The Mixed-Use (MU) zones provide for mixed-use developments that permit a broad range of commercial, institutional, and multiple dwelling unit residential development at varying densities. The MU-15 through MU-22 zones specifically cover the Dupont Circle area with the intention of protecting and enhancing the unique characteristics of the neighborhood.

The purposes of the Dupont Circle Mixed-Use zones are to:

  • Require a scale of development consistent with the nature and character of the Dupont Circle area in height and bulk and ensure a general compatibility in the scale of new buildings with older, low-scale buildings;
  • Enhance the residential character of the area by maintaining existing residential uses and controlling the scale, location, and density of commercial and residential development;
  • Preserve areas planned as open gardens and backyards and protect the light, air, and privacy that they provide;
  • Enhance the streetscape by maintaining the public space in front of buildings as landscaped green spaces and limited curb cuts on Connecticut Avenue; and
  • Encourage greater use of public transportation and the free circulation of vehicles through public streets and alleys.

The MU-15 zone is intended to permit moderate-density areas predominantly developed with residential buildings.
