2025 URBAN WATER MANAGEMENT PLAN <br /> MAY 2026/FINAL DRAFT/CAROLLO <br /> 2021-2029 Housing Element provides an eight-year strategy to ensure the availability of adequate <br /> residential sites to accommodate these units. <br /> ■ Accessory Dwelling Units:ADUs are separate small dwellings embedded within residential <br /> properties.There has been an increase in the construction of ADUs in California in response to the rise <br /> in interest in providing affordable housing supply. Since 2020, several landmark laws were passed by <br /> the State Legislature, updating ADU law to simplify the construction, rental, and sale of ADUs in <br /> California.The most significant laws that have recently come into effect include: <br /> AB-1033 Accessory dwelling units: local ordinances: separate sale or conveyance,which authorizes <br /> local governments to adopt ordinances permitting the sale of ADUs separately from the primary <br /> residence as condominiums. <br /> AB-976 Accessory dwelling units: owner-occupancy requirements,which prohibits a local agency <br /> from requiring owner-occupancy for property owners to build and rent an ADU. <br /> A13-1154 Junior accessory dwelling units,which no longer requires owner-occupancy for Junior <br /> ADUs (JADU) as long as they have their own bathroom. <br /> AB-1332 Accessory dwelling units: preapproved plans, which requires local agencies to develop a <br /> program for pre-approved ADU plans, with projects using these plans having to be approved or <br /> denied within 30 days. <br /> SB-543 Accessory dwelling units and junior accessory dwelling units, which requires local agencies <br /> to determine if an ADU/JADU application is complete within 15 business days of submittal, revises <br /> ADU size to now be measured by "interior livable space" and now re-defines a JADU to be no <br /> more than 500 square feet of interior livable space. <br /> >> SB-1211 Land use: accessory dwelling units: ministerial approval, which authorizes multi-family <br /> property owners to build up to eight detached ADUs on a single lot, provided that the number of <br /> ADUs does not exceed the number of existing primary units. <br /> AB-2S33 Accessory dwelling units:junior accessory dwelling units: unpermitted developments, <br /> which prohibits local agencies from denying permits for unpermitted ADUs/JADUs constructed <br /> before January 1, 2020, based on code violations unless the structure is a health or safety hazard. <br /> In 2024, a total of 6,162 new residential units were permitted in Orange County, including those for ADUs <br /> (CDR, 2025). CDR projects that by 2050, approximately 13,000 more ADUs will be built in Orange County, <br /> with 2,028 ADUs expected within the City's service area. The increase in ADUs is likely to result in an <br /> increase in number of people per lot of land dwelling unit. Depending on whether the addition of ADUs <br /> results in a net replacement of irrigated area (or other high water use features such as swimming pools), <br /> ADUs could increase or decrease water demands. <br /> CITY OF SANTA ANA <br />
