New Jersey contractor licenses: HIC registration plus licensed trades

New Jersey licenses by layers. A broad registration covers anyone who works on existing homes. Above it sit trade licenses with their own boards, and next to those are pesticide, locksmith and home inspection rules. The state also took away most of what towns used to do, so a contractor here deals with one set of statewide rules instead of a patchwork of local licenses. This page works through each layer. Everything below was read from New Jersey statutes and administrative code text in October 2026.

Home improvement contractor registration covers most residential work

The Contractors' Registration Act, N.J.S.A. 56:8-136 and following, is the rule that touches the most companies. In its text (published by the New Jersey DEP), "home improvement" means remodeling, altering, renovating, repairing, restoring, modernizing, moving, demolishing or otherwise improving or modifying all or part of residential or non-commercial property. Insulation installation is included. The Division of Consumer Affairs' registration page lists landscaping, fences, driveways, roofing and siding among the covered work.

• Annual registration. Under 56:8-138, no one may offer to perform, or engage in, the business of making or selling home improvements unless registered with the Division. Every contractor registers annually, and the director sets the fee to cover administration. Changes must be reported in an amended registration within 20 days, with no fee.
• Advertising triggers it. Section 56:8-139 says anyone who advertises in print, puts out a sign or card, or lists a name under a home improvement classification is covered. Simple alphabetical phone book listings are not.
• Out-of-state companies. Section 56:8-145 applies the act to anyone doing the regulated work in New Jersey, including those based elsewhere.
• Penalty. A violation is an unlawful practice under the state's consumer protection statute, P.L.1960, c.39, and a knowing violation is a fourth-degree crime (56:8-146).

Who is exempt from HIC registration?

Section 56:8-140 lists the exceptions. They include builders registered under the New Home Warranty and Builders' Registration Act, owners working on their own property or property owned by a family member, a charity or a nonprofit, and anyone state-regulated as an architect, professional engineer, landscape architect, land surveyor, electrical contractor or master plumber, when acting within the scope of that profession. Employees of community associations, public utilities and home improvement retailers with a net worth above $50,000,000 are also exempt. Notice that a master HVACR contractor does not appear in that list by name, although "any other person in any other related profession requiring registration, certification, or licensure by the State" may reach them. Ask the Division which category fits before you assume.

Insurance, number display and contract rules

Three more parts of the same act shape how you run jobs.

• Insurance. Section 56:8-142 requires a certificate of commercial general liability insurance of at least $500,000 per occurrence on file with the director. If the policy is cancelled or not renewed, you must file the replacement certificate before the old one ends.
• Display. Section 56:8-144 requires the registration number in your place of business, in all ads distributed in the state, on business documents, contracts and correspondence, and on commercial vehicles you own or lease for the work. Invoices, contracts and correspondence must also carry the Division's toll-free number.
• Written contract. Section 56:8-151 requires a signed written contract for any home improvement with a price above $500, and for every change to its terms. It must include your legal name, business address and registration number, a copy of the insurance certificate with the insurer's phone number, and the total price including finance charges. The consumer may cancel for any reason before midnight of the third business day after receiving a copy, and the contract must carry the notice in 10-point bold type.

Those display and contract rules reach into your website. A page that advertises home improvement should show the number, which matters if you collect quotes online. For the wider set of state rules, see our New Jersey website, phone and email rules.

Towns cannot add a contractor license

This is the most unusual New Jersey rule. Section 56:8-147 says the act supersedes any municipal ordinance that provides for licensing or registering contractors, or for protecting homeowners through bonds or warranties that contractors must provide, other than water, sewer, utility or land use rules. It also bars any municipality from issuing a construction permit for home improvement to an unregistered contractor. So the town will not make you register, but the construction office will turn you away at the permit counter if your registration has lapsed. Towns keep the power to inspect (section 56:8-148 preserves municipal inspection powers).

Electrical, plumbing and HVACR licenses

These three trades sit with boards in the Division of Consumer Affairs, and each licenses the person who runs the business.

The HVACR rule also controls how you describe yourself. Under N.J.A.C. 13:32A-5.9, no person or company may engage in HVACR contracting, advertise as a master HVACR contractor or use the title unless licensed by the Board, or unless the firm has a licensed bona fide representative. Plumbing and HVACR can share the same $3,000 bond if the applicant filed it with the plumbing board. Our guides on electrician and plumber licensing show the general path. The electrical board also posts a notice that, effective December 31, 2027, any employee working in electrical contracting must show licensure in one of four categories (Class B wireman, Class A electrical apprentice, Class A journeyman or electrical contractor), so check its page if you hire.

Pesticides, locksmiths and home inspectors

Pesticides. The DEP's Pesticide Control Code sets commercial applicator categories in N.J.A.C. 7:30-6.3. Ornamental pest control is category 3A, turf pest control is 3B (which also covers vegetation control on commercial and residential sites, and flea and tick control in turf), and structural pest control is split into 7A for general and household pests, 7B for termites and wood-destroying pests, and 7C for fumigation. A new applicator takes the Core exam plus a category exam. Operators, who apply under supervision, must be at least 18 and work under direct supervision of an applicator employed by the same employer at the same physical location (N.J.A.C. 7:30-5.1). Our pest control license guide covers how this works in other states.

Locksmiths. Under N.J.A.C. 13:31A-2.1 an applicant must be at least 18, hold a high school diploma, pass the state exam, have no first, second or third degree conviction within the prior 10 years, and show three years or 5,040 hours of hands-on experience (or a two-year approved apprenticeship). Applicants complete two hours each of training in the Barrier Free Subcode, the Uniform Construction Code, the ADA Code, industrial safety and New Jersey burglar alarm, fire alarm and locksmith law.

Home inspectors. N.J.A.C. 13:40-15.1 says no one may perform or advertise a home inspection of a building with four or fewer dwelling units unless licensed. Section 13:40-15.6 requires either 180 hours of approved study with 40 hours of unpaid field inspections or 250 fee-paid supervised inspections, a pass on the National Home Inspector Examination, and errors and omissions insurance of at least $500,000 per occurrence.

Trades with no trade license

Pressure washing, house cleaning, junk removal and lawn mowing are not trades with their own state boards. Whether HIC registration applies depends on what you do. Work that repairs, restores or improves a home, such as repainting or replacing a fence, falls under the act's definition, and the Division's page lists landscaping and driveways. If your work is pure maintenance, ask the Division before you assume you are exempt. You still need the standard business filings and sales tax setup on our New Jersey startup page, and the Division of Taxation publishes a separate contractors' tax guide.

Before you act

Treat this as general information as of October 2026, and not as legal advice. Registration fees and exemptions can change, and the act's text I read was a state-hosted copy that may not include later amendments. Confirm with the Division of Consumer Affairs before you advertise or bid. Other states are laid out side by side in our licensing boards table.
