Los Angeles County does not have one rent rule for every address. The City of Los Angeles has its own RSO. Other incorporated cities may have their own ordinances. This guide is for eligible properties in unincorporated Los Angeles County that fall under the County Rent Stabilization and Tenant Protections Ordinance or its related mobilehome program.
Enter the property address in the Los Angeles County Rent Stabilization Program and Rent Registry. Confirm that the property is in an unincorporated area and that the unit is covered. A mailing address that includes “Los Angeles” does not prove that the City of Los Angeles RSO or the County RSTPO applies.
For the July 1, 2026, through June 30, 2027 period, the County publishes three ceilings for rent-stabilized units. The amounts below are the County table, not a substitute for a property-specific coverage and category decision. See the current DCBA Rent Stabilization Program page.
| County category | Maximum listed increase | Effective period | Control before notice |
|---|---|---|---|
| General covered unit | 1.919% | July 1, 2026 through June 30, 2027 | Confirm RSTPO coverage and registration. |
| Qualifying small-property landlord | 2.919% | July 1, 2026 through June 30, 2027 | Annual self-certification and notice disclosure are required. |
| Qualifying luxury unit | 3.919% | July 1, 2026 through June 30, 2027 | The notice must state that the unit meets the luxury-unit requirements. |
Do not choose the higher small-property or luxury ceiling because it produces a better budget result. If the category is not documented, treat the category as unresolved and stop the notice package.
The County program uses the Rent Registry to register units, update unit information, pay required annual fees, and verify coverage. Save the registration status and any exemption or category documentation in the property file before serving the notice.
County rules can require more than the statewide notice period. Apply the California timing and service rules in the California notice and service guide, then add the County disclosures and forms that apply to the unit. Keep the notice, proof of service, registration evidence, and first affected ledger entry together.
An eligible unit subject to the County RSTPO does not receive the statewide Los Angeles Area percentage on top of the County ceiling. The stricter local rule controls. The California 2026–2027 cap guide is useful for comparison, but the County table controls a covered unincorporated County unit.
Assume the County category is a general covered unit and the amount that the County rules allow you to use as the base is $2,000. A simple illustration of 1.919% is $2,000 × 1.01919 = $2,038.38. The actual base, rounding, prior increases, rent components, and any approved pass-throughs must follow the County rules and the property file. Keep pass-through items separate from rent when the program requires that treatment.
No. The City of Los Angeles has its own RSO. Use the property address and the responsible local agency to choose the rule.
No. The County requires an annual self-certification and a disclosure in the rent-increase notice. Confirm the category before using the higher ceiling.
Not as an assumption. Some pass-throughs or approved charges are treated separately and may require prior County approval. Keep them separate and verify the current program instructions.
