodate the RHNA. These actions included applying the MUOD to Housing Element sites and establishing development criteria intended to encourage and facilitate residential development. The amended sites inventory also results in a broader distribution of Housing Element sites throughout the City, rather than a concentration primarily north of I-405. Lastly, the revised inve ntory identifies capacity for approximately 15,000 units, exceeding the City’s RHNA obligation and providing an approximately 411

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-140 28 percent buffer. This additional capacity supports the City’s ability to accommodate its RHNA while providing flexibility to account for potent ial changes in site availability, development feasibility, and project timing over the remainder of the planning period.  Development Standards. Pursuant to Program 2M, the City has updated development standards, including standards related to parking, building heig ht, and residential density, to better facilitate housing development. These changes are intended to reduce barriers to residential development and support a broader range of housing types.

Accessory Dwelling Units. The City implemented Programs 3E and 3M to support ADU production as a meaningful component of the City’s housing supply. Although the amended Housing Element no longer relies on projected ADU production to satisfy RHNA capacity, actual ADU permitting has exceeded the assumptions included in the 2021 Housing Element. Continued ADU production supports housing choice in existing residential neighborhoods, including areas where larger multifamily Housing Element sites may be limited.

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-144 F. Housing Resources

1. Regional Housing Needs Allocation
This section of the Housing Element provides an overview of the resources available to the City to meet the Regional Housing Needs Allocation (RHNA). The City of Costa Mesa is required to plan for the following 2021-2029 RHNA allocation:

Future Housing Needs
Future housing need refers to the share of the regional housing need that has been allocated to the City.

The State Department of Housing and Community Development (HCD) has supplied a regional housing goal to the Southern California Associat ion of Governments (SCAG). SCAG was then required to allocate the housing goal to each jurisdiction within the region th rough a RHNA Plan. In alloca ting the region’s future housing needs to jurisdictions, SCAG is required to take the following factors into consideration pursuant to Section 65584 of the State Government Code:
 Market demand for housing;
 Employment opportunities;
 Availability of suitable sites and public
facilities;
 Commuting patterns;
 Type and tenure of housing;
 Loss of units in assisted housing
developments;
 Over-concentration of lower income
households; and
 Geological and topographical
constraints.

HCD, through a determination process, allocates units to each region across California. It is then up to each region to determine a methodology and process for allocating units to each jurisdiction within that region.

SCAG adopted its Regional Housing Needs Allocation (RHNA Plan) in Ma rch 2021. This RHNA covers an 8- year planning period (starting in 2021) and addresses housing i ssues that are related to future growth in the region. The RHNA allocates to each city and coun ty a “fair share” of the region’s projected housing needs by household income group. The major goal of th e RHNA is to assure a fair distribution of housing among cities and counties within the SCAG region, so that every community provides an opportunity for a mix of housing for all economic segments.

Costa Mesa’s share of the SCAG regional growth al location is 11,760 new units for the current planning period (2021-2029). Table 3-36: Housing Needs for 2021-2029, indicates the City’s RHNA need for the stated planning period.

Residential Sites Inventory
Appendix B of the Housing Element includes the required site analysis tables and site information for the vacant and non-vacant properties to meet the City’s RHNA need through the 2021-2029 planning period.

The following discussions summarize the City’s site inventory and adequate sites identification strategy.

Adequacy of Sites for RHNA
The City of Costa Mesa conducted a thorough analysis of all parcels within the City to determine which areas may have the most realistic potential to redevelo p for residential uses within the planning period.

The analysis included an in depth look at the following site characteristics for each parcel within the inventory:
 Address
 Ownership
 Zoning (including Specific Plan areas, Urban Plans, and Overlays, if applicable)  Size (Net developable acres removing known development constraints)  Density
 Vacancy status
 Previous Housing Element identification
 Potential Development Capacity (Dwelling Units) by income category  Description of existing use
Most sites identified meet AB 1397 requirements for size as well as infrastructure requirements for available utility service. There is a further analysis regarding consolidation of small sites as well as the development potential of large sites within Appendix B.

The City of Costa Mesa has a total 2021-2029 RHNA allocation of 11,760 units. The Housing Element update lists sites, including accessory dwelling units, that can accommodate approximately 17,531 additional units.

Table 3-37 shows a summary of the City’s overall capacity to accommodate its RHNA. Overall, the City has adequate capacity to accommodate its 2021-2029 RHNA with a 30% buffer in excess of the City’s RHNA need.

Development projects that are in the planning process but have not received approvals or building permits are considered “in the pipeline.” For applications submitted for a land use approval, projects are considered “pending” until the necessary land use approvals are issued, at which point a project is deemed “approved.” Once a building permit is issued, the project is identified as “building permit issued.” When project construction is completed and all necessary building sa fety inspections have been completed a certificate of occupancy or “final building permit” is issued.

While the City has several projects in the development pipeline, it does not rely on pipeline projects to meet its RHNA obligations. Instead, pipeline projects are reviewed to understand prevailing development trends and to inform site selection. The characteristics of submitted projects helped guide the identification of suitable sites for inclusion in the inventory.

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-147 Redevelopment of Non-Vacant Sites for Residential Uses
The City of Costa Mesa does not have sufficient va cant land available to accommodate fifty percent of their low/very-low income RHNA and are reliant on non-vacant sites to meet their RHNA need. To accommodate the need at all income levels, the City has analyzed sites within non-residentially zoned areas that permit residential development through Specif ic Plans, Urban Plans, or Overlays. The City also evaluated and included parcels not currently within Urban Plans which will be added when those Urban Plans are amended.

As part of the candidate housing sites analysis, the City has evaluated recent projects that have redeveloped within non-residentially zoned areas that included re sidential units. Those projects, including the zoning, use prior to redevelopment, and a project analysis of the approved development plan, are shown in Table 3-38. The City’s analysis showed that prior uses on these redeveloped sites were similar in nature to the existing uses on sites identified within the sites inventory in Table B-6.

The City has also conducted a parcel specific analysis of existing uses for each of the identified sites. This analysis of existing uses, including indicators of a likelihood that the ex isting use will redevelop within the next eight years, are provided in Table B-9. This analysis is based on information readily available to the City and research that can be found through online research. The City does not always have access to private lease information but has included informatio n that property owners have shared regarding individual sites.

Table B-5 summarizes recent, approved, entitled, and constr ucted residential and mixed-use projects in Costa Mesa to demonstrate local redevelopment pa tterns and the City’s experience converting underutilized commercial, industrial, motel/hotel, office, and vacant sites into housing. The table identifies each project’s location, acreage, unit count, densit y, zoning, prior use, development classification, TCAC/HCD resource area, and relationship to similar sites included in the Housing Element sites inventory.

Together, these examples show that residential development has occurred across multiple areas of the City and that many projects have been built or approved on sites with characteristics similar to those identified in the sites inventory.

Lease Analysis
Existing lease agreements on infill and non-vacant properties present a potential impediment that may prevent residential development within the planning peri od. State law requires the City to consider lease terms in evaluating the use of non-vacant sites, ho wever the City does not have access to private party lease agreements or other contractual agreements am ongst private parties. Additionally, COVID-19 has increased the potential number of vacancies, especially within commercial uses. As part of the sites analysis for very-low and low-income sites, the City conducted discussions with property owners who felt comfortable sharing this information and came forward as interested in developing their properties for housing through the planning period. Notes regarding discussion are found in Table B-9.

Regulatory Incentives
Density bonus is a State law which permits increased density, a lowered parking standard, and concessions for projects which provide a certain percentage of their dwelling units as deed restricted to residents at the 419

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-148 very-low, low, and moderate-income levels. Projects within infill areas such as Costa Mesa often utilize density bonus provisions to construct affordable units. The City understands that existing land use policy may not necessarily contribute to the development of housing. Therefore, regulatory incentives can be helpful in bringing housing units to the market. The City has committed through Program 2I, to annually update the local density bonus ordinance to be consistent with State law if changes are adopted at the State level.

The City has created programs expressly written to address the analysis and potential development of additional regulatory incentives to incentivize the creation of affordable housing. As stated in Program 2B, these may include, but are not limited to, the following for projects that propose a percentage of their housing units as affordable:
 Deferment of fees
 Priority Processing
 Modified development standards (above and beyond what is permitted under Density Bonus) Development Trends and Current Market Demand for Existing Uses The existing uses within the identified candidate ho using sites are primarily commercial, light industrial, and office/business park. The following excerpts ar e from the Winter 2021 Allen Matkins/UCLA Anderson Forecast Commercial Real Estate Survey.

Office Space Markets
The COVID-19 pandemic took a toll on traditional office uses when the majority of California’s office workforce was required to work from home. This taught employees and employers that remote work was possible and may have sparked a trend of more remote work options in a post-COVID world. An excerpt from the above referenced study indicated that “survey participants are confident about the growth in demand for office space between 2020 and 2023, they are pessimistic abou t the return to investment in new space today.”
8 This indicates that while we may return to a more normal work setting in the short term, there is likely to be less investment going forward in new office space as employers look to downsize the leasable space they occupy and expand flexible work options to keep employees happy and hard costs down. It is likely this trend occurs into the next decade, opening up existing office uses not operating at full occupancy for residential redevelopment opportunities.

Retails Space Markets
In regard to future retail development trends and demand, the above referenced study noted the following observations from their analysis on participant responses. “During the previous economic expansion, retail space struggled. The current recession tripled down on that struggle. First, the loss of household income and the shelter-in-place policies reduced current demand for brick-and-mortar retail. Second, the inability to physically frequent many retail establishments created a new set of online shoppers, and third, increases

8 Allen Matkins/UCLA Anderson Forecast Commercial Real Estate Survey, Winter 2021, 420

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-149 in the savings rate on the part of households in response to the recession portends less individual consumption. To be sure, some activities will be coming back, particularly personal services and experiential retail. But now, more marginal properties will not fi nd tenants willing to pay sufficient rent to keep the properties in the retail space.”9
While COVID-19 had a large impact on retail in the i mmediate future, overall market trends pointed to a decline in the need for brick-and-mortar retail spaces going back over the past decade. The rise in online retailers such as Amazon a nd the shift in focus to online sales of major retailers like Target, Walmart, and others have kept shoppers in their homes and away from smaller mom and pop retailers as well.

Experiential uses such as restaurants and dining pr ovide more incentive and are likely to bounce back quickly following the removal of COVID-19 protocols. These uses do well in walkable, mixed-use settings with a strong flow of permanent consumers. Resident ial uses, especially at high er densities, present an opportunity to support future commercial growth incl uding supporting smaller mom and pop retailers in infill settings such as Costa Mesa.

Development Trends
State, regional, and local policy direction promoting the development of housing at all levels to meet existing housing shortages, especially for low-income families, has further driven up the demand for housing. The redevelopment of existing non-vacant land, both in residential and non-residential zones, for multi-family rental and for sale housing provides a re alistic opportunity to create affordable housing using the resources available within communities such as Costa Mesa. As a result, much of Costa Mesa’s future growth will be on infill opportunities within the City. To facilitate this, the City has proposed actions to evaluate and revise the development standards and permitted uses within many key areas within the City.

This increases the developable area within the City where residential development can occur and promotes development at densities which may support affordable housing.

As stated previously, much of Costa Mesa’s anticipated future housing growth is expected to occur on infill sites, or sites with existing us es. Development on non-vacant parcels was analyzed to determine a reasonable development capacity based on known cons traints and historic deve lopment patterns within each of the different zones. Table B-9 in Appendix B contains a detailed description of each existing use.

Many of the existing uses were found to be simila r with recent redevelopment examples in Costa Mesa.

Appendix A also includes outreach to property owners and letters of owner support/developer interest for specific parcels identified in the Housing Element.

Accessory Dwelling Unit Productions
Accessory dwelling units, or ADUs) are housing units which may be developed in addition to an existing single- or multi-family residential use. These housin g units can be free-standing or attached to a primary structure and are intended to provide additional housing on an existing residential lot. Often ADUs provide housing for family members or are rented to members of the community.

9 Allen Matkins/UCLA Anderson Forecast Commercial Real Estate Survey, Winter 2021, 421

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-150 A number of State Assembly and Senate Bills were passed in 2018 and 2019 that promote development of ADUs and remove barriers that may inhibit their development within communities. The following is a summary of those bills:
 AB 68 and 881
o Prohibit minimum lot size requirements
o Cap setback requirements at 4’, increasing the size and location opportunities for ADUs o Prohibit the application of lot coverage, FA R, or open space requirements that would prevent an 800 square foot from being developed on a lot o Remove the need for replacement parking when converting an existing garage to an ADU o Limit local discretion in establishing min and max unit size requirements o Mandate a 60-day review period for ADU applications through a non-discretionary process  SB 13
o Prohibit owner-occupancy requirements for 5 years
o Reduce impact fees applicable to ADUs
o Provide a program for homeowners to dela y compliance with certain building code requirements that do not relate to health and safety
 AB 670
o Prohibits Homeowner’s Associations (HOAs) from barring ADUs As a result of new legislation and an increased effort by the City to promote ADUs, the City has seen an increase in applications since 2021. Over the first four years of the planning period (2021-2025), the City permitted a total of 374 ADUs, significantly exceeding the original annual projection of 50 units per year.

This demonstrates that actual ADU production has outpaced initial expectations, particularly in later years as market familiarity, streamlined regulations, and local incentives have taken effect. Completed units have also increased steadily over time, reflecting a lag between permitting and construction but confirming sustained delivery.

In the 2021 Housing Element, the City relied on AD U production projections to support RHNA capacity, estimating approximately 391 ADUs over the 2021–2029 planning period (or about 50 units annually). These projections were based on observed increases in ADU activity between 2018 and 2021, as well as the anticipated continued impact of recent State legislation and local incentives promoting ADU development.

As part of this amendment, the City no longer relies on projected ADU production to meet RHNA obligations. Instead, ADU production is captured as part of credit towards RHNA reflecting actual permitting and completion reported in the City’s APRs . To assist in reaching the City’s ADU development projections, Costa Mesa has included Program 3E , which explores actions the City will take to promote and incentivize the development of ADUs during the pl anning period. As outlined in the program, these actions may include:
 Coordinating with the County on implementation of a permit-ready ADU program  Waiving specific permitting fees to make ADU development more feasible 422

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-151  Creating an expedited plan check review process to ease the process for homeowners  Explore potential State and Regional funding sources for affordable ADUs Summary of Sites Inventory and RHNA Obligations
As described in this section and in further detail in Appendix B , the City of Costa Mesa has identified adequate sites to accommodate the 2021-2029 RHNA obligation of 11,760 housing units. These candidate housing sites, in combination with the programs stated in Chapter 4, will help to facilitate the development of future housing within the city.

G. Financial Resources
Providing an adequate supply of decent and affordable housing requires funding from various sources, the City has access to the following funding sources.

1. Section 8 Housing Choice Voucher, CDBG and HOME funds The Section 8 Housing Choice Voucher program is a Federal government program to assist very low-income families, the elderly, and the disabled with rent subsid y payments in privately owned rental housing units.

Section 8 participants are able to choose any housing that meets the requirements of the program and are not limited to units located within subsidized housing projects. They typically pay 30 to 40 percent of their income for rent and utilities. The Orange County Housing Authority (OCHA) administers Section 8 Housing Choice vouchers within the City of Costa Mesa. OCHA reports that as of June 30, 2014, a total of 640 vouchers were granted to Costa Mesa households.

Community Development Block Grants (CDBG)
The Community Development Block Grant (CDBG) program provides annual grants on a formula basis to cities to develop viable urban communities by provid ing a suitable living environments and by expanding economic opportunities, principally for low- and mo derate-income persons (up to 80 percent AMI). CDBG funds can be used for a wide array of activities, including:
 Housing rehabilitation;
 Lead-based paint screening and abatement;
 Acquisition of buildings and land;
 Construction or rehabilitation of public facilities and infrastructure, and:
 Public services for low-income households and those with special needs.

In order to receive CDBG funding, the City of Cost a Mesa is required to approve and implement the 2020- 2024 Consolidated Plan. This is a pl anning document that identifies the City’s housing and community needs and outlines a strategy to a ddress these needs utilizing funds from the U.S. Department of Housing and Urban Development (HUD).

HUD also requires the City to prepare a One-Year Acti on Plan for each of the five years covered by the Consolidated Plan. For the 2020-2021 fiscal year the City of Costa Mesa received $1,600,000 in CDBG and HOME funding (including public service grants associated with CDBG) are anticipated to be allocated towards:

HOME Investment Partnership Program (HOME)
The HOME program provides federal funds for the development and rehabilitation of affordable rental and ownership housing for households with incomes not exceeding 80 percent of area median income. The program gives local governments the flexibility to fund a wide range of affordable housing activities through housing partnerships with private industry and non- profit organizations. HOME funds can be used for activities that promote affordable rental housing and homeownership by low-income households.

As with CDBG funding, HOME funds require the City complete a Consolidated Plan and a One-Year Action Plan. The 2020-2024 Consolidated Plan identifies the following objectives for HOME funds:

High Priority Need:
 Housing rehab: $275,000
 Tenant Based Rental Assistance:
$150,000
 Community Housing Development
Organization Reserve: $180,365
 Program Admin: $50,582

2. Opportunities for Energy Conservation
The primary uses of energy in urban areas are for transportation lighting, water heating, and space heating and cooling. The high cost of energy demands that efforts be taken to reduce or minimize the overall level of urban energy consumption. Energy conservation is important in preserving non-renewable fuels to ensure that these resources are available for use by future generations. There are also a number of benefits associated with energy conservation including improved air quality and lower energy costs.

Energy Use and Providers
Southern California Gas Company (SCG) provides natura l gas service for the City. Natural gas is a “fossil fuel” and is a non-renewable resource. Most of the major natural gas transmission pipelines within the City are owned and operated by SCG. SCG has the capacity and resources to deliver gas except in certain situations that are noted in state la w. As development occurs, SCG will continue to extend its service to accommodate development and supply the necessary gas lines. Electricity is provided on an as-needed basis to customers within existing structures in the City.

Southern California Edison Company (SCE) is the distribution provider for electricity in Costa Mesa. SCE services an area of 50,000 square miles with a population over 10 million; Costa Mesa represents less than one percent of the population served by SCE. Currently, SCE has no immediate plans for expansion of infrastructure, as most of the City is built out. However, every year SCE expands and improves existing facilities 424

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-153 according to demand and they have indicated that future growth in Costa Mesa as anticipated in the General Plan is within the parameters of the overall projected load growth which they are planning to meet.

Energy Conservation
The City’s Conservation Element of the General Plan identify and establish goals and policies for preserving and managing natural resources in the City. The element states that solutions to energy problems can be solved through conservation and through the developm ent of alternate energy sources. Energy suppliers are continuously searching for new and expanded sources of conventional fuels such as oil, gas, and coal.

More recently developed fuels, such as nuclear and geothermal, make up a small share of the nation's energy supplies.

The City’s Conservation Element states the City does not operate any local utilities related to energy, however, it partners with and supports energy prov iders to promote sustainabl e practices through local regulations. The Element also reports that while the national consumption of energy has increased by over 50 percent in the last 30 years, the State of California has remained stable due to conservation campaigns by individuals, businesses, utilities companies, and State and local regulations.

Solar energy is the viable alternate energy source for the City of Costa Mesa. As of January 2020, the State of California requires all new single-family and multi-family homes (up to 3 stories high) include a solar photovoltaic (PV) system as a source of electricity. The California Clean Energy Commission determined this mandate increases the cost of sing le-family residences by $8,400, but it saves homeowners and renters about $80 per month on electricity costs. To further promote the swit ch to solar energy, the City of Costa Mesa initiated the Go Green Program which waives permit fees for residential solar installations and electric vehicle charging stations.

The Leadership in Energy and Environmental Design (LEED) certification is a world-wide rating system which reviews and rates buildings, communities, and cities on their energy efficiency and conservation strategies.

A LEED certified building is rated based on a set of points received and may be rated “certified” at the lowest and “Platinum” at the highest. In 2007, the City of Costa Mesa impl emented a Green Building Program aimed at promoting energy efficiency by expediting the permitting process and waive certain fees for LEED certified projects. The City also became th e first California city to require all new Municipal buildings be LEED Gold certified. LEED certified buildings are recognized for providing the following:
 Improved productivity and morale amongst workers, recruitment, and higher retention rates;  Improved indoor environmental quality and air quality;  Minimized energy and water costs during construction and operation;  Minimized waste output;
 Pollution prevention; and
 Low-impact materials that last longer and may be non-toxic, recycled, and sustainably produced.

In February 2021, the City of Costa Mesa became the first city in California to achieve a LEED Gold for Cities and Communities certification.
425

Chapter 3: Housing Constraints, Resources, and Fair Housing 3-154 Lastly, the City also abides to Title 24 standards as mandated by the State. Title 24 establishes energy efficiency standards for residential and nonresidential buildings (new structures and additions) to reduce energy consumption. The standards are updated every three years to achieve greater efficiency and reach for new goals.

Housing Plan
The Housing Plan describes the City of Costa Mesa 2021-2029 policy program. The Housing Plan describes the specific goals, policies, and programs to assist City decision makers to achieve the long -term housing objectives set forth in the Costa Mesa Housing Element. This Plan identifies goals, policies, and programs aimed at providing additional housing opportunities, removing governmental constraints to affordable housing, improving the condition of existing housing, and providing equal housing oppo rtunities for all residents. These goals, policies, and programs further the City’s overall housing policy goal is to Inspire a more diverse, sustainable, and balanced community through implementation of strategies and programs that will result in economic ally and socially diversified housing choices that preserve and enhance the special character of Costa Mesa.

Regional Housing Needs Assessment
The S outhern California Association of Governments (S CAG) has conducted a Regional Housing Needs Assessment (RHNA) to determine the City’s share of the affordable housing needs for the Orange County region. The RHNA quantifies Costa Mesa’s local share housing needs for the region by income category.

Income categories are based on the most current Median Family Income (MFI) for Orange County. The City’s 2021-2029 RHNA growth need is as follows:
• 2,919 units - Very low income (0-50% County MFI)
• 1,794 units - Low income (51-80% of County MFI)
• 2,088 units - Moderate income (81-120% of County MFI) • 4,959 units - Above moderate income (120% or more of County MFI) 11,760 units – Total
A. Guiding Principles
The City of Costa Mesa followed certain “guiding principles” in developing its approach and strategy for accommodating future housing growth. These guiding principles assist with implementation of the housing goals, policies and programs and will aid overall decision making. The guiding principles are rooted in community engagement and local knowledge and input into the planning process. The guiding principles are as follows:
• The City will plan for future housing primarily along major commercial, industrial, and mixed-use corridors within Costa Mesa that are compatible with growth , while preserving established residential neighborhoods.
• Each neighborhood, community, and district within Costa Mesa has its own unique characteristics and needs. Future housing growth will build upon Costa Mesa’s history and complement the diversity and unique characteristics that already exist within each area. • The City will plan for a diverse range of housing forms, types, and densities to address the housing needs of an inclusive and diverse community and provide housing opportunities that meet the needs of all residents, including low-income households, seniors, multi-generational families, larger households, and special needs groups.
428

Chapter 4: Housing Plan 4-2
As identified in Chapter 2, the City will need to address the following findings based on the data presented in this Community Profile:
• The Costa Mesa population is showing aging trends – housing goals should address the needs of seniors who may have less flexible income, need accessibility accommodations, or may seek assisted living options. The City has established Housing Program 2D to address this finding. • Over a quarter of the Costa Mesa population identifies as Hispanic or Latino – housing needs should account for possible cultural needs such as larger or multigenerational housing units. Additionally, housing information should be made available in Spanis h to assist in the location of appropriate housing within the community. The City has established Housing Programs 2E and 4A to address this finding.
• Approximately 47 percent of the Costa Mesa population earn a lower income, indicating that production of and access to affordable housing including affordable rental options and entry level home ownership facilitation should be addressed. The City has established Housing Programs 2B, 4A, 4B, and 4C to address this finding.
• Approximately 48.8 percent of renters and 31.8 percent of homeowners are estimated to spend more than 30 percent of their income on housing, indicating a high housing cost burden overall with a higher proportion of renters compared to owners experiencing overpayment. The City has established Housing Programs 2B, 4A, 4B, and 4C to address this finding. • Based on for sale and rental housing prices, a moderate-income household cannot afford to own a home in Costa Mesa, while lower income households cannot afford to own or rent in Costa Mesa without experiencing overpayment. The City has established Housing Programs 2B, 4A, 4B, and 4C to address this finding.
• The majority of housing units in Costa Mesa were built over 30 years ago – households in older homes may benefit from assistance in renovating their homes and ensuring safe living environments with access to all utilities. The City has established Housing Programs 1A and 1B to address this finding.
• Costa Mesa has a relatively low vacancy rate, indicating high demand for housing and low availability of housing units within the City. The City has established Housing Programs 2B and 3A to address this finding.
• 46.5 percent of Costa Mesa households have at least one of the four identified housing problems, which include:
o Units with physical defects (lacking complete kitchen or bathroom); o Overcrowded conditions (housing units with more than one person per room – excluding bathrooms and kitchens);
o Housing cost burdens, including utilities, exceeding 30 percent of gross income; and o Severe housing cost burdens, including utilities, exceeding 50 percent of gross income.

The City has established Housing Programs 1A, 1B, and 4A to address this finding.

PROGRAM 2B: Affordable Housing Development
The City understands that there may be local procedures or standards that could impact the development of affordable housing. The development process relies on a number of factors working together, including timing, fees and flexibility in design components required of a project. As such, this program aims to inform and incentivize the development community to develop affordable housing.

Objectives:
• Pursue State and regional funding for affordable housing development. • Pursue local partnerships and annually meet with affordable housing organizations to encourage the development of housing affordable to all segments of the population. • Establish development incentives (i.e. deferment of fees, priority processing, modified development standards, etc.) for affordable housing projects that meet objective evaluation criteria similar to the process for density bonus concessions. The City established a streamlined development review for qualifying projects on Housing Element sites and in the MUOD.

Streamlined development review allows for a ministerial approval consistent with applicable provisions of State Law. Residential construction of two or more stories is subject to development review, which is a ministerial planning division review against applicable objective zoning standards of the Citywide Multifamily Residential and Mixed-Use Objective Design Standards.

State Density Bonus Law review has also been modified to Planning Division review authority. • Develop clear instructional materials for achieving incentives and make them publicly available on the City’s website.

Timeframe: Establish incentives and instructional materials by December 2023. Pursue funding and partnership annually. Meet with organizations annually.

PROGRAM 2D: Facilitate Development of Senior Housing Options Senior residents, generally defined as those over 65 years of age, make up approximately 10.7 percent of the population in Costa Mesa and 7.5 percent of all households within the City are seniors living alone. As part of the candidate housing sites analysis, the City has identified one parcel suitable for the specific development of senior housing. In 2025, the City approved entitlements for a 70 -unit senior housing development at th is site. This program aims to coordinate with the project developer to facilitate the development of senior housing on this parcel . Further, the City will continue to seek other potential opportunities to facilitate the development of senior housing across the City.

Objectives:
• Identify potential opportunities for Senior Housing developments within Costa Mesa, including working with developers who specialize in the development of Senior Housing. • Support the development of senior housing on the Senior Center parcel identified as part of the candidate housing site analysis through developer coordination and letters of support for financing, as needed.

Timeframe: Annually meet with senior housing developers to receive feedback, market housing sites adequate for the development of senior housing and pursue other opportunities for senior housing development.

PROGRAM 2E: Encourage Development of Housing Options for Large-Family Households Large households are defined as those consisting of five or more members. In Costa Mesa, approximately 10 percent of all households meet the definition of a large-family household. The majority of large-family households are renter -occupied (62.8 percent) as opposed to owner -occupied (37.2 percent). This is compounded by the fact that single -family detached households, which generally tend to be owner - occupied in Costa Mesa, are more likely to be able to accommodate five or more people while apartment complexes rarely develop units larger than 3 bedrooms.

Objectives:
• Promote and w ork with applicants who propose for -rent residential projects to encourage 4- bedroom units as part of proposed developments.
• Review development standards to determine if any pose an impediment to the development of larger units. If it is found that certain standards present an impediment, the City will adopt amendments to the Zoning Code to alleviate those impediments. In April 2026, the City amended 434

Chapter 4: Housing Plan 4-8
its parking requirements to eliminate standards based on the number of bedrooms, reducing constraints on the development of larger units.

Timeframe: Review development standards for larger units and, if necessary, amend the Zoning Code by Winter 2025. Annually meet with housing developers to encourage the development of larger units.

PROGRAM 2I: Promote State Density Bonus Incentives
Density bonus is an effective incentive to aid in the development of affordable housing units within Costa Mesa through providing concessions to proposed developments that meet specific affordability criteria.

These concessions may take the form of additional residential units permitted beyond the density allowed in the base zoning, a relaxed parking standard, as well as the ability to deviate from development standards.

Currently, the maximum number of concessions a project can receive through density bonus is three. In January 2026, the City received grant funds to support review and recommendations for revisions to the Density Bonus Ordinance.

Objectives:
• Evaluate and update the Density Bonus Ordinance to comply with State Density Bonus Law.

PROGRAM 3B: Fairview Developmental Center – State Property Fairview Developmental Center, owned by the State of California, is a 109-acre property located at 2501 Harbor Boulevard in Costa Mesa. This property historically housed adults with intellectual and developmental disabilities but is closed and has been identified as surplus property by the State . The City has engaged with the State Department of General Services regarding the future use of the property as a master planned residential/mixed -use community with a substantial affordable housing component and other community amenities.
440

Chapter 4: Housing Plan 4-14
The City has been coordinating with the State of California Department of General Services (DGS) for future use of the site. The City is considering various zoning strategies permit the residential densities and development of the acreage identified within the candidate housing sites inventory, while also considering expedited permitting.

On June 26, 2022, Senate Bill No. 188 was approved by the State Assembly, which authorized the State to enter into an agreement with the City of Costa Mesa for the City to develop a specific plan for the Fairview Developmental Center property. The State ap propriated $3.5 Million to the State Department of Development Services for allocation to the City to facilitate disposition of the Fairview Developmental Center property, by amending the general plan of the City and any appropriate planning documents and zoning ordinances, completing any environmental review, and addressing the economic feasibility of future development to be utilized for a mixed-use development, including mixed-income housing. Pursuant to the Senate Bill, the development would include and prioritize affordable h ousing, including at least 200 units of permanent supportive housing, and open space.

Objectives:
• Partner with the State to pursue compatible development on the Fairview Development al Center site consistent with the State’s Site Assessment and the Housing Element’s sites analysis to permit residential development at the identified densities.
• Complete land use and rezoning actions at the Fairview Developmental Center through development of a Specific Plan, and/or other appropriate actions necessary to im plement the Specific Plan by the end of 2026. The Specific Plan will be consistent with the residential dwelling units identified in the sites inventory for the site and will be subject to affordability requirements and development process incentives such as expedited processing including a dedicated staff project manager to promote future projects within the Fairview Developmental Center property to include affordable housing. The Specific Plan will include objective development standards to give clear guidance to future development projects with the intent of reducing the time it takes to entitle and develop projects for residential uses. The City will facilitate parceling and site planning at appropriate sizes as part of the Specific Plan implementation. • DGS opened their application portal in January 2026, for the disposition of the site (available as either for sale or long-term lease) to allow interested developers to s ubmit proposals for State consideration for the selection of a master developer for the redevelopment of the Fairview Developmental Center . The City ’s assigned project manager will facilitate and coordinate the review of future development applications with the master developer for any potential entitlements that may be needed and all applicable building permits. • On October 4, 2022, the City approved an agreement with the State of California to fund planning services relating to the Fairview Development al Center. The agreement stipulates that the State will provide up to $3.5 million in funds to the City to support an up to three -year agreement for a City-led local outreach and land planning effort for the FDC site. The funds will be used for the following land use planning activities: extensive community engagement, technical analysis and infrastructure studies, conceptual land use exhibits and Land Use Alternatives, preparation of a Specific Plan and associated gene ral plan and zoning amendment, preparation of the Environmental Impact Report and associated technical studies pursuant to the California Environmental Quality Act, public hearings and review of the State prepared RFP process for site disposition.

Responsible Agency: City of Costa Mesa/State of California Funding Sources: State and Federal Grant Funds, In Kind PROGRAM 3C: Update the North Costa Mesa Specific Plan
The North Costa Mesa Specific Plan is an existing specific plan located north of the 405 Freeway, containing a mixture of residential, commercial, office, and cultural/arts uses. Development in this area is typically of higher densities/intensities than other areas in Costa Mesa. This area is a key component of the City’s sites strategy for future housing growth.

The City will complete the required zoning code/Specific Plan amendments to update the North Costa Mesa Specific Plan based on the sites analysis to permit residential development at an allowable density up to 90 dwelling units per acre . Through this program, the City will modify development standards to promote residential development at the allowable density. These updates may include amending the boundary of the Specific Plan area as well as revising development standards. The number of housing units able to be developed in these areas is determined by the density. This program modifies densities within the North Costa Mesa Specific Plan to accommodate the assumptions within the Housing Element. As part of this effort, in April 2026, the City approved an amendment to the North Costa Mesa Specific Plan to rezone the Housing Opportunity sites and to meet all by right requirements pursuant to California Gov Code 65583 (h & i). The City will further amend the specific plan to accommodate additional residential and mixed-use development capacity as part of a greater citywide effort to implement Measure K.

Objectives:
• Complete the required zoning code/Specific Plan amendments to update the North Costa Mesa Specific Plan based on the sites analysis to permit residential development at an allowable density of up to 90 dwelling units per acre. As noted in the program, development capacity is determined by density so effectively there are no total unit caps within the North Costa Mesa Specific Plan.

Rezoning has been completed to meet all by right requirements pursuant to California Gov Code 65583(h & i)

PROGRAM 3D: Update the City’s Urban Plans and Overlays
The City has adopted Urban Plans and overlays that apply to specific planning areas and corridors within the City. These plans are intended to encourage compatible development through modified development standards and guidelines specific to a localized area of the City.

The City will complete the required Zoning Code amendments to rescind the existing Urban Plans and update the Overlays based on the sites analysis to permit residential development at the densities identified in the candidate housing sites analysis . These updates may include amending the boundary of the Specific Plan area as well as revising development standards. Densities for residential development are anticipated to differ depending on the surrounding context and are listed in Appendix B.

The City has identified the acreage shown below in and around the identified Urban Plan and Overlay areas to be rezoned. Urban Plan and overlays do not change the base zoning of a parcel, but rather add flexibility in development potential, including uses and densities. There are no caps on residential development within the Urban Plan and Overlay areas.

Objectives:
• Complete the required Zoning Code amendments to update the existing Urban Plans and Overlays based on the candidate housing sites analysis to permit residential development at the identified allowable densities:
o 19 West Urban Plan (50 du/ac) . The City will rescind the 19 West U rban Plan, and consolidate the area into a greater Mixed-Use Overlay District (MUOD). o SoBECA Urban Plan (60 du/ac) . The City will rescind the SoBECA Urban Plan , and consolidate the area into a greater MUOD.
o Mesa West Bluff Urban Plan (40 du/ac) . The City will rescind the Mesa West Bluff Urban Plan , and consolidate the area into a greater MUOD.
o Harbor Mixed-Use Overlay (50 du/ac). The City will rescind the Harbor Mixed-Use Overlay, and consolidate the area into a greater MUOD.

PROGRAM 3E: Promote the Development of Accessory Dwelling Units (ADUs) Costa Mesa has single-family and multi-family residential neighborhoods which create the environment for accessory dwelling units to be built. As discussed in the analysis in Chapter 3, new State Laws, combined with relaxed development standards (such as waiver of parking requirements along with increased educational efforts by the City) have resulted in an increased number of ADUs being permitted and constructed since 2018. In 2023 and 2025, the City approved updates to the ADU ordinance, consistent with State Law.

Additionally, in January 2025, the City launched a pre approved ADU program to offer homeowners an expedited and efficient path to adding ADUs by selecting pre-approved design plans to ensure a streamlined 443

Chapter 4: Housing Plan 4-17
site plan review process. The City anticipates continued growth in ADU development as the concept becomes more common within Southern California. The City will implement programs with the intent of promoting the development of accessory dwelling units within the 6th cycle including the following.

Objectives:
• Review and revise the City’s ADU ordinance as necessary to comply with State Law. (Completed) • Coordinate with the County on implementation of a permit-ready ADU program. • Post a user-friendly FAQ on the City’s website to assist the public. • Offer permitting fee waivers, as funding is available. • Create an expedited plan check review process to ease the process for homeowners. • Research potential State and Regional funding sources for affordable ADUs and make the information found publicly available to homeowners.
• Engage with residential development applicants regarding ADU opportunities that may not have been considered.

PROGRAM 3F: Motel Conversions, Efficiency Units, and Co-living Housing Types Motel conversions to permanent housing are referenced in the Zoning Code but policies and standards have not been updated for many years and may serve as an impediment to conversions. Participants in the City’s community outreach process expressed that these types of units may meet a need for students, young professionals, seniors, or anyone within the community who may desire smaller housing unit options that are more affordable. Additionally, the City’s analysis in Chapter 2 showed that non-family households made up an estimated 40.2 percent of total households within Costa Mesa in 2018. Co-living or flexibility in housing types may present increased housing options at different affordability levels for this large portion of households in Costa Mesa.

In April 2026, the City approved amendments to the Zoning Code to define “efficiency unit” and “single room occupancy unit” to address the need for development types with small unit sizes and shared facilities.

Further, to address the potential housing need that motels may serve, the City approved an amendment to the Motel Ordinance to ensure that all laws are followed related to the displacement and relocation of residents in the event that a motel is converted.

If an appropriate project becomes available, the City will explore opportunities to implement motel conversions through Project Homekey understanding that it is a competitive grant process that does not guarantee funding. The City has received a grant for two projects under project Homekey and has approved a funding commitment of up to $5.85 million for local match funding for these Homekey projects.

Permits have been issued for these projects totaling 126-units. A qualified /experienced City staff member has been assigned to manage these potential program activities. 444

Chapter 4: Housing Plan 4-18
Objectives:

PROGRAM 3G: Address City-wide Vote Requirement in Relation to Housing Element Compliance As it exists upon adoption of the 2021‐2029 Costa Mesa Housing Element, the City’s Municipal Code requires voter approval of certain changes in land use, defined as those projects that amend, change or replace the General Plan, the Zoning Code, a specific plan, or an overlay plan, (collectively, legislative changes) and that involve any one of the foll owing changes: adds 40 or more dwelling units, generates more than 200 additional average daily trips; increases the volume/capacity of an intersection based on specified formulas; changes the intersection capacity utilization or level of service based on specified formulas; adds 10,000 square feet of retail, office or other nonresidential; or, where the proposed project, combined with other projects within 8 years and a half mile of each other, meet the above criteria.

Additionally, voter approval is required for projects that involve one of the above legislative changes and:
changes from public uses to private uses under specified circumstances; land designated as utility right‐of‐ way under specified circumstances; land donated, bequeathed, or otherwise granted to the City; land used or designated for Costa Mesa school property; or land owned, controlled, or managed by the City.

To address this constraint, in November of 2022, the Costa Mesa Voters approved an amendment to the Costa Mesa Zoning Code (Measure K) to revitalize key commercial and industrial corridors by allowing for housing development opportunities. The voter approved initiative provide s flexibility for the City Council to authorize amendments to applicable documents affecting the Measure K sites without the need to receive public voter approval. While the City-wide vote process still exists for those sites not identified by Measure K , this voter initiative creates a clear path to implementing the land use and zoning changes necessary to achieve State‐mandated compliance with the RHNA allocation and State housing requirements.

The City took the following steps to identify and address specific ways in which the City-wide vote process functions as a constraint to housing compliance, the city’s housing goals, and other shared community goals.

Prepare General Plan amendments, rezones, and revisions to existing specific plans, urban plans, and overlays included as program actions necessary to meet the City’s RHNA allocation as identified within the Housing Element. Complete appropriate technical studies and CEQA compliance documents. Obtain City Council approval.

Complete by December 2026

In addition to these actions, beginning in 2022 and in conjunction with the City Attorney’s Office, the City will evaluate and pursue various options to minimize the constraints of a city -wide vote requirement on housing by providing the City Council greater discretion in approving housing and affordable housing projects to comply with all requirements in State Housing Element law without further ballot initiative.

Objective:
• Minimize the constraint of a city-wide vote requirement on creation of housing including affordable housing through the modification of existing City overlays, urban plan areas, and specific plans to rezone candidate housing sites that can accommodate affordable housing and a variety of mixed use/ housing options near jobs and transit. By 2025, initiate a ballot measure, or other alternative option, to provide City Council greater discretion in approving affordable housing and mixed use/ housing options in appropriate locations.

Timeframe: To be completed by Winter 2026.

PROGRAM 3K: Explore Potential Future Housing Opportunities on Church Sites The City did not identify any church properties as housing opportunity sites within the 2021-2029 Housing Element but believes these partnerships with the local faith -based organizations that serve Costa Mesa could be an important component of the overall process of creating more affordable housing in the community. This program is underway and will be completed as part of the City’s REAP 2.0 grant initiative.

The City is conducting stakeholder meetings in June to better understand opportunities and needs related to faith -based sites. City staff will prepare an inform ational handout for faith -based organizations that explains applicable State Law and available housing opportunities on faith-based sites.Objectives:
• Collaborate with members of the faith -based community to discuss housing and the unique opportunities and challenges faced by faith-based organizations when considering creating housing opportunities on church properties with the potential for wrap around services. • Develop materials outlining the development process and make them available on the City’s website.

PROGRAM 3M ADU and JADU Monitoring Program
ADUs and JADUs may be developed in addition to an existing single- or multi-family residential use and can provide a source of affordable housing for family members, students, and other members of the community. As a result of new legislation and an increased effort by the City to promote ADUs, the City has seen an increase in applications in recent years and anticipates growth throughout the planning 448

Chapter 4: Housing Plan 4-22
period, as detailed in Appendix B of this Housing Element. In 202 3, the City launched a new permit application and land management system – the Totally Electronic Self Service Application (TESSA) to help monitor ADU development as well as affordability levels . The City also established a Pre-Approved ADU Program. This program is intended to streamline the ADU review process by allowing homeowners to select from pre -approved ADU plans that meet State and local requirements, thereby reducing review times, costs, and uncertainty for applicant s. The City is currently working with interested architects to review proposed pre -approved ADU plans, and approved plans and vendor information will be made available to the public once finalized.

Objectives:
• Create a monitoring program to track ADU and JADU development and affordability levels throughout the planning period. (Completed)
• As of the 2026 housing element amendment, the City is no longer relying on ADUs to accommodate the RHNA. However, the City has seen strong trends related to ADU development well beyond the projects made in 2021.

Timeframe: Monitoring program (completed)
Responsible Agency: City of Costa Mesa Economic and Development Services Department/Planning Division Funding Sources: In Kind
PROGRAM 3N: Candidate Sites Used in Previous Housing Elements Pursuant to State Housing law, candidate sites identified in this Housing Element to accommodate a portion of the City’s low- and very low-income RHNA that were identified in previously adopted Housing Elements must be rezoned to allow residential use by right at specified densities for housing developments in which at least 20 percent of the units are affordable to lower income households. By right shall mean the jurisdiction may not require a Conditional Use Permit or other discretionary, local -government review or approval that would constitute a “project”, except if the project requires a subdivision ; however, the City may impose objective design review standards on projects.

The City has identified as part of this Housing Element update d vacant and nonvacant sites that were used in previous Housing Elements to meet the current RHNA need. This can be found in Table B -6 in Appendix B.

In April 2026, the City approved an amendment to the Zoning Code to amend an overlay for by right housing for applicable projects on sites used in previous H ousing Elements, consistent with the objectives of this program.

Objectives:
• Place a housing overlay zone over all nonvacant sites included in a prior Housing Element and all vacant sites included in two or more consecutive planning periods that permits by right housing development for projects that meet the requirements of State housing law (Gov Code Section 65583.2(c).

Responsible Agency: City of Costa Mesa Economic and Development Services Department/Housing and Community Development Division
Funding Sources: State and Federal Grants, OC Housing Finance Trust PROGRAM 3Q: Lot Consolidation
The City of Costa Mesa has identified several candidate housing sites that are smaller than half an acre in size. These sites are identified within Table B-6 under the “Potential Consolidation” column of the table.

Assembly Bill 1397 identifies general size requirements for candidate housing sites of greater than half an acre and less than 10 acres in size. The City has only identified sites smaller than half an acre which show the likelihood of redeveloping in conju nction with other parcels which collectively meet the half acre requirement. In April 2026, the City amended the Zoning Code to streamline residential development application processing, establish staff as the final review authority for more application types, removed the parking minimum for residential projects on Housing Element sites, and reduced the parking minimums required for multifamily housing citywide.

(Completed)
Timeframe: Completed March 2026.

Responsible Agency: City of Costa Mesa Economic and Development Services Department/Planning Division Funding Sources: General Fund
PROGRAM 3R: Development of Large Sites
The City of Costa Mesa has identified several candidate housing sites that are larger than 10 acres in size as identified previously in Appendix B. Assembly Bill 1397 identifies general size requirements for candidate housing sites of greater than half an acre and less than 10 acres in size. These sites are:
• Fairview Developmental Center (Addressed separately in Program 3B) • Sakioka Lot 2
• Pacific Arts Plaza (former restaurant and parking lot) With the exception of the Fairview Development al Center which is addressed separately , all of these properties are regulated by the North Costa Mesa Specific Plan and the zoning will be updated per the objectives in Program 3C. Additionally, most of these properties have development agreements which already anticipate the development of housing under existing zoning regulations. These agreements may be modified as necessary to reflect additional housing units and re-zoning as identified by the programs within this housing element. These agreements have been amended in the past so there is precedent for modifying them to adjust to market trends and current development conditions. Therefore, there are no unit caps within the City which would limit the number of units which can be developed on these sites. The sites will be planned to the densities provided within the City’s zoning code as amended by the programs within this housing element.

Furthermore, t he City has engaged each of these property owners multiple times throughout the development of the Housing Element and the anticipated number of units within the candidate sites inventory is based on input received. These assumptions have been reviewed in depth and the City has confirmed that these sites meet all requirements for the candidate sites inventory and they are likely to develop with residential uses within the planning period.

As stated below, the City will evaluate the development status of these sites within three years of the zoning amendments being completed to the North Costa Mesa Specific Plan. If there are not clear indications that the development of residential units is likely to occur within the planning period, the City will review its current RHNA progress and identify additional candidate sites within one year if necessary. In April 2026, the City of Costa Mesa removed several large sites from the Housing Element inventory at the request of the property owners. The City continues to communicate with the property owners of large Housing Element sites.
451

Chapter 4: Housing Plan 4-25
Objectives:
• Continue outreach to property owners through annual meetings. Provide technical assistance, incentives, and strategies as appropriate to facilitate the development of affordable housing, including parceling at appropriate sizes or other tools. • Promote development of large sites at the densities and affordability levels identified within the housing element.
• Promote the potential subdivision of large sites into multiple parcels for future develop ment through technical assistance, incentives, and strategies during the initial development phases and when applications come into the City for the identified parcels.

Timeframe: Completed.

PROGRAM 3S: Review and Revise Findings
The City of Costa Mesa has reviewed the approval findings for the three entitlement processes which are potentially applicable to residential development: Conditional Use Permits, Design Review, and Master Plan. Although no projects have been denied due to not meeting the specific findings noted in Section 3, the City found that some approval findings may be interpreted broadly and could be modified for clarity.

In April 2026, the City approved amendments to the permit review process, removing the design review process and created more clarity and streamlining within existing processes. The application of administrative and streamlined processes has been applied where required and is being further explored for opportunities across a variety of uses.

Objectives:
• Review all approval findings for Conditional Use Permits, Design Review, and Master Plan s and revise findings which are capable of being interpreted broadly, with the goal of improving housing cost, supply, timing of approvals, and approval certainty.

Timeframe: To be completed by December 2026.

PROGRAM 4A: Fair Housing
The City of Costa Mesa participated in the 2020-24 update to the Orange County Analysis of Impediments to Fair Housing Choice , as well as completed an analysis of local factors to fair housing issues in the City within the Housing Element. Through each analysis, the City identified the following fair housing issues:
• Housing Discrimination
• Racial and Ethnic Segregation
• Unfair Lending
• Overcrowding
As part of the AFFH assessments, the City also identified the following factors as contributing to fair housing issues in Costa Mesa:
• Community Opposition
• Lack of Investment in Specific Neighborhoods
• Displacement of Residents Due to Economic Pressures
Pursuant to AB 686, the City will affirmatively further fair housing by taking meaningful actions, in addition to resisting discrimination, that overcomes patterns of segregation and foster inclusive communities free from barriers that restrict access to opportunity based on protected characteristic, as defined by California law. The City will continue current efforts to further fair housing as well as implement the actions identified in the following table to mitigate local contributing factors to fair housing issues in Costa Mesa. 453

Appendix A: Review of Past Performance A-1
Review of Past Performance
The following chart is a review of the City of Costa Mesa ’s housing project and program performance in the 2014 -2021 Planning cycle. It is an evaluation of the 5th cycle’s Policy Program and considers all current and existing programs and projects, as well as the most current effectiveness and appropriateness for the 2021-2029 6th Cycle.

Program Evaluation for Households with Special Needs
The City of Costa Mesa has demonstrated a significant effort in working towards accomplishing many of the objectives set for the programs of the past cycle. During the fifth cycle, the City completed a number of key programs to support housing opportunity and made substantial progress towards many of its programs. The City’s successful programs have been identified as continued for the sixth cycle, due to their success in the fifth cycle.

As a part of analyzing prior programs, the element must provide an explanation of the effectiveness of goals, policies, and r elated actions in meeting the housing needs of special needs populations. The table below provides an overview of the City’s prior program accomplishments; achievements related to special needs populations are summarized below:

Seniors
As shown in Section 2, approximately 11% of the population in Costa Mesa are seniors aged 65 years or older. Throughout the 5th Cycle the City partnered and consulted with a variety of groups to address the needs of persons with specialized needs in the City, includin g: Community SeniorServ, Elwyn California, Council on Aging Orange County. The City’s Action Plan identifies 500 pe rsons assists using $56,180 CDBG funds through Services for Seniors/Frail Elderly. Additionally, a Single Room Occupancy Ordinance was adopted in 1991. since then, three projects were completed and occupied for a total of 247 units; including 91 senior units and 11 SRO units.

On July 21, 2020, the City Council approved an Exclusive Negotiating Agreement (ENA) with Jamboree Housing Corporation in det ermining the feasibility, and potential terms, for the right to acquire a long -term leasehold interest in an approximately 0.90-acre portion of the parking lot at the Senior Center property to develop a senior housing project. The conceptual density study plans envisioned the potential for 60 senior affordable dwelling units at the site. An application for an Urban Master Plan Screening for the proposed project was submitted in November 2021 and staff continues to work with the applicant to bring the project forward for a decision.

468

Appendix A: Review of Past Performance A-2
Persons with Disabilities
As shown in Section 2, approximately 8 percent of the population in Costa Mesa have at least one disability. On November 16, 2021, the City Council directed staff to collaborate with the County of Orange and associated development partners to submit application(s) for the Homekey Program grant funding for the acquisition, rehabilitation and conversion of one or two motel locations proposed for permanent supportive housing. City staff have been working with several existing motel owners of properties that range between approximate ly 40 to 90 units. The proposals will provide direct permanent supportive housing with funding from the City of Costa Mesa, the County and (if award ed) Homekey grant funds from the State. The target population for these units would include at risk or currently homeless individuals and seniors, age 62 and over, and chronic homeless individuals and couples, with a subset of the units for eligible persons that qual ify for Mental Health Services Act (MHSA) programs. Because the City operates the 72 bed Bridge Shelter on Airway Avenue, the Homekey Program could provide a seamless opportunity to stabilize this most vulnerable population where supportive services are provided on site, in the expedited Hom ekey permanent supportive housing model.

In 2020, the owner of Costa Mesa Village was awarded “Section 811” program funds for up to 24 of the 96 affordable units. The Section 811 program is a federal Housing and Urban Development (HUD) program administered by the State’s Housing and Community Developmen t (HCD) that provides subsidies for housing for very-low income persons with disabilities, in this case developmentally disabled persons. As such, as units become vacant through attrition, Section 811 eligible residents are being referred to CMV through the Regional Center of Oran ge County. The referral entity is responsible for providing the supportive services to the Section 811 tenants. Programming and services are individualized based on each person’s needs and provided off-site.

Large Households
Large households are classified as those consisting of five or more members. These households can have difficulty in finding housing options that are adequately sized and affordable. As shown in Section 2, large -family households make up approximately 10% of the total households within Costa Mesa. The City permitted over 950 units across all income levels during the 5 th cycle, many of which were single -family and could accommodate large-family households. The majority of those housing units were market rate and not available at levels affordable to low and very low-income households.

The City has implemented Program 2E in the 2021 -2029 Housing Element to prioritize development of housing options to accommodate large - family households, including outreach to the development community and a review of the current development standards to d etermine if any pose potential impediments to building housing that can accommodate larger households. 469

Appendix A: Review of Past Performance A-3
Farmworkers
As previously discussed, farm workers are not a significant portion of the Costa Mesa community. Their needs are accommodated through housing programs and policies that assist lower-income households in general rather than specialized programs, such as:
• Program HOU 1-6 (rehabilitation loan and grant programs) which provided funding for 7 owner-occupied rehabilitation projects; 4 of which were for extremely-low income households, 1 for very low income, and 2 for low income. • Program HOU 2-5 (OCHA rental assistance), which provided homeless prevention services or transitional housing assistance and services to over 450 individuals
• Program HOU 4-4 (preservation of residential developments for families and individuals with specialized housing needs)

Single-Parent Households:

As shown in Section 2, approximately 7.6 percent of Costa Mesa households are single -parent households, a quarter of which (27 percent) live below the poverty line. Costa Mesa Village (CMV), located at 2450 Newport Boulevard, is a 96 -unit single room occu pancy (SRO) affordable housing development with one manager’s unit for a total of 97 units on site. CMV was originally approved and developed as a two-story Travelodge motel in the mid -1980s. In 1991, a conditional use permit (CUP) was approved to allow th e conversion of the existing motel into a single room occupancy (SRO) affordable housing development. As part of the conversion project, the City through its Redevelopment Agency (Agency) provided financial assistance for land acquisition costs in the form of a $500,000.00 loan in addition to a $1,200,000.00 loan from the Orange County Housing Authority. The Agency entered into several agreements with Costa Mesa Village, Ltd. (original developer and current owner of CMV) including a Regulatory Agreement to ensure that the units were provided as very low-income units at or below 50-percent of the area median income (AMI) in perpetuity. The conversion improvements were completed in 1993 and the loans were fully repaid in 2014. Changes to the CUP and Regulatory Agreement were proposed and require approval by the City Council. The CUP modifications were reviewed by the Planning Commission on January 24, 2022 and were recommended for City Council approval by the Planning Commission. The modifications are scheduled for review and consideration by the City Council on February 1, 2022. In conjunction with the CUP changes, the property owner is also changing to a well-known California affordable housing developer (Century Housing Corporation). Century Housing Corporation is mission -driven to support and develop quality affordable home development and manage and administer 1000s of affordable units throughout the State.

Appendix A: Review of Past Performance A-4
Persons Experiencing Homelessness (Unhoused)
As shown in Section 2, the 2019 Point in Time Count showed 193 total persons experiencing homelessness (sheltered and unsheltered). As of 2018 staff worked on establishing a temporary and permanent homeless shelter that will be housing first modeled and will prov ide housing navigation services. In 2019, the City approved the use of a temporary modular structures at Lighthouse Church for the City’s temporary interim bridge shelter. Later in 2019, the City Council adopted an urgency ordinance relating to Accessory Dwelling Units and Junior Accessory Dwelling Units, to be consistent with state law. In 2020, the City approved a permanent homeless shelter (Costa Mesa Bridge Shelter) to replace the temporary bridge shelter identified in 2019. The shelter opened on March 23, 2021. The City of Costa Mesa partners with Newpo rt Beach to leverage scarce resources to better services the homeless population.

During the 5th Cycle, the City provided homeless prevention services (i.e., rental assistance to prevent eviction or deposit assistance to move into housing and rapid housing) or transitional housing assistance and services to over 450 individuals.

In 2020, Families Forward helped house and bring an end to homelessness for 15 Costa Mesa families (49 adults and children), with 33 Costa Mesa families accessing the Families Forward food pantry and taking another step towards stability. When complete, th e Pomona project will serve as an entry point for families in and near Costa Mesa. Also, on November 17, 2020, the City Council approved a Subrecipient Agreement with Families Forward to establish a Tenant Based Rental Assistance (TBRA) program to assist qualified, very low-income households who are current residents of Costa Mesa (or households with strong community ties to Costa Mesa).

Extremely Low Income Households
As shown in Section 2, there are approximately 6,610 extremely low-income households in Costa Mesa per the 2013-2017 Comprehensive Housing Affordability Strategy (CHAS) data available. Extremely low-income renter households have the highest rate of cost burden at 17.5 percent.

Between 2013 and 2020, the City completed 111 mobile home rehabilitation projects, 52 of which were for individuals or family which qualified as extremely low income. The Housing and Community Development Division provided assistance with the purchase and rehabilitation of rental units by non -profit organizations to operate as affordable to low and very -low-income tenants. Funding was provided for 7 owner -occupied rehabilitation projects; 4 of which were for extremely-low income households, 1 for very low income, and 2 for low income.

In 2020, Families Forward helped house and bring an end to homelessness for 15 Costa Mesa families (49 adults and children), with 33 Costa Mesa families accessing the Families Forward food pantry and taking another step towards stability. When complete, th e Pomona project will serve as 471

Appendix B: Sites Analysis B-1
A. Sites Analysis Overview
The Housing Element is required to identify housing sites by income category to meet the City’s RHNA Allocation. The sites identified within the Housing Element represent the City of Costa Mesa’s ability to plan for housing at the designated income levels within the 6th housing cycle planning period (2021-2029).

As described in this appendix, the realistic developm ent capacity for each site was reduced to 80% of maximum allowable density while some sites included additional deductions based on the site location and other known development factors including land use controls, site improvement requirements, infrastructure access and property owner input. Where possible, property owners were consulted to help the City better understand potential future housing growth on candidate housing sites within the City.

This appendix contains Table B-8, which identifies each site within Co sta Mesa’s site’s inventory. The sites are identified by assessor parcel number (APN) as well as a unique identifier used to track sites within the inventory. Additionally, the following information is provided for each parcel:
 Address
 Ownership
 Zoning (including Specific Plans, and Overlays, if applicable)  Size (Net developable acres removing known development constraints)  Density
 Vacancy status
 Previous Housing Element identification
 Potential Development Capacity (Dwelling Units) by income category  Description of existing use

2026 Housing Element Amendment – Overview of Changes to the Sites Analysis

As part of the 2026 Housing Element Amendment, the City implemented several key updates to strengthen the sites inventory and ensure compliance with State law:

1. Refined RHNA Approach:
a. The revised approach to address the RHNA relies on verified production credits toward RHNA based on the Annual Progress Report (APR); and;
b. Sites identified in the Housing Element sites inventory may also include specific projects with approved or pending applications. Sites with proj ects that have active applications are being counted as sites and are subject to all the rezoning requirements. c. Lastly, the City is no longer relying on Accessory Dwelling Unit (ADU) projections to satisfy the RHNA.

2. Revised Realistic Capacity Assumptions:

The 2021 Housing Element submittal assumed development at approximately 90 percent of maximum allowable density across most sites. As part of the 2026 amendment, the City has revised its methodology to reflect more conservative assumptions. For most sites, capacity is now calculated at 80 percent of the maximum allowable density (i.e., a 20 percent reduction from the maximum).

Additional site-specific reductions have been applied where physical, regulatory, or market constraints warrant further adjustments.

3. Removal and Replacement of Sites:

During implementation of required rezonings to accommodate RHNA, the City received requests from property owners to remove their sites from the inventory. In response, in March 2026, the City removed the sites, conducted a no-net loss analysis and began the process of identifying replacement sites to maintain adequate capacity. This process continued as part of the Housing Element Amendment and public review period, during which the City continued to evaluate and, where appropriate, honor property owner requests to remove or add sites. a. On August 12, 2026, as part of the revised Housing Element submitted to HCD in July 2026, the City was notified by two property owners requesting the removal of three Housing Element sites. Specifically, Sites 81 (1751 Placentia Avenue) and 79 (1791 Placentia Avenue), which together accounted for 286 units in the Mesa West Bluffs area, were removed from the sites inventory, along with Site 164 (1491 Baker Street), which accounted for 50 units in the Harbor Boulevard corridor.
b. On August 19, 2026, following the City's Planning Commission hearing, the City received a request from a property owner to remove tw o Housing Element sites: Site 49 (3539 Howard Way) and Site 80 (1650 Sunflower Avenue) which together accounted for 694 units in the North Costa Mesa area. The City has honored this request and removed both sites from the sites inventory.
c. On August 25, 2026, the City received a request from the property owner of an existing Housing Element site at 1485 Dale Way (APN 418-102-10) to add the adjoining APN 418-102-11 to the sites inventory to more accurately reflect the full extent of the property. The City honored the request and incorporated APN 418-102-11 into the broader 1485 Dale Way Housing Element site, identified as Site 180.

The amended Housing Element reflects replacing several previously identified sites with a broader and more diverse pool of 96 sites. The removed sites were generally larger (ranging from 0.19 to 30 acres) and located north of I-405 or along Harbor Boulevard. The existing uses on the removed sites included a mix of parking, office, and institutional uses, some of which had constraints such as long-term non- residential leases.

Appendix B: Sites Analysis B-4
The replacement sites generally share a similar size to the sites that we re removed (ranging from 0.13 to 15 acres, with an average size of approximately 1.44 acres) and are distributed more evenly throughout the City including along mixed-use corridors. The updated inventory expands into additional areas, thereby improving geographic equity and supporting Affirmatively Furthering Fair Housing (AFFH) objectives.

From a density perspective, the prior inventory primarily relied on higher-density sites, including 24 sites at 90 dwelling units per acre (du/ac) and the rema ining sites ranging from 30-60 du/ac. The revised inventory maintains a subset of high-density sites ( 24 at 90 du/ac) but introduces a broader range of densities, with the remaining sites generally ranging from 30 to 60 du/ac. This shift supports a more flexible and realistic development pattern, distributing sites more broadly across the City.

The updated sites inventory results in an overall increase in realistic un it capacity, from 6,043 units in the previous inventory to 6,996 units under the revise d assumptions. Finally, the replacement sites are characterized primarily by underutilized commercial, re tail, office, and storage uses that exhibit strong redevelopment potential, in contrast to several prior sites that involved more complex constraints. Overall, the revised inventory improves feasibility, distribution, and alignment with State housing policy objectives.

Summary of RHNA Status and Sites Inventory
The City’s 2021-2029 RHNA need by income category an d summary of the sites id entified to meet that need is provided in Table B-2. The analysis within this appendix demonstrates that the City of Costa Mesa has the capacity to meet and exceed the 2021-2029 RHNA allocation through a variety of methods, including:
 Identification of development capacity on sites that have been rezoned to permit development of residential uses at or above 30 dwelling units per acre  Credit towards the RHNA

1. Credit Towards RHNA

As shown in Table B-3, the City of Costa Mesa has approved several residential development projects that have contributed to meeting the RHNA since the start of the 6th Cycle planning period. For jurisdictions within the Southern California Association of Governme nts (SCAG) region, RHNA credit may be applied to units that received building permits on or after June 30, 2021, consistent with HCD guidance.

The City of Costa Mesa tracks progress toward its 6th Cycle RHNA consistent with California Department of Housing and Community Development (HCD) Annual Progress Report (APR) requirements.

Credit toward RHNA reflected in Table B-2 is based solely on residential units for which building permits have been issued during the planning period. As defi ned by HCD, permitted units represent the official metric for demonstrating progress toward RHNA. Credit includes only units that have received building permits. Credit excludes projects that are either in the application phase or entitled but have not yet received building permits. A project-level breakdown of the 643 permitted units, including project address, affordability level, and affordability mechanism for each project, is provided in Table B-9.

Based on the City’s 2025 APR, Costa Mesa has issued building permits for 643 units for the 6th cycle planning period. These units represent the City’s cumulative credited progress toward its RHNA obligation for the 6th Cycle planning period.

Demonstrating Affordability

For units credited toward the lower-income RHNA categories (very low- an d low-income), the City documents affordability consistent with HCD’s APR requirements.

 Deed-Restricted Units: For deed-restricted units, affordability was determined based on affordable housing regulatory agreements and covenants.
 Non-Deed-Restricted Units: For non-deed-restricted units counted toward lower-income RHNA categories, affordability was determined using one of two methods depending on the project’s stage of completion at the time of reporting.
o Building permit issued: For non-deed-restricted units where a building permit has been issued but construction is not yet complete and was counted toward lower-income RHNA categories, affordability was determined usin g a methodology consistent with the unit's year of permit submittal. For ADU applicatio ns submitted to the City in 2023 or earlier, affordability was based on the SCAG Regional ADU Affordability Analysis. For ADU applications submitted in 2024, the City distributed a surv ey to ADU property owners requesting their intended monthly rental price and used the survey results to determine the affordability level of each 2024 application. Beginning with applications submitted in 2025, applicants are required to complete a questionnaire disclosing the anticipated monthly rent for the unit at the time of application; the City then applies HCD's affordability calculator, based on the unit's bedroom co unt and anticipated rent, to determine the applicable income category. This questionnaire process has since been incorporated directly into the City's online permitting system.
o Certificate of Occupancy: For non-deed restricted units where a Certificate of Occupancy has been issued, affordability was verified based on actual reported rents or sales prices provided by the applicant.

ADU Rental Survey:

For ADU permits submitted to the Ci ty in 2024, affordability determinat ions were based on results of a survey distributed to ADU owners regarding intended re ntal pricing. Survey results indicated that studio units rented at levels affordable to low-income households, one-bedroom units at levels affordable to very low-income households, two-bedroom units at levels affordable to moderate-income households, and three-bedroom units at levels affordable to above moderate-income households. These results were applied to determine the affordability level of 2024 ADU applications based on unit bedroom count.

The City's progression from a region-wide affordability assumption to project-specific, unit-level verification reflects both improved local data collection and HCD's current guidance requiring an affordability methodology no more than two years old at the time of reporting. The affordability mechanism applied to each project is identified in Table B-9.

Project Status:
492

Appendix B: Sites Analysis B-7

The City's approach to crediting units toward its RHNA progress relies on building permits issued, consistent with HCD's own methodology for tracking Housing Element implementation. While a housing development may receive entitlements well in advance of construction, entitlement alone does not reliably indicate that a project will be built within the pl anning period. The issuance of a build ing permit reflects a substantially firmer commitment to construction, as it follows a de veloper's investment in final design, plan check, and permit fees, and initiates the statutory clock for commencing work.

By anchoring its RHNA credit to permitted units rather than entitled units, the City has applied a conservative and defensible standard: the 643 units represent housing for which construction activity has been formally authorized to proceed, not merely approved at the discretion stage. This approach avoids overstating progress based on projects that remain speculative and provides HCD with a more reliable indicator of the City's actual production trajectory during the current planning period.

Conclusion

Consistent with HCD guidance, Cost a Mesa’s RHNA progress is measur ed using building permits issued, rather than earlier development milestones such as applications or entitlements. As of the 2025 reporting year, the City has credited 643 units toward its RHNA based on cumulative permitting activity during the 6th Cycle planning period. This demonstrates continued advancement toward meeting the City’s housing obligations through projects that have reached the construction-ready stage. Lastly, the City's sites inventory identifies additional adequate sites with capacity to accommodate the City's remaining RHNA obligation across all income categories, independent of the units addressed in this analysis. This additional capacity provides the City with a reasonable buffer to ensure that the City can accommodate its share of the regional housing need throughout the remainder of the planning period, consistent with Government Code Section 65583.2.

2. Selection of Sites - Redevelopment of Non-Vacant Sites for Residential Uses

The City of Costa Mesa has identi fied sites with sufficient capaci ty to accommodate its 2021–2029 RHNA.

In total, 169 parcels have been identified across a range of zones, specific plan areas and overlay districts.

Rezoning Status: As of April 2026, the City completed the required rezoning of all Housing Element sites at the densities specified in Table B-8 to permit residential development, as reflected in Resolution No. 2026- 11, 2026-12. in compliance with Go vernment Code § [65583 and 65583.2 (c)]. Accord ingly, Program 3C (Update the North Costa Mesa Specific Plan), Program 3D (Update the City’s Urban Plans and Overlays) and Program 3N (Candidate Sites Used in Pervious Housing Elements) have been completed.

A. Overview
All identified sites have been evaluated to determine the extent to which on-site uses are likely to redevelop within the planning period. The analysis found th at a number of existing uses (identified in Table B-8) are either permanently closed or available for lease. Many of the uses are in multi-tenant commercial centers with one ownership and most show little to no evidence of recent investment or redevelopment.

When assuming the potential for low/very low-income development on non-vacant parcels, state law requires that the City analyzes the following:
 Analysis of leases where possible, that would prevent redevelopment of the site,  The extent to which existing uses may constitute an impediment to the future residential development within the planning period,
 Record of converting existing uses to higher density residential uses,  Current market demand for the existing use,
 Development trends and market conditions, and
 Regulatory or other incentives to encourage redevelopment.

Lease Analysis
Existing lease agreements on infill and non-vacant properties present a potential impediment to residential development within the planning period. State law requires the City to consider lease terms in evaluating the use of non-vacant sites; however the City d oes not have access to lease agreements or other contractual agreements amongst parties because they are private documents. Therefore, the City has conducted an analysis to identify sites that show ch aracteristics indicating they are likely to redevelop within the planning period, including past performance, an on-the ground existing use analysis and a market analysis to understand cost of land, construction, and development trends in Costa Mesa.

To identify sites with existing uses that have the potential to redevelop into housing or that the existing use will not be an impediment to additional redevelopment, the City developed objective redevelopment criteria based on characteristics observed in sites that have successfully redeveloped into housing during 495

Appendix B: Sites Analysis B-10
the current and prior planning cycles. After applying these criteria and confirming suitability, the City conducted (and is continuing to conduct) outreach to property owners, developers, and the broader community. Based on feedback from this outreach, additional refinements were made, including the removal and addition of sites to ensure a realistic and achievable sites inventory. Where the City received explicit property owner requests to include a site or documented developer interest, this information is noted alongside the respective site in the inventory. The analysis also notes where the City received an interest letter from a developer or property owner.

B. Application of Objective Threshold Criteria:

As a first step in identifying sites to accommodate the RHNA, the City established threshold redevelopment criteria to guide site selection. The threshold criteria are based on characteristics observed in prior Housing Element sites that successfully redeveloped into residential uses. The criteria are as follows:
 Existing uses fall within the development classifications (typologies) identified in the section below as having demonstrated redevelopment potential in the City; and  The site has a utilization rate (“percent occupied”) of 50% or less, with the exception of two sites.

To determine utilization rate, the City evaluated the relative intensity of existing development on each site by comparing existing building square footage to the maximum development permitted under the applicable floor area ratio (FAR). This calculation ex pressed as “% Occupied” indicates the extent to which each site is currently utilized. Sites with lower utilization rates are considered more likely to redevelop because existing improvements occupy a limited portion of the site’s total development capacity, indicating that the current use is not a significant impediment to redevelopment and may be accommodated or replaced as part of future development.

All Housing Element sites meet the threshold criteria described above except for sites listed in Table B-4. 2026 Housing Element Amendment:

To offset the removal of several si tes in March 2026, the City added 94 sites as part of the second 2026 Housing Element Amendment. For these additional site s, the City conducted a detailed screening process to ensure that replacement sites exhibit strong redevelopment potential. All new sites added as part of this amendment were required to meet the following threshold criteria:
 Utilization rate of less than 60%:
o While the screening threshold was set at 60%, most sites are well below this level. Of the 94 new sites:
 36 sites have utilization rates between 0–30%
 31 sites fall between 31–50%
 11 sites fall between 51–59%
 Improvement-to-land value (ILV) ratio of less than 1.0 o Of the 94 new sites:
 Approximately 57 (61%) have an ILV ratio of less than 0.5  26 sites have an ILV between 0.5 and 1.0
 9 sites have an ILV greater than 1.0
 Building age greater than 40 years
496

Appendix B: Sites Analysis B-11
In addition, as part of the 2026 amendment process, the City conducted targeted outreach to property owners and the broader community. Property owners were notified of the potential inclusion of their properties in the Housing Element sites inventory, and the City held a public workshop to solicit input and confirm the appropriateness of the proposed sites. Feedback from this outreach informed final site selection and refinement.

All new sites added through the 2026 amendment meet th e threshold criteria desc ribed above, with the exception of the sites identified in Table B-4. Based on the combination of low utilization, low improvement- to-land value ratios, older building stock, and consideration of AFFH factors—along with input received through outreach—these sites are considered suitable and likely to redevelop with residential or mixed- use development during the 6th Cycle planning period. The low level of existing site utilization indicates that current uses do not fully occupy the sites’ development capacity and are therefore unlikely to present a significant impediment to redevelopment.

Sites Included Based on Additional Redevelopment Evidence:

As noted above, the City initially screened sites using objective threshold criteria, including degree of underutilization, building age, and improvement-to-land value. However, certain sites were retained or added to the inventory based on a dditional site-specific evidence demonstrating that redevelopment during the planning period is realistic.

Table B-4 includes a separate analysis of sites that may not meet every objective screening threshold; however, the City determined that other factors support their inclusion in the sites inventory. This section identifies those sites and describes the site-specific information used to substantiate their redevelopment potential.

C. Development Classifications (Typologies)
As part of the housing sites analysis, the City evalua ted recent residential projec ts that have redeveloped within non-residentially zoned areas. The zoning, use prior to redevelopment, and a brief project analysis of the approved development plan, are shown in Table B-5. The analysis showed that prior uses on these redeveloped sites were similar in nature to existing uses on many sites identified in the sites inventory in Table B-8. Based on the information provided in Table B-5, the City created a classification system for sites with characteristics that are applicable to the candidate sites inventory. The intent of this classification system is to draw parallels from past development, staff knowledge, and trends in development to the potential future development of the candidate housing sites identified. These cla ssifications are based in real past development that has occurred within the City. While some comparisons may not be an exact match for the sites identified, they show a strong correlation with the understanding that every parcel is unique in terms of site characteristics, existing use, ownership, and other factors which can affect future development. The development classes are generally defined as:
 Development Class A: Uses on these sites prior to redevelopment included either light industrial such as manufacturing, assembly, processing, packaging, or storage of products takes place or office type uses. These are areas that previously served commercial or office businesses and have redeveloped throughout the city based on property owner interest and market trends. This also includes uses within the North Costa Mesa and SoBECA areas.  Development Class B: Uses on these sites prior to redeve lopment included self-storage, vehicle storage, and industrial uses. Many of these site s are located within the Mesa West or 19 West areas which covers a large portion of the industrial areas south of I-405.  Development Class C: Uses on these sites prior to redevelopment included primarily commercial uses including gas stations and underutilized surface parking lots along Harbor Boulevard, Newport Boulevard and other major commercial corridors. These projects are typically in a mixed-use setting, whether within the same development or directly adjacent. Many of these sites are within the Newport Boulevard Specific Plan area.
 Development Class D: These sites are potential motel conversions within the City. The City is continuing to pursue Project Homekey funds and other resources to encourage the redevelopment of motels in coordination with property owners and service providers.

D. Field Survey Assessment
In addition to applying objective screening criteria (ILV, building age and utilization) and reviewing existing uses to meet development classifications, City staff, in coordination with the Economic Development 504

Division, conducted a field-based survey and site reconnaissance to further evaluate redevelopment potential.

This effort included on-the-ground observation of site conditions to identify vacancies, underutilized properties, aging structures, and broader patterns of disinvestment at the block and corridor level. The field survey supplemented the quantitative analysis (e .g., utilization and ILV) by providing real-world context regarding site activity, tenant occupancy, and overall economic viability. Observations from this effort informed the identification and refinement of sites included in the Housing Element inventory.

E. Community Input on Sites Selection
The City initially identified sites based on objective criteria, including improvement-to-land value (ILV), building age, and degree of utiliz ation, and then evaluated them for consistency with established development typologies. Throughout this process, the City also incorporated community input, which played an important role in informing site identification and selection.

As part of the 2021 housing elemen t update, the City had conducted mu ltiple public outreach meetings, including district specific meetings where community members gave input on areas of importance within their district. This information was collected as notes on maps of each district and can be found in Appendix C. Community members also provided feedback on potential housing development types and focus areas on the online community survey. Additionally, draft versions of the sites inventory were discussed at both Planning Commission and City Council study sessions, with decision makers providing input and community members able to make public comments.

Lastly, the City held discussions with major property owners within the City to better understand their long- range plans for development of the properties under th eir ownership. The City used these discussions to more accurately determine potential unit yield and affordability assumptions for some of the identified candidate housing sites. Additional information is provided for specific properties in Table B-8. 2026 Housing Element Amendment:

As part of the inclusion of additional sites in this 2026 Housing Element Amendment, the City undertook a comprehensive and proactive outreach and engagement process to ensure transparency and meaningful community participation. The City formally notified all property owners of sites under consideration for inclusion in the updated inventory. Property owners we re invited to participate in the review process and to provide input regarding site suitability, development feasibility, and long-term plans. The City also held two dedicated stakeholder meetings and workshops focused specifically on the candidate sites, allowing for more in-depth discussion of site-specific conditions, constraints, and opportunities.

Where the City received explicit property owner requests to include a site or documented developer interest, this information is noted alongside the respective site in the inventory. 2026 Housing Element Rezone:

In addition to property owner notification, the City conducted targeted outreach throughout the rezoning process, including public workshops and informational meetings designed to inform both affected 505

Appendix B: Sites Analysis B-20
stakeholders and the broader community. These workshops provided an opportunity for participants to ask questions, express concerns, and offer feedback on proposed zoning changes and development assumptions. Through this expanded outreach effort , the City was able to further the sites inventory effectively incorporating community and stakeholder feedback to ensure that the rezoning program and 2026 housing element amendment reflect both commu nity priorities, and realistic development conditions.

F. Experience Developing Non-Vacant Sites for Residential Uses (Development Trends)

The City has also conducted a parcel specific analysis of existing uses for each of the identified sites. This analysis of existing uses, including indicators of a likelihood that the existing use will redevelop within the next eight years, are provided in Table B-8. This analysis is based on information readily available to the City and research that can be found through online research. The City does not always have access to private lease information but has included informatio n that property owners have shared regarding individual sites.

Table B-5 summarizes recent, approved, entitled, and constr ucted residential and mixed-use projects in Costa Mesa to demonstrate local redevelopment pa tterns and the City’s experience converting underutilized commercial, industrial, motel/hotel, office, and vacant sites into housing. The table identifies each project’s location, acreage, unit count, density, zoning, prior use, development classification, Tax Credit Allocation Committee (TCAC)/HCD resource area, and relationship to similar sites included in the sites inventory. Together, these examples show that residential development has occurred across multiple areas of the City, including North Costa Mesa, along Newport Boulevard, Harbor Boulevard, and within the Mesa West Bluffs and 19 West Sub- Areas. Many projects have been built or approved on sites with characteristics similar to those identified in the sites inventory.

This table is intended to support the City’s realistic capacity assumptions by showing that nonvacant and underutilized sites in Costa Mesa have a demonstrated pattern of redeveloping with housing, including affordable housing, senior housing, live/work units, mixed-use projects, and adaptive reuse projects. The examples also help illustrate the types of existing uses that may transition to residential development during the planning period, including light industrial buildings, warehouses, auto-related uses, and motels. 506

Appendix B: Sites Analysis B-25

Additional Redevelopment Information
In addition to the: 1) application of objective redevelopment criteria (including building age, site utilization, and improvement-to-land value ratios), 2) the analysis of existing uses based on development classifications, 3) field survey assessments conducted by City staff, 4) and the consideration of community input, 5) the City also conducted further qualitative and market-informed analysis to evaluate the realistic development potential of candidate sites included in the 2026 Housing Element Amendment. This analysis considered broader redevelopment trends within coastal and high-resource areas.

Overall trends and data indicated that many candidate sites are currently occupied by older building stock with limited reinvestment, lower-intensity commercial uses, or transitional uses that are increasingly considered underutilized relative to their location and zoning potential.

The analysis also found that broader geographic patt erns, including entire blocks characterized by aging building stock and fragmented, low intensity uses. These areas are especially well-positioned for consolidation and redevelopment, particularly where parcel configurations allow for lot aggregation and more efficient site planning.

Location-specific factors further reinforce redevelopment potential. Many of the identified sites are located within designated High or Very High Resource Areas, where access to amenities, employment, and transit significantly increases market demand for housing. In these areas, the underlying land value is already substantial, and the introduction of higher allo wable residential densities amplifies redevelopment feasibility.

As part of the 2026 amendm ent, the City evaluated th e implications of proposed rezoning on land value and development viability. For example, along the Newport Boulevard corridor, allowable densities are proposed to increase from approximately 17 dwelling units per acre to 30 dwelling units per acre. This
increase in development capacity is expected to subs tantially enhance land value, improving the financial feasibility of redevelopment projects and making resi dential uses more competitive relative to existing commercial uses. While precise value increases vary by site, the upzoning establishes a clear economic incentive for property owners to transition to higher-density residential or mixed-use development over time.

Housing Market Analysis
Recent market indicators continue to show strong housing demand and sustained affordability pressures in Costa Mesa and Orange County. According to the California Association of Realtors’ April 2026 Sales and Price Report
4, the median sold price for an existing sing le-family home in Orange County was $1,470,000 in April 2026, up 3.7 percent from $1,417,450 in Apri l 2025. This also represents an increase of approximately 31 percent from the $1,120,000 Orange County median home price cited in the prior 2021

4 California Association of Realtors, “April Home Sales and Price Report,” May 19, 2026, accessed May 20, 2026, https://www.car.org/aboutus/mediacenter/newsreleases/2026releases/april2026sales. 511

Appendix B: Sites Analysis B-26
analysis. C.A.R. also reported that, statewide, the median time on market was 21 days and the statewide sales-price-to-list-price ratio was 100.0 percent, indicating continued competition for available homes.

Orange County market data similarly reflec ts continued demand. As of March 2026, Redfin 5 reported that Orange County homes sold for a median price of $1,260,000, up 4.9 percent year-over-year, with homes selling after a median of 36 days on the market. The countywide sale-to-list price ratio was 99.7 percent, and approximately 36.6 percent of homes sold above list price.

Current new-construction indicators also point to high-cost housing conditions. Realtor.com reported that new construction homes for sale in Costa Mesa had a median listing price of approximately $1,532,000 and spent an average of 48 days on the market, with only a limited number of new construction listings available. Together, these indicators demonstrate that Costa Mesa and the broader Orange County market remain high-cost, competitive housing markets, supporting the continued need for additional housing production and a broader range of housing opportunities.

G. Conclusion
The City concludes that it has applied a robust and evidence-based methodology to identify sites with a strong likelihood of redevelopment during the planni ng period, where existing uses will not pose a significant impediment to residential development. This conclusion is supported by a multi-layered analysis that incorporates development trends, local market conditions, and demonstrated redevelopment patterns.

The City first applied a set of objective criteria to evaluate candidate sites. These criteria included improvement-to-land value (ILV) ratios, building age, and the degree to which a site is currently utilized.

Together, these metrics help identify underperforming or economically underutilized properties that are more likely to transition to higher-value residential or mixed-use projects. In addition, the City applied its development classification system, which categorizes exis ting uses based on their historical propensity to redevelop into housing. This system is grounded in local precedent and reflects uses that have demonstrably transitioned to residential development in prior planning cycles.

To further validate these findings, the City conducted field survey work to ground-truth site conditions and assess neighborhood-level trends. This on-the-ground analysis provided additional insight into factors such as property maintenance, vacancy characteristics, surrounding land uses, and broader market dynamics.

The City also incorporated community input, whic h helped inform local context and identify areas experiencing change or redevelopment pressure.

The selected criteria and thresholds are directly supported by empirical evidence documented in Table B- 8 which summarizes recent residential development projects in the City. Notably, many of these projects redeveloped from sites with similar or even less favorable characteristics than those included in the current inventory. In this regard, the City’s thresholds can be considered conservative.

5 Redfin, “Orange County, CA Housing Market: House Prices & Trends,” accessed May 20, 2026, https://www.redfin.com/county/332/CA/Orange-County/housing-market. 512

Appendix B: Sites Analysis B-27
For sites that did not meet all objective criteria, the Ci ty provided additional justification, as documented in Table B-4. These sites are supported by supplemental in formation demonstrating their redevelopment potential, such as strong market indicators, strategic location, or alignment with specific plan areas.

Furthermore, the examples included in Table B-5 illustrate that residential development has occurred on sites beyond the established thresholds, reinforcing the conclusion that the inventory is realistic and achievable.

Overall, the methodology ensures that the identified sites are both market-feasible and that the existing uses will not be an impediment to additional development.

3. Development of Small Site Parcels
The City of Costa Mesa has identified a total of 44 hous ing sites that are smaller than half an acre in size.

Assembly Bill 1397 identifies general size requirements for candidate housing sites of greater than half an acre and less than 10 acres in size. The City has only identified sites smaller than half an acre which show the likelihood of redeveloping in conjunction with other parcels which collectively meet the half acre requirement. The likelihood of redevelopment wa s based primarily on common ownership amongst adjacent parcels which share a property line. In most instances, these parcels are currently developed as a single use and it is reasonable to anticipate that the collection of parcels will redevelop as one new development to maximize efficiency an d design of the new use. Candidate sites less than half an acre in size represent a small portion of the City’s overall RHNA need. A total of 45 parcels comprise the potential for 436 units, which is 3.71% percent of the City’s total RHNA need. 2026 Housing Element Amendment: The potential candidate sites which are anticipated to be consolidated into a single development are identified within Table B-8.

The City has identified a total of 45 parcels that are less than 0.5 acres. Sp ecifically, the 2026 Housing Element Amendment includes 39 new parcels that are smaller than 0.5 acres and collectively accommodate 148 lower-income units, 69 moderate-income units, and 219 above moderate-income units.

The inclusion of these smaller sites is supported by the same redevelopment criteria described in the sections above. These sites were not added based on parcel size alone; rather, they exhibit characteristics that support a reasonable likelihood of redevelopment during the planning period, including underutilized site conditions, existing low-intensity commercial or industrial uses, surface parking areas, location within adopted urban plan or mixed-use areas, proximity to similar redevelopment activity, and/or demonstrated property owner or developer interest.

In addition, 4 of the 45 parcels were added based directly on property owner requests to include the sites in the Housing Element inventory. Another 3 of the 45 parcels were added because they are associated with active development applications and/or have received land use entitlements. These factors provide additional evidence that the identified sites are realistic candidates for residential or mixed-use redevelopment during the planning period.

Some of the sites smaller than 0.5 acres are individual parcels that may be developed in coordination with adjacent parcels, shared parking areas, or larger development sites. Where applicable, the City has identified potential candidate sites that are anticipated to be consolidated or developed as part of a larger 513

SoBECA 0.27 These parcels are occupied by warehouse and light industrial uses within the SoBECA Urban Plan area. The SoBECA Urban Plan focuses on residential as a mixed-use component and promoting the development of residential
in addition to the existing commercial anchors in the Mall and the Camp. The City has established Program 3D to
update the Urban Plans within the City to focus more
heavily on residential uses at the identified densities.

As identified in Table B-5, the City developed Baker Block on industrial parcels which previously occupied similar light industrial uses in a largely industrial corridor approximately one-third of a mile from the SoBECA area. These uses have similar historical context and assumptions have been tied to this project and others as examples of redeveloping
these types of uses for residential within industrial areas. 41817102 752 Saint

development agreement and is currently planned for
residential development. The City has actively worked with the property owner throughout the 6
th Cycle Housing
Element update process to identify an appropriate number of residential units to allocate towards the site. The property owner has indicated they intend to develop
residential uses on the Home Ranch site and they are
permitted to alter their development agreement or
develop outside of it, meanin g there are no unit caps in place.

While this individual parcel is less than half an acre, it is in common ownership with the larger Home Ranch site which
exceeds the half acre standard. This parcel is currently vacant.

Additionally, Policy LU-2.10 of the City of Costa Mesa’s Land Use Element within the General Plan promotes lot consolidation of residential properties. While the sites identified in the table above are commercial in nature, the intent of the policy remains effective in consolidating smaller parcels towards the creation of a larger residential development.

Small Sites (Under 0.5 Acre) – Realistic Capacity and Lot Consolidation Analysis Consistent with Government Code Section 65583.2, the City has evalua ted whether sites under 0.5 acre included in the sites inventory are adequate to accommodate their assigned realistic capacity. The sites inventory includes 46 individual parcels under 0.5 acre, representing 436 units of realistic capacity. Of these, 44 parcels (406 units) rely on lot consolidation with one or more adjacent parcels, reflecting the pattern of small-lot assemblage that has occurred and continues to occur along the City’s commercial corridors; these 44 parcels consolidate into 18 distinct development sites, summarized in the table below.

The remaining 2 parcels (30 units) are evaluated on a standalone basis and ar e addressed following the summary table.

Lot consolidation is not a speculative assumption in Costa Mesa: an entitled project at 1711 and 1719 Pomona Avenue (Group I below) demonstrates this exact pattern, where two contiguous, commonly- owned parcels under 0.25 acre each were assembled into a single entitled live/work development. All 18 consolidation groups below are supported by site-specific notes in the sites inventory documenting parcel contiguity and consolidated acreage. For several grou ps, the consolidated develo pment site also includes one or more additional parcels that individually exceed 0.5 acre; the table below shows both the small- 515

parcel subset (parcels under 0.5 acre only) and the full consolidated site (all parcels comprising the development), since the site’s realistic capacity reflects the assembled parcels together, not the small parcels in isolation.

TOTAL 45 12.90 436 54 23.69 905

3001 Bristol Street (APN 418-131-10) This 0.43-acre parcel is designat ed General Commercial (GC) in the General Plan and zoned C1, which allows residential de nsity of 20 to 60 dwelling units per acre. The site's assigned realistic capacity of 20 units (8 lower, 4 moderate, 8 ab ove moderate income) equates to approximately 46.7 dwelling units per acre – within th e density range permitted by the existing zoning, without reliance on lot consolidation with an adjacent parcel.

The feasibility of new residential development on a parcel of this size is supported by comparable projects in Costa Mesa. A 6-unit development including 1 moderate-income unit, currently in the City's development review process on a 0.42-acre site – nearly identical in size to 3001 Bristol Street – is proposed at a density of 14.2 dwelling units per acre against a maximum allowed density of 12 dwelling units per acre. While that project's base zoning allows a lower maximum density than the C1 zoning applicable to 3001 Bristol Street, it demonstrates that parcels of comparable size in Costa Mesa are actively moving through the development review process at or above their maxi mum allowed density, supporting the feasibility of achieving higher-density residential development on a small site. The City has also approved live/work residential development on a similarly-sized underutilized site: th e Urban Plan Screening Project at 1540 Superior Avenue (APN 425-351-06) redeveloped a 0.43-acre, vacant light industrial building into 9 live/work units, including 3 lower-income units.
518

Appendix B: Sites Analysis B-33
The site is currently developed with a retail commercial center and surface parking lot at approximately 50 percent site utilization, consistent with the pattern of underutilized commercial parcels along the Bristol Street corridor that the City has identified for reside ntial redevelopment in this planning cycle, including the consolidated sites at 2966/2956 Bristol Street (Group L) and 2931/2927 Bristol Street (Group N) in the immediate vicinity. The site's improvement-to-land value ratio of 0.48 indicates that existing improvements represent less than half the value of the underl ying land, supporting the economic feasibility of redevelopment relative to the land's value. The site has existing infrastructure in place, is privately owned, and is listed as available; it was not relied upon in the prior Housing Element cycle. 2821 Bristol Street (APN 418-181-11) is a 0.43-acre vacant parcel currently used as a surface parking lot, located within the General Commercial (GC) General Plan designation and Commercial Limited (CL) zoning district, which allows residential density of 20 to 30 dwelling units per acre. Unlike the other 41 small parcels evaluated in this analysis, this site is not assumed to consolidate with an adjacent parcel and is evaluated on a standalone basis at its existing 0.43-acre lot size. The sites inventory notes that development interest for the site has been provided to the City in writing. Given the site's size and standalone development scenario, the City has revised its realistic capacity as sumption for this site to reflect development at the moderate-income affordability level rather than lower-income.

4. Development of Large Site Parcels
The 2021-2029 sites inventory includes four sites that are larger than 10 acres. These sites exceed the AB1397 size requirement and require additional analysis. The following background and analysis relates to each site in the inventory that exceeds that inventory. The City has conducted meetings with each of these major property owners to determine their future interest in developing housing on the identified properties. These properties when developed pursuant to the densities included within this Housing Element would be subject to the City’s inclusionary housing requirements which are in process and anticipated to be adopted per Program 2A. This supports the City’s assumptions of affordability on the sites described below. The housing element also includes Program 3R which commits the City to take actions to promote the development of large parcels at the densities and affordability levels identified within the housing element. There are no unit caps within the City which would limit the number of units which can be developed on these sites. That is subject to the densities provided within the City’s zoning code.

Fairview Developmental Center
The Fairview Developmental Center (FDC) is a State-owned property that is approximately 109 acres in size and located on Harbor Boulevard within Costa Mesa. The FDC served as one of the largest residential facilities for developmentally disabled persons in the State of California, and a closure plan was issued in April 2016 with the facility officially concluding its operations in December of 2025. The FDC was previously identified in the City’s 5
th cycle Housing Element (2013-2021) and the Ci ty has continued discussions with the State to determine the potential residential yield of the area taking into consideration the existing uses.

Senate Bill 188 (2022) allocated $3.5 million of State funds to the City to develop a specific plan for the FDC site, and to manage the land use planning process inte grated with a disposition process for the property, to be carried out by the California Department of General Services (DGS). The disposition of the property shall provide for affordable housing to the greatest extent feasible and shall be upon terms and conditions the director of DGS deems to be in the best interests of the State. The intent of the legislature is that the FDC property be utilized for a mixed-use development, including mixed-income housing. The development 519

Appendix B: Sites Analysis B-34
would include and prioritize afford able housing, including at leas t 200 units of permanent supportive housing, and open space.

The City issues a request for pr oposals and selected a consultant in 2022 to manage the community engagement process and prepare the specific plan, the Environmental Impact Report (EIR) including its associated technical studies , market and financial feasibility analys es, and coordinate with the City and State regarding the specific plan. Community en gagement was conducted th roughout 2023 and 2024, which informed alternative land use plans for consideration. The Planning Commission recommended, and the City Council approved a preferred land use plan for environmental study purposes and inclusion in the specific plan in August and October of 2025. The publi c draft specific plan was re leased for 30-day public comment in March 2026, and the pub lic draft EIR was made available for public comment beginning May 14, 2026, through July 1, 2026.

The City has established Program 3B to work with the State of California to establish the FDC area as a mixed-use and mixed-income community that priori tizes housing and promotes development at the densities and affordability levels identified within this housing element through creation of a specific plan that includes objective development standards, afford ability requirements and development incentives.

The City’s 6
th Cycle analysis includes an assumption of 2,300 dwelling units broken down into the very low, low, moderate, and above moderate-income categories. The State opened their application portal in January 2026 for interested developers to submit prop osals and be considered fo r selection as a master developer of the FDC site. As stated in Program 3B , the City anticipates Specific Plan adoption in summer/fall 2026 and the specific plan includes a maximum residential unit capacity up to 4,000 units.

Sakioka Lot 2
Sakioka Lot 2 is a 30.93-acre site located north of the 405 Freeway with General Plan Land Use designation that allows up to 660 residential units, 863,000 Square feet of office or retail use and a Floor Area Ratio of

1.0. The property is also located in the North Costa Mesa Specific Plan or up to 90 du/ac under and the newly amended Mixed-Use Overlay District (MUOD)
The site is currently under a development agreement (D A) that was recently extended for ten years until May of 2031. The City has had continued discussions with the property owners who have indicated there is the potential for future housing development on the site in strategic areas. This development would occur pursuant to the new densities identified within the Housing Element, which may lead to the development of more units than currently established under the DA. The property owner and City could potentially amend the current DA or the property owner may develop outside of the DA but under the zoning requirements of the North Costa Mesa Specific Plan in order to achieve more than 660 residential units in the future. Therefore, the existing DA does not present a cap or restriction on the future number of potential units on the Sakioka Lot 2 parcel. Furthermore, there are not affordability caps within the current DA which would limit the number of units which may be affordable. The City’s 6 th Cycle analysis
includes an assumption of 1,200 dwel ling units broken down into the ve ry low, low, moderate, and above moderate-income categories. The property owner has expressed interest in communications with the City in developing for residential uses within the 8-year planning cycle. Continued coordination with the property owner indicates sustained interest in pursu ing redevelopment, including residential uses, and reflects strong market interest in repositioning the site over the planning period. 520

Appendix B: Sites Analysis B-35
Former Restaurant and Parking Lot
Pacific Arts Plaza is an approximately 18.3-acre site located within the South Coast Plaza Town Center. The site is currently developed with a mix of office buildings and restaurant uses and is designated Cultural Arts Center (CAC) by the General Plan and has a zoning designation of Town Center (TC). The property is also located in the North Costa Mesa Specific Plan. Portions of the si te are under a Development Agreement. The existing development approvals referenced in the original Development Agreement that allows for a maximum Floor Area Ratio (FAR) of 1.55 and maximum building square footage of 1,227,978. The Development Agreement has expired as of August of 2023.

While the full 18-acre site could theoretically accommodate up to 1,620 dwelling units based on maximum densities of 90 dwelling units per acre, the City has ta ken a more targeted and co nservative approach in estimating realistic capacity. Residential development is only assumed on a limited portion of the site, specifically the area occupied by a closed restaurant and associated surface parking lot. This portion of the site is largely underutilized and presents the most immediate opportunity for redevelopment.

Consistent with this approach, the City has assumed a total capacity of 535 dwelling units for the site. This assumption reflects the portion of the property that is currently vaca nt or underutilized, rather than the entirety of the developed site, which continues to su pport active office and commercial uses. The City’s estimate is further supported by ongoing discussions with the property owner, who has indicated potential interest in introducing residential uses in strategic areas of the site for redevelopment during the planning period.

One Metro West (1683 Sunflower Avenue)6
One Metro West is an approved mixed-use multifamily redevelopment project located on a 15.23-acre site at 1683 Sunflower Avenue. The site is currently developed with office, warehouse, and manufacturing uses within an approximately 345,000-s quare-foot, one-story industrial building, demonstrating the redevelopment of an existing nonvacant, lower-inte nsity industrial/commercial site into high-density residential and mixed-use development. The approved project includes up to 957 apartment units, 6,000 square feet of ground-floor retail space, a 25,000-s quare-foot office building, 1.5 acres of publicly accessible open space, and related off-site improvements along Sunflower Avenue, including new bicycle lanes and landscaped medians. The project also includes a Development Agreement that provides public benefits, including 106 afford able units, consisting of 67 very low-income units and 39 low-income units, which are required to remain affordable for at least 40 years.

The City Council initially approved the project entitlements in 2021, including certification of the Final Environmental Impact Report, approval of the General Plan Amendment, Master Plan, Tentative Tract Map, Development Agreement, Rezone, and Specific Plan. The General Plan Amendment changed the land use designation from Industrial Park to High Density Residential, establishi ng a site-specific maximum density of 80 dwelling units per acre and a maximum of 1,057 units. The Rezone changed the zoning from Industrial Park to Planned Development Residential – High Densit y, and the Specific Plan establishes site-specific

development standards, design guidelines, zoning regulations, infrastructure systems, and implementation requirements for future project implementation.

At the time of the 2021 approval, the project remained subject to voter approval under Measure Y because the project involved major land use changes, including a General Plan Amendment, Rezone, Specific Plan, and more than 40 residential units. As a result, the 2021 ordinances were conditioned to become effective only after approval by the electorate. However, in November 2022, Costa Mesa voters approved Measure K, which amended Article 22 of the Costa Mesa Zoning Code to allow housing development in specified commercial and industrial areas without a separate electorate vote. The One Metro West site is located within the Measure K boundaries and therefore no longer requires voter approval.

In 2024, the applicant returned to the City to update the project approvals to reflect the Measure K changes and eliminate the prior Measure Y vo ter approval condition. On June 18, 2024, the City Council adopted Ordinance No. 2024-05 approving the amended De velopment Agreement, Ordinance No. 2024-06 approving the Rezone, and Ordinance No. 2024-07 approving the Specific Plan. These ordinances made the project approvals effective without a subsequent el ectorate vote. The 2024 amendments did not modify the approved development plans; instead, they clarified the effective date of the approvals and modified the timing of certain development impact fee and co mmunity benefit payments to assist with project implementation.

For Housing Element purposes, One Metro West provid es strong evidence that nonvacant, underutilized commercial/industrial sites larger than 10 acres can re alistically redevelop with high-density multifamily housing during the planning period. The project has progressed beyond conceptual interest: it has certified environmental review, approved land use entitlements, adopted implementing ordinances, an effective zoning designation allowing high-den sity multifamily residential development, a project-specific Specific Plan, a Development Agreement, and committed affordable housing units. The project’s continued advancement also supports the City’s reliance on similar nonvacant sites where zoning, site size, redevelopment patterns, and market conditions support multifamily or mixed-use residential development.

5. Accessory Dwelling Units
Accessory dwelling units, or ADUs, are housing units which may be developed in addition to an existing single- or multi-family residential use. These housin g units can be free-standing or attached to a primary structure and are intended to provide additional housing on an existing residential lot. Often ADUs provide housing for family members or are rented to members of the community.

In the 2021 Housing Element, the City relied on ADU produc tion projections to su pport RHNA capacity, estimating approximately 391 ADUs over the 2021–2029 planning period (or about 50 units annually ).

These projections were base d on observed increases in ADU activi ty between 2018 and 2021, as well as the anticipated continued impact of recent State legislation and local incentives promoting ADU development.

As part of this amendment, rather than relying on only projected ADU production, the City is crediting RHNA progress based on actual units reported through the City's Annual Progress Reports (APRs), reflecting permits issued and units completed. The majority of RHNA credit reported through this method consists of ADUs.

However, to provide context on performance and tre nds, the City has updated this analysis to compare projected assumptions with actual ADU activity during the 6th Cycle planning period (2021–2025)Table B-7 compares the City’s original AD U production assumptions from th e 2021 Housing Element with actual permitting and completion activity during the 6th Cycle planning period to date.

Source: California Department of Housing and Community Development. “Annual Progress Reports — Data Dashboard and Downloads.” Accessed May 20, 2026. https://www.hcd.ca.gov/housing-open-data-tools/apr-dashboard

Over the first five years of the planning period (2021-2025), th e City permitted a total of 374 ADUs , significantly exceeding the original annual projection of 50 units per year. This demonstrates that actual ADU production has outpaced initial expectations, particularly in later years as market familiarity, streamlined regulations, and local incentives have taken effect. Completed units have also increased steadily over time, reflecting a lag between permitting and construction but confirming sustained delivery.

Consistent with State law, ADUs continue to be permitted in all zones that allow residential uses residential zones. The City has supported ADU production throug h flexible local development standards, including reduced parking requirements and allowances for larger unit sizes compared to State minimums. 523

Appendix B: Sites Analysis B-38
Overall, while the City no longer relies on ADU projections for RHNA compliance, actual RHNA credit based on building permits and certificates of occupancy reported through the City’s APR demonstrate that ADUs remain a meaningful and growing component of the City’s housing supply. These outcomes validate the assumptions made in 2021 and reflect the effectiveness of both State legislation and local implementation efforts in facilitating ADU development.

To assist in furthering the recognition and understanding of ADUs potential within Costa Mesa and reach the City’s ADU development projections, Costa Mesa included Program 3E, which identified actions the City will take to promote and incentivize the development of ADUs during the planning period. The following summarizes the progress the City has made in implementing the program:
 In 2025, the City updated the ADU ordinance to be consistent with changes to State law.  In 2023, the City launched a new permitting and land management system known as the Totally Electronic Self Service Application (TESSA) to facilitate application processing and help monitor ADU trends and affordability levels.
 Established an ADU webpage to serve as a local clearinghouse of ADU information.  Posted California Housing Finance Agency ADU Grant Program and Orange County Housing Finance Trust Subsidized ADU Loan Program information on the City’s ADU webpage.  Invited architects and engineers to submit ADU plans for a Pre-Approved ADU Program.  Staff continues to research potential funding sources for affordable ADUs and make new information publicly available to Costa Mesans.

6. Water, Sewer, and Dry Utility Availability
All sites, including the additional sites identified as part of the 2026 amendment, were evaluated to ensure there is adequate access to water and sewer connections as well as dry utilities. Each site is situated with a direct connection to a public street that has the appropriate water and sewer mains and other infrastructure to service the candidate site. The City has sufficient total water and sewer capacity (existing and planned) to accommodate the 2021-2029 regional housing need. The City plans for future housing growth through the Mesa Water District Urban Water Management Plan (UWMP). This was most recently updated in 2020. Future sewer capa city is planned for through the Co sta Mesa Sanitary District Sewer System Management Plan (SSMP), which was most re cently amended and recertified by the Board of Directors in 2025.

B. Calculation of Unit Capacity
This section contains a description of the candidate sites identified to meet Costa Mesa’s RHNA need at all income levels. The full list of these sites is presented in Table B-8.

7. Realistic Capacity and Affordability Calculations
Costa Mesa’s 2021-2029 Housing Element sites analysis assumes that each identified candidate housing site will develop with at a range of income levels. Primarily, it is assumed that sites identified within Table B-8 will redevelop with the following affordability characteristics:
 40% of units available to residents in the low and very low-income categories 524

Appendix B: Sites Analysis B-39
 20% of units available to residents in the moderate-income category  40% of units available to residents in the above moderate-income category Costa Mesa recognizes that not all sites within the inventory will develop such that they meet these affordability assumptions and has included a 30% buffer on the total number of units to assist in accommodating potential differences in future housing development. This buffer is to accommodate the potential that sites may develop for 100% nonresidential uses, however recent development within Costa Mesa has indicated that is unlikely. Additionally, all housing element sites have been rezoned pursuant to meet the performance standards required as part of Government code section 65583.2, subsection (h)(1)(B) requiring that 100 percent residential uses are permitted on all housing element sites and that mixed-use projects must be provide at least 50 percent of the total floor area as residential uses. As such, 100 percent nonresidential development is not allowed on the sites identified for the housing element.

The City has a record of approving residential and mixed-use development on previously non-residential sites. The following developments have all occurred recently within the City’s urban plans, specific plans, overlays, or on non-residentially zoned sites. Many of these are described in more detail in Table B-4.  2277 Harbor Blvd – Previous motel use that underwent a rezone from C1 to PDR-HD and developed as a fully residential project with 200 apartment units.  671 W 17 th Street – Previous industrial brownfield site in the Mesa West Bluff Urban Plan which developed as a fully residential project with 177 live/work units.  1620 and 1644 Whittier Avenue – Previous industrial use in the Mesa West Bluff Urban Plan which developed as a fully residential project with 89 live/work units.  1500 Mesa Verde East Drive – Commercially zoned parcel along Harbor Boulevard which developed as a fully residential project with 215 senior apartments.  Brickyard East and West – Previous industrial warehouse uses along Placentia Avenue which developed as a fully residential project with 29 townhouse units.

To account for site-specific develo pment considerations and avoid assu ming development at theoretical maximum buildout, the sites inventory applies a realistic capacity factor of 80 percent of maximum allowable residential density. Recent development trends in Costa Mesa demonstrate that this assumption is reasonable and achievable. As shown in the project reference table, recently constructed, entitled, and proposed residential projects have developed across a range of densities, with numerous projects achieving or exceeding 80 percent of the maximum allowable density or development intensity. Examples include 125 Baker Street, which was constructed at approximately 99 percent of maximum density; 1957 Newport Boulevard, constructed at approximately 100 percent; The Plant, pr oposed at approximately 111 percent; and the Senior Center affordable housing project, proposed at approximately 91 percent of the applicable density benchmark. For certain live/work projects with in the 19 West and Mesa West Bluffs Urban Plan areas, residential development intensity was regulated through FAR rather than a maximum dwelling-unit- per-acre standard. For these projects, the analysis compares the approved or built FAR to the applicable maximum FAR. These examples similarly demonstr ate development approach ing maximum allowable intensity, including 1620–1644 Whittier Avenue at approximately 87 percent and 2025 Placentia Avenue at approximately 92 percent of maximum FAR.

The examples also include projects providing lower-income housing. The Senior Center project proposes 70 lower-income senior units at approximately 91 pe rcent of the maximum allowable density, while Costa 525

Appendix B: Sites Analysis B-40
Mesa Village provides 96 lower-income units at approximately 101 percent of maximum density. These examples demonstrate that development approaching or exceeding the 80 percent capacity assumption is achievable for both market-rate and affordable housing projects.

While individual projects may develop below 80 percent based on project-specific circumstances, the range of recent development demonstrates that densities approaching maximum allowable capacity are regularly achieved in Costa Mesa. Accordingly, application of an 80 percent realistic capacity factor appropriately accounts for project-level variability while remaining consistent with demonstrated local development trends.

Consistent with local housing market trends data pres ented earlier in this appendices, the City of Costa Mesa is seeing an increase in residential development and rarely receives requests for fully non-residential uses in the area identified within the candidate housing sites analysis.

The City has established goals and programs within the Housing Element aimed at identifying funding opportunities and partnering with the development community to increase the amount of affordable housing built in future developments. If the City is able to identify partnerships leading to fully affordable projects, that would also help to cover any potential shortfall in capacity in any of the four income categories. The City of Costa Mesa recognizes that should a “No Net Loss” situation occur, they will be required to identify additional sites and has analyzed additional potential housing sites within the Housing Element’s environmental clearance document.

There are several candidate housing sites in which the affordability assumptions differ from those presented above. Those sites include:
 Costa Mesa Senior Housing Project (APN 424-211-01). This site is owned by the City of Costa Mesa who has had previous discussions with a developer on a fully affordable project on this site. This site assumes 70 units which are all affordable at the lower income levels.  Fairview Developmental Center. This site is analyzed previously in the large site analysis portion of this appendices. This site is owned by the State of California and the City anticipates working in collaboration with the State to support the goal of developing affordable housing. The City has assumed that approximately 40% of the units on this site will be available to residents at the lower income levels, while 30% will be available to residents at the moderate-income levels. The remaining units are anticipated to be market-rate.
 Sakioka Lot 2. The City has conducted outreach meetings with this property owner and determined that it is realistic to assume that 15% of future units on this site may be available to residents at the lower income levels. This site has an existing development agreement.  Pacific Arts Plaza and Town Center. The City has conducted outreach meetings with this property owner and determined that it is realistic to assume that 15% of future units on this site may be available to residents at the low and very-low income levels. This site has an existing development agreement.

8. Specific Plan and Overlays
At the time the 6 th Cycle Housing Element was originally adopted, Costa Mesa implemented zoning regulations through a combination of base zones, over lay zones, urban plans, and specific plans. Urban plans were adopted as standalone documents outs ide the Zoning Code that provided supplemental development standards. The Mesa West Residentia l Ownership Urban Plan, 19 West Urban Plan, Mesa 526

Appendix B: Sites Analysis B-41
West Bluffs Urban Plan, and SoBECA Urban Plan, alon g with the Harbor Mixed-Use Overlay, established additional regulations applicable to specific areas of th e City in addition to base zones and specific plans, resulting in a complex regulatory framework.

The City approved the rezone and application of Mixed-Use Overlay District on Housing Element Sites in April 2026. As identified in Programs 3B and 3C , of the Housing Plan (Chapter 4) , the City proposes to rescind the urban plans, and established objectiv e development standards for those sites through amending the Mixed-Use Overlay District and other parts of the Zoning Code. Additionally, the City modified relevant existing Specific Plans, to accommodate the RHNA. The densities identified in Table B-8 reflect the revisions made to these areas to permit residential development at a higher densities. As of April 2026, the City has rezoned all sites identified in the housing element consistent Government Code § [65583 and 65583.2 (c)].

In an effort to implement both the required rezoning of Housing Element sites, facilitate housing development, and simplify the City’s zoning framework, the City Council took the following actions on April 7, 2026:
 Rezoned all Housing Element sites, except the Fa irview Developmental Center, by applying the MUOD, specifically amended to the MUOD (as Article 11 of Chapter V of Title 13 of the Costa Mesa Municipal Code) to apply specific Housing Element site provisions regarding permitted uses, minimum residential densities, increased maximum building heights, decreased setbacks, flexible open space standards, no minimum parking requirements, and ministerial review and approval. On Housing Element properties that are also within a specific plan, such that the provisions of the MUOD that allow a greater numbe r of residential units shall su persede and prevail over any conflicting provisions of the site’s base zone, specific plan, and any other applicable zoning provision.
 Amended other sections of the Zoning Code to encourage and facilitate residential development and redevelopment, such as reducing multifamily parking minimums, removing the requirement for additional parking for bedroom additions, establishing a streamli ned development review process, and permitting transitional, supportive, and employee housing in the community.  Amended the North Costa Mesa Specific Plan to reflect the application of the MUOD, with the specific provisions mentioned above, to Housing Element sites within the specific plan area.

building with
surface parking
located along a
one-directional,
two-lane stretch of
Newport Boulevard.

Adjacent to
residential
development..

Existing
improvements
include small
commercial and
restaurant
buildings, surface
parking, and vehicle
circulation areas.

Individual parcels
demonstrate
substantial
underutilization; for
example, 1974
Newport Boulevard
is developed at
approximately 0.24
FAR, or about 31%
of the allowable

0.75 FAR, and
contains
improvements
dating to 1950 with
a low ILV of
approximately 0.22.

These conditions
indicate aging
improvements,
substantial unused
development
capacity, and
potential for parcel
consolidation and
higher-intensity
redevelopment.
