Washington permit guide

How to get a coffee cart permit in Washington.

The Mobile Food Business Permit from County Health Department (King County standard, under WA DOH rules) is the foundation. This guide walks the real cost, real timing, and the local pitfalls that trip up first-time Washington operators.

Permit name

Mobile Food Business Permit

Annual cost

$90 to $400 per year

Processing time

4 to 6 weeks

Issuing agency: County Health Department (King County standard, under WA DOH rules).

What this permit covers

Washington licenses coffee carts at the county level under WAC 246-215 and the state Retail Food Code. King County, Pierce County, and Spokane County each run busy programs with their own forms and schedules. The Washington State Department of Health sets the rule framework but does not issue the permit directly.

A Mobile Food Business Permit in Washington covers brewing, steaming, espresso preparation, syrup handling, and on-board cold storage for dairy. The permit is tied to a specific unit, and most counties tie it to a specific approved commissary.

Washington uses risk-based fee tiers. A coffee cart that brews and steams typically lands in the middle tier in King County, which is the most expensive of the major counties. Pierce, Spokane, and Snohomish are generally less.

How much a coffee cart permit costs in Washington

King County Public Health charges annual permit fees of approximately $300 to $400 for a mid-risk mobile coffee operation, plus a one-time plan review fee around $300. Pierce County runs about $200 to $300 per year. Spokane County is closer to $150 to $250.

Plan review approval before the first inspection is the most distinctive Washington requirement. King County will not schedule the inspection until plan review is fully approved.

Commissary cost in Seattle and Bellevue runs $400 to $800 per month. Spokane and Tacoma are less. Washington requires a written commissary agreement at the time of application, and the commissary must be a licensed food establishment.

Add a one-time Food Worker Card requirement for every person handling food. Washington Food Worker Cards are cheap (around $10) but every employee needs one. Add a Certified Food Protection Manager certification ($100 to $200) for at least one person.

Step-by-step: how to apply in Washington

  1. Identify your county

    1 day

    Washington permits at the county level. King, Pierce, Snohomish, Spokane, and Clark counties each have their own forms. Start with the county your commissary is in.

  2. Secure a commissary

    1 to 2 weeks

    Get a signed commissary letter from a licensed food establishment. King County is strict and verifies the commissary against county records.

  3. Submit plan review (mandatory before inspection)

    2 to 4 weeks

    Washington counties, especially King, will not schedule an inspection until plan review is fully approved. Submit menu, layout, equipment list with NSF certifications, tank capacities, sinks, and ventilation. King County plan review can take 3 to 4 weeks during peak season.

  4. Apply for the Mobile Food Business Permit

    5 to 10 days

    Once plan review is approved, submit the permit application with commissary agreement, Food Worker Cards for staff, and Food Protection Manager certificate.

  5. Pass the pre-operational inspection

    Same day, scheduled within 1 to 2 weeks

    A county inspector checks the unit on site against the approved plan. Coffee carts usually pass on the first attempt if equipment matches the plan and tank labeling is correct.

Common pitfalls in Washington

These are the patterns that trip up first-time Washington coffee cart operators. Most are not in the official packet.

King County requires plan review before inspection

This is the most consequential Washington pitfall. King County will not even schedule your inspection until plan review is fully approved. Operators who try to skip ahead lose weeks. Plan submission can also take 3 to 4 weeks of review during peak season.

Food Worker Cards required for every staff member

Washington requires a Food Worker Card for every person handling food. The card is cheap and easy but easy to forget. Inspectors check during operation.

Seattle adds zoning and right-of-way rules

King County issues the health permit. Seattle separately controls where mobile food can operate on city right-of-way through SDOT (Seattle Department of Transportation). Private events are fine. Public-property operations need additional permits.

Commissary must be in your county or adjacent with approval

King County prefers commissaries inside King County. Using a commissary in a neighboring county is possible but adds documentation and may slow approval.

Cities in Washington with additional requirements

Washington permits are issued at varying levels (state, county, or municipal). Each of these cities adds local rules beyond the standard permit.

Seattle (King County)

King County Public Health issues mobile food permits in Seattle. The county is one of the busiest in the country for mobile food and one of the strictest on plan review timing. Seattle SDOT separately regulates right-of-way vending.

Spokane (Spokane County)

Spokane Regional Health District licenses mobile food in Spokane. Fees are lower than King County and plan review is generally faster. Spokane is a strong wedding and corporate event market.

Tacoma (Pierce County)

Tacoma-Pierce County Health Department handles licensing in Tacoma. Pierce County is friendlier on plan review timelines than King County. Tacoma has its own downtown vending rules through the city for public-property events.
