Food Truck Licensing and the Commissary Requirement: What's Actually Different About a Mobile Permit

Before most health departments will issue your mobile food permit, they want a signed agreement with a commissary — a permitted facility your truck returns to for potable water fill, wastewater discharge, cleaning, ice, and food storage. Most first-time operators have never heard the word until an application comes back marked incomplete, usually after they've committed to a truck and a build slot. Industry sources put basic shared-kitchen access around $250 to $1,000 a month. It's a recurring line item and, in many jurisdictions, a hard gate: no agreement, no permit.

A truck's permit path isn't a smaller version of a restaurant's. It's a different shape, because the facility itself moves. The full restaurant permits checklist maps the sequence every food business runs — entity, tax registration, zoning, health, fire. This guide covers what changes for a truck: the commissary agreement, vehicle registration, propane and fire inspection, what a mobile plan review adds, and why working three cities means three sets of paperwork.

Why a Food Truck's Permit Path Isn't a Small Restaurant's

Three structural differences drive everything downstream.

There's no certificate of occupancy. A restaurant's buildout ends with a single sign-off on a fixed space, and in most jurisdictions the food permit won't issue without it. A truck has no such keystone. The vehicle is the facility, so instead of one terminal approval you get a recurring one: the unit is inspected, permitted, and re-inspected on a cycle, often annually. Your approval is a repeat performance, not a finish line.

At least four separate authorities are involved, with no shared intake. Each has its own application, fee, and calendar, and no obligation to tell the others what you've done.

Working multiple cities multiplies the city layer specifically. A restaurant deals with one municipality forever. A truck running a Tuesday lot downtown, a Thursday brewery in the next city, and weekend events in a third is running three municipal onboarding projects, each with its own fee and renewal date. That's a cost structure a fixed restaurant never faces, and the one most commonly missing from a first-year budget.

The rest of this guide is organized by agency rather than chronology, because that's how you'll experience it — four parallel conversations, not one queue.

The Commissary Requirement

What a commissary is, and why it's usually mandatory

A commissary is a permitted, inspected commercial food facility your mobile unit is formally linked to. The functions are consistent across jurisdictions even where the rules differ: potable water fill, wastewater discharge to an approved sewer connection, washing and sanitizing equipment that can't be adequately cleaned onboard, ice, and dry and cold storage between service days.

The requirement traces back to the FDA Food Code's treatment of mobile units, which assumes a servicing area and a base of operations rather than a self-contained kitchen. Some states write the linkage into statute: California's Health and Safety Code §113831 defines a mobile food facility as a vehicle operated in conjunction with a commissary or other permanent food facility. That's California's language, not a national rule, but it shows how tightly some states bind the two.

A home kitchen essentially never qualifies. Residential kitchens aren't permitted food facilities, aren't inspected, and can't be cleaned into compliance. That's one of the few near-universal answers in mobile permitting, and it kills a plan a lot of first-time operators arrive with.

Whether a commissary is required at all, and which of those functions must happen there, is set by your county or state health agency and depends on your menu and onboard equipment. A truck with full onboard tanks, refrigeration, and a three-compartment sink may face a lighter requirement than a unit that preps offsite. Ask in those terms — "given this menu and this equipment list, what must happen at a commissary?" — not whether a commissary is required in general.

What the agreement actually commits you to

The commissary letter isn't a formality. It's a contract that sets your operating rhythm — read it like a lease. Four clauses carry the weight.

Access schedule. The hours you can be on site — the clause that quietly breaks routes. If you close at 10pm at a brewery and the commissary gates lock at 8pm, you're storing product and dumping waste somewhere that isn't in your permit. Check the hours against your actual service schedule, not your intended one.

Which services are included versus billed separately. Water fill and wastewater discharge are usually in the base fee. Grease disposal, dry storage, walk-in space, overnight parking, and dedicated cleaning bays are frequently add-ons. Get the itemization in writing — a $400 quote that becomes $900 once storage and parking are added is common and avoidable.

The fee structure. Monthly flat rate, hourly kitchen time, or a hybrid. Secondary industry sources put basic shared-kitchen access at roughly $250 to $1,000 per month and full-service arrangements with parking and storage at $1,000 to $3,000 per month, with Los Angeles, New York, and San Francisco clustering toward the top and mid-size markets lower. That's a wide secondary-source estimate, not a quote — get a local number before you build a pro forma. It belongs in your startup cost estimate as a recurring monthly line, closer to rent than to a permit fee.

That the commissary's own permit stays current. The clause people skip, and the one with the sharpest teeth. Your mobile permit is issued partly on the strength of your link to a permitted facility, so if the commissary lets its health permit lapse, your agreement can become worthless and your permit can go with it. Ask what notice you get, and what happens if they close.

Many health departments require the agreement re-verified annually rather than filed once, and frequently prescribe the letter's format — a generic tenancy letter gets rejected.

Vetting a commissary before you sign

This is the truck operator's version of pre-lease diligence. Run these before money moves:

• Is their health permit current, and does it cover the services I need? Ask to see it. A facility permitted for catering production may not be permitted as a mobile servicing area.
• Will they issue a letter naming my specific unit and menu? Health departments commonly want the VIN or unit identifier on it.
• Do their hours match my route, including late nights, weekends, and event days?
• How many trucks are on the agreement? Ten units sharing one water fill and one waste receptor at 9pm is a queue, and a queue is unpaid labor.
• Is there refrigerated and dry storage, and at what price? Storing product there rather than on the truck changes what commercial refrigeration you buy for the build.
• What's the cancellation notice, in both directions, and has the facility changed hands or had a permit action?

One adjacent question, because it comes up constantly: a commissary is not a ghost kitchen, and renting one doesn't give you a ghost kitchen license. A commissary services a mobile unit that sells elsewhere; a ghost kitchen produces food for delivery from that address, a different permitted activity. Some facilities offer both, and if you plan to run delivery orders out of the commissary between truck shifts, that's a separate conversation with the health department — ghost kitchen setup and delivery economics covers permitting inside someone else's facility and which agreement clauses carry the real exposure.

Vehicle Registration and DMV Requirements

This layer has nothing to do with food, and it catches people precisely because it feels unrelated. The truck is a vehicle. It has to be titled and registered like one, and once it's used commercially, that generally means a commercial registration class rather than a passenger one.

The one clean, non-jurisdiction-variable fact here is the CDL threshold. Under the federal FMCSA standard, a single vehicle with a gross vehicle weight rating of 26,001 lbs or more requires the driver to hold a commercial driver's license; at or below 26,000 lbs, weight alone doesn't trigger it. For a trailer setup the federal line is drawn on the combination — a gross combination weight rating above 26,000 lbs where the towed unit itself is rated over 10,000 lbs — so the tow vehicle's rating alone doesn't settle it. Most step-van and box-truck conversions sit under the line; heavier custom builds and gooseneck rigs can cross it. Check the GVWR on the door jamb sticker before you buy the chassis, because this is a hiring constraint as much as a paperwork one. If your build needs a CDL and your two employees don't have one, that's a staffing problem you didn't budget for.

Everything else here is state-set: registration class and fee are generally keyed to gross or combined gross weight, with 10,001 lbs a common threshold into commercial classes — California's DMV, as one state's example, runs commercial registration on that basis. Whether your state applies a separate safety inspection to a "mobile food unit" as its own vehicle class, whether commercial plates are required, and what the fees are, are questions for your state DMV or DOT.

Ask the DMV directly and don't let the health department answer for them. A truck can hold a current mobile food permit and be improperly registered, or the reverse, and you'll find out at a traffic stop or a renewal.

Fire Suppression and Propane Inspection for Mobile Units

The fire marshal — or whichever office is the authority having jurisdiction where you're based — runs its own inspection on its own cadence, separate from health plan review. Passing one tells you nothing about the other.

Propane systems on mobile food units fall under NFPA 58, which addresses mobile food facilities in Chapter 16 of the 2024 edition. Two things follow. First, cylinders have to stay within their DOT requalification date: 12 years from date of manufacture, then on a recurring cycle — commonly 5 years, though the interval depends on the requalification method, and the collar stamp gives you both the date and the method. A used truck frequently comes with cylinders already past due, cheap to fix and expensive to discover on inspection day. Check the stamp before you take delivery. Second, some jurisdictions require an annual propane system inspection report from a licensed LP-gas technician before the fire marshal's own inspection, not instead of it — southwest Idaho's mobile food unit inspection checklist is one published example.

The common baseline is a suppression system over the cooking line plus a Class K extinguisher for grease fires alongside a standard ABC unit. Suppression coverage is sized to the appliances under the hood, so changing your cooking lineup after approval can force a revision — read listings for hoods and fire suppression systems against your final appliance list, not your first draft. This section is about the inspection, not the build; outfitting the truck itself covers propane configuration, conversion, and generator sizing.

On approval you typically get a sticker or decal, and how long it's good for varies more than operators expect. Howard County, Maryland requires annual fire marshal re-inspection of mobile food vendors; Anne Arundel County, Maryland, the next county over, doesn't require an annual sticker renewal, allowing spot checks and updating the decal only when the vehicle's configuration changes. Two neighboring counties, two cadences. Yours is its own answer.

One more variable, separate from the inspection: onboard propane quantity limits are set by city ordinance and vary widely, and the limit that applies is the one where you're parked, not where you're permitted. The comparison table below shows how far apart two cities land on it.

Health Department Plan Review for a Mobile Unit

The process shape is the same one every food business goes through — submit a plan, get it approved, get inspected, get permitted — and working with your health department covers that shared process, the packet discipline, and what to do when something gets rejected. What's different in a mobile review is the content.

The plan is a vehicle schematic, not a room. You're submitting an interior layout with equipment placement, plus plumbing and electrical views. Dimensions are tighter and clearances get scrutinized harder, because there's no option to move a wall.

Tank sizing is a hard spec, and it's mobile-only. A very common requirement: the wastewater holding tank must be at least 15% larger in capacity than the freshwater tank, with a sloped drain (typically one inch or greater) and a shutoff valve. Everything you take on has to come off, plus margin. That 15% figure appears in mobile food facility construction guidelines across many jurisdictions, but it's a common spec rather than a guaranteed one — confirm the ratio, the minimum tank volumes, and the drain requirements with your reviewer before the build, because retrofitting tanks in a finished truck is real work.

Onboard sinks are checked in the same review. A dedicated handwash sink separate from warewashing is nearly always required, and three-compartment sink requirements apply to most mobile units, with the configuration keyed to your menu. Settle the handwash and three-compartment sinks on the plan rather than fitting them in later. The reviewer looks up your equipment models the same way they would for a restaurant, which is why nameplates matter on used gear — which certifications actually matter covers what NSF, UL, and ETL marks do and don't prove.

Mobile approval is two-stage. A paper plan review before the build, then a physical inspection of the finished, driveable vehicle before the permit issues — a second full inspection cycle a fixed kitchen's single pre-opening walkthrough doesn't have, often at a designated site on a limited schedule. Find out early how far out it books: it sits between build completion and your first day of revenue. Then plan on annual renewal with a fresh inspection.

Per-City Vending Permits

The misconception that costs the most: a county health permit authorizes the food safety of your operation. It does not authorize your right to park and sell in a given city. A clean health permit is no defense against a vending citation. Most cities layer their own vending permit or business license on top, each with its own application, fee, term, and sometimes its own inspection. Some offer reciprocity with a neighboring jurisdiction; most don't. An operator working three cities is running three applications on three calendars.

The far end of the spectrum is New York City, where full-term Mobile Food Vending Unit permits are capped in number and issued through a waitlist or lottery, the waitlist has been effectively frozen for years with reported waits stretching a decade or more, and permits are largely non-transferable. That's NYC's system specifically and it's the extreme, cited so you know permit scarcity exists — not because it's the norm. The common pattern is an annual city vending permit with a modest fee, sometimes handled at the same counter as a general business license.

So: build around one home base city or county, get fully permitted there, and treat every additional city as its own onboarding project with its own timeline. Call before you plan the route, not after — discovering a six-month queue once you've booked a standing lot is a much worse version of the same conversation.

Sales tax follows the same logic. A route crossing city or county lines can mean collecting and remitting at different rates to different authorities. The restaurant permits checklist flags it; the resolution is a CPA who works in your state, not a blog post.

Parking and Proximity Rules

Even with a city vending permit in hand, where you can stop is governed by its own rules. The categories recur almost everywhere: a buffer from brick-and-mortar restaurant entrances, a distance from intersections, a time limit per spot, a relocation distance once that limit expires, and sometimes a public restroom within a set distance. The numbers behind them are not consistent, which is why memorizing one city's is worse than useless. Two labeled examples show the spread:

Los Angeles rules come from the city's mobile vending regulations; Chicago's are covered in the permits checklist and aren't re-derived here. These are two cities' ordinances, not a national standard. A 100-foot buffer in one and 200 feet in the other means the same parking spot is legal in one place and a citation in the other.

Your answer comes from your own city's mobile vending ordinance — usually findable by searching your city name plus "mobile food vehicle ordinance" — and a call to the city clerk or business licensing office to confirm the current version. Do that before you commit to a lot, a lunch route, or a standing arrangement with a business that offered you its parking lot. Private property doesn't exempt you from a city's vending rules in most places, and the property owner is rarely the one who knows.

Event and Festival Permitting

A standing mobile permit does not carry over to a festival, farmers market, or private event. Those run under a separate temporary food establishment (TFE) or temporary event permit tied to that specific event, generally shorter in duration and frequently on its own fee schedule.

County programs commonly require the event organizer to notify the health department in advance — 30 days is a figure that recurs in temporary-event programs, offered as an order of magnitude rather than a rule — and the vendor application often runs through the organizer rather than directly to the agency. Your deadline is the organizer's deadline minus their processing time, which is earlier than you'd guess. Ask the organizer which health jurisdiction the event sits in and what date they need you by.

Event vendors are also asked, nearly universally, for a certificate of insurance — commonly a $1,000,000 general liability minimum, naming the organizer or venue as additional insured. That figure is a widely observed pattern in vendor agreements, not a legal requirement, and what your policy needs is a conversation with your insurance agent. Plan around the lead time: additional-insured status comes from an actual endorsement on the policy, not a line typed into the certificate, and it's frequently the longer pole of the two — the event permit clears faster than the paperwork proving you're insured. Restaurant insurance, coverage by coverage covers how to read a certificate and what to ask a broker for.

Larger festivals can add a fire marshal walkthrough or a fire-watch requirement on site, on top of the propane inspection you already passed at home. Ask the organizer what fire authority has jurisdiction over the event grounds, because it isn't always the one that inspected your truck.

Event revenue is often what makes a truck's math work, and losing a booked weekend to a certificate that didn't arrive is an expensive administrative failure.

Building Your Multi-Agency Checklist

This survives every jurisdictional difference above. Work it by office, write down who told you what and when, and you'll have your actual permit path inside a week or two.

County or city health department

1. Given this menu and this equipment list, is a commissary required — and what exactly must the agreement specify and who has to sign it?
2. What's in your mobile plan review packet, including tank sizing ratios, drain specs, and sink requirements?
3. Is the finished-vehicle inspection a separate step from the paper plan review, how is it scheduled, and how far out is it booking?
4. Does my permit renew annually, does renewal require a fresh inspection, and what changes trigger a re-review mid-term?
5. Does this permit authorize me in neighboring counties, or do I need to apply separately there?

Fire marshal or AHJ

6. What's your propane inspection cadence, and do you require a licensed LP-gas technician's report before your own inspection?
7. What suppression system and extinguisher classes do you require over my cooking line?
8. What's the onboard propane quantity limit here, and does the sticker you issue expire?

State DMV or DOT

9. What registration class applies at my vehicle's GVWR, and what does it cost annually?
10. Is a separate state safety inspection required for mobile food units as a vehicle class?
11. Does my finished build — or my trailer-and-tow-vehicle combination — cross the CDL threshold?

Each city you plan to vend in

12. Do you require your own vending or business license on top of my county health permit?
13. What are your parking, proximity, time-limit, and relocation rules, and where's the current ordinance text?
14. Is there a permit cap, lottery, or waitlist I should know about before I plan a route here?

Event organizers and your insurance agent

15. What certificate of insurance and additional-insured endorsement do you require, and by what date?
16. How much lead time does my carrier need to issue that endorsement and certificate?

Keep the answers in one document with names and dates attached. When two agencies contradict each other — and they will — being able to say who told you what, and when, is the difference between a five-minute correction and a rebuild.

Frequently Asked Questions

Do I need a commissary kitchen for my food truck?

In most jurisdictions, yes — and a signed commissary agreement is often a condition of getting your mobile permit issued at all, not something you sort out afterward. Whether one is required, and which functions have to happen there, depends on your county or state health agency, your menu, and your onboard equipment. Ask in those specific terms, because a truck with full tanks and onboard warewashing sometimes faces a lighter requirement than one that preps offsite.

What does a food truck commissary agreement actually include?

Typically your access hours, which services are in the base fee versus billed separately (water fill and wastewater discharge are usually included; grease disposal, storage, and overnight parking often aren't), the fee structure, and a requirement that the facility's own health permit stays current. That last one matters more than it looks: if the commissary loses its permit, your agreement can become worthless and your mobile permit can follow. Many health departments prescribe what the letter must say and require annual re-verification, so ask yours for the format before you get a generic letter signed.

Can I use my home kitchen as my food truck's commissary?

Essentially never. Residential kitchens aren't permitted, licensed, or inspected food facilities, and there's no practical way to bring one into compliance for this purpose — one of the few near-universal answers in mobile permitting. If cost is the driver, price shared commercial kitchens, churches and community centers with permitted kitchens, restaurants with off-hours capacity, and dedicated commissaries. The range across those options is wide, and off-peak time in an existing restaurant is often the cheapest legitimate path.

Do I need a separate permit for every city I want to sell in?

Usually yes at the city level, even though your county health permit travels with you inside its own county. That health permit certifies the food safety of your operation; it says nothing about your right to park and sell in a particular city. Most cities layer their own vending or business license on top, with their own fee and term, and reciprocity between neighbors is the exception. Call each city before you plan a route there: does a permit exist, what does it cost, is it capped, how long does issuance take?

What does a food truck fire inspection check?

The propane system and the cooking line, primarily: that cylinders are within their DOT requalification date (12 years from manufacture, then on a recurring cycle stamped on the collar), that the LP system, regulators, and connections meet NFPA 58's mobile food facility provisions, that suppression covers the cooking appliances, and that you carry a Class K extinguisher for grease alongside a standard ABC unit. Some jurisdictions want a licensed LP-gas technician's report before the fire marshal's visit. Cadence varies by county: Howard County, Maryland requires annual re-inspection; neighboring Anne Arundel County, Maryland updates its sticker only when the vehicle configuration changes.

Do I need a special permit to sell at a festival or private event?

Yes, in most cases. Your standing mobile permit doesn't carry over to an organized event — those generally run under a separate temporary food establishment or temporary event permit tied to that specific event, often applied for through the organizer rather than directly. Organizers commonly have to notify the health department well in advance, so your deadline is earlier than the event date suggests. Budget the permit fee and, more importantly, the lead time on a certificate of insurance naming the organizer as additional insured — that paperwork is usually the slower of the two.
