What makes an application complete
The application has to name the licensed electrical and plumbing contractors doing that work and the home improvement contractor's registration (N.J.A.C. 5:23-2.15). The 20 business days run on a complete application, so missing drawings or trade information restart the wait.
During the job
Work stops at each required inspection, such as rough plumbing and wiring before the walls close, and the town performs an inspection within three business days of the request (N.J.A.C. 5:23-2.18). A contractor may not start before the permit is issued (N.J.A.C. 13:45A-16.2).
Work that needs no permit
Ordinary maintenance, like painting, flooring, new cabinets or swapping a fixture without changing the piping, needs no permit (N.J.A.C. 5:23-2.7). The full list is in do you need a permit in NJ.
