Zoning Handbook

The purposes of the Foggy Bottom Residential House R-17 zone are to: 

  • Enhance the residential character of the area by maintaining existing low-scale residential uses, human scale streetscape, and historic character;
  • Enhance the human-scale streetscape by maintaining the public space in front of the buildings as landscaped green spaces and limiting future curb cuts; 
  • Require a scale of development consistent with the Comprehensive Plan; and the characteristics of the low scale residential townhouse neighborhood that formed the basis on which the area was designated a historic district;
  • Preserve areas planned as open backyards and alleyways that provide the only access to historic alley dwellings, and to protect the light, air, and privacy that they provide; and
  • Encourage greater use of public transportation through use of the nearby Metrorail Station, so as to protect the narrow residential streets and alleys from the deleterious effects of disruptive excessive traffic. 

The R-17 is intended to permit single dwelling unit attached rowhouses on small lots
