California AB 1482 (Tenant Protection Act, Civ. Code § 1947.12) caps annual rent increases at 5% + local CPI (max 10%) on covered properties. In San Francisco: San Francisco Rent Ordinance (Admin. Code Ch. 37) — annual allowable increase is 60% of Bay Area CPI (capped at 7%) for covered pre-June 1979 buildings. Official program rules ↗
