The short version: New Hampshire has no statewide general contractor license and no home improvement registration, in keeping with its light-regulation tradition. The skilled trades are the exception: electricians and plumbers are licensed by the Office of Professional Licensure and Certification (OPLC), verifiable at oplc.nh.gov. Because there is no general license to check, lean hard on a written contract and the Consumer Protection Act, which doubles or triples your damages for a willful violation.

New Hampshire has no statewide contractor license

Start here, because it surprises most homeowners: New Hampshire does not issue a statewide general contractor license or a home improvement contractor registration.1 That is by design; the state leans on local control and consumer law rather than licensing.

For a senior, this changes your homework. You cannot rely on a single state lookup the way you can in California or Hawaii. You verify the trade licenses, check your town’s rules, and lean on a detailed written contract and the Consumer Protection Act.

The trades: electricians and plumbers (OPLC)

New Hampshire does license the skilled trades statewide. The Office of Professional Licensure and Certification (OPLC) licenses electricians, plumbers, gas fitters, and related trades.1 A general contractor cannot legally do their own electrical or plumbing work without that separate license.

To verify: use the OPLC license lookup at oplc.nh.gov. Search by name or license number, and confirm the license is active. If your project includes new wiring for a stair lift or plumbing for a curbless shower, verify the trade license before any work starts.

Local rules vary

For general remodeling, additions, and roofing, New Hampshire’s tradition of local governance means the rules vary from town to town.1 Some towns require a local contractor registration; most simply require a building permit.

Ask your contractor which town rules apply, and confirm the permit is pulled with your town office. A contractor who pulls permits has a paper trail and a reason to finish the job right.

Your protection: the Consumer Protection Act

Because there is no general license to lean on, New Hampshire’s protection lives in a strong consumer law. The Consumer Protection Act (RSA 358-A), enforced by the Attorney General’s Consumer Protection and Antitrust Bureau, bans unfair and deceptive practices, including home repair fraud.2

What it gives you: a harmed homeowner can recover actual damages or a $1,000 minimum, whichever is greater, and those damages are doubled or tripled for a willful or knowing violation, plus attorney fees.3 That multiplier is real leverage against a contractor who takes a deposit and disappears or lies about being licensed.

New Hampshire also gives you a three-day right to cancel a sale made at your home, and a home repair statute (RSA 359-K) aimed at storm-chasers. Get scope, materials, total price, and dates in writing before any deposit, and pay by check or card, never cash.

New Hampshire senior scam patterns

  • Post-storm roofers and tree crews After nor’easters and ice storms, out-of-state crews work hard-hit towns door to door, take deposits or insurance money, and disappear.
  • Harder to screen With no general contractor license to check, these crews are harder to vet, so verification and a written contract matter more here than in most states.
  • Insurance-claim steering Crews that push you to sign over your claim. Keep control of your own money.
  • Your defenses the OPLC trade lookup, the Consumer Protection Act with its double and triple damages, and the three-day cancellation right.2

If something goes wrong

  • Electrical or plumbing problems: file with the OPLC at oplc.nh.gov, which can discipline the trade license.
  • General contractor fraud: New Hampshire Attorney General’s Consumer Protection and Antitrust Bureau at doj.nh.gov.
  • Elder financial abuse: contact local law enforcement and Adult Protective Services.
