The bill mandates that cities and towns in Washington State must permit child care centers and the conversion of existing buildings for such use in all zones, with the exception of industrial zones. It allows cities 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 are given a two-year timeframe to comply.

Similarly, the bill applies to code cities and towns, establishing the same requirements for permitting child care centers and their conversions. Code cities are also allowed to impose reasonable restrictions and must adhere to the same timeline for incorporating these regulations into their comprehensive plans. This legislation aims to facilitate the establishment of child care facilities across various zones, thereby addressing the growing need for child care services in the state.
