New Hampshire — How to Check a Contractor's License

New Hampshire does not require a state-level general contractor license. However, this doesn't mean contractors can operate without any oversight. Many cities and counties in New Hampshire have their own licensing requirements, and specialty trades (plumbing, electrical, HVAC) typically require state licensing even when general contracting doesn't.

No state GC license. Electrical, plumbing, and asbestos/lead abatement are licensed at state level. Manchester has special requirements. Pure local jurisdiction for GCs.

How to Verify a Contractor in New Hampshire

Since New Hampshire doesn't have statewide licensing, you'll need to:

1. Check local requirements. Contact your city or county building department to find out if contractors need a local license, permit, or registration to work in your area.
2. Verify specialty licenses. If your project involves plumbing, electrical, HVAC, or other specialty trades, those contractors should hold state-issued specialty licenses. Check the No state board for GCs for specialty license verification.
3. Ask for proof of insurance. Even without a licensing requirement, any reputable contractor should carry general liability insurance and workers' compensation insurance. Ask for certificates before signing a contract.
4. Check the Better Business Bureau. In states without licensing boards, the BBB and online reviews are your primary tools for vetting contractors.
5. Verify business registration. Check that the contractor is registered as a business with the New Hampshire Secretary of State.

Protecting Yourself Without State Licensing

In states like New Hampshire where there's no state licensing board to file complaints with, it's especially important to:

• Get a detailed written contract before any work begins
• Never pay more than 10-30% upfront
• Verify the contractor pulls all required building permits
• Get multiple bids and check references
• Use a credit card for payments when possible (chargeback protection)

Should New Hampshire Require Contractor Licensing?

States without contractor licensing consistently have higher rates of consumer complaints about home improvement fraud. Licensed states provide consumers with surety bond protection, complaint investigation, and disciplinary enforcement that unlicensed states lack. If you're in New Hampshire, consider advocating for statewide contractor licensing through your state legislature.
