I tried to get the assessor to correct this a few years back and apparently they didn't.
4231 N. Kenmore is an 8 unit approximately 11 year old apartment building. Just north and next door is an identical building owned and built by the same owner.
The address next door is 4237.
4231 is listed as an apartment building by the assessor and pays the appropriate taxes. 4237 is listed as a vacant lot.
4231 PIN Number 14-17-403-016-0000
4237 PIN Number 14-17-403-015-0000
If you check out the pictures of the properties here and here, you will see that there is no vacant lot.
From the Treasurer site you can find the taxes:
Now 4231 pays about $20,600 in taxes a year.
4237 pays about $8500
If you go to the Campaign Disclosure/Contribution site and type in Gibbons Management you will find many fine contributions to Shiller and Tunney. Perhaps Hugh is bored and will look to see if Gibbons made other donations through his various extensive property holdings.
