Under Illinois Plumbing Code (77 Ill. Adm. Code 890, IDPH), 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 under the Illinois Plumbing Code, with FOG limits enforced by the local sewer district.
Size the interceptor with our grease-trap sizing calculator, compare units in the grease-trap catalog, and confirm the local FOG permit with Lake County Health Department & Community Health Center (Population/Environmental Health Services) (contact above).
Hood fire suppression (NFPA 101 Life Safety Code (2015 ed.)): 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, with the Illinois State Fire Marshal enforcing the Life Safety Code statewide and local fire departments inspecting. See do I need a hood? and the hood CFM calculator.
Backflow prevention: Restaurants must install a testable backflow preventer (typically an RPZ) that is tested annually and reported to the local water utility. A certified backflow assembly (often an RPZ) on the water service, tested annually, is standard — confirm with your water utility.
