Introduction

Rent increases are a common part of owning and managing rental property, but in California, they must follow specific state laws. Understanding how rent increases work protects property owners from costly legal mistakes and ensures tenants receive fair and consistent treatment. With rising housing costs and changing statewide regulations, staying informed is essential for both landlords and tenants.

California’s Rent Cap Law

California’s statewide rent cap, known as AB 1482, limits how much rent can be increased each year for many residential properties. In most cases, the maximum allowable increase is five percent plus the local rate of inflation, measured by the Consumer Price Index, with a total cap of ten percent.

This means that even if inflation rises unusually high, the maximum rent increase cannot exceed ten percent in a single twelve month period.

Properties Covered and Properties Exempt

Not all properties fall under AB 1482. The law generally applies to:
• Most multi family properties more than fifteen years old
• Most rental homes owned by corporations or trusts

The law does not apply to:
• Single family homes and condos owned by individuals or family trusts, as long as a notice of exemption is included in the lease
• New buildings less than fifteen years old
• Owner occupied duplexes

Because exemptions can sometimes be misunderstood, it is important to verify your property’s status before issuing any notice of rent increase.

Notice Requirements for Rent Increases

California law also regulates how much advance notice a landlord must provide.
• If the total rent increase for the year is up to ten percent, the landlord must give at least thirty days written notice.
• If the increase would be above ten percent, a sixty day notice is required.

Even if your property is exempt from the statewide rent cap, you must still follow the notice requirements. Notices must be written clearly and delivered according to legal guidelines.

The Importance of Documentation

Clear documentation protects both the landlord and the tenant. This includes:
• A written notice of the increase
• The date the increase goes into effect
• The calculation or reason for the new rent amount
• A confirmation that the property is either covered by or exempt from AB 1482

Keeping complete records ensures transparency and prevents disputes.

Best Practices for Communicating Rent Increases

Communication is key. When tenants understand why a rent increase is happening, they are more likely to stay and continue a positive relationship. Providing reasonable explanations, offering advance reminders, and discussing maintenance improvements all help maintain trust.

Conclusion

Rent increases are a natural part of owning rental property, but they must be handled carefully to remain compliant with California law. Understanding AB 1482 and following proper notice procedures ensures fairness, consistency, and protection for both owners and tenants.
