What the job involves
Most replacements are a tank of the same size and fuel. Changing size, switching from gas to electric or going tankless adds work: new gas or electric lines, venting changes or a bigger flue.
In New Jersey a like-capacity replacement counts as minor work under the Uniform Construction Code. The plumber notifies the construction office, files the permit application within five business days, and the job is inspected afterward.

Who can do this work
Plumbing work in New Jersey must be done by people licensed under the plumbing licensing law. A plumbing company has to act through a bona fide representative, a licensed master plumber who owns at least 10% of the business (N.J.S.A. 45:14C-2). That representative must make sure permits are obtained, and a licensed master plumber must sign every permit. The representative also supervises the company’s journeymen and apprentices (N.J.A.C. 13:32-3.3). Both sides of the company’s vehicles, plus its invoices, stationery and ads, must show the master plumber’s name and “Plumbing Lic. #” (N.J.A.C. 13:32-3.1). Master plumbers working within their license are exempt from Home Improvement Contractor registration (N.J.S.A. 56:8-140). To verify, use the license lookup (Person Search, profession “Master Plumbers”).
How fast can someone come?
Standard tank installation takes 1 to 3 hours (tankless 4 to 6 hours). (This Old House, 2026)

Common questions
Do I need a permit to replace a water heater in New Jersey?
Yes. Replacing an existing water heater with a new one of like capacity is “minor work” under the Uniform Construction Code. It needs a permit, but the work can begin once the plumber notifies your town’s construction office, as long as the permit application follows within five business days. The work still has to be inspected, and the construction official issues a certificate of approval afterward. (Source)
How do I verify a plumber’s license in New Jersey?
Use the Division of Consumer Affairs license verification site. Choose Person Search and the profession “Master Plumbers”, then search by name, license number or city. Board rules require plumbing companies to put the master plumber’s name and “Plumbing Lic. #” on their vehicles, invoices and advertising. Check that this number matches the lookup and is active.

Can a handyman or general contractor do plumbing work in NJ?
No, unless they hold a plumbing license. The Uniform Construction Code says plumbing work may be done only by people licensed to do it under state law. The one exception is a single-family homeowner working on their own home. The licensed plumbing contractor’s seal and signature must be on the plumbing permit application, so a remodeler needs a licensed plumber for the plumbing portion. (Source)
