Verify before you build. Figures reference the 2021 International Residential Code (IRC), the National Electrical Code (NEC 2023), and NKBA planning guidelines. States and municipalities adopt different editions and pass local amendments — Utah, Washington, and Idaho each amend the IRC — so always confirm the locally adopted code and any amendments with the Authority Having Jurisdiction before permitting or construction. Manufacturer installation instructions govern appliance and fixture clearances. This guide supports design planning; it is not a substitute for a licensed contractor, engineer, or code official.
