Los Angeles County Rent Increase Notice Guide for 2026–2027

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.

Confirm the boundary before using a county cap

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.

2026–2027 Los Angeles County limits

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.

Use the category that the file supports

• General covered unit: Use the general ceiling unless the file supports another County category.
• Small-property landlord: Confirm the annual self-certification and include the required disclosure in the rent-increase notice.
• Luxury unit: Confirm the County definition and include the required luxury-unit disclosure in the notice.

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.

Registration, fees, and notice controls

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.

Do not stack County and statewide caps

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.

Calculation illustration

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.

Before the County notice is served

1. Confirm incorporated versus unincorporated location.
2. Confirm RSTPO or mobilehome program coverage in the County registry.
3. Confirm the applicable category and keep the self-certification or luxury documentation.
4. Confirm the effective period and maximum ceiling.
5. Review the County notice disclosure and current form set.
6. Apply the state notice period and mailing extension that fit the proposed increase.
7. Save proof of service, registration, and any County submission.
8. Update the ledger only on the lawful effective date and assign a second reviewer.

Frequently asked questions

Does the County RSTPO apply to the City of Los Angeles?

No. The City of Los Angeles has its own RSO. Use the property address and the responsible local agency to choose the rule.

Can a small-property landlord use 2.919% automatically?

No. The County requires an annual self-certification and a disclosure in the rent-increase notice. Confirm the category before using the higher ceiling.

Can a County owner add a separate fee to the rent increase?

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.
