Chicago 2 flat - Zoning Violation

[Marvin Anaya]

Hello BPers!  Can anyone please recommend a Building and Zoning Attorney??

I closed on a 2 flat in Chicago last month. This used to be a single family home and the previous owner converted it into a two-flat. As the story goes, I received a letter from Cook County (A.k.a CrooK County) saying there is a violation against the property. 

Violation date: Nov. 12th, 2014 - Violation code: B5.3-1A - Violation description - The owner is doing interior remodel, making a single family residence into a multi-family unit.

Here's the kicker - this was an REO FANNIE MAE owned property. I purchased through FHA financing, and I used the rental income of the 2nd unit in order to qualify. The home was listed as a multi-unit apartment building, and the zoning does allow such units here. I am due in COURT in June for this violation... ANY help is much appreciated!! THANK YOU!
