Food Cart Rules and Regulations in Utah
Food carts and trucks are regulated by a number of state and local laws and regulations. Before starting a food cart or truck business, consult your local health department, read the regulations that apply to you and apply for the appropriate permits.
Located in the Salt Lake area? The Salt Lake Valley Health Department has information and applications for food carts, mobile units and shaved ice stands here. As the Health Department notes, you should also contact your city to determine what other regulations you'll need to follow.
Of course, you'll find food carts (and maybe even food trucks) outside of the Salt Lake area. For example, the Southwest Utah Public Health Department has a list of mobile food service regulations on their website.
