Building: A structure requiring permanent placement on the ground that has one (1) or more floors and a roof supported by columns or walls. When separated from the ground up or from the lowest floor up, each portion shall be deemed a separate building, except as provided elsewhere in this title. The existence of communication between separate portions of a structure below the main floor shall not be construed as making the structure one (1) building.
Building Area: The maximum horizontal projected area of a principal building and its accessory buildings. Except for outside balconies, this term shall not include any projections into open spaces authorized elsewhere in this title, nor shall it include portions of a building that do not extend above the level of the main floor of the main building, if placed so as not to obstruct light and ventilation of the main building or of buildings on adjoining property.
Building area shall not include: Building components or appurtenances dedicated to the environmental sustainability of the building; cornices and eaves; sills, leaders, belt courses, and similar ornamental or structural features; awnings, serving a window, porch, deck or door; uncovered stairs, landings, and wheelchair ramps that serve the main floor; and chimneys, smokestacks, or flues.

Building, Height of: In other than R, RF, RA, RC-1, CG-1, and D-1 zones, the vertical distance measured from the level of the curb, opposite the middle of the front of the building to the highest point of the roof or parapet or a point designated by a specific zone district; in Residential (R) zones the vertical distance measured at the existing grade at the midpoint of the building façade of the principal building that is closest to a street lot line to a point designated in the zone district. Berms or other forms of artificial landscaping shall not be included in measuring building height.
The term “curb” shall refer to a curb at grade. When the curb grade has been artificially changed by a bridge, viaduct, embankment, ramp, abutment, excavation, tunnel, or other type of artificial elevation or depression, the height of a building shall be measured using Rules of Measurement for Height (Subtitle B § 308).
Building Line: A line beyond which property owners have no legal or vested right to extend a building or any part of the building without special permission and approval of the proper authorities; ordinarily a line of demarcation between public and private property, but also applied to building restriction lines, when recorded on the records of the Surveyor of the District of Columbia.

Building, Separate: Structures that are separated from the ground up by common division walls or contain multiple sections separated horizontally, such as wings or additions, are separate buildings. Structures or sections shall be considered parts of a single building if they are joined by an enclosed connection that is fully above grade, is heated and artificially lit; and either a common space shared by users of all portions of the building, such as a lobby or recreation room, or space that is designed and used to provide free and unrestricted passage between separate portions of the building, such as an unrestricted doorway or walkway.
Bulkhead: A retaining wall or protective structure along a shoreline whose primary purpose is to stabilize, hold, or prevent earth or backfill from eroding or washing away.
