Handyman License Requirements in Nashua, NH

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

For handymen in Nashua (Hillsborough County), New Hampshire generally does NOT have a statewide “general contractor” license for basic handyman/general repair work, but NH DOES license specific trades (electrical, plumbing, HVAC/gas-fitting) and local building permits still apply. There is no statewide dollar-threshold “handyman exemption” license—your limits come from (1) whether the work is a licensed trade and (2) whether a permit is required by Nashua for the scope of work.

⚠️ 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:

• Electrical work requiring a NH electrician license: new circuits, outlets/switches beyond like-for-like device replacement in many cases, panel/service work, generator interconnections, hardwired smoke/CO systems (when required by code), and most wiring in walls/ceilings
• Plumbing work requiring a NH plumber license: installing/replacing water heaters (often permit/inspection), running new supply/drain/vent lines, modifying traps/vents, tying into building drains, many shower/tub valve replacements if piping is altered
• HVAC/refrigeration work requiring appropriate licensing and (for refrigerants) EPA 608 certification: installing/servicing condensers/evaporators, charging refrigerant, major ducted system work
• Fuel gas work (natural gas/propane): installing/altering gas piping, appliance connections beyond simple listed connector swaps where permitted, combustion venting changes—typically requires licensed gas fitter/HVAC and inspections
• Structural work: removing/altering load-bearing walls, framing changes, most deck construction, additions—typically requires building permit and plans/engineering
• Roofing/siding/window/door replacements that change openings or impact egress/structural components: typically requires permits and inspections
• Lead-based paint activities in pre-1978 housing/child-occupied facilities: EPA Renovation, Repair and Painting (RRP) firm certification and trained renovators are required for many disturbance scopes

State Contractor Licensing Law (NH)

Even without a state contractor license, you must comply with: (1) state trade licensing for electrical/plumbing/HVAC/gas work, (2) local permits/inspections (Nashua Building Safety), and (3) consumer protection/unfair trade practice laws and written-contract best practices. Some projects may trigger state building code requirements and local inspections.

County Requirements — Hillsborough County

Business license: Not required at the county level.

Special Jurisdictions & Zones

The following special jurisdictions may have separate licensing requirements:

• Hanscom Air Force Base (Hanscom AFB) – Bedford, MA (within ~50 miles) — For any federal work, confirm whether Davis-Bacon wage rules apply (common on federal construction).
• Nashua Downtown Historic District (local historic district) — Even small exterior changes (replacing windows/doors) can trigger historic review in some districts.
• Qualified Opportunity Zones (QOZ) – Nashua census tracts (federal tax incentive areas) — If you bid on projects tied to public incentives, expect more documentation/insurance requirements.

City Business License — Nashua

Not required at the city level.

Permit vs. Contractor License — The Legal Difference

A license is a credential issued by the state (or sometimes a city) to legally perform a regulated trade (like electrical or plumbing). A permit is project-specific approval issued by Nashua (Building Safety) to perform regulated construction work at a specific address, followed by inspections. Even if you do not need a state license for general handyman work, you may still need a city permit for the project scope.

Business Entity Registration (NH)

To operate legally you must register your business. LLC filing fee in NH: $100 (one-time).

Compliance Notes for Nashua, New Hampshire

• Insurance: New Hampshire does not require general liability insurance by default for a handyman, but many customers and GCs require it (commonly $1M per occurrence / $2M aggregate). If you hire employees, you generally must carry workers’ compensation insurance.
• Contracts/consumer protection: Use written estimates and change orders; NH consumer protection laws can apply to home service transactions—keep clear documentation and avoid time-and-materials surprises.
• Permits: A common compliance failure is doing permit-required work “as a handyman.” Nashua can require permits/inspections even when no state contractor license exists.
• Trade boundaries: Do not advertise or perform electrical/plumbing/HVAC/gas work without proper NH licensure; misrepresentation can trigger enforcement and civil liability.
• Older homes: Pre-1978 paint can trigger EPA RRP compliance for renovation/disturbance; confirm before sanding/scraping/demolition.

Legal Registration Steps for Nashua

Follow these steps to operate legally as a handyman in Nashua, New Hampshire:

1. Step 1: Register your business entity (LLC recommended) with the NH Secretary of State (LLC filing fee $100).
2. Step 2: Confirm Nashua zoning/home occupation rules (if operating from home) and confirm permit requirements with Nashua Building Safety before starting projects.
3. Step 3: Get general liability insurance and (if you will have employees) workers’ compensation; align limits with what local GCs/property managers require.
