PermitStack data coverage — 8,000+ U.S. cities across 48 states and DC, 117M+ building permits

Our 887 active data sources — including counties and statewide feeds — cover building permits from 8,000+ U.S. cities across 48 states and DC, sourced from official city and county permit systems and open-data portals and re-read on a nightly schedule. We label active feeds and historical archives separately, and every row carries the date its newest permit runs through, so you always know whether a city is still publishing. 287 active sources are currently marked "access blocked" (their host is refusing our requests), so their data is older than the rest.
