Steven Vance posts key findings from a newly released tool that maps zoning changes in the city of Chicago.

Among the findings:

  • The city of Chicago has approved118 zoning changes so far this year.
  • The average amount of time a zoning change takes to be approved, after the ordinance has been submitted, is 116 days. The longest zoning change ordinance took 714 to be approved.
  • The shortest amount of time for a zoning change was 35 days—16 zoning changes were approved that quickly.

The zoning changes map is designed to alert residents of proposed zoning changes—along with city-owned land sales, property tax incentives, and historic landmarks considered by Chicago City Council.
