New Hampshire Contractor License Requirements
infoNo State License — Local / County OnlyNew Hampshire does not require a state-level general contractor license. Local jurisdictions handle contractor registration. Electrical and plumbing require state-level licensing.
gavelHow Contractor Licensing Works in New Hampshire
New Hampshire leaves general contracting unregulated at the state level — no board, no exam, no registration for builders and remodelers. State licensing exists only for the trades: electricians go through the Joint Board of Electricians and plumbers through the state Plumbers Board, both on all work. That makes New Hampshire one of the lighter-touch states in New England, a sharp contrast with Rhode Island, where every contractor must register with a state board before working. For a contractor moving in, the shift is cultural as much as legal: your reputation, insurance certificates, and local permit history do the vetting a license would otherwise do.
Set up the fundamentals: register the business with the state, carry workers compensation if you employ anyone, and keep liability coverage current, since towns and clients will ask for proof even without a state mandate. From there, compliance is a permitting exercise — each town or city issues its own building permits and may layer on registration requirements, so check with the local building department before starting work. The trap that catches newcomers is treating the absence of a general contractor license as an absence of rules: unpermitted work, uninsured crews, and unlicensed electrical or plumbing subs all create liability that no light regulatory climate protects you from.

helpFrequently Asked Questions
Do I need a contractor license in New Hampshire?
Not for general contracting — New Hampshire has no state general contractor license or registration. Electrical and plumbing work are different: both require state licenses on all jobs, through the Joint Board of Electricians and the state Plumbers Board respectively. Local jurisdictions handle building permits and any town-level contractor requirements.
Can I do my own electrical or plumbing work as a GC in New Hampshire?
Not without the state trade license. Even though general contracting is unlicensed, electrical work requires a Joint Board of Electricians license and plumbing requires a Plumbers Board license on all work. General contractors typically subcontract these trades to licensed professionals; performing them unlicensed exposes you to enforcement and voids inspection sign-offs.
What should out-of-state contractors know before working in New Hampshire?
There is no state general contractor license to transfer or apply for, so your home-state credential is neither required nor recognized — it simply does not apply. Register your business with the state, secure workers compensation if you have employees, and confirm permit and registration rules with each town's building department before bidding.
How quickly can I start contracting in New Hampshire?
Faster than in most states. With no license application, exam, or board review for general work, your timeline is business registration, insurance binding, and local permit approval — typically days to a couple of weeks. Trade work is slower: state electrical and plumbing licenses involve their own board processes and cannot be skipped.
