Summary of Key ADU Features: ADUs can be used to accommodate RHNA Growth needADUs can be considered a supplementary method to accommodate future growth in combination with other land use strategiesNew State Law allows ADU development as a matter of right in residential zonesHCD has acceptable safe harbor methodologies to determine total ADU potentialHCD has prepared a Guidebook, describing acceptable methodologies and approaches for using ADUs to accommodate RHNA need A. ADU Policy Approaches There are two primary policy approaches that can be employed when using ADUs to accommodate future growth need: Safe Harbor Approach: Based upon a pre-certified methodology, the City can utilize past performance of ADU production and pre-certified percent allocations of units by income category. The current acceptable methodology is shown below: Step One: Determine ADU construction since 2018Step Two: Determine average yearly ADU Construction Rate (2018-2020)Step Three: Assume continued development at the average yearly ADU Construction Rate (as calculated in Step Two) For the City of Newport Beach, application of the above methodology would yield the follow ADU construction since 2018 = 78 unitsAverage yearly ADU construction rate = 25 units/yearAssumed average construction over 8-year planning period= 200 units Housing Element Update Advisory Committee - February 3, 2021 Item No. V(3) - Attachment 3 Approach for Accessory Dwelling Units (ADUs) Page 2 kimley-horn.com 1100 W Town and Country Road, Suite 700 (714) 939-1030 Utilizing the SCAG/HCD approved affordability assumptions discussed in Section B below, the resulting RHNA breakdown by income category for ADUs would be: Income Category Percent Allocation Total ADUs Very Low 25% 50 ADUs Low 43% 86 ADUs Moderate 30% 60 ADUs Above Moderate 7% 4 ADUs TOTAL 200 ADUs Aggressive Approach: A more aggressive approach would identify ADU potential above the safe harbor assumptions. There are a number of considerations with employing this approach, including:  City must be confident/comfortable that the ADU yields can be achievable in the planning period  There should be supplementary policies to support the aggressive approach such as: o Outreach Collateral o ADU Monitoring Program o Amnesty Program o Permit Ready Program o Fee Waivers and Deferrals  Failure to meet ADU targets may result in additional rezoning to accommodate future growth needs B. Affordability Assumptions ADU affordability in Newport Beach can be determined by a variety of methods, including:  Survey of existing ADUs  Review prevailing market rents and apply a per square foot cost basis  Utilization of SCAG / HCD approved methodology (preferred approach) The SCAG / HCD approved methodology was based on a rent survey of ADUs in the County whereby 68% of ADUs are assumed to be affordable to persons with lower incomes. Acceptable affordability percentages pre-certified by HCD, are outlined below: Housing Element Update Advisory Committee - February 3, 2021 Item No. V(3) - Attachment 3 Approach for Accessory Dwelling Units (ADUs) Page 3 kimley-horn.com 1100 W Town and Country Road, Suite 700 (714) 939-1030 C.

El Camino Avenue, Suite 500 Sacramento, CA 95833 (916) 263-2911 / FAX (916) 263-7453 www.hcd.ca.gov August 27, 2020 Sarah Jepson, Director of Planning Southern California Association of Governments 900 Wilshire Blvd., Ste. 1700 Los Angeles, CA 90017 Dear Sarah Jepson: RE: SCAG Pre-certified Local Housing Data and ADU Affordability Analysis Thank you for the opportunity to review the Southern California Association of Governments (SCAG) Pre-certified Local Housing Data. The California Department of Housing and Community Development (HCD) applauds SCAG for its effort to assist local governments in complying with the statutory requirements of Housing Element law. The Local Housing Data prepared for SCAG members will provide an important tool to save costs and time in updating Housing Elements for all local governments in the SCAG region for the 6th Cycle Housing Element. Housing Element law requires a quantification and analysis of existing housing needs. The SCAG Local Housing Data addresses most of the requirements for quantification of existing housing needs,1 including:  Identification of population and employment trends;  Household characteristics (i.e., existing households by tenure, existing extremely low-income households, total, lower and extremely low-income households overpaying, overcrowded households);  Special needs (i.e., number of persons with disabilities, number of persons with developmental disabilities, elderly households by tenure, large households by tenure and female headed households); and  Regional Housing Need Allocation (RHNA) by income group, including extremely low-income households. 1 Local governments must still quantify farmworkers and in some cases, persons experiencing homelessness. Also, some data may require supplemental information such as persons experiencing homelessness, estimates of the number of units in need of rehabilitation and replacement and inventory of units at-risk of conversion to market rate uses. Housing Element Update Advisory Committee - February 3, 2021 Item No. V(3) - Attachment 3 Approach for Accessory Dwelling Units (ADUs) Sarah Jepson, Director of Planning SCAG Pre-certified Local Housing Data and ADU Affordability Analysis Page 2 HCD has reviewed the Local Housing Data and determined it meets statutory requirements for the quantification of existing and projected housing needs as described above. The Local Housing Data will not be subject to further HCD review as part of the Housing Element update process. Further, the Local Housing Data provide a useful and adequate starting point for analysis, however, this initial analysis should be supplemented with discussion of characteristics, trends, resources and unmet needs, as appropriate, to inform policies and programs. For more information on analysis requirements, please see HCD’s Building Blocks at https://www.hcd.ca.gov/community- development/building-blocks/index.shtml. In addition, HCD has reviewed the SCAG Regional Accessory Dwelling Unit Affordability Analysis. Local governments may utilize accessory dwelling units (ADU) to demonstrate adequate sites to accommodate the RHNA. To utilize ADUs, housing elements must include an analysis of the affordability of ADUs, among other requirements. HCD has determined the SCAG Regional ADU Affordability Analysis meets statutory requirements and will not be subject to further HCD review as part of the housing element update.2 However, housing elements must address additional requirements to utilize ADUs toward the RHNA such as ADU development trends, resources and incentives and policies and programs. HCD commends the tremendous efforts SCAG, particularly Kevin Kane, Program Manager, Tom Vo, Senior Regional Planner, and Meg Healy, Assistant Regional Planner, provided in making the data available to assist the preparation and review of housing elements. HCD looks forward to continuing working with SCAG and its members in the update of the housing elements. If you have any questions, please email me at paul.mcdougall@hcd.ca.gov or Tom Brinkhuis at tom.brinkhuis@hcd.ca.gov. Sincerely, Paul McDougall Housing Policy Manager 2 Local jurisdictions may elect to supplement this analysis with additional data or pursue a different approach toward demonstrating the affordability of ADUs which may be subject to further HCD review.

As a result, using trend analysis when estimating the potential for development may not accurately reflect the increased potential for these units. To account for this increased potential, HCD recommends the following options when performing this analysis: Use the trends in ADU construction since January 2018 to estimate new production. This is a conservative option to only account for the effect of the new laws without local promotional efforts or incentives (safe harbor option). Where no other data is available, assume an average increase of five times the previous planning period construction trends prior to 2018. This option is a conservative estimate based upon statewide data on ADU development since the implementation of the new laws (safe harbor option). Use trends from regional production of ADUs. Include programs that aggressively promote and incentivize ADU and JADU construction. Other analysis (reviewed on a case-by-case basis). Potential affordability of these units must still be calculated per the analysis outlined on the previous page. In addition to the above options, the element should also include a monitoring program that a) tracks ADU and JADU creation and affordability levels, and b) commits to a review at the planning cycle mid-point to evaluate if production estimates are being achieved. Depending on the finding of that review, amendments to the housing element may be necessary, including rezoning pursuant to Government Code 65583.2 (h)and (i).End ADU explanation Alternative Adequate sites: Under limited circumstances, a local government may credit up to 25 percent of their adequate sites requirement per income category through existing units that will be: - substantially rehabilitated - in a multifamily rental or ownership housing complex of three or more units that are converted from non affordable to affordable rental - preserved at levels affordable to low- or very low-income households, where the local government has provided those units with committed assistance For more information on this option, please refer to HCD’s Building Blocks Webpage Manufactured housing, manufactured housing park hook-ups, floating homes/live aboard berths: In certain circumstances a jurisdiction can utilize the potential for new manufactured housing either in a manufactured housing park or on large properties in rural areas, or new floating home/liveaboard berths with sewer and water hook ups. In cases of a manufactured home park or in floating home/liveaboard berth marinas, the jurisdiction may count new spaces with infrastructure hook-ups intended for permanent residential occupancy and reported to the Department of Finance. Potential for manufactured homes in rural areas should be analyzed using the same factors as those Housing Element Update Advisory Committee - February 3, 2021 Item No. V(3) - Attachment 3 Approach for Accessory Dwelling Units (ADUs)
