How it works

5-stage daily pipeline.

Permit data starts as free-text descriptions in city open-data portals. By the time it lands in your API query, it's normalized, classified against an IBC cohort taxonomy, DQ-flagged at the cell level, and parcel-joined where source data permits.

How PermitCore compares.

Direct comparisons, calibrated honestly. Each competitor has real strengths; PermitCore picks specific axes (cohort precision · refresh cadence · DQ flag transparency · developer experience) where we go deeper.

vs PermitStack25 metros indexed today (PermitStack: 22–54 cities depending on which page); plus field-level DQ flags + NYC PLUTO geometry that PermitStack does not ship.
vs ShovelsDaily refresh vs Shovels' 1st-and-15th cadence; $49 entry vs Shovels' $599 floor; same MCP server table stakes.
vs BatchDataPermit-native, not property-native. IBC cohort precision at 18 cohorts vs BatchData's generic permit add-on; $49 entry vs $2,250 effective minimum with permits.
vs Construction MonitorAPI-first + daily refresh vs Construction Monitor's WooCommerce + weekly contractor-lead newsletter format. Different segment; CM customers upgrade to PermitCore when they want dev access.
vs Dodge / ConstructConnectWe don't compete on pre-permit research-call intel — that's their moat. We compete on permit-layer breadth + daily refresh + cohort precision at 1/10 the price for building-product manufacturers.
For who

4 ICP cohorts get specific lift.

PermitCore is built for developers who need permit data programmatically. These four cohorts get the most leverage from our API + cohort taxonomy.
