Rezoning to Add a Unit

[Hemang S.]

Hi all. I am under contract on a Chicago property that has 3 cashflowing units but the zoning cert says it is only a 2-unit + commercial space (which has been turned into a 3rd unit. It is zoned RT-4). I am wondering what the rezoning process is like and any advice you have from that front. If rezoning is just time consuming, I imagine a price reduction on this property would make it worthwhile. Thanks for your help and tips in advance!
