Under NSPC 2021 (NJ UCC Plumbing Subcode), food establishments here must control fats, oils & grease (FOG) with a grease interceptor or trap, and typically register with the local sewer/wastewater authority. Grease interceptors are required where grease-laden waste is produced, sized under the state plumbing subcode, with the FOG discharge permit issued by the local sewer authority.
Size the interceptor with our grease-trap sizing calculator, compare units in the grease-trap catalog, and confirm the local FOG permit with Middlesex County Office of Health Services (Department of Public Safety & Health), Inspection Division (NJ-licensed Registered Environmental Health Specialists inspect food establishments under Chapter 24); retail food LICENSES are issued by each municipality (contact above).
Hood fire suppression (IFC 2021): commercial cooking under a Type I hood needs a wet-chemical suppression system to NFPA 96, permitted and inspected by the local fire marshal. Commercial kitchen hood suppression follows NFPA 96 and is permitted and inspected by the local fire official under the NJ Uniform Fire Code. See do I need a hood? and the hood CFM calculator.
Backflow prevention: An annual RPZ/backflow assembly test is required under state cross-connection control rules and administered by the public water supplier. A certified backflow assembly (often an RPZ) on the water service, tested annually, is standard — confirm with your water utility.
Health-department plan review looks for specific, code-compliant fixtures. Compare spec-filtered options, then confirm counts and sizes with your local requirements. See the full list in what equipment a commercial kitchen requires.
