CA SB12

Requires cities and counties with residential structures in very high fire risk areas to amend their general plans (upon housing element revision after July 1, 2024) to include wildfire risk reduction strategies, location of fire risk areas, and implementation measures.

Mandates adoption of wildfire risk reduction standards by the State Fire Marshal by January 1, 2023, for residential developments in very high fire risk areas, with differentiated requirements based on development size (9+ units and 100+ units have stricter standards).

Prohibits cities and counties from approving development agreements, discretionary permits, or subdivision maps for residential projects in very high fire risk areas unless findings are made that projects comply with wildfire risk reduction standards.

Requires regional housing needs allocation plans (for seventh and subsequent revisions) to allocate lower proportions of housing to jurisdictions where lands within very high fire risk areas would otherwise be needed as adequate sites.

Establishes the Wildfire Risk Reduction Planning Support Grants Program providing $250,000-$350,000 grants to small jurisdictions to support planning activities necessary to implement the bill's requirements.
