The City of Los Angeles Rent Stabilization Ordinance (RSO) was enacted in 1978 to regulate rent increases and provide tenant protections. The ordinance, which is overseen by the Los Angeles City Council, applies to most multi-family rental units built and occupied before October 1, 1978, and includes provisions such as caps on rent hikes, just-cause eviction requirements, and relocation assistance. The RSO aims to stabilize the rental market and protect tenants from excessive rent increases, with the allowable rent increase percentage changing annually. In addition to the RSO, Los Angeles County has implemented the Mobilehome Rent Stabilization and Mobilehome Owner Protections Ordinance (MRSMOPO) and the Rent Stabilization and Tenant Protections Ordinance (RSTPO), which provide similar protections for mobile home spaces and residential units in unincorporated areas of the county.

The Rent Stabilization Ordinance (RSO) was enacted in 1978
The Rent Stabilization Ordinance (RSO) was enacted in Los Angeles in 1978 to address the city's housing affordability challenges. The RSO is a set of regulations that aim to stabilize rent increases, protect tenants, and ensure affordable housing for Los Angeles residents. It applies to most multi-family rental units built and occupied before October 1, 1978, excluding single-family homes and condominiums.
The RSO governs rent control by limiting how much a landlord can increase a tenant's rent. It also prohibits the eviction of tenants without a valid reason, also known as "just cause." The ordinance covers the types of evictions that require relocation payments to tenants and regulates buyout agreements. Additionally, it provides a process for property owners to seek relief if they believe they are not receiving a fair return on their rental units under the permitted maximum annual rent increase.
The Los Angeles Housing Department (LAHD) oversees the RSO and investigates any potential violations. Tenants who believe their landlord has violated the ordinance or is living under unsafe or unhealthy conditions can file a complaint with the LAHD. The LAHD also provides informational workshops and resources for landlords and tenants to understand their rights and responsibilities under the RSO.
The RSO has undergone updates and amendments over the years to adapt to changing circumstances and address any gaps in tenant protections. For example, effective March 30, 2020, through January 31, 2024, rent increases were prohibited for rental units subject to the RSO. Additionally, the City of Los Angeles implemented a separate Just Cause Ordinance (JCO) in January 2023, providing just-cause eviction protection for properties not covered by the RSO.
The RSO is just one aspect of Los Angeles's broader approach to rent control and tenant protections. The Los Angeles County Rent Stabilization and Tenant Protections Ordinance (RSTPO) and the Los Angeles County Mobile Home Rent Stabilization and Mobile Home Owner Protections Ordinance (MRSMOPO) are also in place to regulate rent increases and protect tenants in unincorporated areas of Los Angeles County. These ordinances work in tandem with state-level legislation, such as the California Tenant Protection Act of 2019 (California Rent Control), to ensure comprehensive rent control and tenant protection measures are in place.

It applies to multi-family rental units built before October 1, 1978
The Los Angeles Rent Stabilization Ordinance (RSO) was enacted in 1978. It applies to multi-family rental units built before October 1, 1978, excluding single-family homes and condominiums. The RSO is a set of regulations that aim to stabilize rent increases, provide tenant protections, and ensure affordable housing for Los Angeles residents.
The ordinance includes several provisions that protect tenants and regulate the rental market. For example, rent may only be increased once every twelve months and cannot exceed the annual rent increase percentage determined by the Rent Adjustment Commission (RAC). The allowable rent increase percentage changes annually and tenants can contact the Los Angeles Housing Department (LAHD) to determine the exact percentage or use the LAHD's rent increase calculator.
The RSO also prohibits landlords from raising rents by more than 10% for units covered by rent control in a single year. In 2024, the allowable rent increase was capped at 4% for units where the landlord pays utilities and 6% for units where tenants pay utilities. These caps are set by the Los Angeles County Board of Supervisors and are subject to change.
Additionally, the RSO covers what types of evictions require relocation payments to tenants and regulates buyout agreements. It also prohibits no-fault evictions and requires landlords to provide a valid reason for terminating a tenancy. Tenants who believe their landlord has violated the ordinance or is providing unsafe or unhealthy living conditions can file a complaint with the LAHD.
The RSO is just one of the many rent control ordinances in Los Angeles that aim to stabilize the rental market and protect tenants from excessive rent hikes. The Los Angeles County Rent Stabilization and Tenant Protections Ordinance (RSTPO) is another example, limiting annual rent increases for rent-stabilized units based on changes in the Consumer Price Index (CPI). The RSTPO also provides a process for property owners to seek relief if they believe they are not receiving a fair return on their rental units.

The RSTPO limits annual rent increases based on the Consumer Price Index (CPI)
The Los Angeles County Rent Stabilization and Tenant Protections Ordinance (RSTPO) is a local law that limits annual rent increases for rent-stabilized units based on changes in the Consumer Price Index (CPI). The RSTPO also covers mobile home spaces in unincorporated areas of Los Angeles County, known as the Los Angeles County Mobilehome Rent Stabilization and Mobilehome Owner Protections Ordinance (MRSMOPO).
The RSTPO/MRSMOPO limits annual rent increases to a percentage of the change in the average CPI over the previous 12 months. From January 1, 2024, through December 31, 2024, the maximum rent increase will be 4%. For fully covered rental units subject to LACC Section 8.52.050, the annual rent increase is limited to 60% of the change in the CPI over the previous 12 months, not exceeding a maximum rent increase of 3%.
The RSTPO/MRSMOPO also provides a process for property owners to seek relief if they believe they are not receiving a fair return on their rental units due to the permitted maximum annual rent increase. In certain situations, landlords may increase rent beyond the allowable limit if they can demonstrate that they are not receiving a fair return, such as passing on costs related to property improvements, renovations, and annual registration fees.
The City of Los Angeles also has its own Rent Stabilization Ordinance (RSO), which regulates rent increases and evictions for tenants in various neighborhoods and districts within the city. The RSO is overseen by the Los Angeles Housing Department (LAHD), which investigates violations and provides informational workshops for tenants and landlords. Tenants should note that the RSO only applies to rental properties built on or before October 1, 1978, and rent may only be increased once every 12 months by the allowable rent increase percentage.

Tenants are protected from eviction without a valid reason
The Los Angeles County Rent Stabilization and Tenant Protections Ordinance (RSTPO) is a local law that limits annual rent increases based on changes in the Consumer Price Index (CPI). It also protects tenants in residential units from being evicted without a valid reason, also known as "just cause".
The RSTPO provides a process for property owners to seek relief if they believe they are not receiving a fair return on their rental units under the permitted maximum annual rent increase. Beginning on January 1, 2024, rental units subject to the RSTPO will be restricted to a maximum rent increase of 4% through December 31, 2024.
The City of Los Angeles Rent Stabilization Ordinance (RSO) regulates how much a landlord can increase a tenant's rent and prohibits the eviction of tenants unless the landlord has a just-cause reason under the law to do so. The RSO also covers what types of evictions require relocation payments to tenants and regulates buyout agreements.
The Los Angeles Housing Department (LAHD) oversees the RSO and investigates violations of the ordinance. If a tenant believes their landlord has violated the ordinance or if they are living under unsafe or unhealthy conditions, they may file a complaint with the LAHD. Tenants can also access the Los Angeles County Rent Registry system to verify coverage under the RSTPO and other ordinances.
Additionally, the City of Los Angeles implemented a separate Just Cause Ordinance (JCO) on January 27, 2023, which provides just-cause eviction protection for most properties that are not covered under the RSO. While the JCO does not regulate how much a tenant's rent can be increased, it does provide relocation benefits for tenants who move due to a large rent increase.
Under the Tenant Protection Act of 2019, landlords in California must have a valid reason to evict renters, as long as the renter has lived in the rental housing for at least 12 months. This is known as "just cause" protection for eviction. At-fault reasons for eviction include non-payment of rent, breaking a material rule in the lease or rental agreement, criminal activity, subletting if the lease does not allow it, and refusing to sign a new lease with similar terms. It is also illegal for a landlord to lock out tenants, remove doors or windows, change locks, cut off utility services, or use other forms of harassment to make tenants move out.

The RSO covers rental units in many LA neighbourhoods and districts
The Rent Stabilization Ordinance (RSO) in Los Angeles covers rental units in many neighbourhoods and districts. The RSO regulates how much a landlord can increase a tenant's rent, and it prohibits the eviction of tenants unless the landlord has a just-cause reason under the law. The ordinance also covers what types of evictions require relocation payments to tenants and regulates buyout agreements.
The RSO covers rental units in areas such as Echo Park, Encino, Highland Park, Hollywood, La Brea, Los Feliz, Northridge, San Pedro, Studio City, Van Nuys, and Venice. It is important to note that the RSO generally applies to rental properties that were first built on or before October 1, 1978, as well as replacement units under LAMC Section 151.28. This includes rooms in a hotel, motel, rooming house, or boarding house occupied by the same tenant for more than 30 consecutive days, as well as residential units attached to commercial buildings.
Mobile homes and recreational vehicles in mobile home parks are also covered under the RSO. However, there may be differences in the application of rent control to these types of units, so tenants in these situations should consult a tenant attorney to understand their protections under the ordinance.
The RSO also allows for rent increases in certain situations, such as when an additional tenant moves into a rental unit. Landlords can increase the rent within 60 days of learning about the additional tenant, but there is no increase for the first minor dependent child added to an existing rental unit. Additionally, landlords can recover costs for improvements to the rental unit or common areas that benefit the tenant and will last at least five years.
To determine if a rental unit is subject to the RSO, tenants can enter their address into the Los Angeles Housing Department's (LAHD) system, which will indicate the RSO status of the property. The LAHD is responsible for overseeing the ordinance and investigating any potential violations.
