Our own crew welds the frame and runs the wiring and plumbing at our Olivehurst, CA shop. On a hot trailer, the crew fits the gas lines too. You can schedule a visit at any stage of your build. We deliver to all 50 states, Roseville included, or you can pick the finished trailer up at the shop.
In Roseville, the trailer's next stop is Placer County Environmental Health. A County specialist inspects it at the Auburn main office or the Tahoe City satellite, depending on location.
Our 3D builder asks for no account and no payment, and you can start over as often as you like. Set the kitchen as hot or cold and pick a length. Then fill the cooking and service sides and add extras like an awning. Designs are kept for 90 days to revisit or share.
Plan the exterior around a Placer County lettering rule. Two sides need the business name in permanent 3-inch letters and the city, state and zip in 1-inch letters. Our in-house wrap team works in 3M vinyl, so that lettering can be part of the artwork.
Our food trailers for sale in Roseville are complete commercial kitchens, each engineered around its menu. Golden State Trailers welds, wires and plumbs every one in Olivehurst, California, before it travels to your site.
Your menu decides the appliances, and the appliances decide the floor plan and the utilities behind it. Our 16 ft food trailer is the shortest of eight lengths, which run up to 30 ft.
Browse our food trailers for sale as starting layouts, or the custom food trailers we have designed for other operators. Caterers can compare our mobile catering trailers. Franchises, schools and corporate food service programs can order three or more units as one project.
Vernon Street Town Square downtown hosts mobile food vendors on second Thursday evenings, March through November. Service runs from 5 to 8 p.m. The City’s free summer Concerts On The Square draw guests early for mobile food before the 8 p.m. show.
The Placer County Fair is held at @The Grounds in Roseville. For a fair, size the refrigeration to hold a full day’s stock at your busiest pace.
Placer County requires every mobile food unit to get local planning approval for public or private property. On private land, the owner’s permission is needed too.
In Roseville, the City’s small business portal points mobile businesses to its Planning Division. Confirm trailer rules there before you order.
Under state law, a fully enclosed trailer you cook in is a special purpose commercial modular. California’s Department of Housing and Community Development, HCD, certifies those units. Placer County issues no health permit to an enclosed unit without the HCD insignia.
HCD’s mobile food facility bulletin lists three approvals: DMV registration, the insignia and final approval by the health official. A new factory-built unit is approved by a third-party agency through design approval and inspections during production.
We work directly with HCD on state certification. Placer County asks operators to contact HCD before they begin the health permit process.
Your health permit comes from Placer County Environmental Health, not the City. The County permits every mobile food facility in Roseville under its classification and permitting requirements.
You submit the County’s application packet, and no inspection is scheduled until it arrives complete. The permit fee is due at the inspection itself.
Placer County files an enclosed unit that fries, grills, boils, slices or chops under Full Prep. Its examples include tacos, burritos and burgers, so a taco food trailer falls in this class.
The County’s Full Prep table lists mechanical refrigeration, hot holding, exhaust ventilation, a three-compartment sink and a handwash sink. Waste water tanks must be 50% larger than potable tanks. Where a three-compartment or prep sink is fitted, the water heater must be able to reach 120°F.
We lay out the kitchen and size the tanks against that table. On our 20 ft spec, 56 gallons of fresh water sit beside a 93-gallon gray tank.
Placer County requires UL 300 fire suppression on exhaust hoods, citing the State Fire Marshal. For other fire safety questions, the County points operators to the local fire department, here the Roseville Fire Department.
Hot builds vent through a UL 710 compliant hood, with the ventilation system conforming to NFPA 96. It runs with 14×14 make-up air, and the 400,000 BTU propane system carries an auto changeover regulator. Our build standards list each system, and the 20 ft spec lists UL 300 suppression.
Nearby Sacramento averages a July high near 94°F, and about 90 days a year hit 90°F or hotter.
A cooking line adds its own heat, and refrigeration must hold temperature through an afternoon service. To counter that, a 15,000 BTU air conditioner sits on the roof of every build we ship. Behind the stainless walls, enhanced insulation is set on reinforced backing.
The air conditioner counts toward the electrical load alongside the kitchen equipment. Coffee and ice cream menus run on a cold trailer, so freezers and refrigeration lead the load plan there.
Once the 3D render of your equipment, windows and workflow has your approval, fabrication begins. Each stage is laid out on our process page.
Nothing leaves Olivehurst untested. Brakes, structure, gas line pressure, electrical load and plumbing all get checked. A hot trailer adds hood airflow and fire suppression.
The handoff covers a walkthrough of each system on board, from water tanks to power. Installed appliances keep the warranties their manufacturers give, and our 1-year bumper-to-bumper coverage protects the trailer itself.
