The bill introduces a new section to chapter 66.24 RCW, establishing a license endorsement for domestic breweries, microbreweries, and domestic wineries to conduct off-site and pop-up retail sales, service, and consumption of alcohol. This endorsement, available for an annual fee of $50, allows these establishments to sell beer and wine for both on-premises and off-premises consumption at designated locations, subject to specific requirements. These include obtaining authorization from the board, limiting operations to one location at a time, and adhering to restrictions on the number of events held annually. The bill also outlines the necessary conditions for the designated areas, such as ensuring an enclosed boundary and compliance with age restrictions for alcohol sales.

Additionally, the bill mandates that the board must notify local authorities and consider objections from nearby schools, churches, and public institutions before approving an endorsement holder's request to operate at a proposed location. It specifies that if an existing liquor licensee is already within 500 feet of a school, the board may still approve the request despite objections. The bill defines key terms related to the operation of off-site and pop-up activities, ensuring clarity in the implementation of these new provisions.
