Search

There are three options to search for a location on the map: property identification number (PIN), property address, and street intersection. Type your choice into the search box and click the green arrow.

Examples

  • PIN (either 10-digit or full 14-digit) – 17094610150000
  • Property Address – 69 W Washington, Chicago
  • Street Intersection – Washington Dearborn

The results of your search will be displayed on the left of the screen. Click on the desired result and the map will zoom to that location. For a property search (PIN or address), the property characteristics will be displayed on the left of the screen.

Measure

The measure tool allows you to measure area, distance or XY location. Once the desired measurement type and measurement units are selected you can click on the map to find your measurement.

Print

Click the print tool and follow the dialog to print a copy of the displayed map into an Adobe PDF file.

Themes

The themes tool displays a list of themes that represent groups of data layers with a common theme. Click on one of the themes and the associated map layers will be displayed on the map.

Property Comparables

The compare tool allows you to compare the selected property with similar properties. The window pane on the left of the screen allows you to specify any combination of comparison criteria. Once the comparison criteria is set, click “Find Comparable Properties” and a list of properties will be displayed in the “Results” tab and the location of those properties will be displayed on the map. Click on a property in the list to display summary data and zoom to that property location on the map.
