New Hampshire has no statewide building code enforcement — permits are handled town by town, and the rules in Keene are not the rules in Swanzey or Jaffrey. But the pattern is consistent, and the short answer is: most remodels that change more than finishes need a permit.

Usually needs a permit

• Moving or removing any wall (load-bearing or not, in most towns)
• New or relocated plumbing — moving a sink, adding a bathroom, a basement bath
• New or modified electrical circuits, a panel change, most recessed-lighting jobs
• Structural work — headers, beams, deck framing, a new opening in an exterior wall
• Additions, dormers, egress windows, finished basements
• Replacing windows and exterior doors (in many towns), re-roofing (some towns)
• Any change to the building footprint or a change of use (e.g. adding a rental unit)

Usually does not

• Cabinet replacement in the same layout, countertops, backsplash
• Flooring, paint, trim, fixtures swapped one-for-one in the same location
• Like-for-like appliance swaps

"Usually" is doing work in those lists — always confirm with your town's building department, because a handful of Monadnock-region towns permit more aggressively than the norm.

How long it takes

A straightforward interior remodel permit is often issued in 1–2 weeks once the application and drawings are in. Anything needing a zoning variance, a planning board review, or shoreland/wetland approval adds 1–4 months. We build the permit timeline into the project schedule so it overlaps design instead of delaying the start.

Why it matters — and why we pull them

Unpermitted work is the thing that stalls a house sale. An appraiser or a buyer's inspector finds a bathroom that is not on the town record, and now you are retro-permitting under scrutiny, or discounting the house. As your general contractor we pull the permits under our name, schedule the inspections at each stage, and hand you the signed-off card at the end. It is part of the number, not an add-on.
