- “You've heard work done without a permit can blow up a home sale or an insurance claim later.”
What this tool does
Pick the type of work and see whether it typically needs a building permit, whether the answer depends on size or scope, and which code (IRC, NEC, IPC/UPC, IMC, IFGC, IECC) governs it. Every answer is a typical baseline; your local building department is the final authority.

What the law actually says
- •The International Residential Code, which most US jurisdictions adopt for one- and two-family homes, requires a permit to construct, enlarge, alter, repair, move, or demolish a building, unless the work is specifically exempt (IRC R105.1 and R105.2).
- •The building department with authority over your job (the Authority Having Jurisdiction) enforces the code, sets the local amendments, and has the final say on whether a permit is needed.
- •Adopted code editions and exemptions vary by state and city, so confirm the details with your local building department before you rely on a general answer.
