D.C. Mun. Regs. tit. 11, r. 11-C1700
Plaza regulations are intended to provide spaces in private developments that serve as transitional spaces between streets or pedestrian rights-of-ways and the entrances of buildings. These spaces are intended for public use, and may also be used for temporary commercial displays and other activities, such as café seating. The plaza regulations are intended to ensure that such spaces are appropriately designed, including suitable lighting and landscaping.
Plaza space required by specific zones and subject to the standards of this chapter are intended to be publically accessible and are encouraged to be built adjoining other plazas to maximize open space.
Plaza regulations apply only on lots of ten thousand square feet (10,000 sq. ft.) or more in area in the MU-10 and CG-4 zones.
