What rent control exemptions apply in Illinois?

Where Illinois has a statewide or local rent cap, the statute typically exempts several categories: newer construction (usually buildings less than 15 years old, sometimes "rolling" 15-year window), single-family homes owned by individual landlords (often with disclosure requirement), affordable housing already regulated under separate program, owner-occupied buildings of 2 to 4 units, and units already covered by a different rent stabilization program. The exemptions are statute-specific and frequently litigated. A landlord claiming an exemption usually must give the tenant a written notice of the exemption status (form prescribed by statute) at lease signing or before the increase. Illinois has no statewide advance notice specific to rent increases. 735 ILCS 5/9-207 sets 30 days as the month-to-month termination default, which landlords treat as the minimum for rent changes. No state rent cap; local rent control is preempted statewide.
