Building permits in San Mateo County can document new construction, renovations, and specialty work.

Use the displayed source information to evaluate whether a record is useful for your market research.
HVAC contractors, electricians, plumbers, and roofers can use San Mateo County building-permit records to research visible construction activity. A permit may signal a project that is relevant to a particular trade, but the source record does not establish that its owner is seeking a bid.
Use the published date, project details, and any named business contact to research a project before outreach. Public records are not exclusive, and outreach results depend on the market, project, and your own process.
Eligible subscribers can receive trade-filtered alerts when new records are collected. Alert timing and field coverage follow the underlying source rather than a universal schedule.
