Los Angeles Rent Increase Rules: A Practical Guide for Rental Owners

Last reviewed: July 11, 2026

The first question an owner should ask before increasing rent is not, “How much can I raise it?”

It is, “Which law governs this particular unit?”

A Los Angeles mailing address does not necessarily mean the property is in the City of Los Angeles. A property may sit in another incorporated city or in an unincorporated part of Los Angeles County. Even within the City of LA, one unit may be covered by the Rent Stabilization Ordinance while another property is governed by the Just Cause Ordinance and California’s statewide rent cap.

Using the wrong jurisdiction can invalidate an otherwise straightforward increase.

Step one: identify the exact jurisdiction

Confirm whether the property is located in:

• The City of Los Angeles

• Another incorporated city, such as Santa Monica, West Hollywood, Pasadena, Inglewood, or Long Beach

• Unincorporated Los Angeles County

Many incorporated cities have their own rules. The Los Angeles County Department of Consumer and Business Affairs specifically advises owners to check with the relevant city because its county rent-stabilization ordinance applies to unincorporated areas, not every property in LA County.

After confirming the jurisdiction, determine whether a local ordinance applies to the unit. Only then should the owner calculate the state limit.

City of Los Angeles RSO properties

The City of Los Angeles Rent Stabilization Ordinance generally covers rental properties built on or before October 1, 1978, along with certain replacement units. Property type, parcel configuration, and construction history can affect the result. LAHD’s property-search resources and ZIMAS can indicate whether at least one unit at an address is subject to the RSO, although owners should investigate further when a parcel contains mixed coverage.

Current RSO annual increase

The allowable annual RSO increase is 3% from July 1, 2026, through June 30, 2027. RSO annual increases are generally permitted once every 12 months.

The City changed the underlying formula effective February 2, 2026. Future increases are based on 90% of the average CPI, with a 1% floor and 4% ceiling. The current 3% figure remains in place through June 30, 2027. The City also removed the former additional percentage for utilities from the annual RSO adjustment.

A lawful increase still requires the correct base rent, enough time since the prior increase, a valid written notice, proper service, and current property registration where required.

California’s statewide Tenant Protection Act

When a stricter local rent cap does not apply, California’s Tenant Protection Act—often called AB 1482—may limit the increase.

For covered housing, the general formula is 5% plus the applicable change in the cost of living, or 10%, whichever is lower, over a 12-month period.

For the Los Angeles metropolitan area:

• 8.0% applies to increases effective from August 1, 2025, through July 31, 2026.

• 8.7% applies to increases effective from August 1, 2026, through July 31, 2027.

Because this article was reviewed on July 11, 2026, an increase taking effect before August 1 and one taking effect on or after August 1 may be subject to different percentages.

Not every property is covered by AB 1482

Common exemptions can include housing constructed within the previous 15 years, certain affordable housing, owner-occupied duplexes, and some single-family homes or condominiums. The single-family and condominium exemption depends on ownership structure and the owner providing the required exemption notice.

An owner should never assume that “single-family home” automatically means exempt. California Courts notes that some single-family homes and condos qualify only when the ownership and notice requirements are satisfied.

Unincorporated Los Angeles County

The Los Angeles County Rent Stabilization and Tenant Protections Ordinance applies to eligible properties in unincorporated LA County.

For July 1, 2026, through June 30, 2027, the maximum annual increases for fully covered units are:

• 1.919% for general rent-stabilized units

• 2.919% for qualifying, certified small property landlords

• 3.919% for qualifying luxury units

Small property landlords must submit the required annual certification and include the required disclosure in the tenant’s rent-increase notice. Luxury-unit owners also have a disclosure requirement.

These percentages should not be used for properties located inside the City of Los Angeles or another incorporated city.

How much notice is required?

California generally requires:

• 30 days’ written notice when the total increase is 10% or less

• 90 days’ written notice when the total increase is more than 10%

A fixed-term lease generally cannot be increased before the term expires unless the lease permits it.

The notice period is only one part of a valid increase. The document must identify the proper parties and rental unit, state the new rent and effective date, and be served using a legally permitted method. Local notices, disclosures, registration requirements, or language rules may also apply.

Three examples using a $2,500 monthly rent

These examples illustrate the arithmetic only. They do not establish that a particular property qualifies for an increase.

City of Los Angeles RSO unit

At 3%:

• Increase: $75

• New monthly rent: $2,575

The increase would still need to comply with the once-per-12-month rule and all notice and registration requirements.

AB 1482-covered unit after August 1, 2026

At 8.7%:

• Increase: $217.50

• New monthly rent: $2,717.50

A lower local cap would control when applicable.

General fully covered unit in unincorporated LA County

At 1.919%:

• Increase: approximately $47.98

• New monthly rent: approximately $2,547.98

The owner should confirm the exact calculation and whether the unit is fully covered.

Common rent-increase mistakes

Using the mailing address instead of the jurisdiction

“Los Angeles” may appear in an address even when the property is not governed by the City of Los Angeles.

Applying the state cap to a locally controlled unit

The 8.7% state cap is not permission to increase every LA rent by 8.7%. A City RSO or County RSTPO unit may have a much lower limit.

Stacking local and state percentages

An owner does not add a local percentage to the AB 1482 percentage. The applicable limit must be determined from the property’s coverage.

Relying on an exemption that was never documented

Some exemptions depend on both ownership structure and specific language delivered to the tenant.

Using the market rent as the starting point

An occupied unit’s increase is generally calculated from its lawful current rent and increase history, not the amount a vacant unit might command.

Serving an old form

Rent caps, local disclosures, and notice requirements change. Reusing a notice from a prior year without reviewing it can be costly.

Frequently asked questions

Is every Los Angeles rental subject to rent control?

No. Coverage depends on the exact jurisdiction, construction date, property type, ownership, applicable notices, and other factors.

Is the City of LA Just Cause Ordinance a rent-control law?

The JCO primarily regulates reasons for ending a tenancy rather than setting an annual local rent cap. A JCO unit may still be subject to AB 1482’s statewide rent limit.

Can an owner use both the 3% RSO increase and the 8.7% state increase?

No. The state percentage is not added to the local RSO allowance.

Can rent be raised during a fixed-term lease?

Usually not until the term ends unless the lease expressly allows an increase and the increase is otherwise lawful.

Can unused RSO increases be saved and added later?

The current LAHD RSO bulletin describes the annual adjustment as noncumulative and nonretroactive. An owner should not assume that skipped increases can be stacked later.

Where should an owner start?

Start with the property address, parcel and construction records, current lease, rent ledger, prior notices, and any exemption language. Determine coverage before calculating the new rent.

Verify before serving the notice

A rent increase is one of the clearest examples of why Greater LA property management must be property-specific. Two homes a few blocks apart may be governed by materially different rules.
