Handyman License Requirements in Dover, NH

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

New Hampshire has no state-level general contractor license requirement, making it one of the most permissive states for handymen. However, specific trades (electrical, plumbing, gas fitting) require state licenses regardless of job value. Dover does not impose a separate city business license on contractors; instead, you must register your LLC with the NH Secretary of State ($100 filing fee) and pull building permits for covered work through Dover's online portal. Any home improvement project over $500 requires a written contract under RSA 359-G.

⚠️ 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 beyond changing light bulbs or simple fixture replacement (requires NH Electrician license)
Any plumbing work beyond simple fixture replacement (requires NH Plumber license)
HVAC system installation or repair involving fuel gas (requires NH Fuel Gas Service Technician license)
Well drilling or water system work (requires NH Well Driller license)
Any work affecting electrical panels, circuits, or wiring (requires Electrician license)
Any work on gas lines, water lines, or drainage systems (requires Plumber license)
HVAC system work involving refrigerants or fuel gas (requires appropriate state license)

State Contractor Licensing Law (NH)

The exemption does NOT cover licensed trades: electrical work, plumbing beyond simple fixture replacement, HVAC/fuel-gas work, or well drilling all require state trade licenses regardless of job value or exemption status. Handymen must also comply with local building permit requirements and zoning ordinances.

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 profession. A permit is a document issued by the local building department that authorizes a specific project to proceed. In New Hampshire, you do not need a state general contractor license, but you DO need state trade licenses for electrical, plumbing, and HVAC work. Additionally, even exempt handymen must obtain building permits from Dover for covered work before starting. Permits are project-specific; licenses are credential-specific. You can be fully licensed but still need a permit for each job. Conversely, you can be exempt from licensing but still need a permit.

Business Entity Registration (NH)
