O'Fallon food truck FAQs
How much does it cost to start a food truck in O'Fallon?
Most owners spend $30,000–$100,000 on a used truck or trailer and equipment (new builds run higher), plus permits and licensing. Permit and license costs vary enormously by city — from a few hundred dollars a year in smaller towns to five figures in the biggest markets — so confirm current O'Fallon fees with the local health department before you budget.
Do I need a O'Fallon-specific permit if I'm already licensed elsewhere in Missouri?
Usually yes. O'Fallon runs its own mobile vending program, so plan on a local vending permit and inspection even if you're already permitted in another Missouri city.
How do customers in O'Fallon find a truck that moves around?
