Who needs an electrician licence in New Hampshire?

Anyone working with 30 volts or higher needs an active, valid New Hampshire electrician licence. The Electricians' Board sits within the Office of Professional Licensure and Certification and operates under RSA 319-C. New Hampshire also allows reciprocity for several trades including electricians, so a licence from another state with substantially similar requirements may be enough to obtain a New Hampshire licence without starting over. The OPLC publishes a licence lookup covering the regulated professions.

How do you check who built something in New Hampshire?

Through the permit record, because there is no general contractor registry to search. OPLC's licence lookup will confirm an electrician or a plumber, but nobody maintains a searchable roster of New Hampshire general contractors, since the state does not license them. That leaves the municipal permit file as the only public, continuous record of who has been doing work in a given town. It is also incomplete: in our own New Hampshire data, Concord records no contractor name at all across 7,526 permits, while Exeter records one on 98.6% of 1,275.

Why do some New Hampshire permits name the contractor and others do not?

Because each town decides what its permit record captures, and the choices are not consistent. Across our New Hampshire file, contractor names appear on 48.9% of building permits but only 7.0% of electrical, 3.9% of plumbing, and none at all of mechanical or trench permits. By town the split is sharper still. A missing name means the town did not record one. It says nothing about whether the person doing the work held the licence their trade requires.

New Hampshire Has No Contractor Licence

Q: Do you need a contractor licence in New Hampshire?

Not to work as a general contractor. New Hampshire issues no statewide general contractor licence, which puts it in a small minority of states and makes it one of the easiest places in the country to start a contracting business. Specific trades are a different matter. The Office of Professional Licensure and Certification supports more than 50 licensing boards, and among them the Electricians' Board licenses electricians and the Mechanical Safety and Licensing Board licenses plumbers and fuel gas fitters. So the wiring and the pipework are licensed activities. Running the job is not.

Q: Does the state building code still apply in towns with no building inspector?

Yes. Under RSA 155-A the State Building Code applies to buildings constructed in New Hampshire, but enforcement is left to municipalities and the state has no general enforcement mechanism for ordinary private homes. Plenty of small New Hampshire towns have no building inspector, issue no building permit and run no inspections, and the code still legally applies to the work. That gap between what the law requires and what any office actually checks is the single most important thing to understand about New Hampshire construction data.

TL;DR

New Hampshire issues no statewide general contractor licence. The trades are licensed.
With no registry to search, the permit file is the only public record of who builds.
Concord holds 7,526 permits and names zero contractors. Exeter names 98.6%.
The town with the best trade data has no names. The town with names has no trade data.

New Hampshire does not license general contractors. Electricians need a licence to work at 30 volts or higher, plumbers and fuel gas fitters answer to the Mechanical Safety and Licensing Board, and both sit under the Office of Professional Licensure and Certification. But the person who runs the job, hires the trades and takes the deposit needs no state credential at all.

That makes New Hampshire one of the easiest states in the country to start a contracting business, and one of the hardest to find out who your competitors are.

There is no roster to pull. OPLC supports more than 50 licensing boards and none of them is a general contractor board, so no state list exists to search. What does exist is the municipal permit record, and in New Hampshire it behaves strangely enough to be worth an article of its own. A permit is a signal about the homeowner, not the contractor, but in a state with no licensing registry it doubles as the only public trace of the contractor too.

What does New Hampshire actually license?

Trades, not builders. The distinction is sharper here than almost anywhere else in the region.

The Electricians' Board, operating under RSA 319-C within OPLC, licenses electricians, and an active valid licence is required for work at 30 volts or higher. The Mechanical Safety and Licensing Board licenses plumbers and fuel gas fitters. OPLC runs a public licence lookup covering the regulated professions, and New Hampshire allows reciprocity for several trades including electricians where another state's requirements are substantially similar.

None of that touches general contracting. No exam, no bond requirement at state level, no registration number to print on a truck.

For an operator moving into New Hampshire from a licence-heavy state, this inverts the usual playbook. Entry is cheap and fast. Differentiation is the hard part, because the credential that separates you from an unknown competitor in most states simply does not exist here. Your permit history becomes the track record, since it is the only one a customer or a general contractor can actually look up.

Why does the building code still apply where nobody checks?

Because RSA 155-A makes the State Building Code apply to buildings constructed in New Hampshire, while leaving enforcement to municipalities.

The state has no general enforcement mechanism for ordinary private homes. Many small New Hampshire towns have no building inspector, issue no building permit and perform no inspections, and the code applies to the work regardless. The New Hampshire Municipal Association has written about local administration of the state code precisely because the arrangement confuses people.

Hold those two facts together, because they explain the data. The obligation is statewide. The paperwork is not. A permit file therefore measures which towns chose to build an administrative apparatus, not where construction happens.

The current code cycle sharpens it. The updated State Building Code took effect July 1, 2026, with a concurrence period running through December 31, 2026 during which an application may follow either the 2021 or the 2024 International Code editions, and the 2024 editions become mandatory on January 1, 2027. That deadline is statewide law. The permit trail that would show anyone complying with it exists only where a town files one.

Where do contractor names actually appear?

Here is the part that surprised us. Our New Hampshire file covers four towns, and contractor naming runs almost exactly opposite to trade detail.

Town	Records	Permit types	Named contractor	Distinct names
Concord	7,526	9	0.0%	0
Hampton	2,661	5	77.2%	848
Exeter	1,275	3	98.6%	780
Seabrook	947	4	76.3%	448

Concord is our deepest New Hampshire town by a wide margin and files every one of the nine permit types we index: 3,206 building, 1,145 mechanical, 1,023 plumbing, 1,013 electrical, then sign, fire alarm, trench, gas and demolition. It names no contractor on any of them.

Exeter is the mirror image. It files 1,251 building permits, 13 gas and 11 demolition, and nothing else at all, so its trade signal is close to useless. It names a contractor on 98.6% of records, 780 distinct firms.

So the town that tells you what work is happening will not tell you who is doing it, and the town that names 780 contractors will not tell you what trade they are in. Neither town gives you both, and no amount of filtering fixes that.

Which permit types carry a name?

The same unevenness runs through the permit types, and it matters for anyone building a filter.

Permit type	Records	Named	Share
Building	7,803	3,813	48.9%
Demolition	144	41	28.5%
Gas	140	13	9.3%
Sign	583	46	7.9%
Electrical	1,093	77	7.0%
Plumbing	1,067	42	3.9%
Fire alarm	243	3	1.2%
Mechanical	1,145	0	0.0%
Trench	191	0	0.0%

Building permits are where names live, at 48.9%. Every trade permit is close to anonymous, and mechanical and trench are entirely so, which is a direct consequence of Concord being the only town that files mechanical permits at volume.

One caution worth stating plainly. A blank contractor field means the town did not record one. It is not evidence of unlicensed work, it is not evidence that no contractor was involved, and it should never be treated as either. In a state with no general contractor licence, an unnamed builder on a permit is the normal case, not a red flag.

When should you use this, and for what?

For competitive intelligence more than for lead generation, which is an unusual thing for us to say.

The Seacoast towns are the useful ones. Hampton, Exeter and Seabrook between them carry 2,036 distinct contractor names across 4,035 named permits. In a state with no licensing roster, that is the closest available approximation of who is actually working the Seacoast, and it is the sort of competitor read described in what permit data does that a purchased lead list cannot.

Use it to answer questions a licence lookup cannot. Which firms file the most building permits in Hampton. Whether a competitor has moved into Seabrook this year. Which names appear on the addition permits and which on the reroofs. None of that is available from OPLC, because OPLC does not license the people filing them.

For finding work rather than sizing rivals, Concord remains the better file, and the reasoning behind the town-by-town split is set out in how New Hampshire permit records change from town to town.

What to say in your outreach

Lead with the project and the town, as always, and be careful about what you imply regarding credentials.

Do not open by casting doubt on whoever is currently on the job. In a state that licenses no general contractors, "are they even licensed" is not a question with an answer, and asking it makes you sound like you do not know how New Hampshire works. It also lands badly with the reader, who may not be licensed either and knows it.

The stronger move is the reverse. Say what you hold, plainly. If you carry an electrician licence under RSA 319-C or a plumbing licence through the Mechanical Safety and Licensing Board, name it, because in New Hampshire that genuinely distinguishes you and most of your competitors cannot say the same thing.

Then reference the specific work. A Hampton homeowner who pulled a building permit six weeks ago is deciding on trades right now, and the permit will not tell you which ones the town does not record.

How permits.llc fits in

We index 12,409 New Hampshire permit records across 4 towns in 2 of the state's 10 counties, running from October 17, 2022 to August 19, 2026. That is a narrow file and we would rather say so than dress it up.

What it does hold: 9 permit types in Concord, a contractor name on 32.5% of records overall and on 98.6% in Exeter, addresses on essentially everything, and work descriptions that carry the trade signal in the towns where the permit type does not.

What it does not hold: coordinates, so it will not map a route for you, and any contractor name at all in Concord.

Used for the right question in the right town, it answers something no state agency can, because New Hampshire never built the registry that would have.

You can pull the New Hampshire permit records by town directly, or start from the New Hampshire county coverage to see exactly how narrow the footprint is before committing to it. New filings can also arrive by permit alert as they land, rather than being fetched.
