Rent Stabilization Ordinance


Los Angeles Housing Department


The purpose of the Rent Stabilization Ordinance (RSO) is to protect tenants from rent increases.

Residential rental units covered by the RSO include:

Town homes
Two or more dwelling units on the same lot
Mobile homes
Mobile home pads
Rooms in a hotel, motel, rooming house or boarding house occupied by the same tenant for 30 or more consecutive days

To be subject to the RSO of the City of Los Angeles, a property must meet the following three criteria:

The property must be within the City of Los Angeles; and
There must be two or more units on the lot; and
The building must have a Certificate of Occupancy issued on or before October 1, 1978. (In the case of mobile homes and mobile home pads, the park must have been issued a permit to operate before February 10, 1986).

Properties exempt from the RSO are as follows:

Properties located in other municipalities or within unincorporated areas within the County of Los Angeles;
Single family dwellings, used as such;
Properties (except mobile homes and mobile home pads) with a Certificate of Occupancy issued after October 1, 1978 (new construction);
Mobile homes or mobile home pads when the park was issued a permit to operate after February 10, 1986;
Government owned properties;
Units occupied by an owner or family member where no rents are collected;
