Do you need a permit for bathroom remodel in Dover, NH?
It depends
It depends on scope. Like-for-like cosmetic work in Dover is often exempt, but a permit is required as soon as you change structure, plumbing, electrical or the building envelope.
Dover sits in Strafford County, New Hampshire. Deep frost lines, snow load and a very old housing stock mean permits frequently touch structural, electrical and energy-code upgrades at once. Work outside city limits is permitted by the county building department rather than the city.
