Liquor License (WSLCB) & MAST — Seattle
Serving alcohol in Seattle requires a Washington State Liquor and Cannabis Board license plus MAST permits for serving staff.
Overview
Liquor licensing is a state function through the Washington State Liquor and Cannabis Board (WSLCB), applied via the state Business License Application + a Liquor Addendum-Retail. Decisions take 60–120 days (King County often >90), with a temporary license sometimes available after 30–45 days.
Common restaurant licenses: Spirits/Beer/Wine Restaurant (all alcohol on-premise), Beer/Wine Restaurant, or Tavern. You must secure your location before processing, and post public notice on the premises for 20 consecutive days; local government may object.
Every server/manager who serves or supervises alcohol service needs an individual MAST permit (Class 12 for 21+, Class 13 for 18–21). State liquor fees rose ~50% in 2025 (2SSB 5786).
