New Hampshire General Contractor License Requirements (2026)

New Hampshire does not issue a state-level general contractor license. There is no statewide registration, no state-administered bond, and no state contractor exam for general construction. Anyone may legally hold themselves out as a general contractor in New Hampshire provided they comply with municipal building permits, hire only state-licensed electricians, plumbers, and gas fitters for those scopes, carry workers compensation if they have employees under RSA 281-A, and follow consumer protection rules under RSA 358-A. Accountability lives at the local building department and through civil contract law rather than at a state contractor board.

Regulatory Oversight

Under 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 Office of Professional Licensure and Certification (OPLC) — trade boards (OPLC) is the body that issues this license and enforces compliance with it. 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 gencourt.state.nh.us 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.

Who May Apply

At a minimum the applicant has to be 18 years old and supply a valid Social Security Number or Individual Taxpayer Identification Number (ITIN). No New Hampshire residency requirement. No state license to apply for.

Good moral character

No state contractor board fitness review. Local building departments may refuse to issue permits to contractors with documented complaint histories. The Attorney General may bring RSA 358-A consumer protection actions against contractors who engage in deceptive practices.

Background investigation

No state-level background check for general contracting. Some municipalities require contractor sign-in or registration with local police or building departments before pulling permits.

Required Experience and Education

There is no published year count for this credential in the cited sources. What actually controls eligibility is no state experience requirement for general contractors. Individual sub-trades (electrical, plumbing, gas fitting) require board-set experience independently of any general contractor role..

Accepted proof of experience or eligibility

No state proof of experience required for general contracting
Local building departments may request a project history when issuing permits to first-time applicants

Education substitution

Not applicable — no state education requirement for general contractors.

Examination Requirements

This credential carries no state-administered written exam under the cited sources. What governs instead is: No state-administered general contractor examination

Examination fee: No state exam fee.

Retake policy: Not applicable — there is no state exam.

Insurance and Financial Requirements

This credential carries no state-level surety bond requirement under the cited sources. Individual jobs may still trigger a permit or public-works bond, which should be verified before bidding.

General liability

Not required by the state for general contractors. Municipalities and project owners commonly require $500,000 to $1,000,000 per occurrence general liability before issuing permits or signing contracts.

Workers' compensation

Workers compensation insurance is mandatory under RSA 281-A for any employer with one or more employees, including part-time. The Department of Labor enforces with stop-work orders. Sole proprietors with no employees are exempt but may elect coverage.

Additional financial requirements

No state financial statement requirement. Banks and bonding companies on private projects set their own thresholds.

Licensing Fees

Fee	Amount
Application (non-refundable)	No separate state fee
Initial license	No separate state fee

Keeping the License Current

Renewal of the New Hampshire General Contractor (no state license — municipal permitting only) is not on a single statewide clock; defer to the issuing board or local jurisdiction. The cited state source set does not list a separate statewide renewal fee. There is no state license to renew. Insurance policies, business registration, and tax accounts have their own renewal cycles set by their issuing authorities.

Continuing education: No state continuing education requirement for general contractors.

Reciprocity and License Transfer

The NASCLA Accredited Examination is not accepted by New Hampshire for this classification.

Reciprocal State	Accepted Exam	Conditions
No formal bilateral reciprocity agreements identified.

No state contractor license exists, so reciprocity does not apply. Contractors licensed in other states may operate freely in New Hampshire as long as they meet local permit requirements and workers compensation rules.

Application Process, Step by Step

Register the business. Form an LLC or corporation with the New Hampshire Secretary of State, or operate as a sole proprietor under your legal name. Obtain a federal EIN.
Open state tax accounts. Register with the New Hampshire Department of Revenue Administration for Business Profits Tax and Business Enterprise Tax accounts as required by your structure and revenue.
Secure workers compensation. If you will have any employees, bind workers compensation coverage under RSA 281-A before the first hour worked. File proof with the Department of Labor on request.
Carry general liability and a vehicle policy. Although not required by the state, $1,000,000 general liability is the practical minimum for permits and contracts. Add commercial auto for any company vehicles.
Build a roster of licensed sub-trades. Identify NH-licensed electricians, plumbers, and gas fitters before bidding work. They will pull their own trade permits.
Confirm the local permitting process. Call the building department in every town you bid in. Confirm permit forms, contractor sign-in, inspection schedules, and insurance requirements before quoting any price.
Use a written contract that complies with RSA 358-A. Written contracts with clear scope, price, schedule, change orders, and a three-day cancellation notice for residential work reduce consumer protection exposure.

Document Checklist

The most critical documents or confirmations the applicant should have in hand before filing with OPLC:

☐ Business entity registered with the NH Secretary of State (or sole proprietor)
☐ Federal EIN issued by the IRS
☐ NH Department of Revenue Administration tax accounts opened where required
☐ Workers compensation policy bound under RSA 281-A (if any employees)
☐ General liability policy at a level acceptable to clients and municipalities
☐ Roster of NH-licensed electricians, plumbers, and gas fitters for sub-trades
☐ Written contract template with three-day cancellation notice for residential work

Frequent Application Errors

Drawn from the board instructions and sources cited on this page, the pitfalls below are the ones most likely to slow down or sink a New Hampshire General Contractor application.

Assuming no license means no rules

Building codes, trade licensing, workers compensation, and consumer protection law all apply. Skipping any of them invites stop-work orders, lawsuits, and criminal liability.

Hiring an unlicensed electrician or plumber

New Hampshire enforces individual trade licensing strictly. Hiring an unlicensed worker exposes the general contractor to fines and complaint actions, and any work performed will fail inspection.

Skipping workers compensation

RSA 281-A requires coverage at one employee. The Department of Labor uses unannounced site visits and stop-work orders. The fine schedule is steep and uninsured medical exposure is unlimited.

Operating without a written contract on residential work

RSA 358-A and good practice both require a clear written contract. Oral residential contracts are nearly impossible to enforce and create RSA 358-A exposure.

Treating every town the same

Permit forms, fees, contractor sign-in rules, and inspection schedules vary widely between New Hampshire municipalities. Always call the local building department before quoting work.

Questions Applicants Ask

Does New Hampshire require a state general contractor license?

No. New Hampshire is one of a small number of states with no state-issued general contractor license. Accountability runs through municipal building permits, state trade licensing for electrical, plumbing, and gas work, and consumer protection law under RSA 358-A.

Is there a state home improvement contractor registration in New Hampshire?

No. Unlike Massachusetts (HIC) or Rhode Island, New Hampshire has no state home improvement contractor registration program and no state-administered consumer recovery fund. Disputes are handled by the courts and the Attorney General Consumer Protection Bureau.

Do I need any license to build a house in New Hampshire?

You do not need a state contractor license, but you do need a building permit from the municipality, and every electrician, plumber, and gas fitter on the project must hold a current New Hampshire trade license. You also need workers compensation if you have employees.

Do out-of-state general contractors need to register in New Hampshire?

There is no state contractor registration to file. Out-of-state contractors should register the business with the Secretary of State as a foreign entity, open the appropriate tax accounts, and confirm local permit requirements in each municipality they work in.

What protects consumers if there is no state contractor license?

RSA 358-A (Consumer Protection Act) lets consumers and the Attorney General sue contractors for deceptive practices, including double damages and attorney fees. Mechanic's lien law under RSA 447 governs payment disputes. Municipalities can also withhold future permits from contractors with unresolved code violations.
