Illinois: Restaurant Regulations
Baseline checklist for common requirements. Verify locally (rules vary by AHJ).
Quick takeaway: Most restaurant compliance falls into five buckets: health permits, fire/hood, plumbing/grease, building/occupancy, and zoning. Local authorities can add requirements beyond state minimums.
Typical checklist
| Area | What to verify |
|---|---|
| Health | Food establishment permit, plan review (if required), Person-in-Charge/food safety certification, inspection schedule. |
| Fire | Type I hood (as applicable), fire suppression system (e.g., wet chemical), extinguisher class requirements, fire inspection and permits. |
| Plumbing | Grease interceptor/trap sizing and location, floor drains/mop sink, backflow prevention, wastewater/sewer authority requirements. |
| Building | Certificate of occupancy, change of use, occupant load, ADA accessibility basics, restroom counts. |
| Zoning | Permitted use for the address, parking, signage permits, outdoor seating rules, noise/vent termination limits. |
