Tinley Park, IL Rental Property Rules: Rent Control (2026)

The Illinois Rent Control Preemption Act (50 ILCS 825) prevents municipalities from enacting rent control ordinances. Tinley Park may not cap rental rates, limit rent increases, or impose rent stabilization requirements. Landlords and tenants negotiate rent under general lease and contract principles. Illinois tenants retain significant protections: the Illinois Security Deposit Return Act requires landlords in buildings with 5 or more units to return deposits within 45 days (with itemized deductions); the Illinois Security Deposit Interest Act requires interest on deposits held more than 6 months in buildings with 25 or more units; and the Residential Tenants' Right to Repair Act allows tenants to make limited repairs and deduct from rent. Federal Fair Housing Act and Illinois Human Rights Act prohibit discrimination based on race, color, religion, national origin, sex, familial status, disability, sexual orientation, and source of income. Tinley Park has general property maintenance standards applicable to rental properties and may operate a rental registration program. Any ballot initiative for rent control in Illinois would require state legislative change, not just local action.
