These developments are to be characterized by one-family dwellings or two one-family unit constructed one above the other with common parking areas and shared open space.

For purposes of determination of what constitutes a "lot," structures are to be considered as group dwellings and one or more units are permitted on the lot. It is not necessary that each unit have its own street frontage and open area, but usable open space, which can be located at various levels of the development, must be provided for and be directly accessible to each dwelling unit.

In all instances, there shall be provided on the same lot an area or garage containing one parking space for each family and the provisions of Section 14-1402(2) are not applicable for this district.
