Where the data lives
The San Francisco Department of Building Inspection publishes building permits on DataSF, the city's official open data portal. Records include the permit type, description, address, status dates and estimated cost.
What makes San Francisco different
Older buildings mean constant alteration, seismic retrofit, re-roofing and system upgrades. Descriptions are often detailed, which makes trade matching more reliable.
Status matters
San Francisco permits move through filed, approved, issued and completed stages. Watching issued permits tells you where work is about to start.
