New tweak: Zoning history for any Chicago building has been clarified

Published on Feb. 19, 2017 by Steven Vance


We’ve made two small but helpful changes:

  1. Our zoning map has been updated for every zoning change made by the time of the December 2016 City Council meeting, and many changes made in January and February 2017.
  2. Our Zoning History feature for Pro members has been redesigned to make it easy to know when the zoning was changed.

The Zoning History section of an Address Snapshot now shows the date the ordinance changing a parcel’s zoning classification was changed. If the city’s zoning map doesn’t include the ordinance date, then we show the date someone edited the map to include that change. And if that date doesn’t exist, well, we just don’t know.

Previously, the Zoning History feature on each Address Snapshot showed the current zoning based on whichever “snapshot” of the zoning map we had in a random period. We only periodically obtain the latest zoning map from the city’s planning department.
