Illinois has significant rent variation by location: Chicago averages $2,200/month for a 1-bedroom apartment, suburban Chicago (Naperville, Schaumburg, Evanston) runs $1,400-$1,800, and downstate Illinois cities like Peoria, Springfield, and Champaign average $800-$1,000 for a 1-bedroom. Illinois has no statewide rent control law — in fact, Illinois preempts all local rent control ordinances, meaning cities cannot cap rent increases. This makes Illinois's rental market fully market-driven with landlords able to raise rents freely at lease renewal. The standard affordability benchmark is rent under 30% of gross income, but approximately 48% of Chicago renters are rent-burdened (paying over 30%).

Frequently Asked Questions
What is the average rent in Chicago, Illinois?
Chicago average rents in 2025: Studio $1,700, 1-bedroom $2,200, 2-bedroom $2,900, 3-bedroom $3,500. Expensive neighborhoods like Lincoln Park, Gold Coast, and River North run 20-30% higher. More affordable neighborhoods like Bridgeport, Pilsen, and Avondale run 10-20% below average.
Does Illinois have rent control?
No. Illinois's Rent Control Preemption Act (1997) prohibits any municipality from enacting rent control. Chicago specifically cannot implement rent control despite being among the most expensive US rental markets. Landlords can raise rents freely at lease renewal with proper notice (30 days for month-to-month, per lease terms for fixed leases).
What income do you need to afford a Chicago 1-bedroom?
At Chicago's $2,200 average 1-bedroom rent, the 30% rule requires $7,333/month ($88,000/year) gross income. In practice, many Chicago renters live on $55,000-$65,000 by paying 40-50% of income on rent or sharing with roommates.
How much notice does a landlord need to raise rent in Illinois?
For month-to-month leases, Illinois landlords must give 30 days' written notice before a rent increase. For fixed-term leases, the increase cannot take effect until the lease expires. Chicago has additional requirements: 60 days' notice for rent increases over 10% per the Chicago Residential Landlord Tenant Ordinance (RLTO).
Are utilities typically included in Illinois apartment rents?
In Chicago, water and trash are commonly included but gas and electric typically are not. Budget $100-$180/month for gas and electric in a Chicago 1-bedroom. Older Chicago buildings (vintage 1920s-1950s) often have higher heating costs. Suburban and downstate apartments more commonly include no utilities.
