The OpenStreetMap of Building Codes
Building codes are public law. We are building the world's largest open database of structured, machine-readable construction regulations.
Building Codes Are Public Law
Building regulations are enacted by governments for public safety. They should be freely accessible to every engineer, architect, and citizen.
Machine-Readable Standards
We transform dense legal documents into structured, queryable data that software can understand and automate against.
Community-Driven
Like OpenStreetMap, our data improves through community contributions. Engineers in every country help verify and extend coverage.
ODbL Licensed
All structured building code data is released under the Open Database License. Use it freely -- just share improvements back.
Data Coverage
Free REST API
Access all building code data through our free API. No authentication required for read-only access to public building code data.
