Understanding Rent Increases in California
If you’re a California tenant facing an unexpected rent increase, it’s important to understand what your landlord can—and cannot—legally do. Unfortunately, Tenant Law Group cannot assist all tenants who contact our firm with direct legal representation. However, we believe that all California renters deserve access to information. This page is a free resource to help tenants understand how rent increases work, when they’re legal, and what to do if your rent increase seems illegal.
Is My Rent Increase Legal?
In California, the rules for rent increases depend on the type of housing you live in, where it’s located, and how long you’ve lived there. For most residential tenants, rent increases are regulated by the Tenant Protection Act of 2019 (AB 1482), which is codified under California Civil Code § 1947.12. This law sets statewide limits on rent increases for certain types of rental housing and aims to protect tenants from excessive rent hikes. This law applies to:
Apartments and rental homes for which a certificate of occupancy was issued more than 15 years ago.
Units not already covered by local rent control.
Units in which a tenant has resided for more than 12 months.
Key Rent Increase Limits Under the Tenant Protection Act:
- ● The landlord may raise rent only once in any 12-month period.
- ● The increase must not exceed 5% of the current rent plus inflation, or 10% total, whichever is less.
- ● The rental increase must comply with California Civil Code Section 827 when it comes to length and form of notice.
Does My City Have Its Own Rent Control Laws?
Many cities in California have stronger rent control laws than the state’s default protections. Local ordinances often limit rent increases to a smaller percentage, apply to newer buildings, and require registration of rent hikes.
Visit our Rent Control Directory to learn more about protections available in your city.
You may be covered by local rent control if you live in cities such as:
- ● Los Angeles.
- ● San Francisco.
- ● Oakland.
- ● Berkeley.
- ● San Jose.
- ● Santa Monica, and others.
What Should I Do If My Rent Increase Seems Illegal?
You may be dealing with an illegal rent increase if:
- ● The increase exceeds state or local caps.
- ● Your landlord raises rent in retaliation for requesting repairs or reporting violations.
- ● You didn’t receive proper written notice.
If this happens:
- ● Request Written Clarification: Ask your landlord to confirm the new rent amount, effective date, and reason in writing. Keep a copy of their response.
- ● Gather Documentation: Save the rent increase notice, your lease, proof of past rent payments, and any emails or texts about repairs or complaints.
- ● Check Local Laws: If you’re in a rent-controlled city, your increase may be capped. Even if not, you may still be protected by AB 1482.
- ● Report to Local Agencies: If you believe the increase is illegal.
- Look Up Your Local Rent Board or Housing Department: For example “San Francisco Rent Board,” “Los Angeles Housing Department.”
- Submit a Complaint: Find the complaint form on your city’s official site, fill out the form, and submit it online, by mail, or in person (based on your city’s process).
- Follow Up: Save all emails, confirmations, and communications. Some boards may require a hearing or investigation.
Protecting Yourself From Unfair Rent Increases
A sudden rent increase can create financial strain and uncertainty—but you’re not powerless. California law and many local ordinances limit how often and how much your rent can be raised. By knowing your rights, keeping documentation, and acting quickly, you can challenge unfair increases.
