Inspection Frequency: Restaurant inspections are normally scheduled for one to four inspections per year, depending on the complexity of the menu, how much food is made from raw products, and how much is made in advance rather than cooked-to-order. (For example: restaurants that handle food more frequently are inspected more frequently than a restaurant that serves food such as a sandwich made to order.) Inspectors from the Health District regularly conduct unannounced inspections of food service establishments. Inspections listed on this site include all regular, follow-up or complaint investigation inspections.
