The rule change behind the next wave: the Family Zoning Plan
San Francisco's Family Zoning Plan took effect on January 12, 2026, after the Board of Supervisors adopted it on December 9, 2025. It rezones parts of the city, largely in the north and west, to allow more homes along major transit and commercial corridors. The state requires San Francisco to plan for at least 82,069 new homes from 2023 to 2031, and Planning describes the rezoning target as roughly 36,000 homes.
