The City of Santa Ana has adopted Zoning Ordinance Amendment No. 2024-03, updating Article II (Use Districts) of Chapter 41 to align local Accessory Dwelling Unit (ADU) regulations with state law. This amendment ensures compliance with Senate Bill 1211, which took effect on January 1, 2025. The ordinance modifies zoning rules to permit ADUs and Junior ADUs (JADUs) citywide, specifying allowable locations, development standards, and exemptions from parking and setback requirements under certain conditions. Additionally, the ordinance introduces revised definitions and procedural updates to facilitate ADU approvals. These changes promote housing diversity and streamline ADU development to address California's housing crisis.

Why it Matters

This ordinance makes it easier for homeowners and developers to construct ADUs in compliance with state law, expanding housing options in Santa Ana. By reducing barriers such as parking and lot size requirements, it facilitates more affordable housing solutions and urban density management.
