Learn more about our legislative work

Casita-supported and sponsored bills launched the Accessory Dwelling Unit (ADU)  revolution and continue to enhance ADU/JADU and middle housing-related state law annually. Our legislative successes catalyzed the  growth of ADUs as the fastest growing housing type in California, with more than 113,000 ADUs permitted since 2017. Our legislative momentum would not be possible without our extended community of  members, supporters, and ecosystem partners. We continue to rely on and appreciate your support letters, petition signatures, and network sharing of our calls to action.

Our 2024 ADU and Middle Housing Legislation

Casita Coalition is proud to support California legislation to advance ADU and middle housing solutions. We’re excited to announce that all three bills have passed both their houses and are on the Governor’s desk awaiting signature! Thanks to everyone for your help.

SB 1211 (Skinner) Multifamily ADUs—UPDATE: Signed Into Law!

SB 1211 Improves flexibility for ADU type and location of ADUs on multifamily properties so the existing site cap allowances can be workable for more properties.

AB 2533 (Carrillo) Unpermitted ADU Amnesty—UPDATE: Signed Into Law!

AB 2533 makes improvements to existing unpermitted ADU amensty laws, helping to preserve existing informal ADU rentals and the important role they play for homeowners while ensuring the safety of tenants. The bill specifies the code standards local agencies must use to assess safety, cuts fees and charges for lower resourced homeowners, and requires cities to provide a checklist of standards that units will have to meet, upfront.

SB 1077 (Blakespear) ADUs in the Coastal Zone—UPDATE: Signed Into Law

SB 1077 was designed to responsibly exempt ADUs and JADUs on qualified sites from the additional permitting requirements and cost of Coastal Development Permits, reducing the time and cost burdens for homeowners willing to add long term more affordable ADU homes to their properties. The bill was amended during the legislative process and in its current form has passed both houses. The bill now requires the California Coastal Commission to conduct a hearing and develop a guidance document for local jurisdictions to use in drafting the ADU elements of their Local Coastal Plan. Importantly, it requires the coastal commission to work with HCD to develop that guidance document, improving inter-agency coordination on ADU policy.

Thank you for helping us protect our collective housing policy wins

Casita Coalition monitors the legislative and regulatory landscapes for both opportunities and threats, and we have had to rapidly and effectively address and eliminate significant threats to middle housing progress on several occasions. Two examples below:

State-exempt ADU law interpretation: We took action to reinforce the legislative intent that established the ‘by-right’ state exempt category. If unchallenged, this would have set back CA ADU law by many years and decimated the factory-built ADU industry

SB 1055 (Min) undermined state ADU law that protects homeowner rights

• This bill proposed a dangerous precedent by 'rewarding' cities and counties that have met their Regional Housing Needs Allocation goals for the year for affordable housing by allowing them to reduce the height standards of attached ADUs to 16', below current state law, and shorter than the home the ADU is attached to in some cases

• It would create a confusing patchwork of standards that would change each year, reducing ADU production and disproportionately burdening lower resourced homeowners and builders

• Current ADU height standards are reasonable and based on local zoning for the property--and make ADUs above garages possible when attached to 2-story homes

ADU policy wins have permitted more than 113,000 ADU homes over the last seven years. Your collective action has kept these attainable homes possible for Californians.
