In two-family and multiple-dwelling buildings with attached dwelling units, which are of a row house nature with party walls between dwelling units and private or semiprivate entrances, each dwelling unit shall have provided adjacent to one exterior face and open space extending twenty feet horizontally outward at right angles the full width of the building face. For each dwelling unit which has two exterior faces parallel to each other, there shall be provided adjacent to the second exterior face an open space extending ten feet horizontally outward at right angles the full width of the building face. (See Diagram B for illustration of open space requirements.)
In addition, the following conditions shall apply:
(a) Vehicular parking areas and driveways shall be prohibited from both required open spaces.
(b) An open space which fulfills one of the above requirements for one dwelling unit shall not be used to satisfy the requirements for another dwelling unit, except for adjacent dwelling units on the inside corner of a building or adjacent buildings whose exterior walls are at right angles to each other, in which case the required yards may overlap. (See Diagram C for illustration of interior corners where open space requirements may be shared.)
