“Zero lot line townhouse development” means the division of land to create attached residential units with common (or “party”) walls. Each unit is located on a lot in such a manner that one or more of the dwelling’s sides rests on a lot line. Each unit has its own entrance opening to the outdoors (to the street, alley, or private tract) and, typically, each house is a complete entity with its own utility connections. Although most townhouses have no side yards, they have front and rear yards. The land on which the townhouse is built, and any yard, is owned in fee-simple. (Ord. 3176 § 5, 2016)
