California AB 1482 Rent Increase Formula:
| From: | To: |
The Tenant Protection Act of 2019 (AB 1482) limits annual rent increases in California to no more than 5% plus the percentage change in the cost of living (CPI), or 10% (whichever is lower). This applies to most rental properties more than 15 years old.
The calculator uses the AB 1482 formula:
Where:
Example: If CPI is 3% and current rent is $2000:
Allowed increase = Min(3% + 5%, 10%) = Min(8%, 10%) = 8%
Rent increase = 8% × $2000 = $160
New rent = $2000 + $160 = $2160
Details: These limits help protect tenants from excessive rent hikes while allowing landlords reasonable increases to cover rising costs. The law applies to most residential properties in California built more than 15 years ago.
Tips: Enter the current CPI percentage for your area (available from government sources) and your current monthly rent. The calculator will show the maximum allowed increase under AB 1482.
Q1: Does AB 1482 apply to all rental properties?

Q2: How often can rent be increased under AB 1482?
A: Landlords can only increase rent once every 12 months under these limits.
Q3: Where do I find the CPI for my area?

Q4: Can local rent control laws be stricter?
A: Yes, some cities have stricter rent control ordinances that override AB 1482. Always check local regulations.
Q5: What if my landlord tries to increase rent more than allowed?
A: You may have legal recourse. Contact a tenant rights organization or housing attorney for advice.
