Handyman License Requirements in Concord, NH

By Ray Duke, Founder of Bulletproof Handyman · Last reviewed July 2026

New Hampshire has no state general contractor license requirement, making it one of the most permissive states for handymen. However, you must register as a Home Improvement Contractor with the state ($100 fee) and obtain a Concord building permit for significant work. Electrical, plumbing, HVAC, and gas fitting work absolutely require separate state licenses from the OPLC regardless of project size. Concord relies on building permits rather than a separate business license, and Merrimack County imposes no additional licensing requirements.

⚠️ What Requires a Contractor License

The following work requires a state-issued contractor license in NH. Performing this work without a license exposes you to fines, stop-work orders, and civil liability:

• Any electrical work (outlet installation, fixture changes, panel work) — requires OPLC Electrician's License
• Any plumbing work (fixture installation, pipe work, water heater replacement) — requires OPLC Plumber's License
• HVAC system installation or repair — requires OPLC Mechanical License
• Gas fitting or fuel oil work — requires OPLC Gas Fitter License
• Asbestos abatement or lead-based paint removal — requires OPLC Asbestos/Lead License
• Structural modifications or load-bearing wall work — requires licensed contractor and building permit
• Roofing work (in some jurisdictions) — verify with Concord Building Department

State Contractor Licensing Law (NH)

This freedom does NOT apply to regulated trades. Electrical work, plumbing, gas fitting, HVAC, asbestos abatement, and lead-based paint work all require separate state licenses from the OPLC regardless of project size or cost. Even a single outlet installation requires an electrician's license. Additionally, while no state contractor license is required, Concord requires building permits for work of significant scope, and you must register as a Home Improvement Contractor with the state ($100 fee) if you perform home improvement work.

Permit vs. Contractor License — The Legal Difference

A license is a credential issued by the state (or city) that authorizes you to perform a specific trade or business. A permit is a one-time approval issued by the city/town for a specific project. In New Hampshire, you do not need a state general contractor license, but you DO need a building permit from Concord for work of significant scope. Additionally, even if you are exempt from needing a contractor license, you may still need a permit for certain work. For example, a handyman can legally paint a house without a license, but if that painting involves exterior work affecting the structure or historic district, a permit may be required. The key rule: if the work requires a building permit, it almost certainly requires a licensed contractor or at minimum a permit application.

Business Entity Registration (NH)
