AI-Powered Building Code Assistant for Inspectors

An offline mobile app that answers building code questions with IRC citations, local amendments, and practical field takeaways.

Build

The pain point is real: inspectors waste time flipping through paper code books and risk missing local amendments. The app solves a clear workflow problem with offline capability and one-handed use. Hard part is maintaining accurate, up-to-date local amendments across jurisdictions—requires editorial effort and trust. Distribution through certification programs and conferences is smart but slow. For this to work, inspectors must trust the AI citations over their paper books, and the editorial team must keep amendments current.
