Food Trucks, Catering Tents, and NFPA 96 Chapter 17: What Mobile and Temporary Cooking Operations Must Do

OPERATIONS & REGULATIONS · CHAPTER 17

A taco trailer on South Congress, a crawfish rig outside a Lafayette festival, a brisket truck at a Fort Worth brewery, a tent kitchen feeding a state fair for eleven days — every one of them is a commercial kitchen on wheels or under canvas, with a fryer and a flat-top and a propane cylinder a few feet from a line of customers. For most of NFPA 96’s history, the standard wasn’t written for them. Since the 2021 Edition, it has a chapter that is.

QUICK ANSWER

NFPA 96 Chapter 17, Mobile and Temporary Cooking Operations, was added in the 2021 Edition and carried into the 2024 Edition. It applies to food trucks, food trailers, concession carts, and temporary cooking under tents and canopies. The core requirements: any cooking that produces grease-laden vapors needs a listed exhaust hood and a listed fire-extinguishing system (UL 300 is the recognized test standard), plus a Class K portable extinguisher; LP-gas cylinders must be installed per NFPA 58, mounted securely to the exterior, with leak detection; the unit must keep a separation distance from buildings, tents, other vehicles, and combustibles (10 feet is the commonly adopted figure — confirm with your AHJ); generators and fuel need their own separation; and the exhaust system is inspected and cleaned on the same Chapter 12 schedule as a fixed kitchen — Table 12.4 puts most trucks on a quarterly cadence and high-volume or charbroiling trucks on a monthly one. Most Southwest cities require an annual fire inspection and permit for mobile food units, and operators who can’t produce a current service label and written cleaning report fail it.

1. Why NFPA 96 Needed a Mobile Chapter

Before 2021, a food truck lived in a gap. NFPA 96 was written for cooking operations in buildings. NFPA 1, the Fire Code, had an annex on mobile and temporary cooking that AHJs could adopt or ignore. NFPA 58 governed the propane. The result was that a truck in Austin, a truck in Houston, and a truck in Oklahoma City could face three different sets of rules, and a truck that passed inspection in one city could be shut down at a festival two hours away.

The 2021 Edition moved the mobile and temporary cooking provisions into NFPA 96 as Chapter 17 and gave them the force of the standard. Fire marshals across the Southwest now have a single reference for the truck court, the fairground, and the catering tent — and the inspections have become more consistent and, in most cities, more frequent.

The underlying fire problem hasn’t changed. A food truck concentrates everything that makes a commercial kitchen hazardous into about 150 square feet: open-flame appliances, a grease-loaded exhaust duct, pressurized LP-gas, a generator, and a crowd. There’s no sprinkler system, no rated duct enclosure, no fire-rated wall between the kitchen and the public. When a truck fire happens, it moves fast, and the people most likely to be hurt are the ones in line.

FIELD NOTE — THE PROPANE HEADLINES

The incidents that drove Chapter 17 into the standard were mostly propane events — cylinder leaks and explosions, not duct fires. The 2014 Philadelphia food truck explosion that killed two people and injured a dozen is the one most fire officials cite. But the exhaust system is the other half of the problem. A grease-loaded duct over a flat-top in a truck has no enclosure and often no more than a few feet of run before the fan; if a flare-up reaches it, the fire is on the roof almost immediately. Chapter 17 addresses both.

2. What Chapter 17 Covers

Chapter 17 applies to two categories of operation. The exact definitions are in the standard; in plain terms:

CATEGORY	WHAT IT MEANS	EXAMPLES
Mobile cooking operation	Cooking equipment on a vehicle or trailer designed to be moved — the kitchen travels with the truck	Food trucks, food trailers, concession trailers, towed smoker rigs, converted buses
Temporary cooking operation	Cooking equipment set up for a limited time at a location not designed as a permanent kitchen	Festival and fair cooking tents, event catering under canopy, pop-up kitchens, church and school fundraiser cooking, cook-off competitions

What Chapter 17 does not cover: a permanent kitchen inside a building, even if the restaurant also runs a truck. The building kitchen follows Chapters 1 through 16 and the standard NFPA 96 compliance picture. The truck follows Chapter 17 — and Chapter 17 reaches back into the rest of the standard for the parts that apply.

The chapter’s main provisions

1. AHJ permit and inspection. Mobile and temporary cooking operations are subject to the authority having jurisdiction’s permit requirements. In practice this means an annual fire inspection of the truck and an event permit for temporary operations.
2. Exhaust hood and fire-extinguishing system. Cooking equipment that produces grease-laden vapors must be under a listed hood and protected by a listed automatic fire-extinguishing system. The equipment must be installed per Chapters 5 through 10 of the standard as applicable. UL 300 is the recognized test standard for wet-chemical systems.
3. Portable extinguishers. A Class K extinguisher for cooking-oil fires, plus an appropriate extinguisher for the rest of the unit, per NFPA 10.
4. LP-gas. Cylinders installed per NFPA 58, mounted securely on the exterior of the unit in a ventilated location, with piping protected from damage, and a leak-detection system or alarm on the unit.
5. Carbon monoxide detection. A CO alarm inside the unit where fuel-burning appliances or generators are used.
6. Separation distances. The unit must be separated from buildings, tents, canopies, other vehicles, and combustible materials, with the exception of serving awnings and similar attachments. Ten feet is the figure most AHJs enforce; confirm locally.
7. Generators and fuel. Generators placed away from the unit and from the public, with fuel storage kept to what the operation needs and refueling done only when the generator is off and cool.
8. Training. Operators and staff trained on the fire-extinguishing system, on shutting off fuel and power, and on evacuating the unit.
9. Inspection, cleaning, and maintenance. The exhaust system is inspected, cleaned, and maintained per Chapter 12 — the same chapter that governs every fixed commercial kitchen. The suppression system is serviced semiannually per Chapter 11 and NFPA 17A.
10. Solid fuel. A truck or trailer that burns wood or charcoal — a towed smoker, a wood-fired pizza trailer — also has to meet the applicable parts of Chapter 14. See our post on solid-fuel cooking and Chapter 14.

3. The Exhaust System: Same Rules, Smaller Box

The part of Chapter 17 that most mobile operators underestimate is the one that points back to Chapter 12. The hood over the fryer in a truck is a Type I hood collecting grease-laden vapors. It is inspected on the Table 12.4 schedule and cleaned to bare metal under Section 12.6.5, exactly like the hood in a brick-and-mortar kitchen. The truck doesn’t get a lighter standard because it’s small.

TRUCK TYPE	COOKING PROFILE	TABLE 12.4 CATEGORY	INSPECTION CADENCE
Towed smoker / barbecue rig	Solid fuel	Solid-fuel cooking operations	Monthly
Burger / charbroil / wok truck, full daily service	Charbroiling, wok cooking, 24-hour or high-volume	High-volume	Monthly
Taco, fry-heavy, flat-top truck, daily service	Griddle, fryer, moderate volume	Moderate-volume	Quarterly
Weekend-only or event-only truck	Intermittent, moderate equipment	Low-volume	Semiannually
Coffee, dessert, or cold-prep trailer with no grease-producing appliance	No grease-laden vapors	Outside Chapter 17 hood requirements	N/A — check with AHJ

Two things change the math for a truck. First, the duct run is short — often a few feet from the hood to a roof-mounted fan — so grease that would spread across thirty feet of horizontal duct in a restaurant concentrates in a very small system and reaches the cleaning threshold quickly. Second, the fan is right there on the roof above the cook, with no curb or containment, which means grease discharge lands on the truck roof and runs down the sides. Our posts on grease thickness thresholds and inspection vs. cleaning cover how the threshold works; in a truck, the inspection is faster and the answer is “clean it” more often.

What a compliant truck cleaning includes

• Hood interior and plenum cleaned to bare metal, baffle filters removed and the filter track cleaned
• Full duct run cleaned to bare metal — short as it is, every inch, including the transition to the fan
• Roof fan cleaned, including blades, housing, and the underside; fan tilted or removed if hinged
• Grease discharge on the roof surface cleaned and the roof checked for grease migration toward the propane cylinders or generator
• Suppression nozzles wiped and their caps verified in place — not serviced, which is the suppression contractor’s work
• Service label applied per Section 12.6.13 showing the company, the technician, and the date
• Written report per Section 12.6.15, including any areas not cleaned and any deficiencies found

THE PERMIT-RENEWAL TEST

When the fire inspector walks the truck, the first two things checked are the suppression tag and the hood cleaning label. If the label is missing, expired, or doesn’t match the cadence for the truck’s cooking profile, the inspection stops there. The written report is what gets the permit back.

4. How Southwest Cities Enforce It

Chapter 17 is enforced through each state’s adopted fire code and each city’s mobile food vendor program. The structure is the same everywhere — the health department permits the food handling, the fire department permits the fire safety — but the details vary. Our state-by-state fire code adoption guide covers which edition of NFPA 96 each state has adopted; the local picture for mobile units generally looks like this:

MARKET	WHAT TO EXPECT	SERVICE AREA
Austin	The Austin Fire Department runs a dedicated mobile food vendor fire permit program with an annual inspection; Austin has one of the largest truck populations in the country and inspectors are experienced with Chapter 17	Austin
Houston	Houston Fire Department permits mobile food units using propane; the city has specific rules on where propane-fueled trucks can operate downtown	Houston
Dallas – Fort Worth	Both cities inspect mobile units through their fire prevention divisions; truck parks and brewery lots in Fort Worth and Dallas are inspected as temporary assembly venues as well	Fort Worth · Dallas
San Antonio	Fire inspection is part of the mobile food vendor permit; Fiesta and other large events bring temporary cooking enforcement	San Antonio
Oklahoma City and Tulsa	Mobile units permitted through the fire marshal’s office; Oklahoma’s adopted fire code applies statewide with local amendments	Oklahoma City · Tulsa
New Orleans, Baton Rouge, Lafayette	The Louisiana Office of State Fire Marshal has statewide jurisdiction and inspects mobile units directly; festival season brings heavy temporary cooking enforcement	New Orleans · Baton Rouge · Lafayette
Albuquerque and Santa Fe	Permitted through the city fire marshal; the New Mexico State Fire Marshal covers unincorporated areas and state events	Albuquerque · Santa Fe
Northwest Arkansas and Little Rock	Mobile units permitted locally under the Arkansas Fire Prevention Code; Fayetteville and Bentonville have active truck scenes with regular inspection	Fayetteville

Confirm the specifics with the fire prevention office in each city where the truck operates. A truck that works Austin on weekdays and a Hill Country festival on weekends answers to two AHJs, and the stricter one sets the bar.

FIELD NOTE — THE FESTIVAL WALK-THROUGH

At a large festival, the fire marshal’s team walks the vendor row before gates open. They check every truck and tent in sequence: propane cylinder mounting and leak test, suppression tag, hood label, Class K extinguisher, separation from the next unit, generator placement. A truck that fails is told to fix it or leave — before a single customer has paid. Operators who travel the festival circuit learn to carry the written cleaning report in the truck, because an inspector at an event in a city where the truck has never been permitted has nothing else to go on.

5. Temporary Cooking: Tents, Fairs, and Events

Temporary cooking under a tent is in some ways the harder case. The truck at least has a hood and suppression built in. A catering tent at a wedding or a cook-off booth at a fair often starts as a table and a burner with nothing over it.

Chapter 17 draws the line at grease-laden vapors. If the temporary operation fries, griddles, or charbroils, it produces grease-laden vapors and needs a listed hood and suppression system — which, for a tent, means a portable hood unit with integrated suppression, or cooking on a trailer that already has one. Warming, holding, boiling, and steaming without grease production generally fall outside the hood requirement, though the AHJ, LP-gas, and separation rules still apply.

Common temporary cooking situations in the Southwest

• Crawfish boils and seafood boils — boiling, no grease-laden vapors; LP-gas and separation rules apply, hood generally not required
• Fish fry fundraisers — deep frying produces grease-laden vapors; hood and suppression required under Chapter 17, which is why many churches and organizations now rent a fry trailer instead of setting up open fryers
• Barbecue cook-offs — solid-fuel smokers fall under Chapter 14 provisions; competition organizers increasingly require a spark arrestor and extinguisher at every pit
• Fair and festival food booths — funnel cakes, corn dogs, and turkey legs all involve frying; the booth needs a hood and suppression or has to be a trailer
• Catered events under tents — action stations with griddles or sauté burners are grease-producing; caterers in large markets now bring portable hood units
• Tailgating — generally personal rather than commercial, but a sponsored or sold-to-the-public tailgate cook is a temporary cooking operation

Temporary operations also have to think about where the grease goes afterward. A portable hood that’s cleaned once a season is a grease-loaded hood for eleven of twelve months. Caterers and event vendors should have their portable units inspected and cleaned on the same cadence logic as a truck — by cooking volume and hours of use, not by the calendar.

6. Who Does What on a Food Truck

A truck has the same three-vendor structure as a restaurant, compressed into a vehicle. Keeping the roles straight is what keeps the permit current.

SYSTEM	WHO SERVICES IT	CADENCE	WHAT THE INSPECTOR LOOKS FOR
Hood, duct, roof fan	Certified kitchen exhaust cleaning contractor	Table 12.4 — monthly to semiannually by cooking profile	Service label on the hood; written report available
Fire-extinguishing (suppression) system	Licensed fire suppression contractor	Semiannual per Chapter 11 and NFPA 17A	Current inspection tag; nozzle caps in place; manual pull accessible
Portable extinguishers	Licensed extinguisher service company	Annual inspection; monthly visual by operator	Class K within reach of the cookline; tags current
LP-gas system	Licensed LP-gas installer / propane supplier	Leak test at inspection; after any cylinder change or line work	Exterior mounting, secure, leak detector functioning, no damaged lines
Generator and electrical	Licensed electrician; generator service tech	Per manufacturer	Placement, grounding, fuel storage, cords not creating trip hazard
CO alarm	Operator	Monthly test; battery per manufacturer	Present and functioning

Facilitec Southwest cleans the exhaust system — hood, duct, and fan — and delivers the Section 12.6.13 label and Section 12.6.15 report. We don’t service the suppression system, the propane, the generator, or the electrical; those belong to their licensed trades, and we’ll tell you when we see something in those systems that needs attention. Our post on fire suppression systems and NFPA 96 explains the suppression side in detail.

SIGNATURE APPROACH

From Cooktop to Rooftop is a short trip on a food truck, and our Phil Ackland Certified Technicians make it in one visit — hood, duct, roof fan, and the grease on the roof surface, cleaned to bare metal, labeled, and documented so the truck passes its next permit inspection. The outcome is a Grease-Free and Fire-Safe mobile kitchen, and the peace of mind that comes with it when the fire marshal walks the vendor row.

7. The Food Truck Compliance Checklist

For operators preparing for an annual fire inspection or a festival permit, the Chapter 17 picture reduces to a list. Keep it in the truck.

1. Hood cleaning service label on the hood, dated within the Table 12.4 cadence for the truck’s cooking profile.
2. Written cleaning report from the most recent service, in the truck.
3. Suppression system tag current within six months, nozzle caps in place, manual pull station unobstructed.
4. Class K extinguisher mounted within reach of the cookline, tag current; a second ABC extinguisher for the rest of the unit.
5. LP-gas cylinders mounted on the exterior, secured, with protective covers; lines inspected for damage; leak detector powered and functioning.
6. CO alarm inside the unit, tested.
7. Generator positioned away from the unit and the public, fuel stored in approved containers, no refueling while running.
8. Separation — the unit parked at the required distance from buildings, tents, other trucks, and combustibles; serving awning the only attachment.
9. Staff training — every person who works the truck can operate the suppression pull, shut off the propane at the cylinder, and kill the generator and electrical.
10. Roof surface — grease discharge from the fan cleaned off; no grease migration toward the cylinders or generator.
11. Solid fuel (if applicable) — spark arrestor on the smoker stack, ash handling and fuel storage per Chapter 14.
12. Permits — current fire permit for the home city, event permit for any temporary location, health permit current.

Frequently Asked Questions

Does NFPA 96 apply to food trucks?

Yes. Since the 2021 Edition, NFPA 96 Chapter 17, Mobile and Temporary Cooking Operations, applies to food trucks, trailers, carts, and temporary cooking under tents. It requires a listed hood and fire-extinguishing system over grease-producing equipment, Class K extinguishers, LP-gas installation per NFPA 58, CO detection, separation distances, and inspection and cleaning of the exhaust system per Chapter 12 and Table 12.4.

How often does a food truck hood need to be cleaned?

On the Table 12.4 schedule, by cooking profile. A full-service truck with a griddle and fryer is typically moderate-volume and inspected quarterly; a charbroiling, wok, or high-volume truck is monthly; a towed smoker burning wood is monthly as solid fuel; a weekend-only truck may be semiannual. Cleaning follows when the inspection finds grease at the Section 12.6.1.1 threshold — which, in a short truck duct, is often.

What is the separation distance for a food truck under NFPA 96?

Chapter 17 requires separation from buildings, tents, canopies, other vehicles, and combustible materials. Ten feet is the figure most AHJs in the Southwest enforce. Serving awnings and similar attachments are typically excepted. Confirm the exact requirement with the fire prevention office in each city where the truck operates, because local amendments vary.

Does a food truck need a UL 300 suppression system?

Chapter 17 requires a listed automatic fire-extinguishing system over cooking equipment that produces grease-laden vapors. UL 300 is the recognized test standard for wet-chemical kitchen suppression systems. The system is serviced semiannually by a licensed suppression contractor per Chapter 11 and NFPA 17A. This is separate from the hood cleaning — different vendor, different license, different tag.

Do I need a hood for a crawfish boil or a catering tent?

The hood requirement is triggered by grease-laden vapors. Boiling, steaming, and warming without grease production generally do not require a hood, though LP-gas, separation, and permit rules still apply. Frying, griddling, and charbroiling under a tent do produce grease-laden vapors and require a listed hood and suppression system — which is why portable hood units and fry trailers have become standard at Southwest festivals and fundraisers.

Where are the propane cylinders supposed to be on a food truck?

On the exterior of the unit, securely mounted in a ventilated location, protected from damage, with piping installed per NFPA 58 and a leak-detection device on the unit. Cylinders inside the truck or in an enclosed, unventilated compartment are the most common serious deficiency fire inspectors find.

What will the fire marshal check at a food truck inspection?

Hood cleaning service label and written report; suppression system tag, nozzle caps, and pull station; Class K and ABC extinguishers; LP-gas cylinder mounting, lines, and leak detector; CO alarm; generator placement and fuel storage; separation distance; and that the staff can operate the suppression and shut off fuel and power. Solid-fuel units are also checked for a spark arrestor and ash handling.

Does a barbecue trailer with a wood smoker fall under Chapter 17 or Chapter 14?

Both. Chapter 17 applies because it’s a mobile cooking operation; the applicable provisions of Chapter 14 apply because it burns solid fuel. Expect a spark arrestor requirement on the stack, ash handling and fuel storage rules, and the monthly Table 12.4 cadence for solid-fuel operations. Our solid-fuel post covers Chapter 14 in detail.

My restaurant also runs a truck. Is it covered by the restaurant’s hood cleaning contract?

Only if the contract says so. The building kitchen and the truck are separate systems with separate Table 12.4 cadences, separate service labels, and separate written reports. Many operators add the truck to the restaurant’s maintenance program so both are documented in one file — but it has to be written in, and the truck has to be available at the shop or the commissary when the technician arrives.

Can a food truck pass inspection without a written cleaning report?

Usually not. The service label on the hood establishes that a cleaning happened; the written report per Section 12.6.15 establishes what was cleaned, what wasn’t, and whether deficiencies were found. Inspectors in most Southwest cities ask for both at permit renewal, and inspectors at events in a city where the truck has no permit history rely on the report entirely.

Who cleans the grease off the roof of the truck?

The exhaust cleaning contractor, as part of the fan service. A truck fan discharges grease directly onto the roof surface with no curb or containment, and the grease runs toward whatever is downhill — sometimes the propane cylinder mounts. Cleaning the roof surface and checking for migration is part of a complete truck service. Grease containment systems built for rooftop fans don’t typically fit a truck, so roof cleaning at each service is the practical control.

How does Facilitec Southwest service food trucks?

We inspect and clean the hood, duct, and roof fan to bare metal at your commissary, shop, or truck park, clean the roof surface, apply the Section 12.6.13 service label, and deliver the Section 12.6.15 written report for your permit file. Trucks can be added to a restaurant’s existing maintenance program. We don’t service suppression, propane, generators, or electrical — those belong to their licensed trades — and we’ll flag anything in those systems we see. Service across TX, OK, LA, NM, and AR.
