San Francisco Building Permits — October 2026
Every building permit issued by the City and County of San Francisco in October 2026: counts, reported value, permits by trade, and the month's biggest projects.
Source: San Francisco open data (DataSF) — building permits issued by the Department of Building Inspection. Source last updated: October 17, 2026 · Our last pull: October 18, 2026 · Figures are as reported by the City and County of San Francisco.
Coverage: this report covers building permits issued by the City and County of San Francisco (a consolidated city-county, so the feed covers the whole county). One counting rule matters here: San Francisco's Department of Building Inspection publishes one row for every address or lot a permit touches, so one permit can appear several times in the raw feed. We count each permit once, at the address the department flags as primary — counts on this page are permits, never raw feed rows.
Month to date: figures run through October 16, 2026, the latest date in the source data as of our October 18, 2026 pull.
