US Building Permits API

Permit history for US properties and contractors.

About this API

Permit data is useful for property due diligence, contractor lead generation, insurance underwriting and solar/roofing qualification. This API normalizes a messy local-government dataset into a consistent permit event.

The preview returns a clearly labelled sample for a small set of cities. Production connects to local open-data feeds and normalizes them behind the same shape. Each record includes a source URL and a `retrieved_at` timestamp.

For AI agents

Look up sample US building permit records by city and optional search text.

Scope

Sample cities only. Not a complete national permit feed, legal verification or construction approval.
