Rental regulatory context (informational only — not legal advice):
California AB 1482 (Tenant Protection Act, Civ. Code § 1947.12) caps annual rent increases at 5% + local CPI (max 10%) on covered properties. In Richmond: Richmond Fair Rent, Just Cause for Eviction, and Homeowner Protection Ordinance — annual cap of 60% of CPI or 3.0% (whichever is lower) for covered pre-1995 units.
