Introduction
The Permit Data API pulls building and construction permit records from fragmented government data sources, normalizes every record into one clean, consistent schema, and serves them through a REST API.
What it does
- Connects to government open-data feeds, web portals, and document archives to retrieve raw permit records.
- Normalizes every record — regardless of source format — into a single, predictable JSON schema so you never need to handle jurisdiction-specific quirks.
- Serves the data through a straightforward REST endpoint with filtering and pagination.
Current coverage
The API currently covers 5 live jurisdictions: Austin, TX, Chicago, IL, San Francisco, CA, Seattle, WA, and Raleigh, NC. Additional jurisdictions are added over time — the schema stays the same across all of them.
