How Contractors Use San Mateo County Permit Data

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.

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.
