What permits do you need to open a food truck in Williamson County?

There is no single figure, and any site quoting one is rounding away the part that matters. Of the 6 records listed for a food truck in Williamson County, TX, 2 apply to every business of this type and 4 are conditional. Adding every fee on the page together would overstate what most operators pay, because it would include permits they never need.

Of the 2 that always apply, 1 carry a flat fee, coming to $0.00. That is a floor, not a total. 2 of the 6 are charged as a range or a formula set by the issuing agency, and 0 have no fee published at all. The ones that vary:

Temporary Food Establishment Permit: $52–$200 two weeks or a calendar year

Mobile Food Vendor Permit (State): $309–$876 application fee, by food-handling type

Permits for a food truck in Williamson County, TX come from 4 separate offices: Williamson County and Cities Health District, Texas Secretary of State, Texas Department of State Health Services, Texas Comptroller of Public Accounts. No single office issues them all, which is why an opening means filing in several places rather than one.

$52 covers issuance and inspection for two weeks. A multiple temporary permit at $200 covers the entire calendar year, so it pays for itself at four events. Both carry the same $100 late fee. If you work more than three events a year in Williamson County, the annual option is the obvious choice.

$100 a year with no late fee — the only permit on this schedule that carries none. The district quotes the statute it is bound by: under section 437.0065(c) the permit must run at least a year, may not exceed $100 to issue or renew, and must cover sales at all farmers' markets, farm stands and farms inside the jurisdiction. So $100 buys access to every market in the county, not one.

Required to form an LLC or corporation, not to trade as a sole proprietor. Texas has no statewide general business licence, so for many businesses this filing plus a sales and use tax permit is the entire state-level obligation.

Only needed if you trade under a name different from the one on your formation filing. The certificate is effective for a term not exceeding ten years from the date of filing and does not roll over by itself — it must be actively renewed, and a new certificate can be filed within six months of the original expiring. The $25 is the Secretary of State fee; sole proprietors and general partnerships file with the county clerk instead, at county rates.

Since 1 July 2026 one DSHS permit covers every Texas jurisdiction, replacing separate permits from each local health department. Three tiers by food handling: Type I (no time/temperature controlled foods) $309 with no pre-licensing inspection fee; Type II (limited TCS handling) $618 plus a $400 pre-licensing inspection; Type III (full preparation) $876 plus a $500 pre-licensing inspection. The licence expires one year from the successfully completed pre-licensing inspection, not from the application date. Temporary food dealer permits could not be issued to mobile vendors in Texas after 30 June 2026.

There is no fee for this permit — the Comptroller says so directly, which is worth stating because a blank fee reads as though nobody knows. It does not expire on a date, but it is not permanent either: it is valid only while you are actively engaged in business as a seller, and the Comptroller's office may cancel it on finding that you are not. Filing obligations keep it alive, so a return must be filed for every period even when there were no taxable sales or purchases to report. Apply through Comptroller eSystems and allow two to three weeks.
