Illinois Has No Rent Control. Here’s the Law.
I’m Mike Fisher with MF CashFlow Property Management, part of M Property Group LLC, a Licensed Illinois Real Estate Broker. Rent control is one of those topics where I hear more fear than facts, so let me give you a straight answer.
Illinois rent control law for rental owners is clear today: there is no rent control in Illinois. Not in Chicago. Not in Cook County. Not in any south or west suburb you’re invested in. Illinois passed the Rent Control Preemption Act in 1997, and it’s still the law. It bars every municipality and county from enacting any ordinance that controls the rent you charge. The Illinois General Assembly has the full text online under 50 ILCS 825. One law, statewide, and it preempts everything local. You set your rent based on the market. That’s it.
Why Rental Owners Keep Asking About Illinois Rent Control
I get this question all the time, and I get why. Owners watch what happens in California and New York and they get nervous. Rent control has done real damage to rental housing markets in those states, and when you see headlines about proposals in Springfield, it’s fair to wonder if Illinois is headed the same direction.
Here’s my honest take after 35 years investing in real estate. The political pressure isn’t going away. Advocacy groups are active and there are legislators who want the Preemption Act repealed. I’m not saying it’s coming next year. I’m saying pay attention. Because if rent control ever does pass in Illinois, it almost always gets tied to the rent you’re currently collecting. Owners who haven’t raised rents in years get locked into a below-market rate permanently. That’s the trap. If you’re not sure where your rents stand against the market today, a free rental analysis is the right first move.
The Rules That Are Already Hitting Your Bottom Line
No rent control, but there are real regulations in place right now that cost you money if you get them wrong. Here’s what matters depending on where your property sits.
In Chicago, the Residential Tenants’ and Landlords’ Ordinance caps late fees at $10 on the first $500 of monthly rent, plus 5% above that. In suburban Cook County outside the city, the Cook County RTLO covers most of that territory and caps late fees at $10 on the first $1,000 of rent, plus 5% above. Cook County also caps security deposits at 1.5 times monthly rent and requires an itemized return within 30 days. Get these wrong and you’re writing checks back to tenants out of your own pocket.
Source of income protection is statewide now. Since January 2023, Illinois law protects Section 8 vouchers and other housing assistance across the entire state, not just in Chicago. You can’t turn a qualified tenant away just because they’re using a voucher. Know that rule no matter which suburb you’re in.
In Cook County, criminal history screening is governed by the Just Housing Amendment. You prequalify applicants on all other criteria first, and only then may you run a criminal background check. Arrest records can’t be used to deny, and before denying anyone over a conviction from the past three years, you must do an individualized assessment. Convictions more than three years old generally can’t be the basis for a denial. Getting your screening process right from day one is critical. We’re intentional about how we structure tenant screening for exactly this reason.
Check your local code for heat and temperature minimums. What applies in one suburb may be a different standard two towns away. Know your local code.
What to Watch Going Forward
The Preemption Act is solid today, but the fight over it isn’t done. A bill to repeal it, Senate Bill 1260, was filed in Springfield in January 2025 and has not passed, and more repeal efforts may follow. The best thing you can do right now is make sure you’re at market rent, your leases are tight, and your properties are actually performing.

FAQ: Rent Control in Illinois
Is there rent control anywhere in Illinois right now? No. The Rent Control Preemption Act (50 ILCS 825) bars all municipalities and counties from enacting rent control. You can charge market rent anywhere in the state today.
Could Illinois pass rent control in the future? It’s possible if the legislature repeals the 1997 Preemption Act. A repeal bill, Senate Bill 1260, was introduced in 2025 but has not passed. Worth watching closely if you own rental property here.
Are there rules that limit what I can collect from tenants? Not on base rent anywhere in Illinois. But late fees are capped under the Chicago and Cook County ordinances, security deposits are regulated in Cook County, and rejecting Section 8 vouchers is prohibited statewide. The rules vary by location, so know what applies where your property actually sits.
