Directory
LA County independent cities
Cities in Los Angeles County that are not part of the City of Los Angeles. Each has its own building department, its own ADU ordinance, and its own permit submittal process.
Permit pathways vary by city. State law (CA Gov Code §65852.2) sets the floor on what every city must allow, but each city overlays its own rules on top. The per-city pages show the local agency contact, ordinance specifics, and any overlays that hit a meaningful share of lots.
