Licensing

New Jersey contractor license requirements

New Jersey does not issue a statewide general contractor license. Home improvement contractors register with the Division of Consumer Affairs, new home builders register with the Department of Community Affairs, and electrical, plumbing, and HVACR contractors hold trade licenses.

New Jersey has no single state license for a general contractor. What you need depends on the work. If you remodel, repair, or add on to homes, your business must register as a Home Improvement Contractor Business with the Division of Consumer Affairs. If you build new homes, you register with the Department of Community Affairs. Electrical, plumbing, and HVACR work each need a license from a state board. Commercial general contracting on private jobs has no state license, but public work brings its own registration.

Home improvement contractor registration

The state business guide for home improvement contractors puts it plainly: the Contractor's Registration Act requires all home improvement contractors to register with the Division of Consumer Affairs and display their registration number, known as the NJHIC number. That number goes on contracts, ads, and trucks. There is no trade exam for this registration. It is a business registration backed by insurance and security, not a test of skill.

The initial application, filed with the Regulated Business Section in Newark, asks for:

  • A nonrefundable $110 registration fee (duplicate certificates are $20 each).
  • Your business name as shown on your trade name certificate or Alternate Name Form C-150G, plus formation documents for an LLC or corporation.
  • A certificate of commercial general liability insurance of at least $500,000 per occurrence, with the insured name and address matching the application.
  • Proof of workers' compensation coverage, or documentation of an exemption.
  • Proof of the "additional security" required by N.J.S.A. 56:8-142.
  • An ownership disclosure statement and a signed certification by a principal officer.

If your liability or workers' comp policy is canceled or not renewed, the Division wants the replacement certificate within 10 days. Any other change to the information you filed, including the security, must be amended within 20 days. Keep a certificate of insurance calendar so a lapsed policy does not quietly put the registration at risk.

The 2024 law change: workers' comp and additional security

On January 8, 2024, P.L. 2023, c. 237 amended the registration act. The Division's notice to registrants says every home improvement and home elevation contractor business now needs three things to obtain, renew, or reinstate a registration: workers' compensation insurance unless exempt, an additional security, and commercial general liability insurance. The security can be a compliance bond from a surety authorized in New Jersey, an irrevocable bank letter of credit, or securities or money.

Minimum additional security under N.J.S.A. 56:8-142
Minimum securityApplies to
$10,000Contracts valued under $10,000, or under $150,000 of contracts in the previous 12 months
$25,000Contracts valued $10,000 to $120,000, or $150,000 to $750,000 of contracts in the previous 12 months
$50,000A contract valued over $120,000, or at least $750,000 of contracts in the previous 12 months

Say a two-truck remodeler signed $600,000 of kitchen and bath work last year, with no single job over $120,000. That lands in the $25,000 tier. Land one $140,000 addition and the minimum jumps to $50,000. Talk to your bonding company before you sign the bigger job, not after.

The same law created the Home Improvement and Home Elevation Contractor Licensing Act, N.J.S.A. 45:5AAA-1 et seq., and a new State Board of Home Improvement and Home Elevation Contractors. That act sets up individual licensing on top of business registration, phased in after the board is formed. Check the Division of Consumer Affairs for the current status before you assume business registration alone is enough.

New home builders, trades, and public work

New home builders fall under a different agency. The Department of Community Affairs says all new home builders must be registered with it, and a builder cannot obtain a permit to build a new home without first being registered. DCA publishes a list of all builders showing whether each is actively registered, suspended, revoked, or bankrupt. If a builder is not on the list, it is not currently registered.

Electrical contractors, HVACR contractors, master plumbers, fire and burglar alarm installers, and locksmiths must be licensed by a state professional board. A home improvement registration does not cover that work. A general contractor running a $480,000 tenant fit-out still needs licensed electrical and plumbing subcontractors on the job and on the permit.

Contractors and subcontractors that bid on or work on public works projects must register with the New Jersey Department of Labor and Workforce Development. The fee is $500 for one year, or $750 for two years if you have been continuously registered for the last two consecutive years with no prior violations. Applications have been online only since August 15, 2024. Public jobs also carry prevailing wage rules; see New Jersey prevailing wage.

Keeping registrations current

Most lapses are paperwork, not bad work. A policy renews with a new number and nobody sends the Division the certificate. A bond rider is not updated after a name change. Track every registration, policy, and bond with an expiration date and an owner. Smart Business Automator stores license numbers, insurance certificates, and expiration dates for your company and every sub in one place, with alerts before anything lapses. See subcontractor compliance automation. If a job goes unpaid, New Jersey lien rules are on the New Jersey mechanics lien page.
