Contact & support

TheBuildingCode is built and maintained by a small team that cares about getting the numbers right. If something looks wrong, or you want a tool we haven't built yet, we want to hear it.

Email us: support@thebuildingcode.com

What we can help with

• Report an error — if a calculator result or a code reference looks off, tell us the tool, the inputs you used, and what you expected. We fix verified issues quickly.
• Request a tool or guide — tell us the trade and the question you're trying to answer. We prioritise by how many people need it.
• Corrections & sources — if you have a code citation that improves accuracy, send it along; where an answer rests on a code rule, we name the code and edition.
• Press & partnerships — reach out at the same address.

Response time

We read every message and aim to reply within a few business days. For anything urgent or safety-critical, please consult your local Authority Having Jurisdiction (AHJ) or a licensed professional — see our disclaimer.
