Is there rent control for ADU units in California?
Navigating the complexities of rent control for Accessory Dwelling Units in California requires a nuanced understanding of state and local regulations. While California has made strides in promoting ADU development, the application of rent control remains a patchwork of varying city ordinances.

The Landscape of Rent Control in California
Local Jurisdiction Authority
California law grants cities and counties the authority to enact their own rent control ordinances. This results in a diverse landscape, with some cities having robust rent control measures while others have none.
Cities with Rent Control
Cities like Los Angeles and San Francisco have established rent control ordinances that may extend to ADUs. These ordinances typically include limitations on annual rent increases, eviction restrictions, and regulations on security deposits and other tenant fees.
Cities Without Rent Control
For example, San Diego and Sacramento generally do not have city-wide rent control ordinances. Landlords have greater flexibility in setting rental rates and terms in these areas.
Statewide Regulations
While local rent control varies, California has enacted some statewide tenant protections, such as the Tenant Protection Act of 2019 (AB 1482). AB 1482 limits annual rent increases for specific residential properties and requires "just cause" for evictions. However, there are exemptions to AB 1482, and ADUs can sometimes be exempt.

AB 1482 and ADUs
AB 1482 limits the amount of rent that can be increased in a 12-month period. There are exemptions to AB 1482, and often, those exemptions are for new construction. A legal professional should determine whether or not a newly created ADU is exempt from AB 1482.
Local Ordinance Interpretation
The interpretation of local rent control ordinances regarding ADUs can be complex. It is crucial to consult with local housing authorities or legal professionals to determine the specific regulations that apply to your ADU.
Exemptions
Some ADUs may be exempt from local rent control ordinances or statewide regulations. Exemptions often depend on factors such as the date of the ADU's construction, whether it is attached or detached, and whether it is owner-occupied.
Landlord Responsibilities and Tenant Rights
Fair Housing Laws
All landlords must comply with federal and state fair housing laws regardless of rent control regulations. These laws prohibit discrimination based on protected characteristics, ensuring equal housing opportunities.
Tenant Rights
Tenants in ADUs have the same rights as tenants in any other rental property, including the right to a safe and habitable living environment. Landlords must adhere to all applicable landlord-tenant laws, including those related to security deposits, eviction procedures, and maintenance responsibilities.
Rental Agreements
A well-drafted rental agreement must clearly define the tenancy terms, including rent payment, security deposits, and maintenance responsibilities.
