San Francisco rezonings
Every zoning map amendment the Board of Supervisors has enacted since 1999, read from the Planning Department's record and the Board's ordinances, mapped to the parcels each one named, and searchable by district, sheet, direction and year.
What the record will hold
- The parcels each ordinance named, block and lot by block and lot, from the Planning Department's record of the application and the parcel outline it drew.
- The zoning district before and after, read from the ordinance's own table of superseded and approved districts, the way Chicago's are read from the ordinance clause.
- Which of the City's three maps changed: the use district, the height and bulk district, or a special use district, since San Francisco draws them on separate sheets and one ordinance may revise one, two or all three.
- The Board's file number, the enactment number, the ordinance and the date it took effect.
- Applications withdrawn, cancelled or still under review, each marked by its status, alongside what the Board enacted.
- A direction for each change on two dials, kept apart as the Planning Code keeps them: the floor area ratio of Table 124, and the height limit in feet.
San Francisco enacts between three and sixteen zoning map ordinances a year, most of them special use districts written into the Planning Code and drawn on the map in the same ordinance; the Family Zoning Plan of 2026 rezoned much of the north and west side in one. The Department's record of applications runs back to 1977, so the record is read by the ordinance and the neighbourhood rather than the lot.
