Local rent control can be stricter

Plain language

Cities like Los Angeles, San Francisco, Oakland, Berkeley, and Santa Monica have their own rent-control ordinances with far lower caps than AB 1482 (sometimes 1–4%). Where a local ordinance applies, it controls.

Statute text

AB 1482 is a statewide floor of protection, but many cities have stronger local rent-stabilization ordinances. For example, annual allowable increases in places like Oakland or Berkeley can be around 1% in a given year — far below the AB 1482 cap. Local ordinances may also have their own just-cause and registration rules. Always check the specific city's rent board for the unit's location; the stricter of state or local law applies.
