The Zoning Board of Appeals reviews land use issues that pertain to the Chicago Zoning Ordinance, including proposed variations from the zoning code, special uses that require review to determine compatibility with adjacent properties, and appeals of decisions made by the Zoning Administrator. Established in 1923, the board has five members that are appointed by the Mayor with City Council consent. Staff services are provided by the Zoning Ordinance Administration Division of the Department of Planning and Development.
