1. What is California AB 1482 Rent Control?

California's AB 1482 is a statewide rent control law that limits annual rent increases 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 in California that are more than 15 years old.

2. How Does the Rent Increase Calculator Work?

The calculator uses the AB 1482 formula:

\[ \text{New Rent} = \text{Current Rent} \times (1 + \min(\text{CPI} + 5\%, 10\%)) \]

Where:

Current Rent — The tenant's current monthly rent amount
CPI — Consumer Price Index percentage for the region
5% — The fixed percentage allowed under AB 1482
10% — The maximum allowed annual increase under AB 1482

Explanation: The formula calculates the maximum allowable rent increase under California law, which is the lesser of 10% or (CPI + 5%).

3. Understanding the Rent Increase Formula

Details: The CPI used should be the percentage change from April of the prior year to April of the current year for the region where the property is located. The 5% base increase plus CPI cannot exceed 10% in any 12-month period.

4. Using the Calculator

Tips: Enter the current rent amount in USD and the applicable CPI percentage. The calculator will show the maximum allowed new rent, the percentage increase, and the dollar amount of the increase.
