New Jersey requires home improvement contractor registration through the Division of Consumer Affairs. No exam is required for registration, but contractors must carry general liability insurance. Commercial contractors are not required to register at the state level. Electricians and plumbers need separate state licenses.

Never hire a contractor who cannot provide a valid license number. A legitimate contractor will have no hesitation sharing their license credentials for you to verify independently. If a contractor refuses, discourages you from checking, or makes excuses, treat that as a serious red flag.

Hiring an unlicensed contractor in New Jersey carries significant risks for both the homeowner and the contractor:

• No consumer protections: State recovery funds and guaranty programs typically only cover work performed by licensed contractors.
• Insurance issues: Your homeowner's insurance may deny claims related to work done by an unlicensed contractor.
• Permit problems: Building permits often require a valid contractor license. Work done without permits can create issues when selling your property.
• Quality concerns: Licensed contractors have demonstrated minimum competency through exams, experience requirements, or both.
• Legal liability: Homeowners may bear greater legal responsibility for injuries or property damage caused during unlicensed work.
• Penalties: In New Jersey, unlicensed contracting can result in fines and criminal penalties for the contractor, and the homeowner may lose the ability to enforce the contract.

New Jersey does not currently have reciprocal contractor licensing agreements with other states.
