The fastest way to lose your first few weeks in business is to fail inspection and have to fix and re inspect, and almost all of it is avoidable. Inspections are not a mystery. They come down to a predictable set of items, and a truck that is built right and an owner who shows up prepared pass the first time. This is a full breakdown of what inspectors actually look at, why each item is there, and where new owners trip.

One note before the lists. The exact rules vary by city and state, so always confirm the specifics with your local health department and fire authority. The items below are the common requirements that appear almost everywhere, drawn from the FDA Food Code that most states adopt and from the standard fire code provisions for mobile cooking. Use this as the master checklist, then layer your local details on top.
The health inspection
A health inspector is verifying that you can receive, store, handle, and serve food safely out of a mobile kitchen. These are the items that come up almost every time.
A separate handwashing sink, supplied with hot and cold running water, soap, and paper towels, and kept only for handwashing. Inspectors look for this early, and a missing, blocked, or undersized hand sink is one of the most common single reasons trucks fail. Handwash water generally needs to reach at least 100 degrees.
A three compartment sink with drainboards for washing, rinsing, and sanitizing utensils and equipment, unless your menu is limited enough to qualify for an exemption in your jurisdiction. Limited menu and prepackaged operations sometimes get a pass on this, but you have to confirm that you qualify rather than assume it.
A potable water tank fed from an approved source, and a wastewater tank that is larger than the fresh water tank. Many states require the wastewater tank to be at least 15 percent larger than the fresh tank, so that you physically cannot generate more waste than you can legally hold. Wastewater has to be discharged to a sanitary sewer, never onto the ground or into a storm drain, and inspectors do check this.
Refrigeration that holds cold food at or below 41 degrees and hot holding that keeps hot food above 135 degrees, with a working thermometer to prove it. These two numbers, 41 and 135, are the heart of food safety, and inspectors commonly check holding temperatures on the spot, so your equipment has to actually hold them under real conditions, not just on paper.
Food contact surfaces that are smooth, nonabsorbent, and cleanable, which in practice means commercial, NSF rated stainless steel rather than household grade materials. This is the kind of thing that is cheap to build right and expensive to retrofit.
A commissary or base of operations, where your jurisdiction requires one, with the agreement in writing if you share a kitchen. Many states waive this for a fully self contained truck that can wash and store everything on board, but you need to know which rule applies to you before you build, because it changes the truck.
Your plan review approval and your license paperwork on hand. A large share of cities require that the truck’s construction be reviewed and approved before you build it, and they will not license a truck that skipped that step. Skipping plan review is one of the most expensive mistakes a new owner can make, because the fix can mean rebuilding part of the kitchen.
The fire inspection
A fire inspector is focused on your cooking equipment, your fuel, and what happens if something ignites. These items come from the fire code provisions for mobile food preparation vehicles, which most jurisdictions enforce through some version of the International Fire Code.
A Type I hood over any cooking that produces grease laden vapor, paired with an automatic fire suppression system. Modern suppression systems are built and listed to the UL 300 standard, and the system has to be professionally serviced and tagged on a schedule. An expired suppression tag is an easy and common failure.
A Class K fire extinguisher for cooking grease fires, in addition to a general purpose extinguisher for ordinary combustibles. Both need current service tags and have to be mounted where the code requires, not loose in a cabinet.
Propane within the allowed limit. In most jurisdictions the aggregate cap is 200 pounds of propane for cooking fuel, with cylinders securely mounted, built and installed to the propane code, and a listed gas leak alarm inside the vehicle. Oversized, loose, or poorly mounted propane setups are one of the most frequent fire failures, and they are exactly the kind of thing a cheap build or an old used truck gets wrong.
Clearances kept around cooking equipment and around any generator, and the hood and ducts cleaned on the schedule your cooking volume calls for. High volume frying needs more frequent cleaning than occasional griddle work, and the inspector knows the difference.
Your fire inspection sign off, which in many cities has to be completed and submitted to the health department before your license is final. The two inspections are often linked, so a fire problem can hold up your whole license.
The most common reasons trucks fail
If you want to pass the first time, it helps to know where others do not. The repeat offenders are a missing or inadequate handwashing setup, refrigeration that cannot hold 41 degrees under load, an expired or missing fire suppression tag, a propane system that is oversized or not properly mounted, a wastewater tank that is not larger than the fresh tank, food contact surfaces that are not commercial grade, and, the most expensive of all, a truck that was built without going through required plan review. Notice that nearly every one of these is a build decision, not an operating decision, which is the whole reason the build matters so much.
How to actually pass the first time
Three things make the difference. First, build to your local code from the start rather than fixing it after the fact, because a truck built for the wrong city, or bought used and built to an older code, is the most expensive kind of mistake to unwind. Second, go through plan review before you build, wherever your jurisdiction requires it, so the people who will inspect you have already approved your design on paper. Third, show up prepared on inspection day. Have your paperwork in hand, your suppression and extinguisher tags current, your tanks filled, and your refrigeration already running at temperature, so the inspector can verify holding on the spot instead of asking you to come back.
This is the part we handle for the trucks we build. We prepare the plan review packet for your specific health authority, build the kitchen to the FDA Food Code your state adopts, and build the cook line and fuel system to fire code, so the truck is ready to pass both health and fire the first time. Most of our customers clear inspection on the first try, which is the entire point of building it right.

Frequently asked questions
What do food truck health inspectors check?
A separate handwashing sink with hot water, a three-compartment sink, potable and wastewater tanks with the waste tank larger than the fresh, refrigeration holding at or below 41 degrees and hot holding above 135, NSF food-contact surfaces, a commissary where required, and your plan review and license paperwork.
Why do food trucks fail inspection?
The repeat offenders are a missing or inadequate handwashing setup, refrigeration that cannot hold 41 degrees under load, an expired or missing fire suppression tag, an oversized or poorly mounted propane system, a wastewater tank that is not larger than the fresh tank, non-commercial surfaces, and skipping required plan review. Nearly every one is a build decision.
How big does my wastewater tank need to be?
Many states require the wastewater tank to be at least 15 percent larger than the fresh water tank, so you physically cannot generate more waste than you can legally hold. Waste must go to a sanitary sewer, never the ground or a storm drain.
Do I need a fire suppression system on a food truck?
Yes, over any cooking that produces grease-laden vapor. You need a Type I hood with an automatic suppression system listed to UL 300, professionally serviced and tagged, plus a Class K extinguisher and a general-purpose extinguisher.
What temperature does food truck refrigeration need to hold?
Cold food at or below 41 degrees and hot holding above 135 degrees, with a working thermometer to prove it. Inspectors commonly check holding temperatures on the spot.
