Single family homes have just one dwelling unit. Duplex homes share a single wall with a dwelling unit on either side of the wall. Townhomes are single-family dwelling units constructed in a group of three or more attached units in which each unit extends from the foundations to the roof with open space on at least two sides. Accessory dwelling units (ADUs) are defined as a smaller, independent residential dwelling unit located on the same lot as a stand-alone single family or duplex home.

Multifamily low-rise buildings have four or more separate units connected by shared walls located in one building with three or fewer habitable stories above ground.
