Search, monitor, and act on nationwide permit data
One dataset behind a search engine, a live map, full permit records, and cross-jurisdiction contractor profiles — free to explore, with the API and exports to operationalize it.
Permit Search
Search every permit, filtered your way
Filter by jurisdiction, permit type, status, valuation, and date range across every covered municipality. Results are paginated with a stable cursor, so pages don't shift or duplicate rows as new permits land mid-scroll.
- Free to search and browse — no account required to explore
- Filter by city, permit type, status, valuation, and date range
- Cursor-stable pagination — pages don't shift as new records post
- Nationwide, cross-jurisdiction search from a single box
Interactive Map
See construction activity as it lands
Every covered permit plotted nationwide. Pan and zoom from a national view down to a single block, with density clustering at wide zoom and individual points up close — click through to the full record from any pin.
- Nationwide permit points, updated as new records land
- Density clustering at wide zoom, individual points up close
- Click any point straight through to the full permit record
- Free to browse — viewing the map never costs a lookup
Permit Detail
The full record — status, inspections, fees
Open any permit to see its complete lifecycle: application and issuance dates, valuation, applicant and contractor, full inspection history with results, and an itemized fee schedule. Search and browse are always free; opening a record's full detail costs 1 lookup, deduped per record per account per month — so coming back to the same permit later that month is free.
- 50 lookups a month on the Free plan, no card required
- 1 lookup per record, deduped monthly — revisit the same permit at no extra cost
- Full inspection history: scheduled, completed, and results
- Itemized fee schedule on every record
Contractor Profiles
One contractor, every jurisdiction they've worked in
Contractors are unified into a single cross-jurisdiction profile — every permit they've pulled, across every covered city and county, in one place. This is the differentiator: full phone and email are included on every paid tier, not gated behind an enterprise quote.
- Cross-jurisdiction contractor identity — not a per-city silo
- Full phone + email included on every paid tier
- License numbers and cross-jurisdiction permit history in one profile
- Free tier can search contractors — contact data starts at Basic
Exports
Bulk slices, delivered as compressed files
Pull filtered slices of the dataset as compressed .jsonl.zst files with signed, time-limited download links — built for bulk work, without scraping the UI or making a request per row through the API.
- 5,000 export rows/month on Basic
- 25,000 on Team · 250,000 on Pro
- Compressed .jsonl.zst delivery with signed, expiring links
- Enterprise: bulk dumps and recurring feeds
API Keys
Self-service keys, scoped and rotatable
Generate keys from your account, scope them to what you need, and rotate on your own schedule. The API draws from the same metered lookup pool as the UI, enforced server-side, with rate limits that scale by plan.
- Rate limits from 60/min on Basic up to 600/min on Pro
- Scoped keys — read:permits, read:contractors, and more
- One metered pool shared across UI and API, deduped per record
- Enterprise: SLA-backed access with webhooks
