City Launches New Online Zoning Map

January 26, 2017

The Chicago departments of Planning & Development and Information Technology (DoIt) today implemented a new online zoning map that improves user functions and includes a host of new features.

The new map at provides searchable zoning and related information for all parcels located within the city’s borders. It also enables users to search Sidwell maps, 80-acre maps, Planned Developments, Tax Increment Financing Districts, Landmark Districts, historic properties, transit stations, and other features.

The new map replaces a geographic information systems (GIS) interface that was first launched in 2002.

"The new map brings the City’s technology in line with the enormous advancements made in online mapping over the past decade,” said DPD Commissioner David L. Reifman. “Residents, businesses, real estate developers, and other visitors will find it more useful and easier to navigate than ever."

Many of the map’s improvements are in its core infrastructure. "Thanks to new software and servers, users should see improved load times, fewer pop-ups, and less down time," Reifman said.

The map also allows users to directly access Zoning Board of Appeals decisions and offers street-level, Cook County Assessor's Office photos for each property.
