San Francisco Rent Control Rules
San Francisco’s rent control ordinance is administered by the SF Rent Board and applies to most residential units in buildings with two or more units built before June 13, 1979. The annual allowable increase for 2026 is 1.7% — one of the lowest in the state.
Unlike AB 1482, the SF Rent Board does not allow vacancy decontrol. Landlords must also comply with the SF Rent Board’s just cause eviction protections, which are stricter than AB 1482’s provisions. Capital improvement passthroughs and operating expense increases require a petition to the Rent Board.
SF landlords must file annual rent increase notices with the Rent Board and are required to provide tenants with a copy of the Rent Board’s informational materials at the start of each tenancy.

AB 1482 applies to San Francisco properties not covered by the Rent Board, including:
- Buildings built between June 1979 and 2011 — covered by AB 1482 at 6.3%
- Single-family homes and condos — if the owner is not a corporate entity and provides written exemption notice
- Buildings less than 15 years old (post-2011) — exempt from both the Rent Board and AB 1482
Frequently Asked Questions
What is the maximum rent increase in San Francisco in 2026?
For units covered by the SF Rent Board (2+ units built before June 1979), the maximum increase is 1.7% for 2026. For units covered only by AB 1482, the cap is 6.3% (5% + 1.3% CPI). Units built after 2011 are exempt from both.
Is my San Francisco rental covered by the Rent Board or AB 1482?
If your building has 2 or more units and was built before June 13, 1979, it is likely covered by the SF Rent Board (1.7% cap). If it was built between 1979 and 2011, AB 1482 applies (6.3% cap). Buildings built after 2011 are exempt from both. You can verify your property’s status through the SF Rent Board’s online lookup tool.
Can I bank unused rent increases in San Francisco?
Yes, under the SF Rent Ordinance, landlords can bank unused annual allowable increases. If you did not raise rent in a prior year, you may carry that increase forward and apply it in a future year, subject to Rent Board rules. This is more restrictive than AB 1482, which does not have a formal banking mechanism.
