Los Angeles Rent Control Rules
Los Angeles has one of the oldest and most comprehensive rent control systems in California. The Rent Stabilization Ordinance (RSO) covers approximately 650,000 units across the city — primarily buildings with two or more units built before October 1, 1978.
The RSO annual allowable increase for 2026 is 3.0%, set by the LA Housing Department. This is significantly lower than the statewide AB 1482 cap of 8.7%. RSO-covered landlords must register with LAHD and pay an annual registration fee per unit.
Properties not covered by the RSO — including newer buildings, single-family homes, and condos — may still be subject to AB 1482. In those cases, the statewide cap of 8.7% (5% + 3.7% CPI) applies instead.

- Properties exempt from both RSO and AB 1482 include units built within the last 15 years and owner-occupied duplexes
Frequently Asked Questions
What is the difference between the RSO and AB 1482 in Los Angeles?
The RSO is Los Angeles’s local rent control ordinance covering buildings with 2+ units built before October 1, 1978. It caps annual increases at 3.0% for 2026. AB 1482 is the statewide law that caps increases at 8.7% (5% + 3.7% CPI). If your property is RSO-covered, the stricter RSO cap applies. If not, AB 1482 applies instead.
How do I know if my LA property is covered by the RSO?
The RSO covers most residential buildings in the City of Los Angeles with 2 or more units that received a certificate of occupancy before October 1, 1978. You can check your property’s status on the LAHD ZIMAS system or by contacting the LA Housing Department directly. Condos, single-family homes, and newer buildings are generally not covered.
Can I raise rent more than 3% on an RSO unit in Los Angeles?
Generally no. The 3.0% is the maximum Annual General Adjustment for 2026. However, landlords may petition LAHD for an additional increase based on capital improvements, increased operating expenses, or other grounds. Banking (carrying over unused increases) is allowed under certain conditions. Consult LAHD or an attorney for details on these exceptions.
