This bill establishes a regulatory framework for microenterprise home kitchens in Washington State, defining key terms such as "domestic residence," "home kitchen," and "microenterprise home kitchen operation." It mandates the state board of health to adopt operational rules by July 1, 2027, which will include guidelines for food sales and catering, while limiting operations to a maximum of 30 individual meals per day and 90 meals per week. Operators must obtain a permit from their local health jurisdiction, submit a standard operating procedure for food handling, and comply with hygiene standards during inspections conducted by local health authorities. The bill emphasizes that permits are nontransferable and must be displayed on-site.

Furthermore, the legislation clarifies that microenterprise home kitchen operations are allowed as residential property uses, provided they adhere to local noise ordinances and do not advertise externally. It prohibits local governments from imposing additional restrictions or requiring permits beyond those established by the state. The bill also empowers local health jurisdictions to conduct inspections during normal business hours with prior notice and to impose penalties for violations. The Department of Health is tasked with maintaining statistics on these operations and reporting to the legislature by July 1, 2027. The provisions of the act are set to expire on December 31, 2029, unless specific funding is secured by June 30, 2025.
