Legal Question in Landlord & Tenant Law in Illinois

Re: bed bugs

If you know for certain that the landlord rented it to you knowing that it was infested, you may be able to use that as a bargaining chip, but this is rather hard to prove. Unfortunately, the whole north side has experienced a big upswing in the bed bug population. What you can do is inform the landlord and demand they spray the building. Let the landlord know he is in violation of section 5-12-070 of the Chicago Residential Landlord Tenant Ordinance if he fails to fix the problem.

I found a website for you that should help with your questions. See http://www.illinois-attorney.com/110.htm
