St. Louis County, MO Food Trucks & Mobile Vendors: Food Truck Permits (2026)

110 requires the owner or person in charge of a mobile food establishment to pay the required fee, obtain a permit from the Director annually, and present the unit for inspection as the Director requires. Subsection A lets the Director impose extra health-hazard rules on mobile operations, prohibit sale of potentially hazardous food, or waive some physical-facility requirements, but never waives the requirements for water systems, waste retention, servicing areas or commissary operation. Subsection B requires every mobile food establishment to display a valid, approved sticker or permit at all times in a place conspicuous to the public.

Subsection C requires the owner's or business's name, address and phone number, legible and permanently marked on at least two exterior sides, with the name in letters at least 3 inches high and address/phone at least 1 inch high, in a color contrasting with the exterior. Subsection D requires the operator to submit approved commissary documentation and, on request, a current list of planned food-service locations and arrival times. Item 16 requires every unit to operate from an approved commissary or fixed food facility and report there daily for food, supplies, cleaning and waste disposal; if the commissary sits outside St.

Louis County, the operator must prove it holds a valid license and passed a recent inspection where it's located. 030 separately classify a "temporary food establishment" as one operating no more than 14 consecutive days per permit year at the same location for the same permittee, and a "seasonal food establishment" as one running 15 to 120 days per permit year.
