What it returns

Building permits from city permitting departments, in one schema: permit number, type, residential or commercial class, work class, description, status, applied, issued, completed and expiry dates, declared valuation, address, ZIP, coordinates, parcel, contractor company and housing units added.

Search by city, permit type, class, words in the description (solar, ADU, demolition, pool), status, address, ZIP, contractor, minimum valuation, new-housing permits only and issue date range, newest or largest first. Or group the matches to get counts and valuation totals by contractor, ZIP, permit type, year or month, for example the busiest solar installers in a ZIP code or new housing permitted per month.

Cities: New York City (DOB NOW and legacy BIS), Los Angeles, Chicago, Seattle, Austin, San Francisco and Philadelphia, more added as cities publish open permit data. Rebuilt weekly from each city's open data portal. Owner and applicant personal names are not included; contractor business names are.

Charged per permit or total returned.
