Washington, DC · Title 11 DCMR (2016 Zoning Regulations)
UNZONED designates federal government property, national monuments, and other land not subject to DC zoning jurisdiction. Examples include the White House grounds, U.S. Capitol grounds, national memorials, and other federal installations. DC Zoning Regulations of 2016 do not apply to these parcels. Development, use, and modifications are governed by federal agencies such as the General Services Administration (GSA), National Park Service (NPS), or the Architect of the Capitol -- not the DC Office of Zoning.
