A mobile food commissary kitchen (also called a commissary, central preparation facility, or base of operations) is a licensed, health-department-inspected commercial kitchen that serves as the fixed home base for food trucks, food carts, trailers, and other mobile vendors.
It fills gaps that most mobile units cannot legally or practically handle on their own: bulk food preparation and cooling, overnight refrigerated/dry storage, proper dishwashing (typically a 3-compartment sink), potable water refills, wastewater (greywater) and grease disposal, equipment cleaning, and sometimes overnight parking.
Health departments treat mobile units as extensions of a fixed facility under the FDA Food Code model. Without an approved commissary agreement, most jurisdictions will not issue a mobile food permit.
Why Commissaries Are Required
Mobile units have limited water capacity, refrigeration, and sanitation facilities. They generally cannot:
Cool large batches of food safely.
Perform full warewashing of utensils and equipment after service.
Legally dump wastewater into storm drains or parking lots.
Store TCS (Time/Temperature Control for Safety) foods overnight without commercial refrigeration.
Source potable water or dispose of grease properly on-site.
The commissary provides these services under regulated conditions. Many places require the mobile unit to return to the commissary daily (or after each operating day) for servicing.
Who Needs One
Virtually all food trucks and most food carts that handle unpackaged or TCS foods require a commissary agreement. Requirements are nearly universal across U.S. states and counties, though details vary.
Exceptions are limited:
Fully self-contained units with complete onboard sinks, tanks, refrigeration, and equipment (rare; more common in parts of Texas after recent laws, some Arizona/Florida counties, or limited-prep “Class I” units in places like Oregon/Washington).
Certain pre-packaged-only or low-risk operations.
Specific home-kitchen or food-freedom laws (e.g., limited California MEHKO or Wyoming Food Freedom Act) that generally do not apply to typical mobile retail vending.
Always verify with the local health department, as city/county rules often add stricter requirements than the state.
Typical Services Provided
A proper commissary usually offers some or all of:
Food prep space (stainless tables, cooking equipment as needed).
Commercial refrigeration, freezers, and dry storage (often assigned/locked areas per operator).
3-compartment sink (or commercial dishwasher) for warewashing + separate handwashing sink.
Potable water fill station (backflow-protected).
Wastewater dump station connected to sanitary sewer.
Grease disposal/interceptor.
Restroom access.
Sometimes: mop sink, garbage facilities, overnight truck/cart parking with power, and the signed letter needed for your permit.
The exact services must match what your menu and unit require and be spelled out in the written agreement.
Costs
Costs vary widely by location, services, and usage model:
Type Typical Cost Range Notes
Hourly kitchen access $15–$45/hour (sometimes higher in major cities) Good for part-time or low-volume prep
Monthly membership / shared access $250–$1,200+ Common for regular users; often includes storage
Full-service (prep + storage + water/waste + parking) $500–$1,500+ (can reach $2,000–$3,000 in NYC/SF/LA) Most comprehensive for full-time operators
Limited (storage/dishwashing only) $150–$600 Lower for carts with minimal needs
Additional costs often include a security deposit, required liability insurance (you usually must name the commissary as additional insured), storage fees, and minimum hour commitments. Budget $300–$1,500/month as a realistic planning range for most markets; major coastal metros run higher.
Finding and Choosing a Commissary
Options include purpose-built shared commercial/commissary kitchens, restaurant kitchens rented during off-hours, dedicated food-truck hubs, or catering facilities. Not every shared “ghost” or commercial kitchen qualifies—confirm it can issue a valid commissary agreement accepted by your health department (jurisdiction matching is critical in many places).
Key steps:
1.Contact your local health department for approved lists or requirements.
2.Verify the facility’s current health permit and recent inspection reports.
3.Confirm the agreement covers all needed services and includes required language (parties’ names/addresses, permit numbers, specific services, dates).
4.Check access hours, security, storage allocation, insurance requirements, and cancellation terms.
5.Visit in person if possible.
Resources such as Shared Kitchen Locator and local health department sites help find options in many cities.
Key Compliance Notes
The commissary must generally be in the same jurisdiction (or an approved one) as your operating area.
You typically need food handler and/or manager certifications.
Keep a log of visits/services in many places.
Home kitchens almost never qualify.
Rules differ significantly by state and even by city/county (e.g., strict daily return in much of California and NYC; more flexibility or emerging self-contained options in parts of Texas/Florida).
For a food cart business (especially low-investment concepts like coffee, ice cream, hot dogs, or pre-packaged items), the commissary is often still required but may need fewer services than a full-prep truck, which can lower monthly costs. Check local rules early—before buying equipment—because the agreement is usually mandatory for the health permit.
Regulations and available facilities change, so always confirm current requirements directly with the health authority where you plan to operate.
