What does a restaurant need in Naperville that other businesses do not?
Retail Food Establishment Permit
The Department of Public Health's Retail Food page states that retail food establishments in Illinois, 'including restaurants, bakeries, grocery stores, and food trucks, are regulated by local health departments serving the jurisdiction where the establishment is located', and directs anyone starting a retail food business to the local health department, so the permit and its fee are set locally and depend on the county or city. The state reserves permitting to itself only for food processing plants, which it splits with the Department of Agriculture. The code itself is the 2022 FDA Food Code as adopted by Illinois, and inspection findings are graded as priority, priority foundation or core rather than by a numeric score.
