Who issues health permits, what inspectors actually check, how to pass your first inspection, and what gets permits denied or revoked.
The Basics
A food truck health permit (formally called a Mobile Food Unit license, Mobile Food Establishment permit, or Food Service Operation license depending on your state) is the government authorization to legally sell food from your truck. Without it, you cannot legally operate — and in most jurisdictions, operating without one results in immediate shutdown and significant fines.
Health permits are issued by one of three authorities depending on your state: (1) the state health department or department of agriculture, (2) the county health department, or (3) the city health department. Some jurisdictions require permits from multiple levels — for example, a Chicago operator needs both a state Illinois Food Service Sanitation license and a Chicago BACP Mobile Food Dispenser license.
The permit must be renewed annually in most states, and your truck may be subject to unannounced inspections at any time during the year.
The Inspection
Temperature control equipment
Refrigeration units must reach and hold 41°F or below. Hot holding equipment must maintain 135°F or above. Inspectors will verify this with calibrated thermometers. Equipment that can't hold temperature is an immediate fail.
Hand-washing station
A dedicated hand-washing sink with hot and cold running water, soap dispenser, and paper towels is required — separate from food prep sinks. In many trucks this is the most commonly failed item because the sink is too small or lacks consistent hot water.
Food storage and labeling
Raw proteins must be stored below ready-to-eat foods. Everything must be labeled with the open date. Nothing on the floor. Inspectors specifically look at how you store raw chicken vs. produce.
Surface materials
All food contact surfaces must be smooth, non-porous, and easily cleanable (typically stainless steel). Inspectors will look for cracks, rust, or non-compliant materials.
Ventilation and grease management
Adequate ventilation is required for any cooking. A grease trap or grease interceptor may be required depending on your menu. Fire suppression systems over open-flame cooking are required in most jurisdictions.
Pest and contamination prevention
No gaps where pests can enter. All food must be covered. Chemicals stored separately from food. Inspectors look for evidence of pest activity.
Water supply and wastewater
You must have an approved potable water supply (either a connected city hookup or an onboard fresh water tank). Wastewater must go to an approved grey water tank or hookup — not on the ground.
Passing First Time
The most important thing you can do before your inspection is request a pre-inspection consultation with your local health department. Most jurisdictions offer these. Bring your truck, walk through it with an inspector, and ask them to identify any issues. It costs nothing and eliminates surprises.
Second, study the actual inspection form your jurisdiction uses. Most health departments publish their inspection criteria online. The form tells you exactly what they're looking for — build your prep process around it.
Third, do a self-inspection the day before using the department's form. Have someone else go through the checklist while you're outside the truck so they can catch things you've stopped noticing.

Common Failures
The most common reasons for permit denial are: no valid commissary agreement (you cannot get a mobile food unit permit without one in most states), refrigeration that doesn't maintain proper temperatures, and hand-washing sinks that don't have consistent hot water.
Revocations during the operating season typically result from: failure to renew your commissary agreement, a failed surprise inspection (often temperature violations), operating in a jurisdiction where you don't have a permit, or food safety incidents.
If your permit is denied, ask the inspector for a written list of deficiencies. Fix each item, document the fix, and request a re-inspection. Most jurisdictions allow multiple re-inspections — being proactive and communicating with the inspector goes a long way.
Pro Tip
The permit process is the barrier to entry. But the operators who build sustainable businesses are the ones who solve the second problem: making sure their customers know when and where to find them. A QR code at your window and a text list is the simplest version of that system.
