Do I need a permit for window or exterior door replacement in Idaho Falls?

Permit may be required

It depends. Whether window or exterior door replacement needs a permit in Idaho Falls comes down to the details of your project.

Idaho has no statewide building permit mandate for homes: each city or county chooses whether to run a building program (Idaho Code 39-4116(1)), so confirm with the city or county office that has jurisdiction. Idaho's amended residential energy code sets a maximum window U-factor of 0.32 in climate zone 5 and 0.30 in climate zone 6 (IDAPA 24.39.30.600.06.b). Enlarging an opening or changing a structural header is alteration work, not a like-for-like swap, and is more likely to need a permit. A permit cannot require upgrades to unaffected existing parts that complied with the code when built, unless the building official proves a specific substantial safety hazard (Idaho Code 39-4111(3)).
