CPI (AB1482) Rent Increase Calculator 2023
Please Read This Before Using: This calculator should be used to calculate allowable rent increases (under AB 1482) effective as of August 1st, 2023 and should not be used to determine any increase amount retroactively.
Besides San Bernardino and Riverside County, where the consistent amount is 9.6%, all other areas have varying percentages. Therefore, it’s essential to verify the specific amount applicable before considering raising your rent. Until 31st July 2023, if the 30-day notice was served before 1st August 2023 and the increase does not take effect after that date (meaning the last day to serve a 10% increase notice would be 30th June 2023, to be on the safe side), the maximum allowed annual increase is 10%.
As of now, if you haven’t served an increase notice to be effective before 1st August 2023 will need to re-serve it based on the corresponding amounts unless they are exempt from AB 1482.

As we all know, AB 1482 (Assembly Bill 1482) took effect on January 1st, 2020 and introduced restrictions to evictions and statewide rent increases on most residential rental properties in California. Rental properties subject to the rent increase cap are allowed annual rent increases of 5% plus local CPI but no more than 10%, whichever is lower.
