This bill introduces new regulations regarding the placement of homes on wheels in residential areas within cities and counties in Washington State. Specifically, it mandates that any city or county planning under RCW 36.70A.040 must allow at least one home on wheels on each residentially zoned lot, provided certain conditions are met, such as the presence of an existing housing unit and adequate utility services. The bill outlines requirements for utility connections, including electrical service and plumbing, and stipulates that cities and counties must enforce standard inspection procedures for utility hookups without requiring inspections of the homes on wheels themselves.

Additionally, the bill prohibits associations of apartment owners, condominium associations, homeowners' associations, and common interest community associations from creating any restrictions that would effectively prevent the placement of homes on wheels on residential lots, with these provisions set to expire on January 1, 2028. This legislation aims to enhance housing flexibility and accessibility by accommodating mobile dwellings in urban growth areas while ensuring that necessary utility connections are maintained.
