• Rent increases can only be given after 12 or more months have elapsed from the date of the rental agreement or the date of the last rent increase and must be accompanied by a 30-day increase notification.
• All or a portion of past annual allowable increases that have not been imposed can be accumulated or "banked" for imposition on or after a later anniversary date.
• When giving an annual increase, and it has been more than one year but less than two years since the last increase was given, the new increase is not considered a "banked" increase and an owner is only entitled to the annual increase amount in effect at the time the notice of rent increase takes effect. An increase is considered "banked" only if at least a full 24 months has elapsed since the last increase was given or the initial rent was set.

Because incorrect rent increases can result in very costly errors, it is important for owners to understand how to properly calculate rent increases. For help in figuring out rent increases, please contact Lingsch Realty or the San Francisco Rent Board.
