Bathroom Remodel · Sullivan County, New Hampshire
Depends on scope
In New Hampshire, whether a Bathroom Remodel needs a permit depends on the scope of the work.
Whether a bathroom remodel needs a permit depends on the scope. Cosmetic work (new tile, flooring, paint, a vanity swap, or replacing a faucet, toilet, or fixture in place without touching the shutoff valves or trap) generally needs no permit. Moving or adding plumbing (relocating the toilet, sink, or shower, or a tub-to-shower conversion), new electrical circuits, an exhaust fan vented outside, or removing a wall each require the matching plumbing, electrical, mechanical, or building permit. Confirm which permits your project triggers with Sullivan County Commissioner.

Yes. New Hampshire generally allows property owners to act as their own general contractor under an Owner-Builder exemption. If you take this route, you assume full legal and financial liability and must ensure all work complies with the New Hampshire State Building Code.
