Fresh building permits from 13 US city and regional open-data feeds, normalized into one table. Where the city publishes them, you also get the contractor's company name, and in some cities the contractor's phone or email. Filter by trade (roofing, demolition, concrete, HVAC and more), by permit type, by work class or by date range. Every row links back to the official record.
Use it to find jobs before your competitors do: roll-off dumpsters, roofing, concrete, fencing, HVAC, solar, insulation, supply sales, or any trade that follows new construction and remodels.
Coverage

Privacy
We never output property-owner, homeowner or private-individual names. Contractor and business fields appear only where the city publishes them for the contractor. Entries such as "Owner" or "Homeowner" in a contractor field are blanked.
Input

Output
One row per permit: city, state, permit_number, issued_date, date_basis, status, type, work_class, description, address, zip, lat, lon, valuation, contractor_name, contractor_phone, contractor_email, contact_name, contact_role (for example "applicant business"), source_url.
Duplicates within a run are removed. A RUN_REPORT record in the key-value store shows how many permits each city returned and kept. If one city's site is down, the others still run, and the report shows the error.
Pricing
Pay per result: $4 per 1,000 permits ($0.004 each).
