Legal Question in Landlord & Tenant Law in Illinois

If your leases expire and there are no fixed renewal options on guaranteed terms (rare), then for a renewal the landlord can change terms. If your building is covered by the Chicago Residential Landlord and Tenant Ordinance (RLTO) the landlord's only obligation as to renewals is to let you know in advance if the lease will NOT be renewed. However, the landlord in fairness should also let you know what the estimated additional charges will be and you certainly can inquire as to what the landlord thinks they will be, as though you too are negotiating a new lease. At the same time, this sounds a bit unusual, as though this is the only way the landlord can make you think twice about staying if the goal is to empty the building out as a way around non-renewal notices. It may also depend on whether rent is going up.... All in all rather unusual but I can't think of anything that would make it unlawful per se. I would suggest having an attorney look at the total proposal.
