I’m Mike Fisher with MF CashFlow Property Management, part of M Property Group LLC, a Licensed Illinois Real Estate Broker. Illinois rental law changes for landlords have been stacking up at a pace I haven’t seen in a long time, and with 35 years of investing in this market, that’s saying something. A lot of these changes hit Chicago-area owners hard, and if you’re managing properties in the south or west suburbs right now without knowing these rules cold, you’re sitting on risk you don’t even see yet. Here’s what actually matters.
Source-of-Income Protection Is Now Statewide
This is the one that blindsides people the most. As of January 2023, the Illinois Human Rights Act makes it illegal to refuse a rental applicant or treat them differently because they use a housing voucher, like Section 8. This isn’t just a Chicago thing anymore. It’s every city, every suburb, every county across Illinois. The Illinois Department of Human Rights handles enforcement, and complaints have real teeth. If you’re advertising “no vouchers” anywhere, pull it down today. You don’t have to lower your standards. You just can’t make the voucher itself the reason for a denial.
Cook County Criminal History Screening Has a Two-Step Process
If your property is in Cook County, the Just Housing Amendment changes how you screen for criminal records. You can’t pull a background check upfront. First you qualify the applicant on income, rental history, and references. Only after they pass all that can you run a criminal background. Even then, the ordinance generally limits what you can weigh to convictions within the past three years, and you’re required to do an individualized assessment before denying anyone based on their record. This is one of the biggest reasons tenant screening has to be done right. Mess up the order of operations here and a fair housing complaint follows.
Late Fees and Security Deposits Have Hard Caps
I hear landlords throwing around wrong numbers on late fees all the time, and it’s going to cost them. Here’s what the ordinances actually say. In Chicago, the Residential Tenant and Landlord Ordinance caps late fees at $10 on the first $500 of monthly rent, plus 5% on any amount above that. In suburban Cook County, the Cook County RTLO caps them at $10 on the first $1,000, plus 5% above that threshold. Charging more gives a tenant leverage to use against you in court. The Cook County RTLO also caps security deposits at 1.5 times the monthly rent and requires you to return the deposit with an itemized statement within 30 days of move-out. Miss that deadline and you could owe double. Don’t miss it.
Know What Your Property Should Be Earning Before Anything Else
All of this compliance work matters a lot more when your property is actually performing. If your rent is off, you’re already losing, and no amount of legal knowledge fixes that. Start with a free rental analysis to see where you stand in today’s market, and run your actual numbers through the ROI calculator to see what your property should really be returning. Knowing the law keeps you out of trouble. Knowing your numbers keeps you in business.
FAQ: Illinois Rental Law Questions Landlords Are Searching
Can I refuse a Section 8 tenant anywhere in Illinois? No. Since January 2023, source-of-income is a protected class under Illinois state law, statewide. You can still screen for income, credit, and rental history. You just can’t reject someone solely because they’re using a voucher.
What’s the maximum late fee I can charge in suburban Cook County? The Cook County Residential Tenant and Landlord Ordinance caps it at $10 on the first $1,000 of monthly rent, plus 5% on any amount above that. Going over that limit is a liability you don’t want sitting in your lease.
Do Cook County criminal background check rules apply in the suburbs? Yes. The Just Housing Amendment covers Cook County broadly, not just Chicago. If your property is in suburban Cook County, the two-step qualification process and individualized assessment requirement apply to you.
