Under UPC, food establishments here must control fats, oils & grease (FOG) with a grease interceptor or trap, and typically register with the local sewer/wastewater authority. A grease interceptor sized to the California Plumbing Code is required, with a municipal sewer-authority FOG discharge permit.
Size the interceptor with our grease-trap sizing calculator, compare units in the grease-trap catalog, and confirm the local FOG permit with Sonoma County Environmental Health & Safety (Dept. of Health Services) (contact above).
Hood fire suppression (IFC): commercial cooking under a Type I hood needs a wet-chemical suppression system to NFPA 96, permitted and inspected by the local fire marshal. Type I hood fire suppression must meet NFPA 96 and the California Fire Code enforced by the local fire authority. See do I need a hood? and the hood CFM calculator.
Backflow prevention: An approved backflow preventer with a certified annual test is required by the local water purveyor. A certified backflow assembly (often an RPZ) on the water service, tested annually, is standard — confirm with your water utility.
