1. Overview of Rent Control in Los Angeles County Unincorporated
The unincorporated areas of Los Angeles County — communities that fall outside the boundaries of any incorporated city — are home to hundreds of thousands of renters spread across the sprawling Los Angeles Metro region. These areas include neighborhoods such as East Los Angeles, Ladera Heights, West Athens, Altadena, and many others governed directly by the County rather than a city. Facing a severe affordability crisis and rising tenant displacement, the Los Angeles County Board of Supervisors enacted the Los Angeles County Rent Stabilization Ordinance (RSO), which took effect on April 1, 2020, making it one of the more recently enacted local rent control laws in California.
The County RSO applies exclusively to rental units in unincorporated areas of LA County built before February 1, 1995, as well as all mobile homes regardless of age. The ordinance caps annual rent increases, establishes just-cause eviction protections, and requires relocation assistance for certain no-fault evictions. It is administered by the LA County Department of Consumer and Business Affairs (DCBA). Importantly, incorporated cities within LA County — such as Los Angeles, Beverly Hills, Culver City, Inglewood, and others — operate under their own separate rent control ordinances, and the County RSO does not apply in those jurisdictions.
Renters whose units are not covered by the County RSO — for example, those in newer buildings or in single-family homes — may still benefit from California's statewide AB 1482 (Tenant Protection Act of 2019), which limits annual rent increases to 5% plus local CPI (up to 10% total) and provides just-cause eviction protections for qualifying tenants statewide. Understanding which law applies to your specific unit is the essential first step for any unincorporated LA County renter.
2. Who Is Covered by Rent Control in Los Angeles County Unincorporated?
The Los Angeles County RSO covers rental units that meet all of the following criteria within unincorporated areas of LA County:
The unit was built (certificate of occupancy issued) before February 1, 1995 — units built in 1994 or earlier are covered; units built in 1995 require month-level data to confirm coverage
The property is located in an unincorporated area of Los Angeles County (not within any incorporated city)
All mobile homes and mobile home spaces within unincorporated LA County, regardless of when they were built
The following unit types are exempt from the County RSO:
Single-family homes (under Costa-Hawkins and the County ordinance)
Condominiums and condos
Units built on or after February 1, 1995
Units in incorporated cities — these are governed by each city's own ordinance or AB 1482
Subsidized affordable housing units with rent restrictions set by regulatory agreement
Units where the landlord and tenant share a kitchen or bathroom (owner-occupied, renter-adjacent situations)
If your unit is not covered by the County RSO, California's AB 1482 may still apply if your unit was built more than 15 years ago and is not a single-family home or condo sold to a new owner after January 1, 2020. AB 1482 caps annual increases at 5% plus local CPI (maximum 10%) and requires just cause for eviction after 12 months of tenancy.
3. Maximum Allowable Rent Increases
Under the Los Angeles County RSO, annual rent increases for covered units are capped at a flat percentage set periodically by the Board of Supervisors. As of November 2023, the cap was set at 4% per year, extended through June 2024. Landlords should check with the LA County DCBA for the current applicable rate, as the Board of Supervisors reviews and may update the cap on an ongoing basis.
Key rules governing rent increases under the RSO include:
Landlords must provide proper written notice — at least 30 days for increases under 10%, or 90 days for increases of 10% or more
Only one rent increase per 12-month period is permitted per unit
Landlords may apply to the DCBA for a capital improvement pass-through if they have made substantial improvements to the property; approved costs may be passed through to tenants as a temporary surcharge
Landlords may also petition for a rent increase above the cap based on a just and reasonable return, subject to DCBA review
Banked increases (accumulating unused increases from prior years) are generally not permitted under the County RSO
For units not covered by the RSO, AB 1482's cap of 5% + local CPI (not to exceed 10% total) applies as a statewide backstop. Always verify the current allowable increase with the DCBA before accepting or disputing a notice of rent increase.
4. Just Cause Eviction Protections
The LA County RSO requires landlords to have a legally recognized just cause reason before evicting any tenant in a covered unit. Just-cause reasons fall into two categories:
At-Fault Just Cause (tenant is responsible):
Nonpayment of rent
Violation of a material lease term after written notice to cure
Causing or permitting a nuisance on the property
Using the unit for an illegal purpose
Refusal to renew a lease on similar terms
Refusal to allow lawful entry by the landlord after proper notice
No-Fault Just Cause (tenant is not at fault):
Owner move-in (landlord, spouse, domestic partner, child, or parent intends to occupy the unit as a primary residence)
Withdrawal of the unit from the rental market (Ellis Act)
Demolition or substantial rehabilitation requiring the unit to be vacant
Government order requiring vacancy
For all no-fault evictions, the landlord is required to pay relocation assistance to the displaced tenant. The amount varies based on tenure and unit size — tenants who have lived in their unit for three or more years or who are low-income, elderly, or disabled are entitled to higher relocation payments. Tenants should contact the DCBA to confirm the current relocation assistance schedule.
AB 1482 provides overlapping just-cause eviction protections for qualifying tenants in units not covered by the County RSO, including a relocation assistance requirement of one month's rent for no-fault terminations. The County RSO's protections are generally broader and more tenant-protective than AB 1482 for covered units.
5. Local Rules and Special Protections
The Los Angeles County Department of Consumer and Business Affairs (DCBA) administers the County RSO and serves as the county's rent board equivalent. The DCBA maintains a registry of covered rental properties, processes petitions from both landlords and tenants, and enforces compliance with the ordinance.
Landlord Registration: Landlords with RSO-covered units are required to register their rental properties with the DCBA annually and pay a registration fee. Landlords who fail to register may be prohibited from implementing any rent increases until they come into compliance.
Tenant Petitions: Tenants who believe their landlord has violated the RSO — for example, by raising rent above the allowable cap, failing to maintain habitable conditions, or retaliating against a tenant for asserting their rights — may file a petition with the DCBA. Petitions can be submitted online, by mail, or in person at DCBA offices. The DCBA will investigate and may order the landlord to refund excess rent or take corrective action.
Landlord Petitions: Landlords may file a petition seeking approval for a rent increase above the standard cap based on increased operating costs or to achieve a fair rate of return. The DCBA reviews these applications and holds hearings if necessary.
Anti-Harassment Protections: The County RSO includes anti-harassment provisions prohibiting landlords from interfering with a tenant's right to peaceful enjoyment of their home, threatening or intimidating tenants, refusing to perform necessary repairs as leverage, or retaliating against tenants who report violations or organize with other tenants. Tenants experiencing harassment may file a complaint with the DCBA or pursue legal action.

Find out if your home is covered by rent control or tenant protections.
Does Los Angeles County Unincorporated have rent control?
Yes. The Los Angeles County Rent Stabilization Ordinance (RSO), effective April 1, 2020, provides rent stabilization and just-cause eviction protections for qualifying renters in unincorporated areas of LA County. The RSO applies to rental units built before February 1, 1995, and to all mobile homes in unincorporated areas. Renters in incorporated cities within LA County are governed by each city's own ordinance, not the County RSO.
What is the rent increase cap in Los Angeles County Unincorporated?
The LA County RSO capped annual rent increases at 4% as of November 2023, with that rate extended through June 2024. The Board of Supervisors reviews and sets the allowable increase periodically, so tenants should confirm the current cap with the DCBA at (800) 593-8222 or dcba.lacounty.gov/rentstabilization. Landlords are limited to one rent increase per 12-month period per covered unit.
Is my unit covered by Los Angeles County Unincorporated's rent control ordinance?
Your unit is covered by the County RSO if it is located in an unincorporated area of LA County, was built before February 1, 1995 (or is a mobile home of any age), and is not a single-family home or condominium. If your unit was built in 1995, month-level data is needed to confirm coverage. Use RentCheckMe's address checker or contact the DCBA to verify whether your specific address falls within an unincorporated area and meets the ordinance's criteria.
Can my landlord evict me without just cause in Los Angeles County Unincorporated?
No — if your unit is covered by the LA County RSO, your landlord must have a legally recognized just-cause reason to evict you, whether at-fault (such as nonpayment of rent or lease violation) or no-fault (such as owner move-in or Ellis Act withdrawal). No-fault evictions require the landlord to pay relocation assistance, with higher amounts for long-term tenants, seniors, disabled tenants, and low-income households. Tenants in units not covered by the RSO may still have just-cause protections under AB 1482 after 12 months of tenancy.
How do I contact the Los Angeles County Unincorporated Rent Board?
The LA County Department of Consumer and Business Affairs (DCBA) administers the RSO in lieu of a standalone rent board. You can reach the DCBA's Rent Stabilization Program by phone at (800) 593-8222 or online at dcba.lacounty.gov/rentstabilization. The DCBA accepts tenant petitions, handles landlord registration questions, and can confirm whether your address is in an unincorporated area covered by the ordinance.
