Commercial construction permit data, daily-refreshed.

Built for PropTech, insurance, and materials teams who need fresh data, not stale aggregations.

What we're building

A normalized, geocoded permit data API spanning the largest US commercial construction markets. Daily refresh. Change-feed for real-time integration. LLM-extracted structured fields including unit count, scope summaries, and tenant improvement flags.

Currently covering NYC, San Francisco, Chicago, Los Angeles, Boston, Seattle, Austin, San Antonio, and Fort Worth — with more US metros launching through 2026.
