New Hampshire Carpentry License Requirements (2026)

New Hampshire does not issue a statewide carpentry or general-contractor license, and it has not yet established a statewide builder-registration program. A 2026 law created a committee to study such a program, with a report due November 1, 2026; it did not create a current credential. Carpentry projects are instead governed by the State Building Code and local enforcement/permit process, any separately licensed electrical, plumbing, gas, or other trade scope, and ordinary business and employment laws. For residential construction or improvement contracts over $5,000, RSA 359-G requires a conspicuous notice describing the homeowner’s statutory defect-resolution process. This is not a blanket state license or universal written-contract rule.

Federal requirement: EPA Lead RRP Rule

Whether or not New Hampshire licenses this trade, any work that disturbs paint in pre-1978 housing falls under the federal EPA Lead RRP Rule nationwide. See our complete EPA RRP Lead Certification guide for who needs firm and renovator certification, what it costs, and how renewal works.

Who Regulates This Work

New Hampshire Office of Professional Licensure and Certification (OPLC) — trade boards (OPLC) is the primary authority or official reference used for this guide. The controlling authority cited here is New Hampshire RSA 319-C (Electricians), RSA 329-A (Plumbers), RSA 153 (Mechanical/Gas Fitters); administrative rules Elec 100–600, Plu 100–600, Saf-C 6000 series. New Hampshire does not license general contractors at the state level. Trade boards under the OPLC umbrella license individual electricians, plumbers, and gas fitters statewide. Mechanical/HVAC work intersects the Gas Fitters Board (for fuel gas piping) and local mechanical permitting; pure HVAC ductwork is not separately state-licensed. New Hampshire is unusual in the Northeast for combining strict individual trade licensing with no general contractor license at all — accountability for general construction sits at the municipal building department and through civil contract law. Home improvement contractors are not registered or bonded by the state; consumer protection runs through RSA 358-A (Consumer Protection Act) enforced by the Attorney General. Always confirm current rules with OPLC and the local building official before bidding work. Overview of the New Hampshire licensing landscape: New Hampshire takes a deliberately light-touch approach to construction trades regulation compared to its neighbors. There is no statewide general contractor license, no statewide home improvement contractor registration program (unlike Massachusetts HIC or Rhode Island contractor registration), and no statewide building permit. Instead, the state relies on three pillars. First, the building code: New Hampshire adopted the State Building Code under RSA 155-A, which incorporates the International Building Code, International Residential Code, International Mechanical Code, International Plumbing Code, International Energy Conservation Code, and the National Electrical Code by reference. The State Fire Marshal enforces the State Building Code in jurisdictions that have not adopted local enforcement, while most populated municipalities run their own building departments and issue their own permits. Second, individual trade licensing: the Electricians Board, the Plumbers Board, and the Mechanical Licensing Board (Gas Fitters) license journeyman and master tradespeople under their respective statutes. These licenses are personal to the individual and follow the worker between jobs and between employers. Third, consumer protection law: home improvement disputes are handled through RSA 358-A and standard contract law, not through a state license bond pool. What this means in practice for contractors: a self-employed builder in New Hampshire can legally bid and build a single-family home without any state-issued license, provided every electrical worker on site holds a current Electricians Board license, every plumber holds a current Plumbers Board license, every gas fitter holds a current Gas Fitters Board license, the project clears the local building department permit, and the work passes all required inspections. The contractor may still need a federal EIN, state business registration with the Secretary of State, business profits and enterprise tax accounts with the New Hampshire Department of Revenue Administration, and (if hiring) workers compensation coverage under RSA 281-A. The Department of Labor enforces workers compensation aggressively, and uninsured employers face stop-work orders. Municipal nuances matter. Manchester, Nashua, Concord, Portsmouth, Dover, and Keene each operate full building departments with their own permit application packets, contractor sign-in requirements, and inspection schedules. Some towns require the contractor to be listed on the permit; some require proof of insurance before issuing the permit; a few smaller towns have no building inspector at all and rely on the State Fire Marshal. Always call the building department before assuming a project does not need a permit. Electrical and plumbing permits are typically pulled by the licensed tradesperson, not the general contractor, and the inspection is performed by the municipal inspector or by the State Electrical or State Plumbing inspector in unincorporated areas. Reciprocity is meaningful here. The Electricians Board holds reciprocal agreements with several New England states for master and journeyman credentials, as does the Plumbers Board. The Mechanical Licensing Board recognizes equivalent gas fitter credentials from neighboring states on a case-by-case basis. Reciprocal applicants still pay New Hampshire fees, submit a New Hampshire application, and in most cases sit for the New Hampshire-specific portion or the full New Hampshire exam. Renewal cycles vary by board (electricians and plumbers renew on a three-year cycle; gas fitters renew on a two-year cycle), and continuing education requirements are set by each board. Because New Hampshire publishes most rules and forms only on the OPLC website and the General Court statute pages, contractors should bookmark oplc.nh.gov and gc.nh.gov and check both before paying any fee or scheduling an exam. Rates and fee amounts in this guide should be confirmed directly with the relevant board before submitting payment.

State and Local Eligibility Rules

There is no single statewide application for this work, so this guide does not impose a uniform applicant-age, identification, or tax-number rule. Check the business, specialty-trade, and local authorities that govern the actual project. No statewide carpentry-license application exists. Form an entity or register a trade name when the selected business structure requires it, and check the project municipality for local permit or registration rules.

State-level applicant screening

No statewide carpentry-license character standard was identified.

Background-check requirements

No uniform statewide carpentry background-check requirement was identified. Separate specialty-trade licenses or municipal programs may differ.

Experience and Scope Requirements

No single statewide year-based experience threshold governs the local or scope-specific path described here. The controlling requirement is No statewide carpentry experience requirement was identified. Experience, supervision, examination, and credentialing rules apply if the project includes a separately regulated specialty trade..

Relevant records and local documents

Business-formation or trade-name documents, if applicable
Local building-permit and inspection documents
Specialty-trade license documentation for electrical, plumbing, gas, or other regulated work
EPA RRP records or New Hampshire DHHS lead-abatement documents when applicable

Education and scope boundaries

No state carpentry education or apprenticeship substitution rule was identified because New Hampshire does not issue a statewide carpentry credential.

Testing Requirements

There is no single statewide trade examination for the local or scope-specific path described here. The applicable testing rule is: No statewide carpentry examination was identified.

Step-by-Step Compliance Roadmap

Define all work scopes. Separate carpentry from electrical, plumbing, gas, engineered-design, or other scopes that may require their own New Hampshire credential.
Set up the business as needed. Register the selected entity or trade name where required; this is not a statewide carpentry license.
Check the local authority before bidding. Municipalities with local enforcement agencies administer permits and State Building Code enforcement, and may adopt compatible local provisions.
Use a clear residential agreement. For residential construction or improvement contracts exceeding $5,000, give the conspicuous RSA 359-G defect-resolution notice. Use signed written scope, price, change-order, insurance, and warranty terms on every project as sound business practice.
Obtain permits and inspections. Follow the actual municipality’s building and fire process. Where there is no local enforcement agency, the State Fire Marshal can enforce on municipal written request.
Meet labor and lead obligations. Maintain workers’ compensation where required. For covered pre-1978 renovation, use federal EPA RRP; use New Hampshire DHHS lead credentials only when the scope is lead abatement.

Pre-Work Checklist

Before bidding or beginning work, confirm each item below with the authorities that govern the project location and scope:

Define carpentry and any separately regulated trade scope
Set up the chosen business entity or trade name as required
Confirm the project municipality’s permit and enforcement process
Use written scope and change-order terms
Include the RSA 359-G notice for qualifying residential contracts over $5,000
Maintain workers’ compensation when required
Screen pre-1978 projects for EPA RRP and distinguish lead abatement
Obtain permits and pass required inspections

Common Compliance Mistakes

The issues below are the most likely to create an unlicensed-work, registration, permit, or scope problem for New Hampshire Carpentry work, based on the official sources cited on this page.

Applying for a nonexistent statewide carpentry credential

New Hampshire has no current statewide builder registration; the 2026 measure only directs a study committee to report in November 2026.

Treating old contract thresholds as current law

The verified current statute requires the RSA 359-G defect-resolution notice for qualifying contracts over $5,000, not the obsolete general written-contract claims.

Skipping municipal approval

State Building Code enforcement and permit administration are local where a municipality has an enforcement agency.

Crossing into a specialty trade without the right credential

Carpentry does not substitute for the state credentials required for regulated electrical, plumbing, gas, or other work.

Confusing RRP with abatement

Federal RRP and New Hampshire lead abatement are distinct regulatory pathways; determine the project’s actual lead scope.

Official References and Preparation Materials

Frequently Asked Questions

Does New Hampshire require a carpentry license?

No statewide carpentry or general-contractor credential was identified. A 2026 study committee is considering a future builder-registration system, but it is not an operating registration requirement.

Does New Hampshire require a written home-improvement contract?

Do not rely on the removed $500 or $2,500 threshold claims. RSA 359-G requires a conspicuous defect-resolution notice for a qualifying residential construction or improvement contract over $5,000. Written contracts remain strongly advisable for all work.

Who issues permits for structural carpentry?

The project municipality’s local enforcement agency generally administers State Building Code enforcement and permits. Municipalities may have compatible additional provisions.

Can a carpenter perform electrical or plumbing work?

Not merely because the person is a carpenter. Electrical, plumbing, gas, and other specialty work can have separate state licensure rules; identify and staff each regulated scope appropriately.

Is lead certification required for old-home carpentry?

Covered paid renovation in pre-1978 target housing or child-occupied facilities is governed by federal EPA RRP. New Hampshire DHHS lead credentials apply to lead abatement, a distinct scope.
