The bill establishes new requirements for the siting of child care centers in Washington State. It mandates that cities and towns must permit child care centers and the conversion of existing buildings for this purpose in all zones, with the exception of industrial zones, light industrial zones, and open space zones. Cities are allowed to impose reasonable restrictions on permits, such as designating pickup and drop-off areas. Additionally, cities that are required to update their comprehensive plans under the growth management act must incorporate these requirements into their regulations during their next update, while other cities must comply within two years of the bill's effective date. The bill also clarifies that cities can allow child care centers in other zones and must provide conditional use approval for centers in industrial or light industrial zones, except near high hazard facilities.

Similar provisions are included for code cities, which are also required to allow child care centers in most zones, with the same exceptions and conditions as regular cities. The bill emphasizes the importance of child care accessibility and aims to streamline the process for establishing child care facilities across various jurisdictions in Washington State. The definition of "child care centers" is aligned with existing law, ensuring consistency in understanding and application.
