Walla Walla County, WA Food Trucks & Mobile Vendors: Food Truck Permits (2026)

Section 8.04.012, adopted in 2018, layers county-specific mobile food unit rules on top of the Washington Administrative Code food service standards Section 8.04.010 adopts by reference. Subsection A requires mechanical refrigeration sufficient to store all potentially hazardous foods and expressly bars ice chests for that purpose. Subsection B addresses an operator requesting to skip a commissary under RCW 43.20.148: if the unit proposes any food preparation step beyond cold holding, such as cooking an item and then cooling it on board, additional mechanical refrigeration is required to handle that cooling step.

Subsection C requires a commissary-free unit to meet every requirement of WAC 246-215, with the required number and type of sinks depending on the specific menu offered. Subsection D confines all food preparation to inside the mobile unit itself, expressly barring temporary tables and pop-up canopies as prep space. Subsection E allows smokers and barbecues as a cooking source only if an electrical device on the unit can hold food hot afterward and the smoker or barbecue attaches easily to the unit for transport. Subsection F gives the Health Officer discretion to impose additional requirements on any given unit to ensure proper food safety.

Section 8.04.020 makes a violation of the chapter a misdemeanor punishable by a fine of up to three hundred dollars, up to ninety days in jail, or both, with each day of continuing violation a separate offense.
