If you own rental property in Los Angeles County, figuring out how much you can legally raise the rent is not always straightforward. Depending on where your property is located, when it was built, and whether it qualifies for certain exemptions, the allowable increase can vary significantly.

For landlords with fully covered rental properties in unincorporated Los Angeles County, the LA County rent increase limit for 2026–2027 is generally 1.919%. However, qualifying small property landlords may increase rent by up to 2.919%, while certain luxury rental units qualify for a 3.919% increase.

These percentages are effective from July 1, 2026, through June 30, 2027, under the Los Angeles County Rent Stabilization and Tenant Protections Ordinance (RSTPO).

Before sending a rent increase notice, landlords need to understand more than just the percentages. Property coverage, registration requirements, annual self-certification, and notice procedures can all affect whether an increase is permitted.

This guide explains the current Los Angeles County rent increase rules, how to determine which percentage applies to your property, and what landlords should review before adjusting their rental rates.

Key Takeaways

• The standard rent increase is 1.919%. This applies to most fully covered rent-stabilized units in unincorporated Los Angeles County from July 1, 2026, through June 30, 2027.
• Small property landlords may qualify for 2.919%. Eligible owners must complete annual self-certification with the County and provide the required disclosure.
• Certain luxury units qualify for 3.919%. The property must meet specific bedroom, building-size, and historical rent requirements.
• LA County and LA City have different rent control laws. The City of Los Angeles RSO allows a standard 3% annual increase during the same period.
• Landlords generally must wait 12 months between annual increases. Proper written notice and applicable disclosures are also required.
• Registration matters. Landlords should confirm that their properties are properly registered and required fees are current before increasing rent.

What Is the LA County Rent Increase Limit for 2026–2027?

Los Angeles County has established three allowable annual rent increase percentages for fully covered residential rental units under its RSTPO.

The applicable percentage depends on the property’s classification and whether the landlord meets additional eligibility requirements.

OFFICIAL RSTPO RATES · JULY 1, 2026 TO JUNE 30, 2027

1.919%

General units

2.919%

Small property landlords

3.919%

Luxury units

Source: Los Angeles County Department of Consumer and Business Affairs, 2026–2027 RSTPO Rent Increase Bulletin.

For example, a landlord collecting $2,000 per month from a fully covered unit subject to the general limit could increase the monthly rent by approximately $38.38, bringing it to $2,038.38.

A qualifying small property landlord with the same rental amount could potentially increase the rent to $2,058.38.

While these differences might appear small on an individual unit, they can add up over time, especially for owners managing multiple rental properties.

How Does LA County Calculate Its Annual Rent Increase Limits?

Beginning January 1, 2025, Los Angeles County implemented a formula that ties allowable annual rent increases to changes in the Consumer Price Index (CPI).

Under this formula, the general allowable increase equals 60% of the applicable annual CPI change, with a maximum of 3%.

Qualifying small property landlords may add one percentage point, subject to an overall 4% limit. Qualifying luxury units may receive an additional two percentage points, subject to an overall 5% limit.

These maximum ceilings do not mean landlords can automatically raise rents by 3%, 4%, or 5% every year. The County calculates and publishes the actual allowable percentages for each annual period.

For July 2026 through June 2027, those published percentages are 1.919%, 2.919%, and 3.919%, respectively.

How Do the 2026–2027 Limits Compare With Last Year?

The current rent increase limits are slightly lower than those established for the previous annual period.

Period	General units	Small landlords	Luxury units
July 2025 to June 2026	1.930%	2.930%	3.930%
July 2026 to June 2027	1.919%	2.919%	3.919%

Although the difference is minimal, landlords should always use the percentage applicable to the effective date of the proposed increase.

Using an outdated percentage could result in a rent increase that exceeds the allowable limit, even if the difference is only a few dollars.

Which Rental Properties Are Covered by Unincorporated Los Angeles County Rent Control?

One of the most common sources of confusion for landlords is determining whether their property is actually subject to the County’s rent stabilization ordinance.

Not every rental property located in Los Angeles County falls under the RSTPO.

The distinction is important because Los Angeles County contains numerous incorporated cities, many with their own rental housing regulations.

What Does Unincorporated Los Angeles County Mean?

Unincorporated areas are communities that fall under the direct jurisdiction of the Los Angeles County government rather than an incorporated city government.

Examples include Altadena, East Los Angeles, Florence-Firestone, and parts of South Whittier.

A rental property in one of these communities may be subject to the County’s RSTPO if it meets the applicable coverage requirements.

By contrast, a property within the City of Los Angeles is generally governed by the City’s rental housing regulations, not the County’s RSTPO.

A Los Angeles mailing address does not necessarily mean a property is located within the City of Los Angeles. ZIP codes and mailing addresses can cross jurisdictional boundaries.

Landlords should verify their property’s actual jurisdiction rather than relying on the city name appearing on a utility bill or property tax statement.

Which Properties Are Fully Covered by the RSTPO?

The County’s rent stabilization provisions generally apply to rental properties in unincorporated areas that have two or more rental units and a certificate of occupancy or equivalent permit issued on or before February 1, 1995.

The County also identifies certain accessory dwelling units and owner-rented mobilehomes as fully covered under its specific rules.

An important detail is that the County’s coverage description addresses rental units regardless of legal permit status. Landlords should not assume an unpermitted unit is automatically excluded from rent stabilization.

For example, consider a duplex constructed in 1985 in an unincorporated area of Los Angeles County. If the property does not qualify for an applicable exemption, its rental units would generally fall within the fully covered category.

The landlord would therefore need to follow the applicable RSTPO annual rent increase limitations.

Fully Covered vs. Partially Covered Rental Units

Los Angeles County distinguishes between fully covered and partially covered rental units.

Fully covered units are subject to the County’s rent stabilization limits and applicable tenant protections.

Partially covered units may be protected by the County’s just-cause eviction requirements without being subject to its local annual rent increase cap.

This distinction matters because a rental property that is not subject to the 1.919% County limit may still be covered by California’s statewide rent control law, AB 1482.

Property classification	County rent increase cap	County just-cause protections
Fully covered	Generally applies	Generally applies
Partially covered	Generally does not apply	May apply
Exempt	Does not apply	Depends on exemption

For landlords, the safest starting point is to establish the property’s coverage classification before calculating any proposed increase.

How Can Landlords Verify Their Property’s Coverage?

The Los Angeles County Department of Consumer and Business Affairs provides resources for identifying covered properties and managing registration obligations.

Landlords can begin with the official LA County Rent Stabilization Program and the County Rent Registry.

Review the property’s location, number of rental units, construction and occupancy records, and any potentially applicable exemptions.

If the property’s status is uncertain, particularly where an accessory dwelling unit, converted garage, or unusual ownership structure is involved, obtaining a property-specific determination before issuing a rent increase notice can help avoid costly mistakes.

Can Small Property Landlords Increase Rent by 2.919%?

Yes. Under the RSTPO, qualifying small property landlords may apply an additional one percentage point above the general annual allowance.

For the July 2026 through June 2027 period, this results in a maximum annual increase of 2.919% for eligible fully covered rental units.

However, not every landlord who considers themselves a small property owner automatically qualifies.

The County has established specific ownership and property requirements, along with an annual self-certification process.

Who Qualifies as a Small Property Landlord?

Under the County’s published criteria, a landlord may qualify through one of several pathways.

These include owners who qualify for and receive a homeowners’ property tax exemption for the property containing the rental unit.

Another pathway applies to an owner with an ownership or beneficial interest in, or control of, only one rental property containing no more than 10 rental units.

A third pathway covers certain owners with interests in or control of no more than three rental properties containing a combined total of no more than 10 rental units. Properties outside Los Angeles County must also be considered when determining eligibility.

The County’s complete definition and applicable ownership restrictions should be reviewed before claiming the additional allowance.

For example, an individual who owns a qualifying four-unit rental building in unincorporated Los Angeles County may meet the small property landlord requirements.

However, an owner with additional rental properties elsewhere in California cannot ignore those holdings when determining eligibility.

Annual Small Property Landlord Self-Certification Requirements

One particularly important requirement is the small property landlord self-certification LA County requires annually.

Qualifying owners must submit a Small Property Landlord Self-Certification form to the Department of Consumer and Business Affairs.

The certification is completed under penalty of perjury and confirms that the landlord meets the applicable requirements.

This is not simply a one-time declaration made when purchasing a property. The County requires annual certification.

Landlords should retain copies of their completed certifications and supporting ownership records.

The official form is available through the County’s Rent Stabilization Forms page.

Required Disclosure in the Rent Increase Notice

Small property landlords claiming the additional 1% must also include a disclosure in the written rent increase notice stating that they meet the County’s small property landlord requirements.

This is separate from submitting the annual certification to DCBA.

A landlord who qualifies based on property ownership should not assume that eligibility alone satisfies the procedural requirements.

Both the certification and the required notice disclosure deserve attention before an increase is implemented.

How Much Additional Rental Income Could a Small Landlord Receive?

Consider a qualifying landlord who currently charges $2,500 per month.

At the standard 1.919% rate, the new monthly rent would be approximately $2,547.98.

At the qualifying small property landlord rate of 2.919%, the new monthly rent would be approximately $2,572.98.

That represents an additional $25 per month, or $300 over 12 months, assuming the increased rent remains in effect throughout that period.

For a qualifying four-unit property with the same rent on each unit, the difference could total $1,200 annually.

These examples illustrate why understanding eligibility and completing the required certification can be financially meaningful for smaller property owners.

Which LA County Luxury Rental Units Qualify for a 3.919% Increase?

Certain luxury rental units in unincorporated Los Angeles County qualify for a higher annual rent increase.

For July 2026 through June 2027, the allowable increase for qualifying luxury units is 3.919%.

However, the County’s definition of a luxury unit is much more specific than simply charging a high monthly rent.

What Qualifies as a Luxury Unit Under the RSTPO?

According to the County’s published requirements, a qualifying luxury rental unit must satisfy all three of the following conditions:

1. The unit contains no more than two bedrooms.
2. The unit is located in a single structure containing at least 25 rental units.
3. The landlord received at least $4,000 per month in rent for the unit as of September 11, 2018.

All three requirements are important.

A newly renovated apartment renting for $5,000 today does not automatically qualify if it did not meet the historical rent requirement.

Similarly, a large luxury home or a three-bedroom apartment may not qualify even if its monthly rent is substantially higher than $4,000.

Why Historical Rent Documentation Matters

The September 11, 2018, requirement makes recordkeeping especially important.

Landlords seeking to establish luxury-unit eligibility should review historical lease agreements, rent ledgers, payment records, and building documentation.

These records can help establish whether the unit met the required rent threshold and whether the property satisfies the other conditions.

The County also requires a disclosure in the rent increase notice stating that the unit meets the luxury-unit requirements.

Landlords should verify qualification before applying the higher percentage rather than relying on the property’s current market value or rental rate.

LA County RSTPO vs. City of Los Angeles RSO: Which Rent Cap Applies?

The difference between Los Angeles County rent control and the City of Los Angeles Rent Stabilization Ordinance is one of the most important distinctions landlords need to understand.

Although both jurisdictions regulate certain residential rent increases, they operate under separate ordinances, with different coverage requirements, administrative agencies, and allowable percentages.

For July 2026 through June 2027, the standard annual rent increase under the City of Los Angeles RSO is 3%.

That is different from the 1.919% general allowance under the County’s RSTPO.

LA County vs. LA City Rent Cap Comparison

Requirement	Unincorporated LA County	City of Los Angeles
Governing ordinance	RSTPO	RSO
Standard 2026–2027 increase	1.919%	3%
General coverage age threshold	February 1, 1995	October 1, 1978
Primary agency	County DCBA	Los Angeles Housing Department
Annual rent registration	Required for covered units	Required for covered units
Rent increase frequency	Generally once every 12 months	Generally once every 12 months
Special increase provisions	Small landlords and luxury units	Separate City provisions and procedures

These construction and occupancy dates summarize the general rules. Exceptions and special property classifications may affect individual properties.

The City also amended its RSO annual rent increase formula effective February 2, 2026, and eliminated the former additional percentage increases for landlord-provided utilities.

How to Check Whether Your Property Is in LA City or Unincorporated LA County

For City of Los Angeles properties, landlords can use the official ZIMAS property information system.

Enter the property address and review the Housing section to determine whether the property is identified as subject to the City’s RSO.

For properties believed to be in unincorporated Los Angeles County, consult the County’s official jurisdiction and rent stabilization resources.

What About Other Cities in Los Angeles County?

The City of Los Angeles is not the only incorporated city with its own rental housing regulations.

Pasadena, Santa Monica, West Hollywood, and several other municipalities have local rent control or tenant protection requirements.

Consequently, a landlord who owns properties in multiple parts of Los Angeles County may need to follow different rules for each property.

For example, a rental unit in unincorporated East Los Angeles may be governed by the County’s RSTPO, while a qualifying rental unit within the City of Los Angeles would fall under the City’s RSO.

The property’s jurisdiction, rather than its general geographic proximity to Los Angeles, determines which local ordinance applies.

How Does California AB 1482 Affect LA County Landlords?

California’s Tenant Protection Act of 2019, commonly known as AB 1482, establishes statewide rent increase limitations and just-cause eviction protections for many residential rental properties.

Under AB 1482, covered rental units are generally subject to an annual rent increase limit of 5% plus the applicable change in the cost of living, with a maximum of 10%.

However, that does not mean landlords with fully covered RSTPO properties can choose the higher statewide allowance.

When Does the County’s Lower Rent Cap Apply?

For fully covered units subject to the County’s RSTPO, the local rent stabilization restrictions generally control the ordinary annual increase.

For example, a landlord with a fully covered duplex in unincorporated Los Angeles County cannot simply use the statewide AB 1482 percentage instead of the County’s published 1.919% general allowance.

Local rent stabilization ordinances may impose stricter limits than statewide law.

Landlords should therefore determine local coverage before consulting statewide limits.

What About Properties Not Fully Covered by the RSTPO?

Some rental properties are not subject to the County’s annual rent increase cap but may still fall under AB 1482.

This can include certain newer buildings, single-family residences, condominiums, and other property types, depending on their characteristics and applicable exemptions.

AB 1482 generally includes a rolling 15-year building-age exemption, along with specific exemptions for certain separately alienable residential properties and qualifying ownership arrangements.

Some exemptions also require particular disclosures to tenants.

For landlords, the key point is that an exemption from the County’s local rent cap does not automatically establish an exemption from California’s statewide rent control requirements.

A useful companion resource is a broader guide to California rent control laws, including how AB 1482 interacts with local ordinances.

LA County Rent Increase Notice Requirements for Landlords

Even when a landlord calculates the correct allowable percentage, an increase can create problems if the required procedures are not followed.

Under the RSTPO, landlords need to consider the timing of the increase, the written notice requirements, special disclosures, and property registration status.

The 12-Month Rule

For ordinary annual increases under the RSTPO, landlords generally must wait at least 12 consecutive months between increases.

For example, suppose a landlord’s previous rent increase became effective on December 1, 2025.

The landlord generally could not implement another ordinary annual increase before December 1, 2026.

The landlord would also need to provide the required advance written notice.

Landlords should review the effective date of the last increase rather than assuming that a new calendar year automatically creates another opportunity to raise rent.

Limited adjustments under separate ordinance procedures may have different requirements.

How Much Written Notice Is Required?

California Civil Code Section 827 generally requires at least 30 days’ advance written notice for residential rent increases of 10% or less, subject to applicable service rules.

Because the ordinary RSTPO annual percentages for 2026–2027 are below 10%, the general 30-day notice framework is relevant.

However, the method of serving the notice can affect the amount of time required.

Landlords should allow sufficient time for legally compliant delivery and retain documentation showing when and how the notice was served.

A rent increase should not be treated as effective simply because a notice was prepared or mailed.

Required Disclosures for Special Rent Increase Categories

Landlords claiming the additional small property landlord allowance must include a statement that they satisfy the applicable small property landlord requirements.

Similarly, landlords claiming the luxury-unit allowance must disclose that the rental unit meets the County’s luxury-unit criteria.

These disclosures are particularly important because they explain why the landlord is applying a percentage higher than the general allowance.

The County also maintains a Notice of Tenant Rights and related forms that landlords should review for applicable delivery and posting requirements.

Current documents are available on the DCBA Rent Stabilization Forms page.

Common Rent Increase Notice Mistakes

One frequent mistake is using the wrong annual percentage. A landlord who relies on the previous year’s RSTPO rate may calculate an increase that exceeds the current limit.

Another is confusing City and County regulations. The City of Los Angeles RSO and the County RSTPO have different rules, even though both apply within the broader Los Angeles region.

Landlords may also overlook the 12-month spacing requirement, omit a required small-landlord or luxury-unit disclosure, or fail to verify registration compliance.

Maintaining an organized record of previous increases, rent ledgers, notices, certifications, and service documentation can make future rent adjustments easier to manage.

LA County Rent Registry and Annual Registration Requirements

The Los Angeles County Rent Registry is an important part of RSTPO compliance.

Landlords with covered rental properties are required to provide applicable property and tenancy information through the County’s registration system and pay required annual fees.

Registration is more than an administrative formality. Failure to comply can affect a landlord’s ability to implement otherwise permissible rent increases.

Why Registration Matters Before Raising Rent

The County requires applicable registration and fee compliance for rent-stabilized properties.

A landlord may correctly calculate the 1.919% allowance but still encounter compliance problems if the property has unresolved registration or fee deficiencies.

Before issuing a rent increase notice, owners should confirm that their rental property information is accurate and their registration obligations have been satisfied.

This is especially important after changes in ownership, property management, tenancy, or the number of rental units.

How to Register a Rental Property

Landlords can access the County’s Rent Registry information and resources.

The registration process generally involves identifying the property, reviewing the applicable rental units, providing required information, and paying the corresponding fees.

Property owners should keep copies of registration confirmations and payment records.

Annual Registration Deadlines

The County generally uses September 30 as its annual registration deadline.

Landlords should review current DCBA instructions for the applicable registration year, including any announced extensions, administrative accommodations, or late-fee policies.

Because annual registration requirements can change, relying on an old deadline notice is not advisable.

For landlords managing several properties, maintaining a compliance calendar can help prevent missed registrations and unexpected delays when preparing future rent increases.

LA County Rent Increase Calculator: Examples for 2026–2027

Calculating an allowable rent increase is relatively straightforward once the correct percentage has been established.

The basic formula is:

New monthly rent = Current monthly rent × (1 + allowable increase percentage)

For example, if the current rent is $2,000 and the applicable percentage is 1.919%, multiply $2,000 by 1.01919.

The result is $2,038.38.

The following table shows how the three published RSTPO percentages affect common rental amounts.

Current monthly rent	General 1.919%	Small landlord 2.919%	Luxury 3.919%
$1,500	$1,528.79	$1,543.79	$1,558.79
$2,000	$2,038.38	$2,058.38	$2,078.38
$2,500	$2,547.98	$2,572.98	$2,597.98
$3,000	$3,057.57	$3,087.57	$3,117.57
$4,000	$4,076.76	$4,116.76	$4,156.76

These examples are mathematical illustrations only. The higher percentages require the appropriate qualifications, and a luxury unit must meet the County’s specific historical criteria.

Why the Maximum Allowable Percentage May Not Always Be Available

Even if a rental unit qualifies for a particular category, the landlord must still satisfy applicable procedural requirements.

For example, a qualifying small property landlord may be eligible for the 2.919% allowance but must also complete the annual self-certification and required notice disclosure.

Similarly, a landlord whose property has not satisfied applicable registration requirements should resolve those issues before proceeding.

The published percentage is an important starting point, but it is not the only consideration.

Landlord Checklist Before Raising Rent in LA County

Before issuing a rent increase notice, review the following items.

Pre-Increase Compliance Review

• Confirm whether the property is in unincorporated LA County or an incorporated city.
• Verify whether the rental unit is fully covered by the RSTPO.
• Identify the correct annual rent increase percentage.
• Check small property landlord or luxury-unit eligibility, if applicable.
• Complete annual small property landlord self-certification, if required.
• Confirm registration and fee compliance.
• Verify the date of the previous rent increase and applicable 12-month spacing.
• Calculate the proposed increase accurately.
• Prepare the required written notice and category disclosures.
• Confirm tenant-rights notice and posting obligations.
• Retain records of the calculation, notice, service, and supporting documents.

A consistent review process can help landlords avoid overlooked requirements, particularly when managing properties across several Southern California jurisdictions.

Frequently Asked Questions About LA County Rent Increases

How much can a landlord raise rent in LA County in 2026?

For fully covered rental units in unincorporated Los Angeles County, the standard allowable annual increase is 1.919% from July 1, 2026, through June 30, 2027. Qualifying small property landlords may apply 2.919%, while qualifying luxury units may use 3.919%.

Is the LA County rent increase limit 3% in 2026?

Not for general fully covered RSTPO units during the July 2026 through June 2027 period. Although the County’s formula includes a 3% general ceiling, the published allowable increase is 1.919%. The City of Los Angeles RSO has a separate 3% standard allowance for the same period.

Can a small landlord increase rent by 2.919% without self-certifying?

Qualifying small property landlords must submit an annual self-certification to DCBA and include the required disclosure in the rent increase notice. Ownership eligibility alone does not eliminate these requirements.

Does LA County rent control apply to single-family homes?

Single-family homes are generally not fully covered by the County’s RSTPO rent stabilization provisions, but they may be subject to other tenant protections or California AB 1482. The property’s ownership, configuration, and applicable exemptions should be reviewed.

Can landlords raise rent twice in one year?

Ordinary annual RSTPO rent increases generally must be spaced at least 12 consecutive months apart. Certain separately authorized adjustments may be governed by different procedures, so landlords should distinguish those from routine annual increases.

Does the RSTPO apply to Pasadena or Santa Monica?

No. The County’s RSTPO governs applicable properties in unincorporated Los Angeles County. Incorporated cities such as Pasadena and Santa Monica have their own applicable local rental housing laws.

What happens if a landlord misses the rent registration deadline?

Missing an applicable registration deadline can result in late fees or other compliance consequences. Registration deficiencies may also affect a landlord’s ability to implement rent increases. Owners should review current County requirements and resolve outstanding obligations.

Can landlords increase security deposits when raising rent?

For fully covered units under the County’s RSTPO, security deposit increases during an existing tenancy are restricted. Landlords should distinguish these rules from California’s statewide security deposit limits and the rules governing other jurisdictions.

What is the LA County rent increase limit for 2027?

The currently published RSTPO percentages of 1.919%, 2.919%, and 3.919% remain effective through June 30, 2027. Landlords planning increases effective July 1, 2027, or later should consult the County’s next annual bulletin.

Final Thoughts: Verify Your LA County Rent Increase Before Sending Notice

For landlords in unincorporated Los Angeles County, the 2026–2027 rent increase rules provide a clear set of percentages, but determining which one applies requires careful attention to the property’s characteristics and the owner’s qualifications.

The standard 1.919% allowance applies to general fully covered rental units, while qualifying small property landlords and luxury units may use higher percentages when the necessary conditions are satisfied.

Just as important, landlords must distinguish County regulations from the City of Los Angeles RSO and California’s statewide AB 1482 requirements.

Before implementing an increase, confirm the property’s jurisdiction and coverage, verify registration and fee compliance, review the previous increase date, and prepare the appropriate written notice.

Taking the time to review these requirements can help property owners manage rental income while reducing the risk of avoidable compliance problems.

For current information, consult the Los Angeles County Department of Consumer and Business Affairs and its published rent increase bulletins.
