How to prepare for a vendor permit in Seattle

Last checked: 2026-10-08 · Español

Identify products, food, equipment and location. Check Seattle business licensing and ask whether the organizer’s trade-show arrangement covers you.

For food, identify the appropriate temporary permit through Public Health Seattle & King County. Confirm fees, training and operating requirements in the current application.

Seattle’s 90-day special-event planning timeline concerns organizers; it is not a universal deadline for every vendor.

Save your documents and review the draft before submitting the official application.
