The purposes of the D-5-R zone are to promote high-density residential development through housing requirements and incentives in areas near Mount Vernon Square and in the Mount Vernon Triangle while accommodating high-density commercial and mixed-use development.
A building with frontage on a designated primary or secondary street shall meet the design requirements on Subtitle I § 602, unless the building fronts on a designated primary street in the Mount Vernon Triangle Principal Intersection Sub-Area and is therefore governed by Subtitle I § 553.2.
The following Downtown Sub-Areas are found within the D-5-R zone: Chinatown, Massachusetts Avenue Corridor and Mt. Vernon Square, Mount Vernon Triangle, Mount Vernon Triangle Principal Intersection.
|Floor Area Ratio (max.)1, 2||Height (ft.)2||Penthouse Height (ft.)/Stories||Lot Occupancy

The D-5-R zone is not subject to the Inclusionary Zoning provisions of Subtitle C, Chapter 10; however, a building in the D-5-R zone may generate or use credits in accordance with Subtitle I, Chapters 8 and 9, which explains the credit system relating to Transferable Development Rights (“TDR”) or Combined Lot Development (“CLD”) rights.
A building on a lot in the D-5-R zone must provide the equivalent of at least 3.5 Floor Area Ratio (“FAR”) of residential use before any non-residential uses may be provided on the lot, unless the development meets one of the exceptions in Subtitle I § 547.2. The permitted height of a building in the D-5-R zone is based on the right-of-way width of the street upon which it fronts, as detailed in the table below.
A front setback is not required, except as otherwise required by Subtitle I § 612 in the case of a designated primary street segment.
1 The maximum permitted FAR for a building shall be the density achievable within the height and bulk permitted by the zone and any applicable sub-area regulations: (a) If all of the building’s FAR is devoted to residential use; (b) If all FAR exceeding the non-residential density permitted in Subtitle I § 547.5 is devoted to residential use; or (c) If conditions (a) or (b) are not satisfied, through the use of credits provided for by Subtitle I, Chapters 8 and 9.
2 Unless: (a) the residential requirement is reduced or eliminated by Subtitle I §§ 200.2 or 200.3, or Subtitle I § 547.4; (b) relieved of a residential requirement by the provisions of Subtitle I § 305.3; (c) the residential requirement is reduced by up to 1.4 FAR through constructing or financially assisting affordable housing pursuant to Subtitle I § 305.7; or (d) the requirement is met using the credit procedures enabled by Subtitle I, Chapters 8 and 9.
3 Subject to applicable regulations governing courts, side or rear yards, front setback or build-to lines, easements or historic preservation.
4 Unless modified in in Subtitle I, Chapter 3 or by regulations governing a specific Downtown sub-area.
5 No parking is required in this zone, but parking spaces provided are subject to Subtitle C, Chapter 7.
