New building permits in San Mateo County, California show where construction activity is occurring. Filter the public records by trade, date, address, and project value to research active projects and property activity. Contractor names are available on some current records; contact coverage varies by filing.
San Mateo County, California processes building permits covering residential construction, commercial buildouts, renovations, and specialty trade work. PermitGrab tracks 1507+ San Mateo County building permits — newest permit date: 2026-09-16 from official city sources.
