How to Get a Home Improvement License in New Jersey

To get a home improvement license in New Jersey, you register your business with the Division of Consumer Affairs under the Contractors’ Business Registration Act, carry the required liability insurance, and follow the state’s contract and disclosure rules once you start work.¹ A separate individual license is coming: in January 2024, Governor Murphy signed P.L. 2023, c. 237, which created the State Board of Home Improvement and Home Elevation Contractors and a new licensing statute.² As of early 2026, the Board is still developing the exam and education framework, so the registration system remains the active credential while you prepare for the individual license.

Who Has to Register

Anyone soliciting or performing residential remodeling, repair, or renovation work in New Jersey needs to register before starting. That covers remodeling, renovating, repairing, restoring, demolishing, driveways, swimming pools, porches, insulation, and even converting a commercial building into a residence. Building a brand-new home is not home improvement under the statute.³

Small operators still register. If you earn no more than $1,500 per contract and $25,000 per year from this work, registration applies, but you will not need a licensed contractor on staff once the new licensing system takes full effect.³

Some trades are exempt when working inside their own license. Architects, professional engineers, landscape architects, land surveyors, electrical contractors, master plumbers, locksmiths, and fire alarm businesses do not need a home improvement registration for work within their scope of practice.⁴ Scope matters. A licensed electrician wiring a room is exempt; the same electrician taking on a full kitchen renovation is not.

How to Register with the Division of Consumer Affairs

Initial applications go by mail. There is no online option for a first-time filing. Send the package to the Division of Consumer Affairs, Home Improvement Unit, 124 Halsey Street, 7th Floor, PO Box 46016, Newark, NJ 07101.⁵

Under N.J.A.C. 13:45A-17.5, the application must include the legal name of the business and any trade names used. You also disclose the name, residential address, and business address of every officer, director, principal, and anyone holding a 10 percent or greater ownership stake.⁶

Insurance is not optional. Every registered contractor must carry a commercial general liability policy for the entire registration term, with minimum coverage of $500,000 per occurrence, written on an occurrence form. A certificate of insurance proving current coverage has to be on file with the Division.⁷ If the policy lapses, so does the basis for your registration.

If your business has employees, is a partnership or corporation, or pays excise taxes, you will also need a federal Employer Identification Number. The IRS issues EINs at no cost through its online tool. Form your business entity with the state first, then apply for the EIN.⁸

Renewal Dates and Fees

Renewals are online and time-bound. The window opens around January 15 and closes March 30 each year, with a $90 renewal fee. Miss that window, and a late period runs through April 30 with an additional $25 fee. After April 30, your registration is expired, and getting back in requires a reinstatement application through the online system.⁵ Set a reminder in December. Reinstating an expired registration is more work than simply renewing on time.

The New Individual License Under P.L. 2023, c. 237

P.L. 2023, c. 237 did two things: it amended the old Contractors’ Registration Act, and it created a new licensing statute, the Home Improvement and Home Elevation Contractor Licensing Act (N.J.S.A. 45:5AAA-1 et seq.).¹ Once the new system is fully in effect, each contracting business will need at least one employee who holds an individual contractor license.

To qualify for that individual license, an applicant must:

Be at least 18 years old.
Show qualifying training or experience: completion of an apprenticeship program registered with the U.S. Department of Labor (or an accredited trade school equivalent), or at least two years of hands-on experience performing home improvement work under the direct oversight of a licensed contractor. Out-of-state experience counts if the Board determines the other state’s requirements are substantially equivalent.
Pass an examination and complete educational requirements the Board is developing.
Submit a criminal history disclosure as prescribed by the Board.
Pay all applicable fees.

⁹

The exam, the education framework, and the go-live date are still in development. Keep your registration current and watch the Board’s website for the licensing timeline.²

Displaying Your Registration Number

Once your number is issued, it has to appear in specific places: prominently in your place of business, on all advertisements distributed in the state, on business documents, contracts, and consumer correspondence, and on every commercial vehicle you own or lease for home improvement work.¹⁰ Website, business cards, yard signs, invoices, trucks. Every invoice, contract, or piece of correspondence given to a consumer must also carry the Division’s toll-free telephone number.

Contract and Cancellation Rules You Have to Follow

Any home improvement contract priced above $500 must be in writing and signed by all parties. The written contract has to identify the contractor’s legal name, business address, and registration number, and it has to spell out the work, the materials, the total price, and the start and completion timeline.¹⁰

Consumers can cancel for any reason before midnight of the third business day after receiving a signed copy. For consumers aged 60 or older, or consumers with an intellectual disability, the window is five business days. Cancellation must come in writing by certified or registered mail, or be delivered in person. Once you receive it, you have 30 days to refund all money paid under the contract.¹⁰

Penalties for Working Without a Registration

Operating as a home improvement contractor without a valid registration violates the New Jersey Consumer Fraud Act. The Division can revoke or suspend a registration, or impose monetary penalties instead of suspension. Consumers who hire an unregistered contractor also lose certain legal protections, which is one reason the Division maintains an online license verification tool for anyone to check status.¹

Approvals That Sit on Top of State Registration

State registration is not a substitute for a local building permit. Many projects need a construction permit from the municipality where the work happens, and applications go to the local Construction Code Enforcement Office rather than the Division of Consumer Affairs.¹¹ In most situations pulling permits is the contractor’s job, and starting work without one can bring stop-work orders and municipal fines.

Work on older homes brings a federal layer. Any contractor disturbing painted surfaces in a home built before 1978 must be certified under the EPA Renovation, Repair and Painting (RRP) program.¹² RRP certification sits on top of the state’s registration and licensing system. On a pre-1978 project you need both.
