Napa, CA Food Trucks & Mobile Vendors: Food Truck Permits (2026)

Mobile food service in the City of Napa sits at the intersection of state food law and Napa County health enforcement, with the City layering on business licensing and zoning. The principal food-safety authority is the California Retail Food Code (CalCode), Health & Safety Code §113700 et seq., enforced locally by Napa County Environmental Health (1195 Third Street, Napa). Every food truck or trailer must hold a Mobile Food Facility permit (classified under CalCode based on whether food is prepackaged or prepared on-board), pass an initial plan check, undergo annual recurring inspection, and be tied to a permitted commissary for cleaning, restocking, and waste disposal under Health & Safety Code §114295. Napa County reports approximately 117 mobile food facility permits in active circulation countywide; the Environmental Health permit fee historically runs near $500. Operators must hold a California Food Handler card (HSC §113948) and a Certified Food Protection Manager certificate (HSC §113947.1) for the person in charge. At the City level, operators need a City of Napa Business Tax Certificate under NMC Chapter 5.04 from the Finance Department (minimum $30 for under $12,000 in gross receipts, scaling to 0.1% above); the City also issues a peddler/itinerant permit for sales from a vehicle on a route. Zoning is governed by NMC Title 17: mobile food vending is generally permitted in commercial and industrial zones with the property owner's written consent, restricted on public streets in residential zones, and allowed at special events with a City Special Event Permit. Operating at private-property venues such as Food Truck Fridays requires an event permit even when the venue is private. Sidewalk vending of food on public sidewalks is governed by California SB 946 (the Safe Sidewalk Vending Act, Gov. Code §51036 et seq.), which decriminalized sidewalk vending statewide and prohibits Napa from imposing an outright ban; the City may impose objective time/place/manner restrictions and require sidewalk vendors to hold the same Napa County MFF permit and City Business Tax Certificate. SB 972 (2022) created the Compact Mobile Food Operation (CMFO) category for low-risk sidewalk food carts under CalCode.
