Food Truck Requirements in California: Permits and Health Code

Opening a food truck in California means clearing approvals from several agencies before your service window opens. At the state level, food truck requirements in California include a seller’s permit from the California Department of Tax and Fee Administration, a construction insignia from the Department of Housing and Community Development, food safety certifications, and a commissary arrangement. Local governments then layer on a health permit under the California Retail Food Code, a business license, fire inspection, vehicle identification rules, and insurance demands. The pieces have to fit together in a particular order, and skipping any of them can stop your launch.

Seller’s Permit and Local Business License

Every operator selling tangible goods in California needs a seller’s permit from the California Department of Tax and Fee Administration. Revenue and Taxation Code § 6066 requires an application for each place of business.¹ The permit is free, though the CDTFA may require a security deposit if you have a history of nonpayment or a previously revoked permit.² It’s the authority to collect and remit sales tax, and it’s the tax ID most other agencies will ask to see.

You also need a business license from the city or county where you primarily operate. Whether it comes from a city clerk or a county office depends on whether your base sits in an incorporated city or an unincorporated area.³ Fees vary and are often tied to expected gross receipts. Operating across multiple cities can mean separate licenses for each one.

HCD Insignia and Truck Construction

Before any local health department will issue you an operating permit, the truck’s construction has to be certified by the California Department of Housing and Community Development. HCD inspects the electrical, plumbing, heat-producing, and fire and life safety systems, then affixes an insignia sticker confirming the vehicle meets state building codes.⁴ Title 25 of the California Code of Regulations governs how the insignia is issued and administered.⁵

If your truck was built without an insignia or you’re converting a vehicle, you’ll submit form HCD MH 415 and pay an insignia fee of $51 to $83, plus a minimum one-hour inspection fee of $238. Additional hours are $109 each.⁴ Violations found on inspection have to be corrected, and reinspection costs more. If you’re buying used, verify a valid HCD insignia before you sign; retrofitting a non-compliant vehicle can cost more than the truck.

Health Permit Under the California Retail Food Code

The California Retail Food Code, at Health and Safety Code § 113700, sets the statewide floor for food safety in every food facility, mobile ones included.⁶ No food facility can operate without a valid permit from the local enforcement agency, and permits are only issued after the agency confirms the facility and its methods meet code.⁷

Operating without the required permits exposes you to immediate closure and a penalty of up to three times the cost of the permit, on top of any other enforcement the local agency pursues.⁸ Inspectors can impound food, equipment, or utensils they believe are contaminated or noncompliant. Unannounced inspections are routine, and failed inspections are public record.

Food Safety Certifications

Certified Food Protection Manager

Every food truck that handles nonprepackaged, potentially hazardous food must have at least one owner or employee who has passed an accredited food safety certification exam. Accredited providers include ServSafe and the National Registry of Food Safety Professionals. The certified person doesn’t have to be on the truck every hour, but the certificate has to be kept on file and produced on demand.⁹ Recertification is required every five years. If ownership changes or your only certified person leaves, you have 60 days to certify someone new before facing violations.

California Food Handler Card

Every other employee who prepares, stores, or serves food must obtain a California Food Handler Card within 30 days of hire. The card requires a training course and an assessment covering safe food handling basics. Cards are valid for three years from issuance, regardless of whether the employee changes jobs.¹⁰ Violating the food safety certification requirements is an infraction punishable by a fine of up to $100 per day of operation out of compliance.⁹

Commissary Agreement

California law requires every mobile food facility to operate from a licensed commissary, mobile support unit, or other facility approved by the local enforcement agency.¹¹ You cannot use your home kitchen, garage, or driveway. The commissary is the hub for tasks you can’t safely or legally perform on the truck: restocking potable water, disposing of wastewater, cleaning equipment, and overnight food storage.

The daily return catches new operators off guard. Your truck must return to the commissary or another approved facility at least once every operating day for cleaning and servicing. Potentially hazardous food held at or above 135°F on the truck has to be destroyed at the end of each operating day rather than carried over.¹¹ When the truck isn’t in use, it must be stored at the commissary or another approved location protected from contamination. Inspectors check your written agreement, so keep it current and on hand.

Onboard Equipment and Sanitation

The Retail Food Code sets equipment standards that scale to the type of preparation you do. Trucks approved for limited preparation, like prepackaged items or scooping ice cream, face lighter requirements than trucks doing full cooking on board.

For trucks handling nonprepackaged food, the equipment list includes:

A dedicated handwashing sink at least 9 by 9 inches and 5 inches deep, separate from the warewashing sink. If the two sinks sit less than 24 inches apart, a 6-inch metal splash guard has to separate them.
A water heater capable of at least 120°F for full-prep trucks or 100°F for handwashing-only trucks, with a minimum capacity of 3 gallons for full-prep and half a gallon for limited-prep. It must run independently of the vehicle engine.
Wastewater handling where any equipment prone to spillage has a drip tray draining into a waste tank. No liquid waste can drain onto a street, sidewalk, or the ground.

These come from the mobile food facilities chapter of the Health and Safety Code.¹¹ During your permit inspection, the health official tests water temperatures, checks refrigeration, and verifies that the actual build matches the floor plans you submitted.

Fire Safety and Propane

Local fire marshals conduct a separate inspection of the truck’s fire suppression systems. Mobile cooking operations must be protected by an automatic hood suppression system, and a Class K fire extinguisher is required when the truck has deep fat fryers or other equipment producing grease-laden vapors.¹² Hood suppression systems require professional service at least every six months; portable extinguishers require annual service. Keep service records on the truck. An expired certification can hold up your permit the same as a missing extinguisher.

Propane tanks add their own rules. Tanks have to be mounted on the outside of the vehicle or inside a vented cabinet that is vaportight to the interior. The cabinet must be labeled “LP-Gas only” in letters at least one inch high. Tanks must be fastened to withstand a static load of four times the filled weight of the container, and the main shutoff valve must be reachable without tools. Field welding on propane cylinders is prohibited.

Vehicle Identification and DMV Registration

California requires every mobile food facility to display the business or operator name, city, state, and ZIP code on the customer-facing side of the truck. The business name has to appear in letters at least 3 inches tall in a color that contrasts with the vehicle exterior; the city, state, and ZIP code must be at least 1 inch tall. Motorized trucks need this identification on two sides.¹¹

On the DMV side, commercial motor vehicles with a gross vehicle weight of 10,001 pounds or more must be registered as commercial vehicles. Owners of vehicles with an unladen weight between 6,001 and 10,000 pounds declare a maximum operating weight. Vehicles over 10,001 pounds are assessed under the Commercial Vehicle Registration Act rather than standard weight fees.¹³ Diesel trucks with a manufacturer GVWR over 14,000 pounds must also comply with the California Air Resources Board’s Truck and Bus Regulation.

Insurance

California doesn’t impose a single statewide insurance mandate specific to food trucks, but proof of coverage comes up almost everywhere. Local health permit applications, commissary agreements, event organizers, and private property contracts commonly require general liability at $1 million per occurrence, and some contracts require $2 million in aggregate.

The practical minimum for most operators:

Commercial auto insurance covering the vehicle, permanently attached equipment like fryers and refrigeration, and liability during transit.
General liability insurance for third-party injury or property damage claims, including customer illness from contaminated food.
Workers’ compensation, required under California law when you have employees and enforced by the Department of Industrial Relations. Operating without coverage when required brings significant penalties.

Shop insurance before you finish building. Some carriers won’t cover certain cooking methods or equipment configurations, and finding out mid-buildout is expensive.

If You Hire Employees

Once you hire, federal and state payroll obligations apply. You’ll need a federal Employer Identification Number from the IRS. The application is free and completed online; your legal entity must already be formed with the state, and the online tool runs during limited hours.¹⁴ Quarterly payroll filings on IRS Form 941 report income tax withheld along with Social Security and Medicare taxes; tips of $20 or more per month are subject to Social Security and Medicare as well.¹⁵ California adds state unemployment insurance and employment training tax through the Employment Development Department. Missed quarterly deadlines trigger penalties and interest that accumulate quickly.

Putting the Application Together

With the underlying pieces in place, the final step is submitting your application to the local environmental health department. A complete package usually includes HCD insignia documentation, a signed commissary agreement, your proposed menu, vehicle floor plans, proof of food safety certifications, and the applicable fee. Some counties accept online submissions; others require in-person filing.

Once paperwork clears, the department schedules a physical inspection of the truck. The inspector verifies the build matches the submitted plans, tests water temperatures and refrigeration, and checks sanitation features. If the truck passes, the department issues a permit sticker that must be displayed in a prominent, visible location on the vehicle.¹¹ Fees and processing times vary by county, so contact your local environmental health office early to understand both cost and timeline before you commit to a launch date. Permits renew annually, and unannounced follow-up inspections continue throughout the year.
