YIMBY Law first filed suit in 2019 against Simi Valley, CA when the City Council turned down a proposed 108-unit residential care facility for seniors with 68 assisted living units and 40 memory care units. The City Council claimed that the project did not qualify as housing under California’s Housing Accountability Act. We disagreed, arguing that homes do not need individual kitchens to be considered housing; the court officially sided with us on May 17th, 2021.

Since then we have filed and won nine additional lawsuits. The lawsuits listed here are active.

On February 13, 2025, YIMBY Law along with Californians for Homeownership sued the City of Los Angeles for failing to complete its required rezoning as outlined in its certified housing element.

The project at 450 O’Farrell Street is a 316-room group housing project in the Tenderloin neighborhood of San Francisco, a redevelopment of a church’s property, that includes 48 on-site below market rate homes. The City is violating a number of laws in having disapproved this project: the Housing Accountability Act, the Housing Crisis Act of 2019 (SB-330) and the Permit Streamlining Act.
The court agreed that the city broke state housing law in this case, and we are continuing to argue that this is an example of the city’s pattern of illegally delaying and denying homes from being approved. Read more.
469 Stevenson is a proposed 495-unit project that would replace a department store valet parking lot in San Francisco’s Theater District with a 27-story residential building that includes 73 on-site below market rate and 45 off-site below market rate homes.
The Superior Court ruled the city did not violate state housing law regarding the project, but we are continuing to argue our claim that San Francisco is demonstrating a pattern of illegally delaying and denying housing projects including the one at 469 Stevenson. We reserve the right to appeal the decision about the project while we litigate this issue. Read more.
On March 8. 2023, YIMBY Law sued the city of Sausalito, California following the city’s adoption and self certification of a housing element we believe is noncompliant with state law. The main issues are that Sausalito did not do an Environmental Impact Report for their Housing Element, which is a CEQA violation, and their site inventory contains too many unrealistic sites.

YIMBY Law petitioned for court intervention against the City of Redondo Beach on 8/4/2023. The City has passed policies and procedures that subverted the Permit Streamlining Act and the Housing Crisis Act, ignored laws concerning express permitting of low-income housing developments, and denied housing applicants their vesting rights.

Winning lawsuits means more homes are built for people.

Achieving compliance with new pro-housing laws is dependent upon the existence of enforcement mechanisms, something that has only developed in recent years due to YIMBY organizing and support.

Years of housing law neglect and obstructionist behavior (NIMBYism) have taken a toll on housing production and have caused housing shortages for people at all income levels in communities across the United States.

YIMBY Action chapters and members, state and local lawmakers, and pro-housing community organizations advocate for housing laws to address the housing shortage and strengthen compliance. These laws provide clear accountability measures and guidelines for cities to follow so that more homes are built and more people are housed.

The critical next step to achieving housing for all is to ensure these guidelines are followed. Cities and counties now have a job to do and YIMBY Law is here to make sure they do it.
