The Office of Zoning (OZ) is an independent District of Columbia agency which was created in 1990 by an Act of the City Council. Effective in 1991, OZ provides professional, technical, and administrative assistance to the Zoning Commission (ZC) and the Board of Zoning Adjustment (BZA). The agency receives and processes all zoning related applications, which may be for a zoning change handled by the ZC, or to seek relief from a zoning regulation provision handled by the BZA. OZ schedules ZC and BZA public meetings and hearings and provides follow-up information on their actions and decisions; coordinates the zoning process with the Office of Planning and other District and Federal agencies; maintains, updates and publishes the District’s Zoning Regulations (through the District’s Office of Documents) and the Zoning Map; prepares records of appealed ZC and BZA cases for the courts; and handles all administrative matters associated with the daily functioning of the office. OZ consults with the Office of Corporation Counsel regarding legal issues and monitors the District’s legislative process to keep the ZC and the BZA apprised of matters affecting zoning. OZ also provides public information about the zoning process, the Zoning Regulations, the zoning of specific properties, and the status of cases pending before the ZC and the BZA. OZ, the ZC, and the BZA receive legal advice from the Office of the Attorney General (OAG) to ensure the legal sufficiency of their actions and decisions.
