Special Transitory Food Units (STFU)
A Special Transitory Food Unit (STFU) is a food service operation that serves a limited menu from an enclosed trailer or other approved layout. Once licensed, an STFU can operate throughout the State of Michigan.
Requirements to Operate a Special Transitory Food Unit (STFU)
Although each operation is unique, there are some basic items that are required for permanent outdoor food service like an STFU. Read more in this helpful document (PDF).
- An STFU must submit a plan review packet, including a plan review application, fee, menu, standard operating procedures, drawing/photos/layout of trailer, equipment specification sheets, and any other applicable items listed below.
- An STFU must have the equipment and resources to ensure food safety for its menu and operation. This typically includes items such as running water to wash hands and equipment/utensils, a method to sanitize equipment surfaces, a metal stem thermometer, methods of hot and cold holding of foods, and a method of covering and protecting food from customers and the elements.
- An STFU must have the unit's name and operator's city on each side of the exterior in letters at least 3 inches high.
