Full Breakdown
Charter Section 1707 sets the Annual General Adjustment that Covered Rental Units may receive each year. By June 30th, the Rental Housing Committee must announce the adjustment, effective every September 1st, calculated as 100 percent of the CPI increase (All Urban Consumers, San Francisco-Oakland-San Jose region) for the twelve months ending in March, rounded to the nearest tenth of a percent, but never less than 2 percent nor more than 5 percent. Only one rent increase may be imposed on a tenant in any twelve-month period, and it becomes effective only after the landlord gives the tenant written notice with at least 30 days' advance notice.
A landlord who skips an Annual General Adjustment in a given year may bank it and impose the unimplemented amount later, though banked increases do not carry over to a successor landlord and the overall increase in any twelve-month period, banked or not, cannot exceed 10 percent of the rent then charged unless a Hearing Officer or the Committee approves a larger increase through a Landlord Petition for Upward Adjustment. 10, or failed to make repairs ordered by a Hearing Officer, the Committee, or the City.
Violations & Fines
An increase that skips the 30-day written notice, exceeds the annual cap without an approved Landlord Petition, or is imposed while the landlord is out of compliance with the Article, habitability code, or a repair order is simply not effective, meaning the tenant owes only the prior lawful rent. Tenants and the Committee can challenge noncompliant increases, and a landlord who has failed to file required notices or maintain the unit forfeits the right to collect the increase.
