The maximum annual rent increase is called the Annual General Adjustment (AGA). Under the ordinance, the AGA is set at 60% of the annual percentage increase to the April, 2023 Consumer Price Index (CPI) for the San Francisco-Oakland-Hayward region for the period from September 1, 2023 to August 31, 2024. The AGA can never go above 5%.
In most cases, the AGA will be lower than 5%. The April, 2023 CPI increase was 4.2%. Sixty percent of 4.2% is 2.52%. Therefore the AGA for the time period from September 1, 2023 to and through August 31, 2024 is 2.52%.
By June 30th of each year, the maximum allowable rent increase will be recalculated based on the change in CPI over the last 12 months, calculated using April’s CPI figure. Landlords are allowed to increase rents one time between September of that year and September of the following year.
