Casper is the center of Wyoming’s oil country and one of the better food truck towns in the state, with the College National Finals Rodeo, the events center and a loyal lunch crowd. This guide was rewritten in October 2026 from the county health department’s own forms.
Plan review, handled. Before Casper Natrona County Health licenses a truck, it wants a plan review: the layout, the equipment list, and the water and wastewater plumbing. We provide the build documentation, plumbing schematics and equipment specs your health department asks for, and we build to pass the inspection the first time. Most of our Wyoming trucks are built at our Denver shop, Mile High Food Trucks; see their Casper food truck builder page and the Wyoming permits guide. Call or text 719-722-2537.

The health license
The state food license under W.S. 35-7-124 is $200 new and $100 a year to renew, runs one year from the date it is issued, and comes from either the Wyoming Department of Agriculture or a local health department. You need one license, not two.
In Natrona County you apply through the Casper Natrona County Health Department, but the fee is paid to the Wyoming Department of Agriculture, which issues the license and mails renewals. Plan review for a mobile unit is $125. The county requires the commissary to be named on the application, pressurized water rather than gravity, and waste tanks 15 percent larger than fresh water.
Natrona County adopted a local rule in 2023 that makes a certified food protection manager mandatory, which the state does not require. And a commissary dependent unit licensed here may not operate outside Natrona County, so if you want to work Cheyenne or Gillette, build the truck self sufficient.
The Casper city permit
Casper does not require a separate city health or business license for mobile units. It does require a city fire inspection, and it issues vendor permits for public spaces; in 2026 the city council discussed replacing the per parking space fee with a flat $25 permit, so check the current rule with the city before you plan a downtown spot.
Fire inspection
The Casper Fire Department inspects trucks before they operate in the city. Inspectors look for a Type I hood with a UL 300 suppression system serviced every six months, Class K and ABC extinguishers, propane cylinders secured outside the cab with leak tested lines, and a propane alarm.
Sales tax
Natrona County’s combined rate is 5 percent, 4 percent state plus 1 percent county; confirm on the Department of Revenue’s current chart.
Where trucks sell in Casper
The College National Finals Rodeo in June, Ford Wyoming Center events, the downtown David Street Station events, oil field crews at lunch, breweries and private catering.
In order
Line up a commissary in Natrona County or build the truck self sufficient. Submit the $125 plan review, get a certified food protection manager, pass the inspection and pay the state license fee. Pass the Casper Fire inspection, then register for sales tax.
Common Reasons Food Trucks Fail Casper Inspections
- Commissary doesn’t pass phone verification. CNCHD calls. If the commissary doesn’t recognize the operator, the application stops there.
- Wastewater tank undersized. 15 percent rule applies. CNCHD inspectors measure.
- Cold holding equipment can’t make 41°F under load. Inspectors will probe coolers full of food on a hot day. Undersized refrigeration is a fast fail.
- Suppression tag past six months. Get on a calendar with a Wyoming-licensed fire suppression contractor.
- Date marking missing on prepped product. Prep done the day before with no date sticker is an automatic citation.
- Person in charge can’t answer questions. The inspector will ask about reportable illnesses (the Big Five), allergens, and TCS food handling. Have your operator ready.
- Propane lines unprotected at chassis crossings. NFPA 58 requires protective sleeves and securing at intervals.
- K-Class extinguisher missing. The general purpose extinguisher does not substitute. Both are required.
- No food handler cards visible. Have them on the truck, not in your phone, not at home.
Frequently asked questions
How much is a food truck license in Casper?
The state food license is $200 new and $100 to renew, paid to the Wyoming Department of Agriculture after you apply through Casper Natrona County Health. Plan review for a mobile unit is $125.
Do I need a certified food manager in Casper?
Yes. Natrona County adopted a local rule in 2023 requiring one, even though the state does not.
Can a Casper licensed food truck work in other counties?
Not if it is commissary dependent; the county’s form says those units will not be allowed to operate outside Natrona County. A self sufficient truck avoids that limit, but call each county before you go.

Building a truck for Casper
We build every truck to pass the plan review, the health inspection and the fire inspection on the first visit: a Type I hood with suppression installed by a licensed company, a three compartment sink and a hand sink with hot water, tanks sized for a full day, and propane in secured cylinders with a leak detector. Wyoming winters are hard on trucks, so we heat and insulate water lines and tanks on every Wyoming build. We built a sourdough donut trailer for Casper. Custom food trucks start at $55,000 and trailers at $40,000. Call or text 719-722-2537 with your menu.

Already Have a Truck? We Do the Compliance Work Too
Passing an inspection is one thing, staying current is another. We handle the recurring items out of our Colorado shop:
- LP gas pressure testing, $350. Required annually, and again after any modification.
- Fire suppression inspection and service, $300. The code interval is every 6 months, not annual, which catches a lot of operators out.
- Hood and exhaust cleaning, with the written report and logbook entry inspectors ask to see.
Booked together they are one visit and one day off the road instead of three. Call or text 719-722-2537.
