San Francisco rent-change amount and date planner
Pick the regime and the planner shows only what that route supports. Ordinance: this year's allowable, the anniversary date and the licence check. State Act: 5% plus the CPI figure you enter from the state table, capped at 10%. Exempt: dates only, because no maximum exists and the planner won't invent one. Banked increases and petitions are named, never computed.

Assumptions this result depends on
- Rent is due on the 1st; the increase takes effect on a rent-due day after the notice period and the anniversary date.
- Civ. Code §827: 30 days' written notice for increases of 10% or less in 12 months; 90 days above 10%; +5 days if mailed. This calculation assumes no other increase in the preceding 12 months.
- Annual allowable increase 1.6% (SF-AAI-2026, Mar 1, 2026 – Feb 28, 2027); sf.gov › Rent Board › Current rates (fetched 29 Sep 2026). Banked increases, passthroughs and petitions are excluded.
