These regulations also provide any special requirements that are applicable to specific uses. Land use regulations for base zoning districts and planned development and for overlay districts are located in the 200 and 300 Series. Additional land use regulations that apply citywide or to only some of the zoning districts, such as those pertaining to nonconforming uses and specific uses (e.g., accessory dwelling units, alcoholic beverage sales, emergency shelters, live-work, and residential care facilities), are located in the 500 Series.
Performance standards that govern all uses and activities are also located in the 500 Series.
B. Development Regulations. These regulations control the height, bulk, density/intensity, design, location, and appearance of structures on development sites. Development regulations for base zoning districts and for overlay districts are located in the 200 and 300 Series. Development regulations related to specific plans are in the 400 Series. Development regulations, applicable to some or all zoning districts, and objective design standards for residential, commercial, and industrial development are located in the 500 Series; these include regulations for accessory buildings, fences and walls, landscaping, lighting, nonconforming uses and structures, off-street parking and loading, and wireless communications facilities.
C. Administrative Regulations. These regulations contain detailed procedures for the administration of these regulations and include common procedures, Measure M procedures, processes and standards for ministerial approvals, discretionary entitlement applications, design review, site approvals, variances, zoning clearances, administrative approval, and development agreements along with special procedures required by State law. Authority for adopting and implementing Specific Plans is located in the 500 Series with additional procedures in the 600 Series. Administrative regulations, including procedures for General Plan and Zoning Code amendments, also are in the 600 Series.
D. General Terms and Use Classifications. The 700 Series provides a list of terms and definitions of the terms used in the Zoning Code.

B. Exception for State Affordable Housing Density Bonus. The calculation of fractions related to permitted bonus density units for projects eligible for bonus density pursuant to Government Code Section 65915 or any successor statute shall be done as provided by state law.
20.103.040 – Measuring Distances
A. Measurements are Shortest Distance. When measuring a required distance, such as the minimum distance between a structure and a lot line, the measurement is made at the closest or shortest distance between the two objects.
B. Distances are Measured Horizontally. When determining distances for setbacks and structure dimensions, all distances are measured along a horizontal plane from the appropriate line, edge of building, structure, storage area, parking area, or other object. These distances are not measured by following the topography or slope of the land.
C. Measurements Involving a Structure. Measurements involving a structure are made to the closest exterior wall or structural framing members of the structure, excluding any allowable projections into a setback, such as balconies, bay windows, canopies, eaves, and porches. Structures or portions of structures that are entirely underground are not included in measuring required distances.
D. Measurement of Vehicle Stacking or Travel Areas. Measurement of a minimum travel distance for vehicles, such as garage entrance setbacks and stacking lane distances, are measured down the center of the vehicle travel area. For example, curving driveways and travel lanes are measured along the center arc of the driveway or traffic lane.
E. Measuring a Buffer or Radius. When a specified land use is required to be located a minimum distance from another land use, the minimum distance is measured in a straight line from all points along the lot line of the subject project, in all directions.

2 0.103.060 – Determining Grade
A. Determining Grade. Grade is the location of the ground surface. For purposes of this Code, the grade of a building used to determine building height shall be determined by one or more of the following:
B. Average Grade. Average grade is a horizontal line approximating the ground elevation through each building on a site used for calculating the exterior volume of a building. Average grade is calculated separately for each building.
C. Existing Grade. Existing grade is the existing elevation of the ground at any point on a lot. Existing grade also may be referred to as natural grade.
D. Finished Grade. Finished grade is the lowest point of elevation of the finished surface of the ground, paving, or sidewalk within the area between the building and the lot line, or when the lot line is more than five feet from the building, between the building and a line five feet from the building.
E. Grade Plane. Grade plane is a reference plane representing the average of finished ground level adjoining the building at exterior walls. Where the finished ground level slopes away from the exterior walls, the reference plane shall be established by the lowest points within the area between the building and the lot line or, where the lot line is more than five feet from the building, between the building and a point five feet from the building.

20.103.100 – Determining Floor Area
The floor area of a building is the sum of the gross horizontal areas of all floors of a building or other enclosed structure, measured from the outside perimeter of the exterior walls and/or the centerline of interior walls.
A. Included in Residential Floor Area. Floor area includes all habitable space that is below the roof and within the outer surface of the main walls of principal or accessory buildings. In the case of a multi-story building that has covered or enclosed stairways, stairwells, or elevator shafts, the horizontal area of such features shall be counted only once at the floor level of their greatest area of horizontal extent. The area of mezzanines and sleeping lofts shall not be counted if the space is between two floors.
B. Included in Non-Residential Floor Area. For non-residential uses, gross floor area includes interior walkways, interior courtyards, walkways, paseos, and corridors covered by a roof or skylight.
Non-residential gross floor area does not include arcades, porticoes, and similar open areas that are located at or near street level or walkways in a shopping center and are accessible to the general public but are not designed or used as sales, display, storage, service, or production areas.
C. Excluded from Floor Area- All Uses. Floor area does not include: mechanical, electrical, and communication equipment rooms; bay windows or other architectural projections where the vertical distance between the lowest surface of the projection and the finished floor is 30 inches or greater; areas used for off-street parking spaces or loading spaces, driveways, ramps between floors of a multi- level parking garage, and maneuvering aisles that are located below the finish grade of the property.
20.103.110 – Determining Floor Area Ratio
The floor area ratio (FAR) is the ratio of the floor area, excluding the areas described below, of all principal and accessory buildings on a site to the site area. To calculate the FAR, floor area is divided by site area and typically expressed as a decimal. For example, if the floor area of all buildings on a site totals 20,000 square feet, and the site area is 10,000 square feet, the FAR is expressed as 2.0.
A. Excluded from Floor Area in Calculating FAR. The following are excluded from the floor area when calculating FAR.
1. Underground Areas. Floor area located at least 18 inches below finished grade, including basements.
2. Parking. Parking areas located below finished grade or finished floor of habitable space where the vertical distance between finished grade and finished floor is five feet or less. Structured parking areas located above finished grade where the vertical distance between finished grade and the floor of the parking level is five feet or less.
3. Sideloaded or Detached Residential Garages. Sideloaded or detached garages in Residential zones not exceeding 450 square feet, located on the side or to the rear of residential structures, a minimum of 25 feet away from the front lot line, and accessed by a driveway.

20.103.130 – Determining Lot Frontage
A. Corner Lot. In the case of a corner lot, the front of the lot is the narrowest dimension of the lot with street frontage. On a reverse corner lot, the street side yard is also considered the lot frontage.
B. Through Lot. In the case of a through lot, the front yard of the lot abuts the street that adjoining lots use to provide primary access into the dwelling.
20.103.140 – Determining Setbacks
A setback line defining a required yard is parallel to and at the specified distance from the corresponding front, side, or rear lot line. The following regulations for determining yards apply when a lot abuts a proposed street or alley.
A. Yards Abutting Planned Street Expansions. If a property abuts an existing or proposed street for which the existing right-of-way is narrower than the right-of-way ultimately required for the street, the required setback shall be established from the future right-of-way rather than the property line.
B. Yards on Alleys.
1. If a side lot line abuts an alley, the yard shall be considered an interior side yard rather than a corner side yard.
2. In computing the minimum yard for any lot where such yard abuts an alley, no part of the width of the alley may be considered as part of the required yard.
C. Yards for Flag Lots. On a flag lot, a front setback shall be established for the access corridor and for the interior or the lot along the interior lot line parallel to the lot frontage.
Exclude non-habitable
accessory structures
less than 120 square
feet of roof area.

20.201.010 – General Purpose
The general purpose of residential zoning districts is to:
A. Provide appropriate locations for residential development to meet the housing needs of Chino residents with a mix of housing types of varying prices and rents.
B. Provide stability and protection for existing residential neighborhoods.
C. Ensure that new development is compatible with existing homes in residential neighborhoods with standards for building design, siting, screening, buffering, landscaping, and parking.
D. Provide adequate light, air, privacy, outdoor living area, and open space for homes.
E. Promote community resilience to hazard events by enabling the use of backup generators, solar energy systems with battery backups, and home microgrids, subject to appropriate standards for public safety and emissions controls.
F. Protect residents from the harmful effects of excessive noise, traffic congestion, air pollution and natural and man-made hazards.
G. Provide opportunities for public and semi-public uses to locate within the residential communities which they serve.
H. Allow home occupations compatible with a suburban context that do not generate significant visitor traffic to expand workforce participation, reduce vehicle miles travelled, and promote entrepreneurship.
20.201.020 – District Purposes
The specific purpose of each residential zoning district is as follows:
A. Residential/Agricultural (RD 1). The purpose of this district is to provide for very large lot residential development in a rural environment. Detached single-family homes and related rural uses,
CHINO ZONING CODE UPDATE
BASE DISTRICTS CHAPTER 20.201
Series 200 – Base District Redline Amendments May 20, 2026 Series 200 – Page 2
such as horse-keeping and small-scale agriculture consistent with residential areas, are allowed. This district also provides a buffer between Chino and other communities and between urban areas and permanent intensive agricultural areas. The RD 1 district allows up to one dwelling unit per adjusted gross net acre and up to 1.25 dwelling units per adjusted gross acre with the provision for affordable housing.
B. Residential/Agricultural (RD 2). The purpose of this district is to provide for semi-rural and suburban lifestyles on lots that are larger than commonly available in suburban subdivisions. This district is typified by large lot development that includes horse-keeping and other semi-rural uses.
The RD 2 district allows one to two dwelling units per adjusted gross net acre and up to 2.5 dwelling units per adjusted gross acre with the provision for affordable housing.
C. Residential (RD 4.5). The purpose of this district is to encourage a predominately single-family suburban residential development similar to that found in many of the city’s existing residential tracts.
The RD 4.5 district allows between 2 and 4.5 dwelling units per adjusted gross net acre and up to 6 dwelling units per adjusted gross acre with the provision for affordable housing.
D. Residential (RD 8). The purpose of this district is intended as a transition zone from low density single-family areas to higher intensity commercial, industrial and multiple family residential areas.
Attached and detached dwellings are permitted in this district. It provides primarily for single-family detached housing on lots that are smaller than commonly available in other residential neighborhoods in Chino. The RD 8 district allows 4.5 to 8 dwelling units per adjusted gross net acre and up to 10 dwelling units per adjusted gross acre with the provision for affordable housing.
E. Residential (RD 12). The purpose of this district is to encourage a wide range of residential land uses from attached dwellings to townhouse type developments. It provides for a variety of residential product types, including attached single-family homes, bungalow courtyard development, attached dwellings, and townhomes. Small lot single-family homes are also permitted. The designation is intended to encourage innovation in housing types that can expand opportunities for homeownership in Chino. Developments within RD12 areas may provide amenities not generally found in suburban subdivisions, such as common open space and recreational areas. The district allows 8 to 12 dwelling units per adjusted gross net acre and up to 15 dwelling units per adjusted gross acre with the provision for affordable housing.
F. Residential (RD 14). The purpose of this district is to provide an area for attached townhome and condominium projects, including attached single-family homes, bungalow courtyard development, attached dwellings, and townhomes. Small lot single-family homes are also permitted. The designation is also intended to encourage innovation in housing types that can expand opportunities for homeownership in Chino. Developments within RD14 areas may provide amenities not generally found in suburban subdivisions, such as common open space and recreational areas. Medium density residential uses in this district provide a mix of urban and suburban amenities including attached units with enclosed garages and common recreational open space. The RD 14 district permits from 12 to 14 dwelling units per adjusted gross net acre and up to 17.5 dwelling units per adjusted gross acre with the provision for affordable housing.
G. Residential (RD 20). The purpose of this district is to provide for a relatively high density residential environment including attached single-family homes, bungalow courtyard development, attached dwellings, and townhomes. Small lot single-family homes are also permitted. The designation
CHINO ZONING CODE UPDATE
BASE DISTRICTS CHAPTER 20.201
Series 200 – Base District Redline Amendments May 20, 2026 Series 200 – Page 3
is also intended to encourage innovation in housing types that can expand opportunities for homeownership in Chino. Developments within RD 20 areas may provide amenities not generally found in suburban subdivisions, such as common open space and recreational areas typified by fourplex developments and garden apartments. The RD 20 district permits 14 to 20 dwelling units per adjusted gross net acre and up to 25 dwelling units per adjusted gross acre with the provision for affordable housing.
20.201.030 – Use Regulations

CHINO ZONING CODE UPDATE
BASE DISTRICTS CHAPTER 20.201
Series 200 – Base District Redline Amendments May 20, 2026 Series 200 – Page 11
than 10 feet above finish grade. In addition, the single-story feature shall have a minimum depth of 5 feet for a minimum of 60 percent of the length of each street facing elevation. c. New homes and additions to existing homes shall be single-story on lots that directly abut lots with existing single-story homes. The CommjunityCommunity Director of Development Services or the Planning Commission, as applicable, may approve exceptions to this requirement on a case-by-case basis when any of the conditions listed below exist.
i. The difference in the finish grade elevation between the lots is substantial enough to reduce views of the second-story portion of the proposed home; ii. The distance between the adjacent homes will reduce views into the homes or yard areas;
iii. The orientation of the homes is such that the exterior walls do not directly face each other;
iv. The shape or configuration of the lots is such that a substantial portion of the lot lines do not directly abut each other;
v. Existing accessory structures in the rear yard areas provide a barrier to mitigate privacy impacts between the primary residential units; or vi. Any other unique site circumstances that may effectively reduce privacy impacts to the existing adjacent single-story home.
d. The Director of Development Services or the Planning Commission, as applicable, shall consider public input in addition to information provided by the applicant to evaluate privacy impacts to adjacent property owners. This information shall include, but not be limited to, line-of-sight studies, site photographs, dimensioned site and building cross sections, three-dimensional or photo simulation models, or any other information deemed necessary by the Director of Development Services or the Planning Commission, as applicable, to consider the request. In reviewing the request, the Director of Development Services or the Planning Commission, as applicable, shall consider and establish the following findings:
i. The granting of the exception is consistent with the intent of the Zoning Ordinance to eliminate or minimize privacy impacts between existing residential homes and proposed homes on adjacent lots;
ii. That the adjacent property owners have been duly noticed, and that public input has been considered to ensure that the privacy of adjacent property owners is not adversely impacted;
iii. That there are specific circumstances applicable to the subject property and adjacent property that effectively eliminate or minimize privacy impacts between the homes; iv. That the proposed home incorporates design features that serve to eliminate or minimize privacy impacts between the homes.

BASE DISTRICTS CHAPTER 20.201
Series 200 – Base District Redline Amendments May 20, 2026 Series 200 – Page 12
e. Two-story homes that back up to a public street shall require 36-inch box street trees to be located in the right-of-way along rear of the homes at a spacing of 30 feet apart to soften building mass and buffer the homes from the street.
f. A 15-foot minimum clearance shall be provided between the second floors of homes that have a full two-story height building mass at interior side elevations. g. The rear building elevations of two-story homes shall have a combination of vertical and horizontal articulation such that an unbroken horizontal wall surface does not exceed a length of 30 feet and so that at least one feature is utilized that provides a break in the massing between the first and second story. A minimum one-foot variation in offset between wall planes shall be provided to satisfy this requirement. Examples that may satisfy this requirement include stepping back the second floor, providing pop-outs, insets, one-story roof elements, and changes in second story roof planes.
D. Existing Single-Family Homes. The intent of this provision is to encourage second-story additions that are designed to be compatible with the character of the neighborhoods where they are located while being sensitive to the privacy of adjoining neighbors. Review of two-story additions shall consider the design, placement, and location of a second-story addition so it minimizes privacy impacts to the extent feasible for the individual circumstances. The following regulations apply to second-story additions to existing single-family homes:
1. Two-story additions shall be designed with a building mass and scale that is similar to homes in the surrounding neighborhood.
2. Two-story additions shall be consistent with the architectural character of the neighborhood.
3. The design of two-story additions shall minimize privacy impacts on adjacent single-story homes. In particular, windows should be positioned to minimize direct views into the rear yard of adjacent single-story homes, and in no case, be positioned to provide direct views into windows of an adjacent home. The intent of this provision is not to eliminate windows on second-story additions, but rather to ensure that the design and placement of windows enhance the architectural quality of the home without creating privacy impacts on adjacent homes.

B. Additional Development Standards. The following additional standards apply to lots and structures located in mixed use zoning districts. Mixed use design standards are in Section 20.507.060.
Deviations from these standards may be approved with a development agreement and a commitment to community benefits.
1. Calculation of Residential Density. Where residential uses are allowed by a Measure M vote, the maximum density is 20 units per net acre, calculated on the basis of the total site area of the development plus the area of abutting local streets and alleys.
2. Reduced front and street side yards. The required minimum front and street side setbacks may be reduced five feet to provide active frontages with pedestrian-oriented amenities.
3. Required building wall on designated streets. Along commercial corridors in the BMU, where existing buildings are at or within five feet of the front setback line, building walls shall be constructed along or within 10 feet of the front setback line for a minimum of 50 percent of the primary street frontage. This is the “build-to” line. On reverse corner lots, if the street side yard is on an arterial street, it shall be subject to the required building wall standard. This requirement may be waived by the Director of Development Services upon finding that:
a. Where ground floor residential uses are proposed, decks and substantial landscaping will be located between the build-to and ground-floor residential units as a buffer; b. Entry courtyards, plazas, entries, or outdoor eating areas are located between the build-to line and the building requiring the building wall to be setback further from the front setback line; and
c. The building incorporates an alternative entrance design that creates a welcoming entry facing the street.

FAR Bonus Requested X 100 = Points Required
Maximum FAR Bonus
Increment Allowed
Variables used in the bonus point calculation are as follows:
a. FAR Bonus Requested. The amount of bonus FAR requested is based on an applicant’s development proposal; it is above the maximum base FAR allowed for the mixed use district where the project is located.
b. Maximum FAR Bonus Increment Allowed. The difference between the maximum FAR allowed and base FAR in each mixed use district is the maximum FAR bonus increment. The maximum bonus FAR increments for each mixed use district are as follows:
i. RMU District: 0.4 for parcels five acres or more in size; 0.7 for parcels with less than five acres
ii. BMU: 0.7
iii. EMU: 0.3
2. Points Counted Toward FAR Bonuses. The points awarded for providing individual on-site or off-site amenities shall be aggregated and counted towards the maximum allowable FAR on the site using the formula in subsection (B)(1).
3. Alternative Calculation of Bonus Floor Area. If requested by an applicant as an alternative to the points system, the Director of Development Services may approve bonus floor area up to the maximum increments allowed in each mixed use district as follows:
a. Alternative Calculation Method. For each one percent of construction costs allocated as an additional expenditure for one or more specific amenities listed in Table 20. 202-3, a 1.5 percent increase in the allowable floor area shall be granted. b. Number of amenities required. The number of specific amenities required shall be based on project size as follows:

20.206.010 – General Purpose.
The purpose of this chapter is to establish a Planned Development (PD) District as a floating zone to allow for one or more properties to be developed under a developer -initiated comprehensive development plan that provides for coordinated development and a particular mix of uses and character envisioned by the General Plan, with design and development standards crafted to respond to site conditions in order to:
A. Provide developers with a procedures to achieve greater flexibility in regulations such as building relationships, setbacks, height limitations, floor area ratio (FAR), lot sizes, types of structures, parking, landscaping, and the amount and location of open space that support a development concept that might not be allowed with base zoning district standards and master plans under the Master Plan Overlay.
B. Ensure substantial compliance with and implementation of the land use and density policies of the General Plan and any applicable specific plan.
C. Allow for more detailed small area planning for sites within larger master-planned areas.
D. Provide for efficient and cost-effective public facilities and services.
E. Allow for creative development projects that incorporate design features that provide greater amenities than would likely result from conventionally planned development under base district regulations.
F. Protect public health, safety, and general welfare without unduly inhibiting developers attempting to secure the advantages of modern, large-scale site planning for residential, commercial, or industrial purposes.
A PD District shall also be used for adoption and administration of specific plans, prepared pursuant to the Government Code. The PD District also is intended to provide the implementation framework for the MPO Master Plan Overlay established by Chapter 20.305 (Master Plan Overlay District), which requires a master plan as a precondition of development of a site subject to an MPO designation.
20.206.020 – Zoning Map Designation.
A PD District shall be noted on the Zoning Map by the designation “PD,” followed by the number of the Planned Development or specific plan based on order of adoption.

20.206.030 – Use Rregulations.
No use other than an existing use is permitted in a PD District except in accordance with a valid PD Plan or adopted specific plan adopted pursuant to the procedures in Section 20.602.150 (Modification Procedure for Conditions of Approval). Any permitted or conditional use authorized by this Code may be included in an approved PD Plan or an adopted specific plan consistent with the General Plan land use designation(s) for the property and, if required, a Measure M vote.
20.206.040 – Development Standards.
A. Minimum Area. The minimum area of a PD District shall be as follows; however, the City Council may approve a District smaller than the minimum area if it finds that rezoning to PD would provide greater benefits to the general welfare of Chino’s residents and property owners than development under a base district zoning because of unique characteristics of the site or the proposed use.
1. Mixed Use Zoning Districts: One acre
2. Other Zoning Districts: Two acres.
B. Residential Open Space. Common and private residential open space shall be required for housing units, with variable standards allowed for specific building types. The total open space provided for residents under a PD Plan shall be substantially the same as the open space required by the prior base district for the total area of the planned development or what would otherwise be required for the proposed uses.
C. Residential Unit Density. Except where a density bonus is granted in compliance with the City's residential density bonus regulations in Chapter 20.512 or the State density bonus law, the total number of dwelling units in a PD Plan shall not exceed the maximum number permitted by the General Plan density for the total area of the planned development designated for residential use, if applicable, excluding areas devoted to public and private streets, creeks, and storm drains. If the General Plan does not establish a residential density, the City Council shall set a density limit in approving the PD Plan and a Measure M voite may be required.
D. Performance Standards. The Performance Standards prescribed by Section 20.501.020 (Performance Requirements), apply.
E. Other Development Regulations. Minimum lot area, yard requirements, building heights, and other physical development standards shall be as prescribed by the PD Plan. Each PD Plan shall establish development standards that, at a minimum, address the following:
1. Land use;
2. Circulation of traffic, bicycles, and pedestrians;
3. Landscaping, buffering, and screening;
4. Specific density and intensity as appropriate for each land use and building type;
5. Minimum lot dimensions and maximum lot coverage by buildings and structures;
6. Minimum yards;
7. Maximum building or structure heights and maximum height of fences and walls;

The purpose of the overlay districts for affordable housing – the Affordable Housing Overlay (AHO) district and the Mixed Use Overlay (MUO) district – is to promote the development of affordable housing for low and very low income households in specific areas identified in the General Plan at densities of up to 30 dwelling units per acre if affordability requirements established in this section are met. More specifically, the AHO and MUO allow residential uses where they would not otherwise be allowed and provide for additional density in return for projects providing more affordable housing. The AHO is intended for standalone affordable housing projects, while the MUO provides for mixed use development with affordable housing either on upper floors or in separate buildings. This section also provides the residential development community two alternatives for construction of affordable housing within market-rate development and offers a streamlined process for administrative review of qualifying projects with affordable housing using checklists and objective standards as required by State law.
20.306.020 – Relation to Base Zoning
The AHO and MUO district regulations shall apply in the case of a conflict with the base zoning district regulations when a housing project is proposed. However, when an applicant proposes only non-residential uses, then only the base zoning district land use regulations and development standards apply. The AHO and MUO regulations and development standards only apply to proposed housing projects.
20.306.030 – Permitted Uses
Table 20.09-4306-1 identifies residential land uses permitted in the AHO and MUO districts in addition to the uses that are permitted within the existing base zoning district.

20.306.100 – Alternatives
In lieu of providing the affordable units in the housing development project required by Section 20.09306.050 (D) and 20.306.040 (I), the requirements of those subsections may be satisfied through one or more of the alternatives set forth below.
A. In-Lieu Fee.
1. For housing development projects proposing up to 20 units, the developer may, by right, pay a fee in lieu of providing affordable units on site.
2. For housing development projects proposing more than 20 units, the developer shall only be allowed to pay in-lieu fees if the Planning Commission makes a finding that providing affordable units on-site would result in an extreme financial hardship to the developer and make the proposed project financially infeasible. The developer shall submit a request to pay a fee in lieu of providing affordable units on site as part of the project application. Such request shall include sufficient documentation and financial analysis to allow the Planning Commission to make the required findings. At the City’s discretion, the City may contract with a third-party financial consultant to evaluate the documentation and analysis submitted by the applicant and make a recommendation to the City regarding the issues of extreme financial hardship and financial infeasibility. The developer shall be required to reimburse the City for all costs related to hiring any such third-party consultant, which shall be in addition to any other required application fees. The demonstration of financial hardship and infeasibility may be based on, among other things, such factors as project size, site constraints, and/or excessively large
CHINO ZONING CODE UPDATE
OVERLAY DISTRICTS CHAPTER 20.30
Series 300 – Overlay Districts Redline Amendments May 20, 2026 Series 300 – Page 32
affordability gaps, or upon a demonstration that in the absence of allowing for payment of in- lieu fees, the imposition of the affordable housing production requirements in this Section would violate the California and/or United States Constitutions because it would be a regulatory taking of property without fair and just compensation.
3. In-lieu fees shall be paid as follows:
a. The amount of the fee shall be calculated using the fee schedule established by resolution of the City Council at the time the fee is paid.
b. One-half of the in-lieu fee required by this subsection shall be paid (or a letter of credit posted) prior to issuance of a building permit for all or any part of the housing development project. The remainder of the fee shall be paid before a certificate of occupancy is issued for any unit in the housing development project. In a phased project, payment of fees also may be allowed in phases, corresponding to the number of units in each phase.
c. The fees collected shall be deposited in the Overlay District Affordable Housing Fund established by Section 20.305.13009 (M).
B. Land Dedication. In lieu of providing affordable units on-site, a developer may request City Council approval to dedicate land to the City or to a City-approved affordable housing developer that the Director of Development Services determines is suitable for the construction of the required number of affordable units and is within one mile of the project site. To accept a land dedication in lieu of on- site affordable units, the City Council must determine the fair market value of the dedicated land is equivalent to or greater than the amount of in-lieu fees that would have been needed to satisfy the housing development project's affordable housing obligation and that the required number of units for very low income residents will be built on this land based on a proposed conceptual site plan and proforma financial analysis demonstrating project feasibility with available funding.
1. The developer must submit evidence that the land proposed to be dedicated is under the developer’s control, will be conveyed at no cost to the City or a City-approved affordable housing developer with experience building rental housing for very low income households, is free of any liens, all property taxes and special taxes have been paid, does not contain any hazardous materials, has the appropriate General Plan designation and zoning to allow construction of the required number of units, and has the necessary infrastructure and public improvements to support the required number of affordable units. Only sites within an AHO or MUO district that are within one mile of the project site can be considered for land dedication.
2. The developer must disclose whether any hazardous materials were previously contained on the site; and hazardous materials were previously remediated, the developer must provide evidence that the cleanup was performed in accordance with applicable law.
3. The land proposed for dedication cannot have been improved with any residential use for at least five years prior to the submission of a land dedication proposal.
4. The affordable units to be constructed on the dedicated land shall be at least 20 percent of the total number of units in the project, and these units must be rental units affordable to very low income households.

. Off-site Construction. A market-rate developer may enter into an agreement with an affordable housing developer to construct, own, and operate affordable rental housing units required by Sections
20.09.090306.050 (D) and 20.306.040 (I), provided:
1. The affordable housing developer is approved by the Director of Development Services on the basis of recent relevant experience;
2. The affordable housing developer does not request any financial assistance from the City;
3. The affordable rental housing units shall be constructed prior to or concurrently with the market-rate development triggering the affordable housing requirement; and
4. At least 20 percent of the total number of units to be built on the site shall be rental units affordable to very low income residents.
20.306.110 – Review Procedures
A. Preliminary Review. A developer requesting additional density above 26 units per adjusted gross acre for a rental project under Section 20.09.090 20.306.040 (D) shall submit an application for preliminary review, accompanied by the required application fee, for feedback prior to the submittal of any formal requests for approval of additional density. The purpose of the preliminary review is to determine whether the proposed development is in substantial compliance with applicable planning regulations and to establish the basis and procedures for granting the additional density. The following information is required to be submitted for preliminary review in the form of a proposed affordable housing plan in addition to information required by the Department’s preliminary review checklist:
1. Evidence that the project includes the qualifying percentages of affordable units set forth in Section 20.09.090(D)20.306.040 to justify the additional density requested;
2. Calculations showing the maximum base density and the density with the additional units;
3. Number and percentage of total units that are proposed to meet affordability criteria and the income level to which the units will be restricted; and
4. A description of any proposed waivers or reductions of development standards or other zoning requirements, consistent with the provisions of Government Code Section 95915 (k).
B. Site approval required. All residential development or mixed use development with residential units in an AHO or MUO district shall require approval of a Site Approval application as outlined under Section 20.23.090603.070 (Site Approvals). For residential development and mixed use development with residential units, design review by the Planning Commission shall be undertaken only to determine compliance with the City’s objective design standards using the Site Approval process.
C. Additional findings for approval. The Planning Commission shall grant a Site Approval if it makes the findings required by Section 20.23.090603.070 (Site Approvals) and the following additional findings:
1. The proposed development meets the affordability criteria for the requested density in accordance with the requirements of subsection (D) and (I); and
2. The increased density would not have a specific adverse impact, as defined in paragraph (2) of subdivision (d) of Section 65589.5 of the Government Code, upon public health and safety or

20.401.010 – Purpose and Applicability
Specific plans are regulatory documents established by the City to carry out specific purposes, as authorized by the Government Code Section 65450 et. seq., for specific geographic areas shown on the Zoning Map.
They are governed by a set of regulations, which address specific subjects, such as land use, physical development, community design, transportation, and public improvements, or impose requirements for detailed master plans that may be applicable in sub-areas within the specific plan area. The provisions of a specific plan may be combined with provisions of base or overlay zoning districts for the area to which the specific plan applies, and the more restrictive provisions will govern. Specific plan provisions also may be substituted for citywide provisions included in the Zoning Code or Title 19 (Subdivisions), as more specifically specified in the specific plan.
20.401.020 – Preparation, Adoption, and Amendment
A. A specific plan shall be prepared, adopted, amended, and repealed as specified in Section 20.603.020 (Preliminary Review) of this Code, except that a specific plan shall be adopted by resolution and may be amended as often as deemed necessary by the City Council.
B. Specific plans may be repealed when they are no longer needed, either because an area has been developed as originally envisioned or because General Plan policies and citywide regulations provide an appropriate framework for development review. Periodic review of specific plans and repeals of out-of- date plans will streamline zoning administration.
20.401.030 – Post-Approval Administration
A. Specific plan areas shall be designated on the Zoning Map by number (SP-#) with a reference to the adopting resolution.
B. A specific plan adopted by resolution of the City Council shall be administered as prescribed by the Council, consistent with the Government Code Section 65450-65457.
Note to reviewers: Individual specific plans need not be codified as was done with the Central Avenue Specific Plan. They can be stand alone documents approved by resolution.
