A nationwide normalized building-permit corpus served as a developer API

PERMITSTACKA5 · direct accessManage supplier listing

A nationwide normalized building-permit corpus served as a developer API. Permits are ingested daily from city and county open-data and permit portals (in NYC's case the official Tyler Data & Insights / Socrata permit-issuance system), deduplicated and mapped into one schema, then exposed by address, contractor, category and date. The NYC slice alone indexes 5,778,487 permits with 234,429 issued in the trailing 12 months and 19,794 in the trailing 30 days, categorized across plumbing, electrical, renovation, interior remodel, mechanical, solar, HVAC, fence, roofing and new construction. Derived assets include per-address property history (roof, HVAC, solar, additions with dates and contractors in one endpoint call), contractor profiles with license, specialties, permit counts and first and last permit dates, a filing-to-issuance latency statistic (NYC median roughly 19 days), and a change feed plus webhooks on higher tiers.

Dataset card

Type: not stated
Format: Tabular — JSON over REST API with a published OpenAPI specification, bulk CSV ZIP exports sold per jurisdiction, webhooks and a change-feed endpoint for incremental sync
Volume: 5,778,487 NYC permits on this page, growing at 234,429 per year with 19,794 in the trailing 30 days, up 5% year over year. Nationwide the vendor's claims are inconsistent across its own pages — the homepage headline reads 110M+ permits while the about page states 3M+ permits from 8,000-plus cities across 48 states and DC. The NYC figure alone exceeds the lower national claim, so the corpus is at minimum several million and plausibly tens of millions nationally. Treat the national total as unverified until reconciled.
Users: ~200-2,000 accounts (inferred: self-serve signup with published pricing, no sales calls, and a permanent free tier of 100 requests per day that is explicitly not a trial, so the base is a long tail of hobbyist and developer signups beneath a small paid core; the vendor publishes no account figure)
History: not stated
Update frequency: not stated
Growth: Active — nightly ingest with the latest permit dated 30 September 2026, daily refresh across the estate, and trailing-30-day volume up 5% against the same period a year prior; offset by the product being only months old since an April 2026 launch, so growth is ramp-up rather than maturity
Launched: April 2026 — stated directly on the about page, so the service is roughly six months old as of October 2026
