The bill amends RCW 64.55.010 to redefine the criteria for what constitutes a "multiunit residential building." Specifically, it introduces an exemption for buildings that contain 12 or fewer units and are no more than three stories tall, provided that at least one story is designated for parking (either above or below ground) or retail use. This change expands the previous definition, which only exempted buildings with 12 or fewer units that were no more than two stories.

In addition to the new exemption, the bill maintains existing definitions and clarifications regarding terms such as "attached dwelling unit," "building enclosure," and "developer." The adjustments aim to provide more flexibility in the classification of smaller residential buildings, potentially encouraging the development of such structures by reducing regulatory burdens associated with multiunit residential classifications.
