How to Start a Food Truck in Washington State (2026)

How to Start a Food Truck in Washington State (2026)

Three structural facts shape food truck operations in Washington and they trip up first-time operators coming from California, Texas, or Florida. First, Washington has 35 local health jurisdictions, not a single state-issued food truck permit – your home county (King, Pierce, Spokane, Snohomish, Clark, etc.) issues your primary permit, and statewide reciprocity only covers short-duration events. Second, WAC 246-215 mandates a commissary: every mobile food unit must be tied to a permitted commercial kitchen for daily return, cleaning, food storage, and water/wastewater servicing – your home kitchen is not eligible, period. Third, if you vend in Seattle, you need four separate permits stacked: a Seattle Business License Tax Certificate, a Public Health-Seattle & King County mobile food unit permit, a Seattle Fire Marshal propane permit, and a Seattle SDOT Street Use Mobile Food Vending Permit – and the Seattle vending year runs February 1 to January 31, with November 30 deadlines to keep location priority.

The opportunity is still real. Seattle’s lunch-truck pod culture (especially the South Lake Union and downtown rotations serving Amazon, Microsoft, and other tech employers), Tacoma’s growing food scene, and Spokane and Tri-Cities low-cost markets all support viable food trucks. But because Washington taxes food truck sales as full retail (state 6.5% + local up to 4.1%) and L&I workers’ comp must come from the state fund, the WA food truck has higher fixed costs than a comparable truck in OR (no sales tax) or NV (lower payroll burden).

How to Start a Food Truck in Washington (Step by Step)

Step 1: Form Your LLC and Get Your UBI

File a Certificate of Formation with the Secretary of State CCFS portal: $200 online or $180 paper. $70 annual report. Get a free EIN. File the DOR Business License Application ($90) for your UBI. Add a Seattle endorsement, Tacoma endorsement, Spokane endorsement, or other city endorsement for each city where you’ll regularly vend.

Step 2: Find and Contract a Commissary

Washington’s WAC 246-215 Retail Food Code Part 9 requires every mobile food unit to operate out of a permitted commissary. The commissary handles:

  • Daily return for cleaning the truck and equipment
  • Food storage – your truck cannot be the primary cold/dry storage
  • Food prep that exceeds the truck’s safe capacity (most prep happens at the commissary)
  • Potable water fill and gray-water dump
  • Restocking supplies

Your home kitchen does not qualify. Permitted commissaries include commercial kitchens, restaurants willing to host food trucks, shared commercial kitchens (Common Kitchen Seattle, Hood Famous Café, Spice Bridge Tukwila, and many others), and cottage food production facilities that have a commercial-kitchen designation. Get a written commissary agreement with the permitted facility’s name, permit number, hours of access, and services included. The commissary agreement is required as part of your Mobile Food Unit Plan Review submission.

Typical commissary fees run $300-$1,500/month depending on amenities, location, and how heavily you use the kitchen for prep.

Step 3: Submit Mobile Food Unit Plan Review to Your County

Each of Washington’s 35 local health jurisdictions handles food truck permitting in its territory. Identify your home health jurisdiction (typically your county) and submit plan review BEFORE you build out the truck or buy a finished truck:

Plan review submission package: truck floor plan with equipment placement, equipment list with NSF certifications, menu with all foods you plan to serve, water tank capacity (potable and gray water), wastewater disposal plan, fire suppression details (Type 1 hood with ANSUL system if cooking with grease), commissary agreement, and a copy of your commissary’s food permit. Plan review fee runs roughly $200-$600 depending on jurisdiction. After approval, your truck is built or modified to plan, then a final inspection at the commissary or county health office.

Step 4: Get Your Annual Mobile Food Service Permit

After final inspection, your county health jurisdiction issues an annual permit. Examples:

  • King County: $400-$1,200/year depending on risk class; permit year runs April 1 – March 31; 2026 fee schedule
  • Pierce County: Comparable fee structure under Tacoma-Pierce County Health
  • Spokane Regional Health District: Lower fees than King County typical

Risk class is set by what you serve. Higher-risk food handling (raw meat cooking, refrigeration of TCS-time/temperature-controlled-for-safety foods, complex prep) gets higher fees. Coffee, tea, prepackaged snacks, and similar low-risk operations get lower fees.

Reciprocity for events: Washington has limited statewide reciprocity for temporary food events – your home-county permit may be honored for short events (typically up to 21 days) in another county. Each event still requires registration with the host county’s health department. Check before assuming your King County permit covers a Spokane festival.

Step 5: Get Food Worker Cards for Every Food Worker

Every employee on a Washington food truck handling unpackaged food, food-contact surfaces, or utensils must hold a Washington State Food Worker Card:

  • Cost: $10 per card
  • Online training: ~1 hour at foodworkercard.wa.gov – the only authorized online program statewide
  • Initial card valid 2 years
  • Renewal card valid 3 years standard, or 5 years if you complete 4+ hours of approved additional food safety training
  • Person-in-Charge (PIC): A designated PIC with a current Food Worker Card must be on duty at all times the truck is operating

Step 6: Seattle’s Layered Permit Stack (If Operating in Seattle)

If you vend within Seattle city limits, you need four permits stacked on top of state and county:

1. Seattle Business License Tax Certificate

Seattle’s city-level business license, required if you have a Seattle physical location, employees, or generate $2,000+ in annual gross receipts in Seattle. Includes Seattle B&O on top of state B&O.

2. Public Health-Seattle & King County Mobile Food Unit Permit

Same county permit as Step 4 above – this is your Seattle health permit too.

3. Seattle Fire Marshal Permit (Propane Cooking)

Required if you cook with propane (almost every food truck). Annual fee, separate inspection. Seattle Fire Department contact through the Seattle Services Portal.

4. Seattle Street Use Mobile Food Vending Permit (SDOT)

Required to vend in the public right-of-way (sidewalks, curb space, public plazas). Apply through the Seattle Services Portal. Permit valid up to one year. Vending year runs February 1 – January 31; missing the November 30 deadline forfeits priority for your location. Required documents: site plans (3 sets) with truck dimensions, copies of Seattle Business License + Health + Fire permits, menu, photo of truck, hours/days proposed, and $1 million Commercial General Liability insurance with City of Seattle named as additional insured. Approval timeline ~8 weeks.

Step 7: Sales Tax, B&O, and the WA Payroll Stack

Food truck revenue is taxed at full retail:

  • Retailing B&O: 0.471% on gross sales
  • Retail sales tax: Destination-based (charge the rate at your truck’s location at time of sale). Seattle ~10.35%, Bellevue ~10.3%, Tacoma ~10.3%, Spokane ~9.0%, Olympia ~9.5%, Vancouver ~8.7%. Use the DOR rate lookup
  • Food and beverage exemption: Generally not applicable to food trucks – prepared foods sold for immediate consumption are NOT exempt from sales tax. (Cold packaged groceries from a grocery store are exempt; hot/prepared restaurant-style food is not.)

If you employ workers:

  • UI through ESD: $78,200 wage base 2026; new employer ~1.0% varies by industry rating
  • PFML: 1.13% in 2026 (employee up to 71.43%; employer share 28.57% if 50+ employees)
  • WA Cares: 0.58% withheld from employee wages, no employer share
  • Workers’ comp: L&I state fund (private illegal). Risk class 3905 (Restaurants) typical for food trucks; rate varies by experience.
  • Minimum wage: $17.13 statewide; $21.30 Seattle (no small/large split as of 2026); SeaTac, Tukwila, Renton, Bellingham, Everett, Burien, and unincorporated King County also higher than state.
  • Seattle PSST + Secure Scheduling: Apply to food truck workers in Seattle – earned at 1 hour per 30 (PSST), and Secure Scheduling rules around posted schedules and “predictability pay” for last-minute changes.

Washington Food Truck Market: Where the Lunches Are

The Puget Sound corridor anchors most WA food truck revenue, but each metro has a distinct rhythm:

  • Seattle (Downtown, South Lake Union, Capitol Hill, Ballard): Tech-employer lunch traffic Mon-Fri. Amazon’s South Lake Union campus, Microsoft’s downtown offices, F5 Networks, Expedia, Tableau, and many others rotate truck pods. Premium pricing $14-$22 per entrée. Dinner pods at Capitol Hill and Pioneer Square. Permit stack heaviest of any WA market.
  • Eastside (Bellevue, Redmond, Kirkland): Microsoft, Meta, Google campuses. Strong lunch demand; lower permit overhead than Seattle. Many trucks rotate from Seattle.
  • Tacoma: Growing food truck scene around UW Tacoma, Hilltop, the Foss Waterway, and JBLM. Lower fees, strong weekend events.
  • Spokane: Festival circuit (Pig Out in the Park, Skyfest, Bloomsday). Lower regulatory cost, smaller daily revenue ceiling.
  • Tri-Cities (Richland-Pasco-Kennewick): Hanford federal contractor lunch demand, growing wine-region food scene.
  • Bellingham: WWU students + cross-border Canadian shoppers + Saturday markets.
  • Vancouver, WA: Portland-adjacent. Cross-border food truck operators sometimes maintain dual permits in Vancouver and across the river in Portland.

Frequently Asked Questions

Do I need a state-level food truck license in Washington?

No – Washington has 35 local health jurisdictions, not a single statewide food truck permit. Your home county (King, Pierce, Spokane, Snohomish, Clark, etc.) issues your primary Mobile Food Service Permit under the statewide Retail Food Code (WAC 246-215). The Washington State Department of Health (DOH) sets statewide standards but doesn’t issue permits directly. Statewide reciprocity covers some short-duration temporary events (typically up to 21 days) in other counties, but each event still requires registration with the host county.

Can I operate a food truck from my home kitchen in Washington?

No. Washington’s WAC 246-215 mandates that every mobile food unit operate from a permitted commercial commissary – your home kitchen does not qualify. The commissary handles daily return for cleaning, food storage, prep that exceeds the truck’s capacity, potable water fill, gray-water dump, and supply restocking. Get a written commissary agreement with a permitted commercial kitchen, restaurant, or shared commissary kitchen before submitting your plan review. Typical commissary fees run $300-$1,500/month.

How much does a Washington Food Worker Card cost?

The $10 Washington State Food Worker Card is required for everyone handling unpackaged food, food-contact surfaces, or utensils on a food truck. Take the online training and exam at foodworkercard.wa.gov – the only authorized statewide online program. Initial card is valid 2 years. Renewal is valid 3 years standard, or 5 years if you complete 4+ hours of additional approved food safety training.

What permits do I need to operate a food truck in Seattle?

Four permits stacked: (1) Seattle Business License Tax Certificate (city-level business license), (2) Public Health-Seattle & King County Mobile Food Unit Permit (~$500-$1,200/year), (3) Seattle Fire Marshal permit (if cooking with propane), and (4) Seattle SDOT Street Use Mobile Food Vending Permit for the public right-of-way. The SDOT permit requires $1M Commercial General Liability with the City of Seattle named as additional insured. The Seattle vending year runs February 1 – January 31, with applications due by November 30 for next-year priority. Approval timeline ~8 weeks.

How much does a King County food truck permit cost?

King County (Public Health-Seattle & King County) Mobile Food Service permits run $400-$1,200/year depending on risk class. The permit year is April 1 through March 31. Add a $200-$600 plan review fee in the first year. Higher-risk operations (raw meat cooking, complex TCS food prep) pay higher fees than low-risk (coffee, packaged snacks).

Are food truck sales subject to sales tax in Washington?

Yes. Food truck sales of prepared food and beverages are subject to Retailing B&O at 0.471% AND retail sales tax at the destination rate (state 6.5% + local). Combined rates run from ~7.0% in low-tax jurisdictions to 10.35% in Seattle and 10.3-10.4% in much of King County. Tax is destination-based: charge the rate at the truck’s location at time of sale. The grocery food exemption does NOT apply to prepared foods sold for immediate consumption.

Is workers’ comp required for a Washington food truck?

Yes if you have W-2 employees. Workers’ comp must come from the L&I monopolistic state fund – private workers’ comp is illegal in Washington. Restaurant risk class 3905 typically applies. Sole proprietors and single-member LLC owners with no employees are exempt but may opt in. Premiums are calculated per worker hour by risk class and your experience-rated factor (after about three years of claims history).
