What does a restaurant need in Mercer County Nj that other businesses do not?
Retail Food Establishment License
Chapter 24 of title 8 of the New Jersey Administrative Code, as published by the Department of Health, sets no state retail food license and no state fee — its only fees are the $100.00 cottage food operator permit and its $100.00 renewal (8:24-11.6). Licensing sits with more than a hundred local boards of health, and they band differently: Hamilton by risk type from $175 to $300, Randolph by risk type from $80 to $500 with a floor-area surcharge of a quarter over ten thousand square feet and double over forty thousand, Hanover by floor area alone from $250 to $1,000. The state department licenses only a narrow slice directly — turnpike and parkway rest stops, facilities on state property, cottage food and frozen desserts. There is no statewide fee table and it would be wrong to publish one.
Certified Food Protection Manager
No state fee — the Department of Health says it offers no food protection manager courses or programmes, and an accredited certifier charges what it charges. The state rule requires it only at Risk Type 3 establishments, which covers full-service restaurants, diners, commissaries and caterers; risk types 1 and 2 need only a knowledgeable person in charge. Many local health departments extend it to risk type 4 as a license condition, so check the town as well as the state. The manager need not be on the premises at all times but a person in charge must be. New Jersey requires no food handler card — the phrase does not appear in the retail food code — though individual municipalities do impose one.
The other 2 local permits in the tables apply to every type of business in Mercer County Nj, NJ; what each one involves is set out on the Mercer County Nj permits page. The 5 state-level registrations apply to every type of business across NJ and are covered on the NJ state page.
