IL HB4998

Limits security deposits to a maximum of one month's rent for residential units, with exceptions for seasonal dwellings and owner-occupied cooperative apartments

Caps rental application fees at $20 and background/credit check fees at $20 or actual cost (whichever is less); landlords must waive check fees if applicants provide reports from the past 30 days

Prohibits late fees unless rent is more than 5 days overdue, with fees capped at $50 or 5% of monthly rent (whichever is less)

Requires landlords to provide prospective tenants with an Attorney General-created "Landlord and Tenant Rights and Laws" disclosure sheet at contract signing

Violations constitute consumer fraud under the Consumer Fraud and Deceptive Business Practices Act, with enforcement by the Attorney General; preempts home rule units from adopting less restrictive regulations
