Where the answers come from

Four public records, each from the agency that keeps it. Each one shows when we last checked it.

• LA Housing Department

  Rent stabilization inventory

  Which properties the Rent Stabilization Ordinance covers. This decides most answers on the site.

Rent caps, deadlines and dollar amounts come from the Los Angeles Municipal Code, the Housing Department and California law. Each figure shows the date it was last checked on the page that uses it, and a figure nobody has checked is not shown. More on how every figure is verified.

How an answer is reached

1. 1

   Your address

   We find it in the City of Los Angeles address list and pin its exact location.

2. 2

   City boundary check

   We check that location against the official city boundary. Outside the City of Los Angeles we say so and stop: other cities write their own rules.

3. 3

   LAHD list and county record

   We look the parcel up on the Housing Department's rent stabilization list, and read its year built and unit count from the county assessor.

4. 4

   A plain-language answer

   The verdict comes first. Under it, "How we know this" names the records behind it and says whether it is confirmed or preliminary.

Confirmed or preliminary, and we always say which

Confirmed

The property is on the Housing Department's rent stabilization list, or the official boundary puts the address outside the city. That is the record itself, so the answer carries no caveat.

Preliminary

The property is not on the list, so we apply the ordinance's own test to the county's record: completed on or before October 1, 1978, with two or more units. Every answer reached this way is labeled preliminary and comes with a way to check it yourself.

Cannot tell

When we cannot find the building's age or unit count, or cannot confirm which city the address is in, we say that instead of guessing.

Not being on the list does not prove a unit is uncovered. Buildings drop off it for clerical reasons, and a landlord who never registered has not escaped the ordinance.

Where the records fall short

• The Housing Department publishes its list once a year. The edition we use is dated April 28, 2026, so a building registered since then is not on it yet.
• The county records each condominium as its own one-unit parcel. For a condo that is not on the list, our preliminary answer can say the building fails the test when it does not. That is the answer most worth checking.
• Parcel records come from the county's 2024 assessment roll. A building finished or converted since then may be missing or out of date.
