What does a food truck need in Knox County Tn that other businesses do not?
1 of the 3 permits particular to a food truck here applies to no other business type we cover in Knox County Tn: Mobile Food Unit / Mobile Cart Health Permit (KCHD).
Mobile Food Unit / Mobile Cart Health Permit (KCHD)
The $210 figure is KCHD's own published fee: the Knox County Health Department's fee table on its Environmental Health FAQ page lists 'Mobile Food Unit' at $210 for the July 1 – June 30 permit year, and its Mobile Cart Plan Review Guidance (revised 10 November 2025) states 'The permit fee is $210.00 per year (July 1 to June 30).' KCHD's Mobile Food Unit Guidance states that the state food service rules require plans drawn to scale for mobile food units to be submitted to the local health department for review and approval before construction or modification. The cart guidance requires operating from an approved commissary, and the FAQ says a commissary agreement must be on file with the local health department when a commissary is used. Inside the City of Knoxville, the city's own mobile food unit permit is a separate requirement on the Knoxville page. Contact KCHD at (865) 215-5200 or environmental.plans@knoxcounty.org.
