Is my apartment rent controlled in Los Angeles?
Los Angeles rent control is the Rent Stabilization Ordinance, or RSO. As a rule it covers rental units in the City of Los Angeles in buildings of two or more units with a certificate of occupancy issued on or before October 1, 1978. Two things trip people up: the City of Los Angeles is not Los Angeles County, and a building that misses the RSO date can still be covered by other law.
1. Confirm you are in the City of Los Angeles
The RSO is a City ordinance. Unincorporated Los Angeles County has its own separate rent rules, and neighbouring cities such as Santa Monica and West Hollywood have theirs. A Los Angeles mailing address is not proof you are inside the City limits — the parcel is what decides it.
2. Check the date and the unit count
The core test is build date plus unit count. Beyond ordinary apartment buildings, LAHD describes the RSO as reaching condominiums, duplexes, accessory dwelling units, and rooms occupied by the same tenant for 30 or more consecutive days in a hotel or rooming house. A lone single-family house on its own parcel is generally outside the RSO — but two or more dwellings on the same parcel can be inside it.
3. Check LAHD's records
Owners of RSO units must register them with the Los Angeles Housing Department and pay an annual fee, so LAHD holds a registration record for covered units. Asking LAHD whether your unit has one is the closest thing to a definitive answer available to a tenant. The certificate of occupancy itself is a LADBS record.
4. What our Los Angeles map shows — and what it does not
This caveat is important enough to state before the map link, not after it. The Find A Crib Los Angeles layer is derived, not official: it flags buildings that meet the RSO's published criteria — build year and unit count, from county assessor data — and labels them "likely RSO". It is not LAHD's list. A building can meet those criteria and still be exempt, and a building can be covered for a reason the assessor record does not show. Use it to narrow the question down, then confirm with LAHD before you act on it.

- AB 1482, the California statewide rent cap, limits annual increases for many units outside local rent control. The limit is tied to regional CPI and changes annually — check the current figure at LAHD's AB 1482 page.
- The City's Just Cause Ordinance extends eviction protections to many non-RSO rentals once the tenancy has passed an initial qualifying period, so "my building is too new for the RSO" does not mean you can be evicted without a reason.
