Zoning Report
Washington, DC Zoning
Washington, DC uses the Zoning Regulations of 2016, a citywide zoning code administered through the Office of Zoning, Department of Buildings, and related review bodies. The framework is organized into five major zone categories: Residential, Mixed-Use, Downtown, Production/Distribution/Repair, and Special Purpose. Available source material confirms that development rules are split across multiple subtitles, with general citywide rules in Subtitle C and zone-specific standards in district subtitles such as Subtitle D for Residential House zones. DC also has a comparatively formal discretionary review system, with the Zoning Commission handling map/text amendments and planned unit developments, and the Board of Zoning Adjustment handling variances, special exceptions, and appeals.
