California Assembly Bill 1123 on Accessory Dwelling Units and Housing Supply in Culver City

California Assembly Bill 1123, approved by the state legislature in June, updates standards for accessory dwelling units on single-family and multifamily properties. The changes apply directly to Culver City homeowners seeking permits and to renters looking for additional housing options in the city.

The bill comes as Culver City continues to address its share of regional housing needs under existing state requirements. Local planning staff have noted increased inquiries about unit conversions in recent months, particularly in areas near the Expo Line stations and along Washington Boulevard.

Effects on residents

Culver City residents who own single-family homes may now pursue larger or more flexible accessory units without some prior size restrictions. This adjustment could allow families to add living space for relatives or generate rental income. Renters in the city stand to gain from potential new units priced below market rates in established neighborhoods such as the Artist District and Culver Crest.

Property owners planning projects must still meet Culver City building codes and obtain approvals from the city's planning division. The legislation does not override local design guidelines or parking requirements that remain in place.

Budget and next steps

According to the U.S. Census Bureau, Culver City recorded a population of 40,654 in 2020. The legislation states that local governments must update their permitting timelines to align with the new state standards within six months. City staff have begun reviewing current application processes in preparation for the required adjustments.

Implementation begins in January 2027. Culver City officials expect to release updated guidance documents for residents by October. The measure applies only to new applications filed after the effective date.
