Who can fix it in New Jersey? Handyman and contractor license rules

Checked October 20, 2026 against New Jersey law and state agency pages · General information, not legal advice

The short answer: New Jersey has no exception for small jobs. Most businesses that fix or improve homes for pay must register with the state each year. Part-time work counts too.

“No contractor business shall offer to perform, or engage, or attempt to engage in the business of making or selling home improvements unless registered with the Division of Consumer Affairs” — N.J.S.A. 56:8-138(a), as amended by P.L. 2023, c. 237

What that means for your job

Trades that need a license in New Jersey

General building/home improvement
New Jersey has no general contractor license. Instead, most home repair firms must sign up with the state each year, even part-time ones. Some are exempt, like licensed trades working within their license. (N.J.S.A. 56:8-138(a), Contractors' Business Registration Act (as amended by P.L. 2023, c. 237); N.J.S.A. 56:8-138(b) (annual registration); Home Improvement Contractor Business - Frequently Asked Questions (side jobs); Home Improvement Contractor Business - Frequently Asked Questions (who is exempt))
Electrical
Yes. Electrical work needs a state-licensed pro. Tiny jobs, like replacing bulbs and fuses, do not. (N.J.A.C. 5:23-2.15(b)2i, Uniform Construction Code (licensed trades; homeowner exception); N.J.S.A. 45:5A-18(a) (electrical: minor repair exemption), as amended by P.L. 2021, c. 479)
Plumbing
Yes. Plumbing work needs a state-licensed pro. A homeowner may do plumbing on their own one-family home. (N.J.A.C. 5:23-2.15(b)2i, Uniform Construction Code (licensed trades; homeowner exception))
Heating and air conditioning
Yes. Heating, cooling, and refrigeration work needs a state-licensed pro. A homeowner who lives in a one-family home may do their own, except work with CFC or HCFC refrigerants. (N.J.A.C. 5:23-2.15(b)2i, Uniform Construction Code (licensed trades; homeowner exception); N.J.S.A. 45:16A-9 (HVACR: single-family homeowner), P.L. 2007, c. 211)
Roofing
Roofers must sign up with the state too, like most home repair firms. (Home Improvement Contractor Business - Frequently Asked Questions (what counts as a home improvement); N.J.S.A. 56:8-138(a), Contractors' Business Registration Act (as amended by P.L. 2023, c. 237))
