Casper is the second largest city in Wyoming and the most economically diverse part of the state outside of Cheyenne. The city sits at the crossroads of I-25 and US-20/26, anchored by Casper College, Wyoming Medical Center, the regional oil and gas industry, and a steady summer event calendar that runs from the Beartrap Summer Festival through the Central Wyoming Fair and Rodeo. Food trucks here split their time between downtown lunch service, brewery patios, oil patch catering, and the events at David Street Station. The market is bigger than most operators expect when they first look at the population numbers, and it’s well-suited to operators who can run high volume from a single location.
Casper-Natrona County Health Department (CNCHD) runs the local health program for both the City of Casper and Natrona County. They’re one of only six local health departments in Wyoming and they handle their own plan reviews, mobile food unit permits, and inspections without going through the state Department of Agriculture. We’re Zion Foodtrucks, based in Woodland Park, Colorado, about a four hour drive from Casper. We’ve built BBQ smoker trailers and stepvan units for Wyoming operators working oil patch catering, ranch events, and the Casper event circuit, and this guide reflects what we’ve learned getting trucks through CNCHD’s environmental health office.
How Casper and Natrona County Food Truck Permits Actually Work
Casper-Natrona County Health Department’s Environmental Health Division at 475 South Spruce Street is the licensing authority. They handle plan review, mobile food unit permitting, and routine inspections. Their main number is (307) 577-9752. CNCHD inspects every mobile unit at least twice a year on an unannounced basis and uses the FDA Food Code framework with Wyoming amendments.
The City of Casper layers a separate health license requirement, with fees described in a published table on the city’s website. The City of Casper also requires the standard business license through the city clerk. Fire safety inspection sits with two possible bodies: Casper Fire-EMS Department for trucks operating inside the city limits, and Natrona County Fire Protection District for trucks operating outside the city. Both reference the 2021 International Fire Code and incorporate NFPA 96 (commercial kitchen ventilation) and NFPA 58 (LP-gas) as the technical baselines.
One thing that catches operators off guard: Casper-Natrona is a strong commissary enforcement jurisdiction. CNCHD verifies commissary letters by phone, and a fake or out-of-date commissary agreement is one of the fastest ways to lose a permit. We recommend operators lock down their commissary before they even start the plan review.
Permits and Licenses Required to Operate a Food Truck in Casper
- Wyoming business entity (LLC or corporation). Filed with the Wyoming Secretary of State at sos.wyo.gov. About $102 to file an LLC online; $60 minimum annual report.
- Wyoming sales/use tax license. Free, applied for through the Wyoming Internet Filing System at excise-wyifs.wy.gov. Casper’s combined sales tax rate is 5 percent (4 percent state, 1 percent Natrona County).
- Casper-Natrona County Health Department Mobile Food Unit Permit. Issued by CNCHD Environmental Health at 475 South Spruce Street. Initial license fees and annual renewals are set by the CNCHD board of health and published in the city’s health license fee table. Plan review is required for any unit that hasn’t operated under a CNCHD permit before.
- City of Casper business license. Required for operating within Casper city limits. Apply through the City Clerk’s office at City Hall, 200 N. David Street.
- City of Casper health license. A separate fee applies for the city’s mirroring of the health permit. The fees are described in a table on the City of Casper’s business licensing page at casperwy.gov/business_detail_T11_R18.php.
- Fire department inspection. Casper Fire-EMS at (307) 235-8222 for in-city operations or Natrona County Fire Protection District at (307) 235-9200 for outside the city.
- Commissary letter. CNCHD requires a written agreement from a permitted commercial kitchen. Phone verification by CNCHD is standard.

Estimated First-Year Casper Food Truck Costs
- Wyoming LLC formation and first annual report: $162
- CNCHD mobile food unit permit (initial): $200 baseline
- CNCHD plan review (typically built into initial permit): $0 to $250 separate fee depending on the year’s fee schedule
- City of Casper business license: $25 to $100 depending on category
- City of Casper health license: per the published fee table
- Casper Fire-EMS inspection: $0 standard inspection
- Sales/use tax license: $0
- ServSafe Food Protection Manager certification: $125
- Food handler cards (3 employees): $30
- Commissary kitchen rental (annual): $1,800 to $4,800
- General liability insurance: $700 to $1,400
- Commercial auto insurance: $1,300 to $2,400
- UL 300 fire suppression semi-annual inspection: $200 to $400

Total first-year compliance costs land in the $5,200 to $11,200 range, not counting the truck. Casper’s commissary market is healthier than Cheyenne’s; there are several shared use kitchens around the East 2nd Street and Yellowstone Highway corridors and several restaurant operators in town who lease off-hours space.
Fire Safety Inspection: What Casper Fire-EMS Looks For
Casper enforces the 2021 International Fire Code with NFPA 96 and NFPA 58 as the technical baselines. Casper Fire-EMS handles inspections for trucks operating inside city limits; Natrona County Fire Protection District handles county areas. Both fire marshals look for the same items.
- Type I hood meeting NFPA 96. Stainless construction, 6 inch overhang on all open sides of the cooking surface, listed grease filters at the prescribed angle, captive air design.
- UL 300 listed wet chemical fire suppression system. Ansul R-102, Pyro-Chem PCL-300, Range Guard, or equivalent. Tagged within six months.
- Manual pull station. Located in the path of egress, clearly labeled, drops both gas and electric to cooking equipment when activated.
- Mechanical gas shutoff valve. Tied to the suppression system, automatic shutoff on system discharge.
- K-Class fire extinguisher. Within 30 feet of the cookline, accessible without crossing the cookline.
- 2A:10B:C extinguisher. Mounted near the primary egress.
- Propane installation. Maximum 200 lb aggregate. Cylinders secured in a vented compartment, NFPA 58 compliant fittings, regulators with overpressure protection, excess flow valves, and a listed LP-gas alarm in the gas system area.
- CO detector. If a generator is mounted on or near the unit.
- Electrical compliance. GFCI on all 120V circuits, no extension cords as permanent wiring, properly rated service.
- Egress. Service window with positive latching and primary entry/exit door.

Built for Wyoming-Style BBQ Operations
This is a 26ft BBQ smoker food trailer we built for a Wyoming barbeque operation. Smoker trailers are huge in Wyoming for a few reasons: oil field and ranch catering jobs run all day with crews that want serious volume, county fairs (Central Wyoming Fair in Casper, the Wyoming State Fair in Douglas, the Sheridan WyoRodeo) need vendors who can throw out 200 plus brisket plates, and ranch wedding catering pays premium money for whole-hog and pit beef setups. We build smoker trailers around offset offset firebox geometry, NFPA 96 compliant grease ducting where required, and water/waste systems sized for 12 hour service days.
Casper-Natrona County Health Department Inspection
CNCHD’s environmental health office uses the standard FDA Food Code framework. The program manager has publicly stated that violations are either fixed immediately during the inspection or within 10 days for items that need parts or service. Items they always check on a mobile unit:
- Handwash sink. Dedicated, hot water at minimum 100°F, soap, and single-use towels. Cannot share with food prep or warewashing.
- Three compartment sink. Compartments large enough for your largest equipment, drainboards on both sides, hot and cold water.
- Fresh and waste water capacity. Wastewater tank at least 15 percent larger than the fresh water tank. Both labeled.
- Refrigeration. All TCS food at 41°F or below, calibrated probe thermometer present and used.
- Hot holding. 135°F or above for time-temperature controlled foods.
- Cooking temperatures. 165°F poultry, 155°F ground meats, 145°F whole muscle and seafood.
- Date marking. Anything refrigerated more than 24 hours marked with discard date no more than 7 days out.
- Commissary log. Documentation of where you fill water, dump grey water, and store/prep food.
- Person in charge demonstration of knowledge. Inspector questions during the visit.
- Pest exclusion. Window screens, no openings around the service window or door seals.
Inspection results in Casper are published weekly through the Oil City News health and food inspection digest. CNCHD’s reports are public record. We’ve seen this transparency work in operators’ favor – good operators get free advertising, and operators with chronic violations have a hard time hiding from regular customers.
The Commissary Kitchen Requirement in Casper
CNCHD requires every mobile food unit to operate from a permitted commissary unless the unit is fully self-contained. The commissary must hold its own current Wyoming food license. Home kitchens are not allowed under any circumstance. CNCHD will phone verify the commissary, often the same day they receive your plan review, and will revoke the permit if your commissary letter doesn’t match the actual operation.
Commissary options in Casper include shared use kitchens (Casper has several established commissaries on East 2nd Street and out by the airport), restaurant kitchens leasing off-hours capacity (the most common arrangement), school kitchens during summer with proper permitting, and church kitchens that hold a CNCHD food license. The key questions to ask any potential commissary: what’s their current CNCHD license number, what hours can you access the kitchen, what utilities are included, where do you fill potable water, where do you dump grey water, and do they have walk-in cooler space if you need overnight storage.
Wyoming State Considerations for Casper Operators
Casper sits in Natrona County, which means CNCHD handles your food licensing – not the Wyoming Department of Agriculture. But several state level pieces still apply. Wyoming Department of Revenue handles your sales tax. Wyoming Secretary of State handles your business entity. Wyoming State Fire Marshal sets the fire code adoption (currently the 2021 IFC) that Casper Fire-EMS enforces locally.
Wyoming’s no state income tax structure is particularly meaningful for Casper operators with high catering volume. The oil field catering business in central Wyoming – feeding crews at well sites, drilling rigs, and field offices – runs on contract revenue that can scale into the six figures for a single operator within 18 months of opening. Without state income tax, the difference between operating in Casper versus operating in Denver on similar revenue is roughly 4 to 5 percent of net income retained.
Casper’s combined sales tax rate is 5 percent. Prepared food is fully taxable. Wyoming sources sales tax to the location of delivery, so a Casper truck doing a wedding catering at a ranch in Converse County collects Converse County’s tax rate (which is also 5 percent) on those sales. Most central Wyoming counties run at the 5 percent rate.
Step-by-Step: How to Get Your Casper Food Truck Licensed
- Form your Wyoming LLC. Online filing at sos.wyo.gov, about $102. Get an EIN from the IRS.
- Register for sales tax. Wyoming Internet Filing System at excise-wyifs.wy.gov. No fee.
- Call Casper-Natrona County Health Department Environmental Health. (307) 577-9752. Ask for the mobile food unit plan review packet.
- Lock down your commissary. Get a signed letter on the commissary’s letterhead with their CNCHD license number. CNCHD will phone verify.
- Submit the plan review. Floor plan, equipment list with NSF certifications, water and waste tank capacities, electrical and plumbing schematics, finish schedule, menu, food flow narrative, and the commissary letter.
- Build or buy your truck to spec. Working with us at Zion means the plan review packet ships with the unit, sized to clear CNCHD on first review.
- Schedule the fire department inspection. Casper Fire-EMS at (307) 235-8222 for in-city operations.
- Schedule the CNCHD final inspection. After fire approval. Truck must be at the inspection location with water filled, propane connected, and operator on hand.
- Pay CNCHD permit fees. Per the current CNCHD fee schedule.
- Apply for the City of Casper business license and city health license. Through the city clerk at City Hall, 200 N. David Street.
- Display your licenses. All permits, suppression tag, and propane inspection certificate visible inside the truck during operations.
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.
Casper-Specific Operating Context: Where to Park, When to Be There
Casper’s market has more variety than the population suggests. Operators who succeed here typically run three or four anchor accounts and a steady event calendar.
- David Street Station. The downtown public plaza at 200 South David Street hosts food truck rotations, concerts, and community events through the warm months. Permitted vendors get a steady lunch and dinner crowd.
- Beartrap Summer Festival. The Casper Mountain bluegrass and acoustic music festival in early August. Vendor space is booked through the festival; demand for food along the way up Casper Mountain Road is heavy.
- Central Wyoming Fair and Rodeo. Mid-July at the Central Wyoming Fairgrounds. One of the largest fairs in the state.
- Casper College. Casper College and Wyoming Catholic College combined enrollment provides a steady younger market. Casper College’s main campus on College Drive runs lunch traffic.
- NIC Casper. The Natrona County Library and the Wyoming Medical Center campus are downtown lunch anchors.
- Oil patch catering. Crew catering at well sites, drilling rigs, and field offices in the Salt Creek, Frontier, and Hilight areas. These contracts often pay $10 to $15 per plate for 30 to 80 person crews. Logistics are demanding (long drives, generator power, cold weather).
- Brewery patios. Backwards Distilling, Frontier Brewing, and others run food truck nights through the season.
- Casper Music Series at Washington Park. Weekly summer concerts.
- NCAA wrestling and rodeo events at Ford Wyoming Center. The arena’s event calendar drives downtown food truck demand.
Casper Food Truck FAQ
Can I cater at a well site or drilling rig with my Casper truck?
Yes, with a few caveats. Your CNCHD mobile food unit permit is valid statewide for Wyoming-CHS jurisdiction operations as long as you maintain your home base in Natrona County and your commissary stays current. For sites outside Natrona County, you’ll need to confirm with the local jurisdiction whether they require a temporary event permit or recognize your CNCHD license. Most central Wyoming sites are in CHS jurisdiction (state level) and will recognize a current Wyoming license without requiring a separate permit.
What’s the rule on propane on a smoker trailer?
For a wood or charcoal fired smoker that doesn’t use propane for primary cooking, you still need to comply with NFPA 58 for any propane on the unit (typically used for ignition or auxiliary cooking). The 200 lb aggregate cap applies. The hood and Ansul requirements depend on what’s under the hood – if you have a flat top or fryer alongside the smoker, the hood and suppression must cover those. If the smoker is the only cooking equipment and it vents externally through a stack, that’s typically treated separately under solid fuel cooking provisions of the IFC.
How does Casper winter operation work?
Casper winters are real winters. January and February average highs are in the low 30s and overnight lows can drop to negative 10°F or worse. Trucks operating year round need heated water bays, heat traced exterior plumbing, and propane heat in the customer area. Hot holding equipment works harder; cold holding works easier. Most Casper operators run a 9 to 10 month season, with December as the soft floor and steady ramp from March on. Indoor event catering keeps trucks busy through the winter.
Do I need a separate permit to operate at the Central Wyoming Fairgrounds?
The CNCHD mobile food unit permit covers food safety. The fairgrounds itself often books vendors through their concessions process for the fair and rodeo, with vendor space fees and electric/water hookup fees on top. Smaller events at the fairgrounds outside of fair week typically work direct with the event organizer.
Can I commissary out of a restaurant kitchen if I’m a part-time tenant?
Yes, as long as the restaurant has a current CNCHD food license and provides a written letter on letterhead documenting your access. Most Casper operators do this. The restaurant must have a separate handwash and sanitization protocol if you’re prepping during their operating hours, but if you’re prepping off-hours, you’re working in their licensed space and your own license covers the rest.
Is there a separate permit for selling at the Casper Farmers Market?
The Casper Farmers Market at David Street Station and the Casper College Farmers Market book vendors through the market manager. Mobile food units with a current CNCHD permit are eligible. Cottage food operators (selling under Wyoming’s Food Freedom Act) participate under separate rules and don’t need a CNCHD permit, but a food truck always does.
What if my truck breaks an inspection rule mid-day?
CNCHD’s stated practice is that violations are either fixed immediately or addressed within 10 days. Critical violations (cold holding failure, suppression system off-tag, raw sewage discharge) can result in immediate cease-of-operations until corrected. Non-critical violations get a re-inspection date and corrective action notice. Either way, the inspector documents and you sign the report. Don’t argue at the truck. Fix the issue and get back online.

How Zion Foodtrucks Helps Casper Operators
We’re based in Woodland Park, Colorado, about a four hour drive from Casper. We’ve built smoker trailers, stepvan units, and concession trailers for Wyoming operators running oil field catering, ranch events, and the Casper event circuit. Every Casper truck we deliver ships with documentation a CNCHD environmental health inspector or a Casper Fire-EMS marshal will ask for: NSF certifications on food contact equipment, UL 300 listed wet chemical suppression with installation paperwork, NFPA 58 compliant propane installation with the inspection certificate, and an as-built schematic that drops cleanly into the CNCHD plan review packet. We size cold holding for Wyoming summer heat, fresh and waste water for full day catering capacity, and propane for cold morning starts.
If you’re starting a Casper truck or replacing an aging one, call us at (719) 722-2537 or email info@milehighfoodtrucks.com. We’ll put together a build quote, a CNCHD-ready plan review packet, and a delivery timeline in one call. We deliver to Casper directly and can set up service runs north when warranty work is needed.
