Zoning Report
Milwaukee, WI Zoning
Milwaukee uses a layered zoning system that combines base districts, citywide zoning code standards, and property-specific overlays or special districts. The city’s base districts include residential, commercial, downtown, industrial, planned development, redevelopment, and overlay zones, with official zoning compliance handled through the Department of Neighborhood Services and planning review handled through the Department of City Development. Some projects can proceed under base zoning alone, while others require Board of Zoning Appeals approval, City Plan Commission review, or Common Council action depending on the use, overlay, or requested zoning change.
