I’m Mike Fisher with MF CashFlow Property Management, part of M Property Group LLC, a Licensed Illinois Real Estate Broker. If you own rental property in the Chicago suburbs, fair housing laws are something you can’t afford to get wrong. The owners who get hit with complaints usually aren’t trying to discriminate. They’re running on outdated information, or they never updated their process when the rules changed. After 35 years investing in real estate and thousands of deals across the south and west suburbs, let me walk you through what actually matters here.
The Protected Classes: Federal Law Is Just the Starting Point
Federal fair housing law covers seven protected classes: race, color, national origin, religion, sex, disability, and familial status. That’s the baseline. Illinois adds more through the Illinois Human Rights Act, including ancestry, age, marital status, sexual orientation, gender identity, military status, and order of protection status. And then local ordinances layer on top of that.
If your property is in Cook County or Chicago, you’re playing by three sets of rules at once. Don’t assume that being outside city limits means local ordinances don’t apply to you. In a lot of cases, they do. Know what applies to your specific address before you write a lease or post a listing.
Source of Income: The Rule That’s Tripping Up Owners Right Now
As of January 2023, Illinois state law prohibits source-of-income discrimination, statewide. That means you can’t turn someone down because they’re paying with a Section 8 housing choice voucher or other government rental assistance. It doesn’t matter if your property is in Chicago, Tinley Park, or anywhere else in Illinois. That protection applies everywhere in the state.
“I don’t take Section 8” is no longer a legal position you can hold. You have to evaluate every applicant on the same criteria. If you want to see how a legally sound screening process works and still protects your investment, take a look at how we handle tenant screening.
Criminal History Screening in Cook County: The Just Housing Amendment
If your rental is in Cook County, the Just Housing Amendment changes how background checks work. The rule: qualify applicants on income, rental history, and references first. Only after they meet your other criteria can you look at criminal history, and that assessment has to be individualized, not a blanket rejection. Convictions older than three years generally can’t be used to deny housing.
You can’t see a conviction on a background check and turn the application down on the spot. The law requires you to weigh the nature of the offense, how long ago it happened, and what the person’s track record looks like since then. If you’re self-managing in Cook County and haven’t updated your screening process for this, a free rental analysis with us is a good place to start.
Late Fees and Security Deposits: Get the Numbers Right
The “$20 or 20%” late fee number that floats around landlord forums comes from the Illinois self-storage statute. It does not apply to residential leases. If that’s what’s in your lease right now, fix it.
Under the Chicago Residential Landlord and Tenant Ordinance, late fees are capped at $10 on the first $500 of monthly rent plus 5% above that. Under the Cook County RTLO, which covers most of suburban Cook County, it’s $10 on the first $1,000 plus 5% above. The Cook County RTLO also caps security deposits at 1.5 times monthly rent, with a 30-day deadline to return it with an itemized statement after move-out. Miss that deadline and you’re writing a check you didn’t plan on. If you want to see how these constraints affect your actual returns, our ROI calculator can help you run the real numbers.
Watch How You Write Your Rental Listings
Fair housing violations don’t only happen during the application process. Listing language can create problems too. Phrases like “perfect for young professionals” or “great for a couple” suggest preferences the law doesn’t allow. Describe the property: features, location, lease terms. The U.S. Department of Housing and Urban Development has plain-language guidance on fair advertising at hud.gov. If you’re writing your own listings, read it before you post.
