Do you need a permit for bathroom remodel in Boise, ID?

It depends

It depends on scope. Like-for-like cosmetic work in Boise is often exempt, but a permit is required as soon as you change structure, plumbing, electrical or the building envelope.

Fast population growth has tightened contractor availability, and wildfire-adjacent foothill neighborhoods carry additional material expectations.
