To buy a coffee truck in Wisconsin, start by defining your build and compliance plan, then shop inventory that meets ATCP 75 (Wisconsin Food Code). Prioritize a layout with a 3-compartment sink, hand sink, hot water at 110°F, NSF equipment, fresh/grey tanks (grey at least 15% larger), 30A–50A electrical with a 7–10 kW generator, and a 220V/30A circuit for a 2‑group espresso machine. Budget: used coffee trucks $45k–$110k, new builds $120k–$200k; coffee trailers $25k–$80k. Secure a Mobile Retail Food Establishment license through DATCP or your local agent health department (e.g., Milwaukee, Madison–Dane), a Wisconsin seller’s permit (DOR), title/registration, and commercial auto plus $1M/$2M general liability and inland marine coverage; a CFPM is typically required. Plan for Wisconsin winters: enclose plumbing, insulate lines, add heat tape and tank pad heaters, keep water tanks inboard, and avoid antifreeze in potable systems; verify propane ventilation and carry a K‑class extinguisher. Most jurisdictions require a commissary/service base for water fill, waste disposal, and daily cleaning. Test throughput: dual windows, 2 grinders, and a 3‑boiler machine support 150–300 drinks/day at $5 average. For routes and event permits, check Milwaukee and Madison street vending rules; add 30A shore power and a cellular router for POS uptime.
