(a)The front of the building shall be the side upon which the principal entrance is located;
(b)Open space in front of the entrance shall be required that is equivalent either to the required rear yard in the zone district in which the building is located or to the distance between the building restriction line recorded on the records of the Surveyor of the District of Columbia for the subdivided lot and the public space upon which the subdivided lot fronts, whichever is greater;
(c)A rear yard shall be required; and
(d)If any part of the boundary of a theoretical lot is located in common with the rear lot line of the subdivided lot of which it is a part, the rear yard of the theoretical lot shall be along the boundary of the subdivided lot.

(c)If there are not at least two (2) entrances or exits from the means of ingress or egress, a turning area shall be provided with a diameter of not less than sixty feet (60 ft.); and
(d)The requirements of paragraphs (b) and (c) of this subsection may be modified if the Board finds that a lesser width or diameter will be compatible with, and will not be likely to have an adverse effect on, the present character and future development of the neighborhood; provided, that the Board shall give specific consideration to the spacing of buildings and the availability of resident, guest, and service parking.
2516.7Where not in conflict with the Act to Regulate the Height of Buildings in the District of Columbia, approved June 1, 1910 (36 Stat. 452, as amended; D.C.
