Your County Environmental Health Department
California regulates mobile food facilities primarily at the county level under the California Retail Food Code (CalCode), not through a single state permit. Requirements, fees, and inspection frequency vary by county — start with the environmental health department for the county you'll operate in.
CDPH Retail Food Program →The order matters — several of these are expensive to do out of sequence.
CalCode is statewide, but the permit, the fee schedule, and the inspector all belong to a county environmental health department. Which county you base in changes what you pay and how often you are inspected, so decide that before you commit to a build.
CalCode requires a mobile food facility to operate from an approved commissary, and counties will not issue the permit until that location is verified. A signed commissary agreement is part of the application, not a follow-up item.
A new build, a remodel, or a significant change to equipment, menu, or operation triggers plan check. Expect to submit the truck layout, an equipment list, the menu, water system specifications, and the commissary agreement.
Counties charge plan check as its own fee on top of the annual health permit. Published county rates run into the hundreds of dollars for plan check alone, and the annual permit is separate again.
The inspector verifies the built unit against the approved plans, then issues the permit. Only after that can the truck legally serve.
California is the most expensive of the six states covered here, and the spread between counties is wide. Los Angeles County's published guidance puts combined plan check and permit costs in the high hundreds to around a thousand dollars a year; other counties charge plan check alone in the $400–$970 range depending on facility type. Treat any figure you read as a starting point and get the current schedule from the county you are actually applying in.
Your county environmental health department both permits and inspects. There is no reciprocity built into CalCode — a permit from one county does not entitle you to trade in the next one, and counties that share a metro boundary each run their own process. Operators working across a county line generally end up permitted in both.
Generally yes. CalCode is a statewide code but permits are issued county by county, and there is no statewide reciprocity. If you regularly cross a county line to trade, expect to hold a permit on both sides.
No. CalCode requires a mobile food facility to operate in conjunction with an approved commissary, and the county will not issue a permit until it has verified the commissary location. Onboard tanks do not remove the requirement.
A new mobile food facility, a remodel, or a significant change to equipment, menu, or operations. Changing your menu enough to need different equipment can put you back through plan check even on an already permitted truck.
California food truck rules and regulations live in the California Retail Food Code (CalCode), but enforcement is county by county through environmental health departments, so requirements and fees shift at every county line. The permit steps above cover the sequence; your county's environmental health office has the binding local version.
