Food trucks in Wisconsin
In Wisconsin, the Department of Agriculture, Trade and Consumer Protection (DATCP) licenses mobile food establishments, and agent local health departments license and inspect on its behalf in some areas. A mobile unit needs two licenses: one for the unit and one for its service base. Mobile licenses are transferable between counties, but local jurisdictions can still inspect your unit and charge an inspection fee.

Questions and answers
Does a Wisconsin mobile food license work in every county?
DATCP says mobile licenses are transferable, so a unit licensed in one county can operate in another without additional licensing. Local jurisdictions can still inspect your unit and charge an inspection fee, and some cities add their own permits, such as Milwaukee's Mobile Sellers Permit.
What is a service base in Wisconsin?
It is the licensed place that supports the mobile unit's operations, with water filling, wastewater disposal and cleaning facilities. Every mobile food establishment needs a service base license in addition to its unit license, and must return to the base at least every 24 hours unless at a special event with services available.
Does a Wisconsin food truck need a certified food manager?
Yes. DATCP's fact sheet says mobile food establishments must have a Certified Food Protection Manager. They must also arrange for use of a toilet facility during all hours of operation.
How large do water tanks need to be on a Wisconsin food truck?
DATCP lists 5 gallons for pushcart handwashing, 10 gallons for units that need handwashing and only serve beverages or prepared or reheated foods, and 40 gallons for units that need handwashing, food preparation or utensil washing. The wastewater tank must be at least 15% larger than the water tank.
