ConstruxAi: Building Codes

ConstruxAi is an AI-powered building-code research assistant. Ask a question in plain English and get a clear, cited answer grounded in current U.S. model codes (the 2024 I-Codes and the 2023 NEC) — then tap any citation to jump to the referenced section number, title, and a supporting excerpt. Made for builders, contractors, electricians, plumbers, HVAC techs, architects, engineers, code inspectors, and informed homeowners. WHAT YOU CAN DO • Ask in natural language, like 'PEX support spacing for horizontal runs?' or 'Minimum deck ledger requirements?' • Look up sections directly, like 'IRC R507.9' or 'NEC 310.16,' with section titles, supporting excerpts, and referenced tables • Filter your search to a specific code (IBC, IRC, IPC, IMC, IFGC, IFC, IECC, and more) • See the evidence — every answer shows the sections and cross-references that support it • Ask follow-ups in a multi-turn conversation that keeps context CODES COVERED 2024 editions of the IBC, IRC, IPC, IMC, IFGC, IFC, IECC, and IEBC, plus the 2023 NEC (NFPA 70) — tens of thousands of sections, searchable in seconds.
