Under the ordinance, the maximum annual rent increase is called the Annual General Adjustment (AGA). The AGA is set at 60% of the percentage increase to the April Consumer Price Index (CPI) for the San Francisco-Oakland-Hayward region for the time period of September 1, 2023 to and through August 31, 2024. The AGA can never go above 5% or below 0%.
In most cases, the AGA will be lower than 5%. This year, the regional CPI published in April, 2023 was 4.2%. 60% of 4.2% is 2.52%, therefore, for the time period of September 1, 2023 to and through August 31, 2024 the maximum annual rent increase is 2.52%.
By June 30 each year, the maximum allowable rent increase will be recalculated based on the change in April CPI over the last 12 months. Landlords are allowed to increase rents one time between September 1 of that year and August 31st of the following year. The maximum annual rent increase will be announced no later than June 30, 2024 next year, effective September 1, 2024. For the calculation effective September 1, 2024, the maximum rent increase will be 75% of the April, 2024 CPI.
