Rent control rules in Altadena, CA — also known as rent stabilization or rent cap ordinances — limit annual rent increases and protect tenants from displacement.
The LA County Rent Stabilization & Tenant Protections Ordinance (RSTPO) caps annual rent increases in covered Altadena multi-unit buildings (built before Feb 1, 1995) at 3% or 60% of CPI, whichever is lower (effective 2025).
The LA County RSTPO (Title 8, Chapter 8.52 and related provisions) covers all rental units in unincorporated LA County (including Altadena) in multi-unit residential properties with certificates of occupancy issued before February 1, 1995. As of January 1, 2025, the allowable annual rent increase is the lesser of 3% or 60% of the regional CPI. Small landlords (≤4 units) who certify compliance may add 1%. Designated 'luxury units' may increase up to 5%. Single-family homes and condos are generally exempt unless owned by a corporate landlord (per AB 1482 statewide rules). The ordinance is administered by LA County Department of Consumer & Business Affairs.
Excess rent increases must be refunded. Tenants may file complaints with DCBA; civil penalties up to $10,000 per violation under the ordinance.
