How San Francisco Landlords Calculate Annual Rent Caps

Housing and Building Standards California 4 Minutes Read ยท published February 06, 2026 Flag of California

San Francisco, California landlords subject to local rent regulation must follow the Rent Board rules and published Annual General Adjustment when calculating allowable yearly rent increases. This guide explains the common legal steps landlords use to compute caps, when increases may be limited by ordinance, and where to file petitions or complaints under San Francisco law.

How annual caps are calculated

Most regulated rental units in San Francisco are governed by the San Francisco Rent Ordinance and the Rent Board's Annual General Adjustment (AGA). Landlords typically start with the previous permitted rent, apply the AGA percentage for the relevant year, and check for program-specific limits such as limits on percentage or timing of raises. Details about the AGA and the formula used are posted by the San Francisco Rent Board; landlords should confirm the current percentage each year before issuing notices San Francisco Rent Board - Annual General Adjustment[1].

Always confirm the Rent Board's published AGA before sending a rent increase notice.

Key legal factors landlords must check

  • Whether the unit is covered by the Rent Ordinance (coverage depends on building type and tenancy history).
  • Timing rules for increases, including required notice periods and when prior increases reset eligibility.
  • Exemptions and special rules (for example, new construction or certain single-family homes may be exempt).
  • Statutory caps such as the Annual General Adjustment that limit permitted aggregate increases for covered units.

Penalties & Enforcement

Enforcement of rent-control limits and unlawful rent increases is handled primarily through administrative petitions to the San Francisco Rent Board and, where appropriate, civil actions. Specific fine amounts for unlawful increases or related violations are not consistently published in a single place on the Rent Board's AGA page; where dollar fines or statutory penalties apply they will be set out in the governing ordinance or related enforcement guidance and may be addressed through administrative orders or court remedies San Francisco Rent Board - Annual General Adjustment[1].

  • Monetary fines: not specified on the cited page.
  • Escalation: first/repeat/continuing offence procedures and ranges are not specified on the cited page.
  • Non-monetary sanctions: administrative orders to repay overcharges, adjustment of rent ceilings, and court enforcement are typical remedies under local law.
  • Enforcer and complaint pathway: San Francisco Rent Board handles petitions and complaints; landlords and tenants can contact the Rent Board to file petitions or request enforcement.
  • Appeals and review: decisions by the Rent Board are subject to specified appeal routes and statutory time limits in ordinance or procedural rules; exact time limits are not specified on the cited AGA page.
  • Defences and discretion: permitted increases may be allowed with proper notices, justifications (such as capital improvement pass-throughs where authorized), or approved petitions; availability depends on ordinance provisions and Rent Board rules.
If you dispute an increase or suspect an overcharge, file a petition with the Rent Board promptly to preserve remedies.

Applications & Forms

The Rent Board publishes forms and instructions for petitions, owner registration, and other procedures on its website. Specific form names, numbers, and fees may appear on the Rent Board forms pages; if a form or fee amount is not listed on the AGA page, consult the Rent Board's forms and contact pages for current documents San Francisco Rent Board - Annual General Adjustment[1].
