Duncan food truck FAQs

How much does it cost to start a food truck in Duncan?

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 Duncan fees with the local health department before you budget.

Do I need a Duncan-specific permit if I'm already licensed elsewhere in Oklahoma?
