LA Rent Stabilization (RSO) Checker

The Los Angeles Rent Stabilization Ordinance (RSO) covers approximately 624,000 rental units in the City of Los Angeles. Buildings with two or more units that were built before October 1, 1978 and have a certificate of occupancy are generally covered. Some exemptions apply, including single-family homes, condominiums, and newer construction.

If your apartment is covered by the RSO, your landlord can only increase rent by the annual percentage set by the LA Housing Department (LAHD), typically 3–8%. You also have just-cause eviction protections — your landlord cannot evict you without a legally recognized reason, and relocation assistance may be required for no-fault evictions.

Search your building's address above to instantly check RSO status based on public records. You can verify your building’s RSO status through the LAHD’s ZIMAS lookup tool or by contacting LAHD directly. The data on this page reflects public records from the City of Los Angeles.

LA's Housing Department sets annual RSO rent increase limits based on the Consumer Price Index (CPI). As of recent rulings, increases are capped at 3-8% per year. The exact rate depends on the year and any additional utility pass-throughs.

RSO tenants can file a complaint with the LA Housing Department if their landlord raises rent above the allowed amount. You may be entitled to a rent reduction and repayment of overcharges.
