PermitStack

PermitStack — 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 const…

PermitStack offers (Alternative, Geospatial, Reference) — 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..

Construction-activity leading indicator at national granularity — 8,000-plus cities across 48 states and DC gives a genuine geographic panel rather than a metro sample, which is the main differentiator against the single-city vendors in this table. Asset-age and collateral-condition modeling for mortgage lenders and servicers, deriving roof, mechanical and solar system age from permit sequences. Insurance underwriting and renewal pricing off system age and recent work. Text-classification training for permit-description to trade-category mapping across many jurisdictions with varied writing conventions. Contractor capacity, market-share and credit-risk scoring from longitudinal permit volume and project value. A schema-matching and entity-resolution benchmark for data-integration systems. Regional solar adoption tracking from the roughly 11,500 NYC solar permits per year alone.
