A shop knows where its customers are because they come to it. A truck goes to them, and every place it parks sits under some health department’s rules. Those rules decide which cities your ads, your profile’s service area and your booking page can honestly offer, and they differ more than most owners expect.
Los Angeles County. A mobile food facility has to operate out of a commissary, a mobile support unit or another approved facility, and the county will not issue a permit until the commissary location is verified. Trucks file a route sheet listing the address, phone number and arrival and departure times of every stop, and the county accepts a post on Facebook, Instagram, Yelp or similar as an approved way to submit it. Every approved truck should carry a letter grade. Long Beach, Pasadena and Vernon run their own health departments, so a county permit is not the whole map.
Oregon. The Oregon Health Authority does not require a commissary if the unit can show it is self-sufficient, and the state sorts units into four classes, with Class IV allowed a full menu. In Multnomah County, which covers Portland, carts must stay on wheels, most need a commissary unless they have a three-compartment sink, and licenses run by calendar year.
Texas. The legislature passed House Bill 2844 on May 26, 2025. Since July 1, 2026, one license from the Department of State Health Services replaces the separate license each local health department used to issue, and it expires a year from the pre-licensing inspection. Austin still lists its own forms, including a central preparation facility contract and a restroom facility agreement.
Where you may stop. In the Institute for Justice’s 2012 survey of the 50 largest cities, 20 kept trucks a set distance from brick-and-mortar competitors and 34 closed off parts of the city. Treat that as history, not current law, but expect a version of it wherever you go.
What this means for marketing is simple. Google lets a service-area profile list up to 20 cities or postal codes within about two hours’ drive of the base. List the places you are permitted to serve, not every town in range. Point ads only at cities where you can legally park or cater, and put the permit and insurance proof on the booking page, because the people booking you are checking the same things the inspector does.
