1 SCAG Regional Accessory Dwelling Unit Affordability
Analysis
INTRODUCTION
As cities prepare site inventory analyses for the 6th Housing Element Planning Cycle, the last step in the process allows cities to determine whether the housing element demonstrates sufficient land suitable and available for residential development to meet the jurisdiction’s Regional Housing Needs Allocation (RHNA) for each designated income level or if further program actions are required to accommodate a shortfall. Government Code section 65583.1 details how jurisdictions may consider alternative means of meeting RHNA beyond vacancy and underutilized sites. The potential for accessory dwelling units (ADUs) or junior accessory dwelling units (JADUs) is one of these available alternative means. A jurisdiction must include an analysis of the anticipated affordability of ADUs in order to determine which RHNA income categories they should be counted toward.
SCAG conducted this analysis in order to provide local governments in the region with assumptions for ADU affordability that can be used to assign ADUs to income categories for the purpose of Sixth Cycle Housing Elements. Affordability can be determined in a number of ways. This analysis examines current market rents for reasonably comparable rental properties, using platforms such as Craigslist, Zillow, and Westside Rentals and key words to identify units that appear to be ADUs1 . The analysis relies on a survey
of rents of 150 existing ADUs conducted between April and June 2020. Efforts were made to reflect the geographic distribution, size, and other characteristics of ADUs across the following counties/subregions2
. For example, LA County is separated into two categories in order to better account for the disparities in housing costs between coastal and inland jurisdictions. LA County I (59), includes City of Los Angeles, Las Virgenes‐Malibu, South Bay Cities, Westside Cities
LA County II (20), includes all other LA County jurisdictions Ventura County (22)
Orange County (46)
Riverside and San Bernardino Counties (11)
1 Key words used in searching rental listings included “ADU,” “in‐law,” “granny,” “detached guest studio.”
2 Please note that no listings were found in Imperial county owing to the lower occurrence of ADUs in Imperial county. Suggest using SB/RV as a proxy, or contacting SCAG staff ([email protected]) or HCD staff to discuss possible approaches should ADUs be a desired part of the housing element update. 2 ADUs and data on ADUs do not exist uniformly across the region, thus we encourage jurisdictions to refer to the raw data (included in Appendix A) to help gauge how representative this sample is to their ADU program. Jurisdictions may determine that the geographic distribution, age of structures, number of bedrooms, and square footage of the units surveyed in this analysis do not reflect the ADUs being built in their community and pursue their own analysis. A step‐by‐step explanation of how this report was conducted will allow jurisdictions to replicate the analysis with different data should they choose to do so. This analysis consists of five steps:
A.) Calculate maximum rent limits for RHNA income categories for both one‐person and two‐ person households by county
B.) Conduct survey of rents for ADUs in the SCAG region C.) Use regional survey to determine proportion of ADUs within each income category for both one‐person and two‐person households
D.) Make assumption for what percentage of ADUs will be occupied by one‐person households and two‐person households
E.) Use (D) to combine proportions from (C) into single breakdown of rented ADUs by income category
The final affordability assumptions resulting from this analysis are as follows:3 LA County I LA County II Ventura County Orange County San Bernardino/Riverside Counties Extremely Low 15.0% 15.0% 15.0% 15.0% 15.0%

Conduct survey of rents for ADUs in the SCAG region The survey, included as appendix A, includes location, rent, sq. ft (if available), and a link for 150 accessory dwelling units across the SCAG region. SCAG searched for key terms (ADU, in‐law, backyard cottage, granny flat, etc.) across a variety of rental housing search engines (including Craigslist, Zillow, Westside Rentals).
ADUs were identified in 52 of the region’s jurisdictions. Rental prices ranged from $650 to $4,800, with a median rent of $1,600. Sizes ranged from 175 square feet to 1,650 square feet, with a median size of 500 square feet.
C) Use regional survey to determine proportion of ADUs within each income category for both one‐person and two‐person households

8 D) Make assumption for what percentage of ADUs will be occupied by one‐person households and two‐person households
The lack of comprehensive studies and surveys of ADUs in the SCAG region presents myriad challenges when making assumptions regarding occupancy and affordability. Without such data, SCAG relied on survey data collected by other jurisdictions with more established ADU programs. Portland, Oregon in particular offers the most robust insights as it has surveyed both owners and renters of permitted ADUs.
Based on 2018 survey results below from Portland, we will assume that ADU residents are split 50% as one‐person households and 50% as two‐person households. Assuming household sizes greater than two may increase the assumed affordability of ADUs if these households have higher median incomes. Using only one‐ and two‐person households yields a more conservative estimation of ADU affordability.

1. AFFORDABILITY BREAKDOWN OF NON‐RENTED ADUS
As noted in the Portland survey as well as scholarship on the subject, one prevalent use for ADUs is as housing for family members or care takers who are not charged rent. There is no reliable data on the number of ADUs that are rented for free in the SCAG region, but three studies from the Bay Area and Portland have attempted to estimate the rate of non‐rented ADUs: A 2012 UC Berkeley publication entitled “Scaling up Secondary Unit Production in the East Bay” indicates that approximately half of all secondary dwelling units are unpaid.4
A 2018 report entitled “Jumpstarting the market for ADUs” surveyed ADUs in Portland, Seattle, and Vancouver and found that approximately 17% of ADUs were occupied by a friend or family member for free.5
A 2014 analysis entitled “Accessory dwelling units in Portland, Oregon: evaluation and interpretation of a survey of ADU owners” found that “18% of Portland ADUs are occupied for free or extremely low cost.”6
Based on these surveys, this analysis will conservatively assume that 15% of ADUs will be available at rents affordable to Extremely Low‐Income households.
