ALLOWABLE ANNUAL RENT INCREASES
A landlord may increase the tenant’s base rent once every 12 months by the amount of the allowable annual rent increase without filing a petition at the Rent Board. Effective March 1, 2015 through February 29, 2016, the allowable annual increase amount is 1.9%. This amount is based on 60% of the increase in the Consumer Price Index for All Urban Consumers in the Bay Area, which was 3.2% as posted in November 2014 by the Bureau of Labor Statistics. To calculate the dollar amount of the 1.9% annual rent increase, multiply the tenant's base rent by .019. For example, if the tenant's base rent is $1,500.00, the annual increase would be calculated as follows: $1,500.00 x .019 = $28.50. The tenant's new base rent would be $1,528.50 ($1,500.00 + $28.50).
