TL;DR
A California concession trailer needs a mobile food facility permit from your county environmental health department, a free CDTFA seller's permit, a local business license, and a fire suppression certification if you cook with open flame. Budget $2,000 to $5,000 in first-year permit and compliance fees, plus a commissary. The full paper path takes 60 to 120 days.
Do you need a license for a concession trailer in California?
Yes. You need a permit before you sell your first taco. Operating a concession trailer in California without one is a misdemeanor under the California Retail Food Code. Every mobile food facility has to hold a valid permit from the local enforcement agency, which is almost always your county environmental health department. That permit comes from California Health and Safety Code Section 114381, which states: "A person proposing to operate a food facility shall obtain a valid permit as specified in this part." [1]
The longer answer is that one permit is never enough. You need several, and they come from three or four different agencies.
Here is the core stack every California concession trailer operator carries:
- County Retail Food Facility (mobile food facility) permit
- California Department of Tax and Fee Administration (CDTFA) seller's permit
- City or county business license
- Fire suppression system certification (required if you run a Type I hood, meaning open-flame cooking like grills, fryers, or woks)
- Vehicle registration as a food facility with the county (separate from DMV trailer registration)
Some counties add a plan review before they issue anything. Los Angeles County Environmental Health, for example, requires a plan check and pre-operational inspection for any new mobile food facility. Confirm the current plan check requirement with your own county. [2]
Operate at a fairground or a weekly farmers market and the venue will usually ask to see your permit before handing you a booth. Certain produce-only vendors at certified farmers markets fall under the California Department of Food and Agriculture, but if you cook, county environmental health is your primary agency. [3]
What are the main permits and which agencies issue them?
The agency you actually file with is local, not state. California splits mobile food oversight between state law and county enforcement. The California Retail Food Code sets the statewide floor. Each county environmental health department enforces it and can add its own requirements on top. [1]
Here is the practical breakdown of permits, who issues them, and roughly what they cost. Fees move every year, so treat these as planning numbers and confirm with the issuing agency:
| Permit | Issuing Agency | Typical Fee Range (CA) |
|---|---|---|
| Mobile food facility permit | County Environmental Health | $200, $800/year [2] |
| Seller's permit | CDTFA (state) | Free [4] |
| Business license | City or county clerk | $50, $250/year |
| Fire suppression inspection/certification | Local fire marshal | $100, $300 |
| Plan check/pre-operational review | County Environmental Health | $100, $500 (one-time) |
The CDTFA seller's permit is free. Anyone selling tangible personal property in California, food included, has to hold one. You apply online at cdtfa.ca.gov. [4]
Los Angeles County charged $541 for a new mobile food facility permit in a recent fee schedule and $384 for renewal, and it updates those numbers annually. [2] San Diego, Sacramento, and the Bay Area counties run in a similar range but they all vary. Pull the current fee schedule from your specific county's environmental health website. Do not trust a number you read anywhere else, including here.
If your trailer has a Type I hood (required for any cooking that produces grease-laden vapors), NFPA 96 governs the suppression system design and certification, and your local fire marshal enforces it. California has adopted NFPA 96 by reference in its fire code. [5]
How much does a concession trailer cost in California?
There are two cost questions here, and mixing them up is how people end up broke by month three. One is what the trailer costs. The other is what the first year of operating it costs in permits and compliance.
Trailer purchases fall into three tiers. A basic used trailer with minimal build-out runs $10,000 to $25,000. A new purpose-built trailer with standard equipment, a Type I hood, and a three-compartment sink runs $30,000 to $60,000. A fully custom large-format trailer with commercial refrigeration, specialty gear, and a generator can pass $80,000. Prices move with materials and demand. Get at least three quotes from builders before you sign.
First-year permit and compliance costs for a California operator look roughly like this:
| Cost Item | Estimated Range |
|---|---|
| County mobile food facility permit | $200, $800 |
| Plan check / pre-operational inspection | $100, $500 |
| CDTFA seller's permit | Free |
| City/county business license | $50, $250 |
| Fire suppression inspection | $100, $300 |
| Food handler cards (per employee, ANSI-accredited course) | $15, $25 each [6] |
| Food safety manager certification (ServSafe or equivalent) | $150, $200 |
| Commercial general liability insurance (minimum recommended) | $1,200, $2,400/year |
| DMV trailer registration | $100, $300 |
Add it up and a realistic first-year compliance budget, before you flip a single burger, is $2,000 to $5,000. That is separate from the trailer purchase. Insurance alone can hit $2,400 for a cooking trailer running propane.
Then there is the commissary. State law requires mobile food facilities to work out of an approved commissary, a licensed commercial kitchen where you prep, clean, and store. Your home kitchen does not count. Commissary rental runs $300 to $800 per month in most California metros, though some operators buy their own space. [1]

How long does getting your permits take in California?
Plan for 60 to 120 days from first application to permit in hand. Some counties run faster. Some run much slower. That range is the honest middle, based on the steps the process actually requires.
Here is where the time goes. Plan check comes first. If your county reviews drawings before it inspects (LA does), you submit specs and wait. LA County's plan check queue has historically taken 4 to 8 weeks depending on workload. Then the pre-operational inspection. Once plan check clears, or if your county skips it, you schedule an inspection, and inspectors are often booked 2 to 4 weeks out. The fire marshal is a separate appointment in a separate queue. The commissary agreement has to be signed before most counties will issue your permit, and finding and signing with a commissary takes 1 to 3 weeks on its own. The CDTFA seller's permit is the one fast step: online applications typically process in 1 to 3 business days. [4]
Plan check is the single biggest time sink in counties that require it.
Buying a used trailer already permitted in California? Ask the seller for the prior permit and inspection history. A trailer with a California permit trail usually gets back into service faster than a fresh build starting from zero.
Do not book events or sign vendor agreements until the permit is in your hand. County inspectors will not move faster because you put a festival on the calendar.
What is the commissary requirement and why does it matter so much?
The commissary rule blindsides more new operators than anything else. California Health and Safety Code Section 114295 requires mobile food facilities to operate from an approved commissary or other approved facility for food storage and preparation, cleaning and sanitizing of equipment and utensils, and vehicle servicing. [1]
In plain English: you cannot prep food at home, you cannot wash equipment in a residential sink, and you cannot park your trailer in a driveway and prep out of it. All of that happens at a licensed commissary.
When you apply for your county permit, the application asks for your commissary agreement. No signed agreement, no permit. And the commissary itself has to be a licensed food facility, meaning it holds its own county permit.
How to find one: search your county environmental health department's database of permitted food facilities, call commercial kitchen rental companies, or look at church kitchens and restaurant incubators that rent time. Los Angeles County's Environmental Health site has a searchable facility database, and San Diego County keeps a similar resource.
Budget commissary access from day one. At $300 to $800 a month, it is often the second or third largest recurring expense after food cost and insurance.
What food handler and food safety certifications does California require?
California requires at least one certified food safety manager on the permit for most mobile food facilities. That person holds a certificate from a program accredited by the American National Standards Institute (ANSI) to the Conference for Food Protection standard, such as ServSafe or the National Registry of Food Safety Professionals. The exam alone costs $30 to $150 depending on provider; the full course-plus-exam bundle runs $150 to $200. Manager certificates are valid for five years. [6]
Every food employee also needs a Food Handler Card within 30 days of hire. California's food handler card law, Health and Safety Code Section 113948, requires the card come from an ANSI-accredited provider. The card costs $15 to $25 and is valid for three years. [6]
None of this is optional. County inspectors check employee food handler cards during routine visits. A missing card is a violation that can trigger a re-inspection fee or, in repeat cases, permit suspension.
Do you need a fire suppression system for a California concession trailer?
If you cook with anything that produces grease-laden vapors, yes. California Fire Code Section 904.12 requires an automatic fire suppression system under any Type I hood. A Type I hood is required over open-flame cooking equipment: fryers, griddles, ranges, woks, charbroilers. NFPA 96, which California has adopted, governs the design, installation, and inspection of those systems. [5]
A Type II hood, for equipment that puts out heat but not grease (a coffee machine or a hot dog roller), needs ventilation but no suppression system.
Once installed, the suppression system has to be inspected by a licensed contractor every six months, and the local fire marshal signs off on the setup before you get your operating permit. Budget $1,500 to $4,000 for initial installation on a new build, then $150 to $300 per semi-annual service visit.
If your trailer only serves prepackaged food, beverages, or items that need no on-site cooking, you may qualify as a limited food preparation facility and skip the Type I hood entirely. Confirm your equipment list with the county before you build out the trailer, not after.
For operators pulling suppression paperwork together before the fire marshal appointment, ConcessionPath's Health and Fire-Suppression Kit ($149 one-time at /start) walks through the specific documents most California counties want at inspection.
How do you register the business entity itself?
Your concession trailer needs a legal business structure before you can open a business bank account, sign a commissary lease, or apply for most permits. Solo operators usually pick one of three: sole proprietorship, LLC, or S-corporation.
Sole proprietorship is the default if you do nothing. No state filing beyond a fictitious business name (DBA) registration with your county clerk, and only if you operate under a name other than your own legal name. California county DBA registrations typically cost $25 to $75 and require a newspaper publication. They create zero liability protection.
An LLC filed with the California Secretary of State costs a $70 filing fee, plus the $800 annual minimum franchise tax to the Franchise Tax Board starting in your second year (year one is exempt under AB 85, effective January 1, 2021). [7] The LLC gives you personal liability protection, which matters when you are running cooking equipment and propane around the public.
File your LLC or corporation at bizfileonline.sos.ca.gov. After filing, get a Federal Employer Identification Number (EIN) from the IRS, free, at irs.gov, and open a dedicated business bank account before you take a dollar of revenue.
With the entity set up, register for your CDTFA seller's permit and, if you have employees, register with the California Employment Development Department for payroll taxes. [4]
What insurance does a California concession trailer need?
California does not set a single minimum insurance amount for mobile food vendors, but nearly every county permit application and event venue in the state wants proof of commercial general liability insurance (CGL) before they let you operate. The standard minimum event organizers and county fairs ask for is $1 million per occurrence and $2 million aggregate.
For a cooking trailer with propane, fryers, or a generator, expect CGL premiums of $1,200 to $2,400 per year. Higher-risk equipment or big-event schedules push that up. Some insurers write food truck and concession policies as a specialty product. Ask specifically for coverage of mobile food operations and product liability.
Hire even one employee and California requires workers' compensation insurance from that first day. There is no employee-count threshold; one person triggers it. [8]
Finance the trailer and your lender will also require commercial property or inland marine coverage on the physical unit. That is separate from your liability policy.
Step-by-step: the full California concession trailer startup sequence
Here is the sequence in the order that actually makes sense, not alphabetical and not the way a government website lists it.
1. Decide on your menu and equipment list. Your hood type, suppression requirement, and permit tier all follow from what you cook. Lock the menu before you spend a dollar on the build.
2. Form your business entity with the California Secretary of State and get your EIN from the IRS. Do this before signing any lease or commissary agreement.
3. Register for a CDTFA seller's permit online. Free and fast. [4]
4. Get a fictitious business name (DBA) from your county clerk if you operate under a trade name.
5. Find and sign a commissary agreement. Call county environmental health first and ask for their list of approved commissaries, or search the county's permitted facility database.
6. Submit your mobile food facility permit application and, if required, your plan check documents to county environmental health. Attach the commissary agreement, your menu, equipment list, and trailer specs.
7. Schedule and pass the fire marshal inspection for your suppression system (if applicable).
8. Pass the county pre-operational inspection.
9. Receive your county mobile food facility permit. That is your green light.
10. Get your city or county business license from the local clerk.
11. Get food handler cards for all employees and your food safety manager certification if you do not already hold one.
12. Get commercial liability insurance and, with employees, workers' compensation coverage.
13. Register your trailer with the DMV if it is newly purchased and title has not transferred.
Do not skip step 5 and jump to step 6. County applications get rejected or stalled constantly because operators submit without a commissary agreement.

County-by-county differences: what changes depending on where you operate?
California has 58 counties, and each one can stack requirements on top of the state floor. A few differences that actually change your paperwork:
Los Angeles County requires a plan check for new mobile food facilities and runs a two-tier permit structure that splits limited food prep (no cooking from raw) from full food prep. LA County Environmental Health also keeps a searchable database of approved commissaries. Its fees are among the highest in the state. [2]
San Diego County runs a similar plan check process and publishes its mobile food facility fee schedule every year. San Diego also enforces the commissary requirement hard and runs spot checks.
Orange County Environmental Health Division permits mobile food facilities through an application close to LA's but with different fee tiers. Confirm directly with OC Environmental Health.
Rural counties like Siskiyou, Modoc, and Trinity usually have smaller inspection backlogs and lower fees. They also have far fewer commissary options, which is often the bigger problem for an operator up there.
Operate in multiple counties and you generally need a separate permit for each one where you work regularly. Some counties have reciprocity; many do not. Ask your home county whether any arrangement exists with neighbors before you assume an LA County permit covers you in Ventura.
One more thing that trips people up: city and county fire departments sometimes hold separate jurisdictions inside the same county. In unincorporated areas, the county fire marshal handles suppression inspections. Inside city limits, the city fire department may. Confirm jurisdiction before you book the inspection.
What ongoing compliance does California require after you open?
Permits in California are annual and have to be renewed before they expire. Miss the renewal and you typically eat a late fee, and some counties make you re-inspect before reinstatement. Set a calendar reminder 60 days ahead of your permit anniversary.
County environmental health runs unannounced inspections of mobile food facilities, usually one to three times a year depending on the county's risk-based schedule. Results are posted publicly in most California counties. A posted grade or score matters for customer trust and for your venue relationships.
Fire suppression systems need a licensed contractor service every six months, and you keep the service tag and inspection report in the trailer for the fire marshal. [5]
Food handler cards expire every three years. Manager certifications expire every five. Track both, for yourself and every employee.
The CDTFA seller's permit never expires, but you have to file sales tax returns on the schedule CDTFA assigns you, monthly, quarterly, or annually depending on sales volume. Miss a filing and penalties post automatically. [4]
Grow your revenue and add staff, and California's employment rules arrive fast: minimum wage that varies by city, mandatory sick leave, workers' comp, and payroll registration with EDD. California's statewide minimum wage is $16 per hour as of January 1, 2024, with some cities and counties higher. [9]

Frequently asked questions
Do you need a license for a concession trailer in California?
Yes. California Health and Safety Code Section 114381 requires a valid permit from your county environmental health department before you operate any mobile food facility. You also need a CDTFA seller's permit, a local business license, and a fire suppression certification if you cook with open flame. Operating without a county permit is a misdemeanor. Confirm current requirements with your specific county's environmental health department.
How much does it cost to start a concession trailer in California?
A new purpose-built concession trailer costs $30,000 to $60,000. First-year permits and compliance fees run $2,000 to $5,000, including the county mobile food facility permit ($200, $800), plan check, business license, fire inspection, food safety certifications, and commercial liability insurance. Commissary rental adds $300 to $800 per month. Total first-year cash outlay before food cost commonly passes $35,000 for a new build.
How long does it take to get a concession trailer permit in California?
Realistically 60 to 120 days from first application to permit in hand. The biggest delays are plan check queues (4 to 8 weeks in large counties like LA) and scheduling inspections. A CDTFA seller's permit processes in 1 to 3 business days. Do not book events or sign vendor agreements before your county permit is issued; inspectors will not expedite for external deadlines.
Does a California concession trailer need a commissary?
Yes. California Health and Safety Code Section 114295 requires mobile food facilities to operate from an approved commissary for food prep, equipment cleaning, and vehicle servicing. You cannot use a residential kitchen. The commissary must hold its own county food facility permit. You need a signed commissary agreement before your county will issue your mobile food facility permit. Commissary rental runs $300 to $800 per month in most California metro areas.
Do California concession trailers need fire suppression systems?
Yes, if you cook with equipment that produces grease-laden vapors: fryers, grills, griddles, charbroilers, or woks. California adopted NFPA 96, which requires an automatic suppression system under any Type I hood. Installation costs $1,500 to $4,000 on a new build. The system must be inspected every six months by a licensed contractor. Trailers serving only prepackaged food may not need a Type I hood; confirm your equipment list with the county.
What food safety certification does California require for a concession trailer?
California requires at least one certified food safety manager per permitted facility. The certificate must come from an ANSI-accredited program such as ServSafe or the National Registry of Food Safety Professionals. The course-plus-exam bundle runs $150 to $200 and is valid for five years. Every food employee must also have a Food Handler Card from an ANSI-accredited provider within 30 days of hire. Cards cost $15 to $25 and are valid for three years.
Do you need a seller's permit to run a concession trailer in California?
Yes. A CDTFA seller's permit is required for anyone selling tangible personal property, including food, in California. The permit is free and you apply online at cdtfa.ca.gov. It typically processes in 1 to 3 business days. Once you have it, you are responsible for filing sales tax returns on whatever schedule CDTFA assigns based on your sales volume. Missing a filing generates automatic penalties.
Can you operate a concession trailer in multiple California counties?
Generally you need a separate permit for each county where you operate regularly. Some counties have reciprocity agreements with neighboring counties but many do not. Ask your home county environmental health department whether any reciprocity applies before you assume coverage. City fire departments and county fire departments may also have separate suppression inspection jurisdictions within the same county, so confirm before operating in a new city.
What business entity should a California concession trailer operator form?
An LLC is the most common choice for solo operators because it provides personal liability protection and is reasonably simple to maintain. A California LLC costs $70 to file with the Secretary of State plus an $800 annual franchise tax starting in year two (year one is exempt under AB 85). A sole proprietorship costs almost nothing but gives you no liability protection, which matters when you operate cooking equipment and propane in public spaces.
What insurance does a California concession trailer need?
Commercial general liability insurance is required by most event venues and county permit applications. The standard minimum is $1 million per occurrence and $2 million aggregate. Premiums for a cooking trailer run $1,200 to $2,400 per year. California law requires workers' compensation insurance from day one if you have even one employee. If you finance the trailer, your lender will require commercial property or inland marine coverage on the physical unit.
How often do California concession trailers get inspected?
County environmental health inspects mobile food facilities one to three times per year on a risk-based schedule. Inspections are typically unannounced. Results are posted publicly in most California counties. Fire suppression systems require a licensed contractor service visit every six months, with the service tag kept in the trailer. Missing either type of inspection can result in a re-inspection fee or, for serious violations, a permit suspension.
How much is a California mobile food facility permit?
Fees vary by county and are updated annually. Los Angeles County's new permit fee was $541 in a recent fee schedule; renewal was $384. Other large counties run in a similar range. Plan check fees, if required, add $100 to $500 as a one-time cost. Confirm the current fee with your specific county environmental health department before budgeting, as these figures change with each fiscal year.
Does California require a plan check for a new concession trailer?
Los Angeles County requires a plan check for new mobile food facilities, and several other large counties do too. The plan check involves submitting trailer drawings, your equipment list, and commissary information for review before an inspection is scheduled. Plan check queues in LA County have historically run 4 to 8 weeks. Check with your specific county environmental health department whether a plan check is required; smaller counties sometimes waive it.
What is the California minimum wage for concession trailer employees in 2024?
California's statewide minimum wage is $16 per hour as of January 1, 2024. Several cities and counties set higher local minimums, including Los Angeles, San Francisco, and San Diego. Fast food workers in California are subject to a separate $20 per hour minimum under AB 1228 effective April 2024. Concession trailer operators with employees must also provide mandatory paid sick leave and register with the California Employment Development Department for payroll taxes.
