1. What is AB 1482 Rent Cap?

The California Tenant Protection Act (AB 1482) limits annual rent increases to 5% plus the percentage change in the cost of living (CPI), with a maximum cap of 10%. This calculator helps determine the maximum allowable rent increase under this law.

The calculator uses the AB 1482 formula:

\[ \text{New Rent} = \text{Old Rent} \times \left(1 + \frac{\min(5 + \text{CPI}, 10)}{100}\right) \]

Where:

Explanation: The law allows landlords to increase rent by either 5% plus CPI or 10%, whichever is lower.
