The Central Business (C-4) District shall be designed for the downtown core that comprises the retail and office centers for both the District of Columbia and the metropolitan area.
The C-4 District shall be large enough to provide an adequate area for a variety of commercial, retail, and business uses to serve the metropolitan area, but nevertheless compact enough to retain its identity.
The C-4 District also shall contain high-density residential and mixed use developments.
Except as provided in chapters 20 through 25 of this title, in a C-4 District, no building or premises shall be used and no building shall be erected or altered that is arranged, intended, or designed to be used except for one (1) or more of the uses listed in §§ 751 through 755.
