Trades that need a licence in New Jersey
General contracting and renovation
Home improvement contractors are registered with the state: the Division of Consumer Affairs verification system lists home improvement business contractors alongside electrical business permits and master plumbers, so you can check a business before you hire it. Some cities also register contractors that hold no state licence.

General contracting and renovation
New Jersey's code is statewide but enforcement is local: the Department investigates alleged violations and reviews local budgets, while it issues permits itself only for state buildings and for municipalities that have asked it to take over enforcement.

The state code is built from subcodes, each adopted separately: the building and residential subcodes follow the 2024 International Codes, plumbing the 2024 National Standard Plumbing Code, and the electrical subcode the 2023 National Electrical Code. Ask your construction official which subcode governs your work.

Building and renovation permits in New Jersey
Permits are issued by your municipality's construction official, not by the state: in Jersey City the Division of the Construction Code Official handles centralized permit issuing and inspections, and in Newark construction permits are issued by the Department of Engineering.
