1. Licensed Chicago Contractors, my website that tracks what developers and the city are proposing to build or demolish in your neighborhood, is now called Chicago Cityscape.
2. I’m grateful to Ian Dees who helped me get property tax data for 2009-2013 for over 1.4 million PINs (property identification numbers) in Cook County.
I’m going through various parts of the property tax data and figuring out how to integrate it with Chicago Cityscape. The first time Ian got the data I found out I didn’t tell him to get the right PINs. I think I’ve fixed that now.
As part of this process I’m checking properties somewhat randomly, based on the permits I’m browsing. I most recently viewed a Wrigley Field building permit at 1060 W Addison Street – for a Zac Brown concert – so I searched its PIN and how much the property is “worth”. Here goes:
|Year||Amount Billed||Assessed Value|
Notice how the assessed value dropped over $2 million from 2009 to 2010. And even though it had three unique assessed values, the annually changing tax rate adjusted the amount billed. You can see this information on the Cook County Property Info portal.
