Mobile food unit permit requirements come from your local or state health department, which builds its rules on the FDA Food Code and layers on business licensing, fire safety, food handler certification, and insurance before you can serve a single customer. The exact paperwork, equipment standards, and fees depend on how your menu is classified for risk, so the first thing to pin down is which class your operation falls into. Everything else — the build-out, the inspection, the cost — follows from that.
Your Risk Classification Drives Everything
Most health departments sort mobile food units into tiers, commonly Class I through Class IV, though names and numbers vary. The tier is set by what you sell and how much you handle it.
- Class I covers the lowest risk: commercially prepackaged, shelf-stable items like bottled water, chips, or sealed candy. Nothing opened, nothing heated.
- Class II covers unpackaged foods that don’t need temperature control, or prepackaged items that do. Think prepackaged frozen treats or reheating pre-cooked hot dogs.
- Class III covers moderate-risk preparation from individual ingredients without cooking raw animal proteins: sandwiches, salads, ice cream scooping.
- Class IV covers full-service mobile kitchens cooking raw meat, poultry, or seafood. The expectations match a brick-and-mortar restaurant.
Your class dictates the equipment you install, the documents you submit, how often inspectors show up, and what you pay. Permit fees for the simplest operations start as low as $40 in some areas; a complex Class IV kitchen can run $700 or more. Moving up a class is not a paperwork change. It usually means retrofitting equipment and passing a new inspection.
Build Standards for the Unit
The physical build has to match the sanitation demands of your class. Every surface that contacts food or sits near food preparation must be smooth, durable, corrosion-resistant, nonabsorbent, and easy to clean. Stainless steel is the industry standard. Some operators use fiberglass-reinforced plastic for walls and ceilings. Rough wood, unsealed plywood, or anything that can harbor bacteria in cracks or pores will be rejected.
Water and Wastewater
The FDA Food Code requires potable water in enclosed tanks made from safe, corrosion-resistant materials with smooth, easily cleanable interiors. Tank inlets must be three-quarters of an inch or smaller and fitted with a hose connection that prevents cross-use with non-potable systems.1U.S. Food and Drug Administration. FDA Food Code 2022 Full Document Jurisdictions commonly require at least five gallons for basic handwashing, and more for units with dishwashing sinks.
Your wastewater holding tank must be at least 15 percent larger than your freshwater tank, sloped to a drain with a shut-off valve.1U.S. Food and Drug Administration. FDA Food Code 2022 Full Document Busy services generate wastewater faster than operators expect, so building past the 15 percent minimum is worth it.
Temperature and Handwashing
Cold-holding equipment must keep food at or below 41°F. The FDA Food Code identifies 41°F to 135°F as the temperature danger zone where bacteria multiply fastest.2U.S. Food and Drug Administration. Cooling Cooked Time/Temperature Control for Safety Foods and the FDA Food Code Residential mini-fridges will not hold temperature inside a hot truck and will fail inspection. Commercial-grade refrigeration is essential.
Handwashing sinks must deliver running water at a minimum of 85°F and stay physically separate from any sink used for dishes or equipment.1U.S. Food and Drug Administration. FDA Food Code 2022 Full Document Combining the two is one of the most common violations inspectors cite.
Commissary
Most jurisdictions require you to operate from a commissary or licensed servicing area. Whether one is required depends on your menu, your operation type, and the equipment you carry. The commissary gives you a fixed place to dump wastewater, refill potable water, dispose of grease, restock, and perform deep cleaning that isn’t practical inside a truck. A signed commissary agreement from the facility owner is part of your permit application, and some departments require daily return visits. Hourly rental rates typically run $15 to $50.
Fire Suppression and Propane
Any unit with cooking equipment that produces grease-laden vapors needs a fire suppression system. NFPA 96 governs ventilation and fire protection for commercial cooking and applies to food trucks the same way it applies to restaurants. Cooking appliances may only operate when exhaust systems are running, and grease has to be cleaned from hoods and ducts on a regular schedule. Portable fire extinguishers selected and installed per NFPA 10 are required in every cooking area.
Units must maintain a clearance of at least 10 feet from buildings, other vehicles, and combustible materials during operation. The local fire authority can set greater distances based on site conditions. Solid-fuel cooking with charcoal or wood brings additional requirements: those appliances must be protected by listed fire-extinguishing equipment rated for solid fuel.
NFPA 58 governs propane. Tanks must be mounted outside the vehicle or inside a vented cabinet that is vaportight to the interior, with vents near both the top and bottom and at least three feet horizontally from any vehicle opening. The cabinet must be labeled “LP-Gas only” in letters at least one inch high. Capacity limits depend on total appliance input. All piping must be pressure tested after installation or modification at 1.5 times maximum operating pressure for at least 10 minutes, and the entire system needs annual leak testing with results documented and kept onboard.
Certified Food Protection Manager
The FDA Food Code requires medium- and high-risk food establishments to have a certified food protection manager present during all hours of operation. That manager must pass an exam through an ANSI-accredited certification program.3U.S. Food and Drug Administration. Food Code 2022 Recognized programs include ServSafe, the National Registry of Food Safety Professionals, StateFoodSafety, Prometric, and 360Training.
You cannot get your operating permit without the certification. If you are running a Class III or IV unit, schedule the exam early, ideally before the build-out starts. Lower-risk operations handling only prepackaged foods may be exempt from the certified manager requirement, though basic food handler training is still expected in most jurisdictions.
What Goes in the Application
Health department applications require detailed technical documentation. Incomplete packages are the single most common reason for delays, and many departments reject applications outright instead of asking for missing pieces.
Floor Plan
You need a scaled floor plan — most jurisdictions require at least one-quarter inch per foot — showing top and side views. The plan must identify every piece of equipment: cooking surfaces, sinks, refrigeration, dry storage, chemical storage, and ventilation hoods. Label the finish on every wall, floor, and ceiling so the reviewer can confirm materials meet non-porous requirements.
Menu and Flow of Food
The application must include a complete menu listing every item you plan to sell. The menu sets your risk classification and drives the entire plan review. A unit listing raw chicken is reviewed under different standards than one selling only grilled cheese.
Higher-risk operations also need a written narrative describing how food moves through the unit: receiving, storing, thawing, preparing, cooking, cooling, reheating, and serving. The flow-of-food document shows inspectors you have thought through every point where contamination or temperature abuse could happen.
Equipment, Commissary, and Specialized Processing
Equipment specification sheets, sometimes called cut sheets, must accompany the application for every appliance. Reviewers confirm each piece carries certification from an ANSI-accredited program such as NSF International. Serial numbers on your equipment should match the documentation exactly; mismatches flag the file for extra scrutiny. A signed commissary agreement proves you have a legal base of operations.
If your operation involves smoking, curing, fermenting, vacuum-sealing, or using food additives as a preservation method, you will likely need a formal Hazard Analysis Critical Control Point plan identifying hazards, control points, limits, and monitoring procedures.4U.S. Food and Drug Administration. Hazard Analysis Critical Control Point (HACCP) Principles and Application Guidelines Some of those methods also require a formal variance, which is written permission from the health authority to deviate from standard Food Code requirements. Variance applications add weeks to the timeline.
Business Registration and Taxes
A health permit authorizes food preparation. It does not make you a legal business. You also need a general business license from your city or county, and in most cases a state-level seller’s permit or sales tax registration to collect and remit tax. Trucks that move between jurisdictions have to collect the correct tax rate at each location, not just at the home base.
If you hire employees, operate as a partnership or corporation, or owe excise taxes, you need an Employer Identification Number from the IRS. The application is free and takes minutes through the IRS online portal.5Internal Revenue Service. Apply for an Employer Identification Number (EIN) If you are forming an LLC or corporation, register the entity with your state before applying, because the IRS requires the legal entity to exist first. The IRS never charges for an EIN; third-party sites that do are not official.
Insurance You’ll Need
Most commissaries, event organizers, and municipalities require proof of commercial insurance before you can operate. Expect at minimum:
- General liability insurance, covering bodily injury and property damage claims from customers or bystanders. Many venues require at least $1 million in coverage.
- Commercial auto insurance. Personal auto policies exclude business use, so a food truck needs a commercial policy covering collision, comprehensive, and liability. A personal policy will not pay for an accident during operation.
- Workers’ compensation, required in most states once you have employees.
Beyond the basics, food spoilage and contamination coverage protects inventory if refrigeration fails overnight, and equipment breakdown coverage handles unexpected appliance failures. An umbrella policy extends liability limits when a claim exceeds base coverage, which matters in an industry where one foodborne illness incident can generate claims well beyond standard limits.
Plan Review, Pre-Operational Inspection, and the Decal
Once the application package is complete, you submit it through the health department’s portal or office with the required fees. Application fees run from around $200 for simple operations to over $1,000 for complex mobile kitchens. A plan reviewer checks your floor plans, menu, equipment specs, and commissary agreement against the applicable code. Plan review commonly takes two to four weeks.
After plan approval, the unit goes through a pre-operational inspection. The inspector walks through the truck and verifies that what you built matches what you submitted. They check water temperatures, refrigeration readings, fire suppression functionality, handwashing setup, and every food-contact surface. Discrepancies between your plans and the actual build will fail the inspection.
Passing earns you an operating permit and a visible license decal that must be displayed on the unit at all times. Failing means a re-inspection, which carries its own fee, commonly $100 to $150 per visit. The most frequent failure points are water temperature issues, missing or improperly installed equipment, and mismatches between the plans and the truck.
Keeping the Permit After You Open
The FDA Food Code recommends health departments inspect food establishments at least every six months, with frequency adjusted by risk.1U.S. Food and Drug Administration. FDA Food Code 2022 Full Document Low-risk operations selling only prepackaged, non-temperature-controlled foods may be inspected less often. Higher-risk units should expect unannounced visits during service.
You also need a written employee health policy covering illness reporting, symptom monitoring, and when to exclude or restrict workers from food handling.6U.S. Food and Drug Administration. FDA Employee Health Policy Tool Employees must report specific symptoms — vomiting, diarrhea, jaundice, sore throat with fever — to the person in charge before starting a shift. Your state or local code may add requirements beyond the federal model. Inspectors will ask to see the written policy, and not having one is a citable violation.
Permits typically expire annually. Renewal usually involves paying the annual fee and passing a new inspection, and some jurisdictions want updated documentation if your menu, equipment, or commissary have changed. Keep commissary visit logs, temperature monitoring records, equipment maintenance records, and your employee health policy accessible in the truck. Inspectors can ask for them at any time.
One boundary worth stating plainly: your health permit authorizes food preparation and sale, but it does not control where you can park. Local zoning and right-of-way rules do that. Common restrictions include minimum distances from brick-and-mortar restaurants (often 200 to 600 feet), bans on operating in residential areas without property owner permission, time limits on how long you can stay in one spot, and streets closed to commercial vehicles. Some cities designate food truck zones with closing times or density caps. Violating zoning rules can bring fines or permit suspension even when your health permit is current, so check the rules for every location you plan to work before you commit to a route.
