Food Truck Permits & Licenses in Washington: What You Actually Need (2026)

The Evergreen State's Food Truck Scene

Washington State — led by Seattle — has one of the strongest food truck markets in the country. The Pacific Northwest's emphasis on local food, diverse cuisines, and outdoor culture makes it a natural fit for mobile food.

Washington's permitting system is handled primarily at the county level through local health jurisdictions, with the Washington State Department of Health (DOH) setting statewide food safety standards. The process is generally more straightforward than states like California or New York, but Seattle has its own layer of city-specific requirements.

Verify all fees and requirements with your local health jurisdiction and city government. This guide is a starting point, not legal advice.

State-Level Requirements

1. Washington State Business License (UBI Number)

Every business in Washington needs a Unified Business Identifier (UBI) number and state business license:

• Where to apply: Washington State Department of Revenue — apply online through the Business Licensing Service (BLS) portal
• Cost: $90 initial fee (includes Master Business License)
• Renewal: Annual renewal required
• What it covers: State business license, tax registration, and any additional state agency endorsements

2. Washington State Food Worker Card

Washington requires all food workers to obtain a Washington State Food Worker Card from the Department of Health (DOH).

• Cost: $10
• Process: Complete a food safety training course and pass a test — available online through the DOH website
• Timeline: Must be obtained before handling food
• Renewal: Every 2 years (previously 3 years — Washington shortened the renewal period)
• Statewide recognition: Valid across all of Washington State
• Who needs it: Every person who handles, prepares, or serves food

This is one of the most accessible food handler programs in the country — it can be completed in about 2 hours online.

3. Sales Tax

Washington has no state income tax but does have sales tax:

• State sales tax: 6.5%
• Local additions: 1%–4% depending on jurisdiction (total typically 8%–10.5%)
• Prepared food: Taxable in Washington
• Registration: Included in your UBI/business license application
• Filing: Monthly, quarterly, or annually depending on volume — determined by Department of Revenue

4. Business Entity Registration

• LLC: File with the Washington Secretary of State — $200 filing fee online
• Sole Proprietorship: Covered by your Master Business License / UBI registration
• Federal EIN: Free from the IRS

5. County Health Permit (Food Establishment Permit)

Your local health jurisdiction (county health department) issues the food establishment permit for your mobile food unit. Washington has 35 local health jurisdictions — requirements and fees vary, but they all follow the Washington State Food Code (WAC 246-215).

General process:

• Plan review: Submit your truck layout, equipment list, menu, water supply, and waste water system
• Health inspection: Pass a pre-operational inspection before permit issuance
• Annual renewal: With re-inspection
• Fees: Typically $300–$800 annually, varying by jurisdiction and risk category

Important: Washington has a statewide reciprocity system for temporary food events. If you hold a valid food establishment permit from one county, other counties may accept it for temporary events (generally up to 21 days). However, for ongoing regular operation in another county, you typically need that county's permit. Verify reciprocity policies with the specific counties you plan to work in.

City-Specific Requirements

Seattle (King County)

Seattle is the state's largest food truck market and has a well-established permitting framework:

#### King County Health Permit

• Public Health — Seattle & King County issues mobile food unit permits

Commissary costs:

• Seattle area: $500–$1,200/month depending on location and services

Washington's Food Truck-Friendly Features

A few things make Washington particularly good for food truck operators:

• No state income tax — Operators keep more of their earnings (though B&O tax applies in most cities)
• Statewide food worker card — One card works everywhere in the state, unlike states where each county issues its own
• Event reciprocity — The statewide system for temporary events makes it easier to work festivals across counties
• Strong local food culture — Washington consumers actively seek out food trucks, especially at farmers markets and tech campus lunch spots
• Year-round demand in Seattle — Unlike some markets, Seattle's food truck scene stays active through winter (rain gear is more important than season)
