Concerning mobile dwellings.

HB 1443 would require Washington cities and counties to allow at least one mobile dwelling (such as tiny homes on wheels or recreational vehicles) on residential lots that already have an existing home, provided the lot is in an urban growth area and not in protected shorelines or critical areas. It mandates specific utility connections for these dwellings, including dedicated electrical circuits and plumbing links to the main home's systems, while prohibiting property associations (like HOAs) from banning them on qualifying lots. The bill applies to lots zoned for residential use and expires January 1, 2028. This directly affects local governments, property associations, and residents seeking to add mobile dwellings to existing residential properties.
