You should talk to a lawyer. 30 days notices needs to be in writing, not a phone call. If you were given written notice you should have until the end of next calendar month, but talk to a lawyer about all of the specifics. You can go to the Daley Center Monday-Friday by 8:30 to sign up and talk to a lawyer in room 601 for free, have you list of questions. Also, Google Chicago Landlord Tenant Ordinance. It applies to all Chicago rentals. It will spell out your rights and is very tenant rights focused.
