King County health permit plus Seattle street/use checksSources last checked 2026-07-06

Quick answer

Seattle operators should treat the current status as King County health permit plus Seattle street/use checks. Before building, filing, or vending, confirm your menu, vehicle, commissary, fire setup, tax records, and first location with King County Public Health, Seattle OED, SDOT, and Seattle Fire.

Cost, renewal, and tax notes

Cost

Budget for King County plan review/permit, Seattle street-use or location fees, fire inspection, commissary, and business-license costs.

Renewal

Track King County permit renewal, Seattle street-use or location permits, fire inspection records, and plan changes.

Tax

Keep Washington business license, sales tax, and location/event sales records by vending site.

Location, commissary, and fire notes

Seattle requirements differ for public streets, sidewalks, plazas, private property, curb spaces, stadium/event areas, and temporary vending.

King County mobile food businesses need plan review and approved servicing, food source, water, wastewater, and storage practices.

Seattle participates in regional food truck fire inspection recognition, but vendors should keep proof of current inspection with the truck file.

Documents to gather

  • King County mobile food business permit materials
  • Menu and plan review documents
  • Seattle street-use or private-property location documents
  • Fire inspection checklist or permit record
  • Business license and tax records
  • Commissary and servicing records

Fine and operating risk

A King County food permit does not automatically approve every Seattle street or private-property location. Confirm site permissions separately.
