Summary
A food truck operating in unincorporated Williamson County must hold a mobile food unit permit. Under Health and Safety Code Section 437.003 the commissioners court requires county permits for mobile food units outside city limits, with inspection and an approved commissary.
To enforce state law and rules adopted under state law, the commissioners court of a county by order may require food service establishments, retail food stores, mobile food units, and roadside food vendors in unincorporated areas of the county, including areas in the extraterritorial jurisdiction of a municipality, to obtain a permit from the county.
Full Breakdown
Texas Health and Safety Code Section 437.003 lets a county's commissioners court require food establishments and mobile food units in unincorporated areas to obtain a county permit. Williamson County exercises this authority through its health authority, so a food truck serving the unincorporated county must carry a valid mobile food unit permit, pass inspection, and operate from an approved commissary. The permit covers food safety, water, and waste, consistent with the Texas Food Establishment Rules. Trucks working inside Georgetown, Round Rock, Cedar Park, Leander, Hutto, or Taylor also need that city's permit.
Violations & Fines
Operating a mobile food unit without a valid permit allows the health authority to halt operations, impound the unit, and pursue fines; permits are suspended for failed inspections or unsafe food handling.
