Construction & Contracting in New Jersey

New Jersey gives homeowners an unusually sharp tool, and most never use it. A home improvement job over five hundred dollars has to be in writing, and a contractor who skips the written contract has committed an unlawful practice under the Consumer Fraud Act. That statute awards threefold damages and attorney fees, so the paperwork you sign in New Jersey is doing more work than it looks like.

What New Jersey changes about hiring a contractor

Two rules do most of the work. First, registration: N.J.S.A. 56:8-138(a) says no contractor business shall offer to perform, or engage in the business of making or selling home improvements, unless registered with the Division of Consumer Affairs. A registration number is a thing you can ask for and check.

Second, the writing requirement. N.J.S.A. 56:8-151(a) provides that every home improvement contract for a purchase price in excess of five hundred dollars, and all changes to its terms, shall be in writing. The regulation at N.J.A.C. 13:45A-16.2(a)12 spells out what has to be in it: the seller’s legal name and business address including the sales representative who solicited the job, a description of the work with the make, model and capacity of principal products, the total price including finance charges, the dates or period within which work begins and finishes, any security interest, and any guarantee or warranty. The statute also gives a three business day right to cancel, with a refund due within thirty days.

What makes this bite is N.J.S.A. 56:8-146(a), which declares it an unlawful practice to violate any provision of that act. An unlawful practice is a Consumer Fraud Act violation, and under N.J.S.A. 56:8-19 a court shall award threefold the damages sustained, plus reasonable attorney fees, filing fees and costs of suit. No proof of intent is needed.

New Jersey’s contractor rules have been amended in recent years and further changes to individual licensing were still working through the process when this page was written. Confirm current requirements with the Division of Consumer Affairs.

How to choose a contractor in New Jersey

The registration check and the contract review take about fifteen minutes between them, and they are the two steps that separate a recoverable dispute from an unrecoverable one.

  • Ask for the New Jersey Division of Consumer Affairs registration number and verify it yourself rather than accepting a number printed on a truck.
  • Ask for the certificate of commercial general liability insurance direct from the insurer or agent, not a photocopy from the contractor.
  • Insist on the written contract for anything over five hundred dollars, and on written change orders for every alteration afterwards.
  • Check that the contract names start and completion dates. That element is required by regulation and it is the one most often left blank.
  • Confirm the make, model and capacity of major items — the furnace, the windows, the roofing — appear in the contract rather than a generic category.
  • Ask who pulls the permit. In New Jersey the contractor normally does, and a request that you pull it yourself as the homeowner shifts liability onto you.
  • Structure the payments so the final instalment falls due after the municipal inspection passes, not at substantial completion.

Questions to ask before you sign

  • What is your Division of Consumer Affairs registration number?
  • When does work start and when does it finish, and will those dates be in the contract?
  • Which specific products are you installing, by make and model?
  • Who pulls the permits and schedules the municipal inspections?
  • How are change orders priced and approved once work is under way?
  • What is the payment schedule, and what is held back until final inspection?

This page is general information, not legal advice. New Jersey’s contractor statutes and regulations have been amended repeatedly, so verify the current text and registration requirements with the New Jersey Division of Consumer Affairs before you rely on anything here.

Common questions

Does a home improvement contract have to be in writing in New Jersey?

Yes, above five hundred dollars. N.J.S.A. 56:8-151(a) requires every home improvement contract for a purchase price in excess of $500, and all changes to its terms, to be in writing. The regulation at N.J.A.C. 13:45A-16.2(a)12 lists what the writing must contain, including start and completion dates and the make and model of principal products.

What happens if a New Jersey contractor works without a written contract?

N.J.S.A. 56:8-146(a) makes it an unlawful practice to violate any provision of the home improvement act, which puts it inside the Consumer Fraud Act. Under N.J.S.A. 56:8-19 a court shall award threefold the damages sustained plus reasonable attorney fees, filing fees and costs. You still have to prove an ascertainable loss, so keep records, photographs and every payment receipt.

Can I cancel a signed home improvement contract in New Jersey?

N.J.S.A. 56:8-151(b) gives a three business day right to cancel, with any refund due within thirty days, and requires the contract to carry a notice of that right in bold type. Cancel in writing and keep proof of when you sent it.

Do New Jersey contractors have to be registered?

N.J.S.A. 56:8-138(a) requires a contractor business to be registered with the Division of Consumer Affairs before it offers or performs home improvements. Ask for the registration number and check it against the Division's own records rather than taking the number on faith.
