How to Evict Squatters in Chicago: Ejectment, SB 1563, and What Landlords Need to Know

Have you had a terrible nightmare that someone stole everything from you? Maybe you know someone who came home from a family trip and found strangers living in their investment property, refusing to leave. Maybe you’ve seen the TikToks of people throwing furniture out of Airbnb windows. As a small landlord juggling a few rentals in the suburbs, you pour sweat into those places. They fund your kids’ future or that dream vacation. But squatters turn everything upside down, costing you lost rent, repair bills, and sleep you will never get back.

Updated April 2026: This guide reflects the passage of Illinois SB 1563, signed into law by Governor Pritzker in July 2025 and effective January 1, 2026. Police can now remove squatters as trespassers in many situations.

The legal system has not historically done much to help property owners facing squatters. Police would shrug and call it a civil matter. Courts would drag the process out for months while your property sat idle and bills piled up. That was especially frustrating for landlords already navigating Chicago’s high taxes and dense regulatory environment. But the law has changed, and there are real options available to you now, both through the courts and through law enforcement.

This guide covers the ejectment action under Illinois law and explains how SB 1563 has changed the game for property owners. It also walks through the practical steps you should take the moment you discover unauthorized occupants in your property. If you own rentals anywhere in Chicagoland, this is information worth having before you need it.

Understanding Squatters vs. Tenants in Chicago

Squatters are not tenants. That is the first and most important distinction when you are figuring out how to evict squatters in Chicago. A tenant has a lease and pays rent. A squatter moves in without permission and without any agreement. They exploit vacant units, often targeting foreclosed or abandoned properties, and sometimes they show up with forged leases claiming they rented the place from someone who had no authority to rent it.

Illinois law does create some wrinkles here. Squatters can theoretically claim “adverse possession” after 20 years of open, continuous occupation, or after seven years if they hold a flawed title document and have been paying property taxes. In practice, that almost never happens. Most squatter situations are far shorter and far less organized than what the adverse possession statute contemplates.

The real challenges are financial and personal. The average squatter problem costs a Cook County landlord roughly $6,500 in missed rent, and that does not account for the property damage that usually comes with it: broken windows, changed locks, trashed or stolen appliances. On top of the dollar figures, there is the stress of knowing someone is occupying your property without permission and the legal system is making you jump through hoops to get it back.

The distinction between squatter and tenant matters enormously for your legal strategy. If you have never accepted rent from the occupants and no lease exists, they are likely pure squatters, which opens faster legal paths like ejectment actions. But if you accept even one rent payment, or if there is any documentation suggesting a landlord-tenant relationship, they gain tenant protections under the RLTO. At that point, you are in standard eviction territory, which is a longer and more regulated process. Getting this classification right at the outset can save you weeks and keep eviction lawyer fees to a minimum.

The Legal Framework for Evicting Squatters in Chicago

Illinois law generally favors property owners in squatter disputes, but you have to follow the process precisely. Inside Chicago city limits, the Chicago Residential Landlord and Tenant Ordinance applies. In the suburbs, Cook County has its own version. Both require proper notices before you can go to court.

For true squatters who have never paid rent, the strongest tool in your arsenal is 735 ILCS 5/6-101, the ejectment statute. This allows a single-action filing focused solely on recovering possession. You do not need to chase money damages as part of this case. You demand immediate possession, notify everyone in the unit (and yes, this is one of the rare situations where posting notice on the door is acceptable), and then you file.

The ejectment route skips several of the procedural hurdles that come with standard evictions. A typical eviction requires 5-day, 10-day, or 30-day notices depending on the specific issue, along with personal service or certified mail for those notices. When no rent history exists between you and the occupant, ejectment cuts through much of that.

Time matters in these cases. Every day a squatter stays in your unit, you lose rental income and the property continues to deteriorate. A five-day delay can easily represent $250 or more in lost rent alone, and that number only grows. The sooner you begin the legal process, the sooner you recover your property.

SB 1563: Illinois’s New Anti-Squatter Law

Governor Pritzker signed Senate Bill 1563 into law in July 2025, and it took effect on January 1, 2026. This is the most significant change to Illinois squatter law in years. The new law allows police to treat squatters as trespassers and remove them without forcing the property owner through a full court eviction, provided you can show proof of ownership and that no legitimate tenancy exists.

SB 1563 also makes it a criminal offense to present fake documents or false identities to claim a right to occupy property. That is a direct response to the forged-lease scam, which accounts for a large percentage of the squatter cases our firm handles. The bill passed with near-unanimous bipartisan support, which tells you something about how widespread the problem had become.

In practice, this means your first call when you discover squatters should now be to the police. Bring your deed, your tax records, and any evidence that no lease exists. If the situation is straightforward, law enforcement may be able to handle it on the spot. For more complicated situations where the squatter claims to have a lease or where the facts are disputed, you will still need to go through the court process, but SB 1563 has meaningfully expanded your options.

When to Use Ejectment vs. Standard Eviction

Ejectment works best when no tenant relationship exists at all, meaning you have never taken rent and there is no lease. Under 735 ILCS 5/6-101, you file a possession-focused action, prove ownership, show proper notice was given, and demonstrate the absence of any rental relationship. The case can be filed in the regular eviction courts, and when the facts are clean, you will get your unit back considerably faster than through a standard eviction.

Standard eviction is the right path if the occupants have paid rent at any point, or if they overstayed a lease. I have a whole series of articles covering those scenarios in detail. If you have a lease, or if your unknown occupant has been paying rent monthly, that is where you should start.

Self-help remedies are off the table entirely. Changing locks yourself, cutting utilities, or physically removing belongings will expose you to serious legal liability. You risk fines of $500 per day or worse. I understand the frustration, but the legal channels exist for a reason, and taking shortcuts almost always costs more in the long run than doing it the right way from the start.

Step-by-Step: How to Evict Squatters in Chicago

When you discover squatters in your property, here is the process from start to finish. These steps draw from the cases our firm has handled and reflect both the traditional ejectment path and the new options available under SB 1563.

Document everything first. Take photos of the property inside and out. Note the date you discovered the unauthorized occupants. Gather your proof of ownership: the deed, tax records, and any evidence that no lease was ever signed. If you do not have copies of your deed or tax records readily available, the firm can pull them for you.

Call the police. Under SB 1563, report the situation as trespassing. Bring your ownership documents. If the facts are clear and the occupants cannot produce a legitimate lease, law enforcement may remove them on the spot. If they cannot, get a police report, because you will need it for court.

Serve a demand for immediate possession. If police involvement does not resolve the situation, use the proper notice form to demand that the occupants vacate. Because no rent was ever accepted, you can post this notice on the door, which simplifies service considerably.

File for ejectment. Go to the Cook County Circuit Court and file under 735 ILCS 5/6-101. Include your affidavit of service. The filing fee is $287.

Serve the squatters through proper channels. You will need either a private investigator or the sheriff to serve the court papers on the occupants. This is not something you can handle yourself.

Attend your court date and present your evidence. Bring your deed, your notice documentation, the police report, and your photos. If you prevail, the court will issue an order for possession. You then take that order down to the 7th floor of the Daley Center and hand it to the sheriff’s office.

Coordinate the sheriff’s removal. The sheriff handles the actual lockout. Once that is complete, change every lock on the property immediately and consider installing a security system or cameras to prevent the same thing from happening again.

When the process runs smoothly, you are looking at roughly 75 to 90 days from filing to recovery. That timeline can save you thousands of dollars compared to letting the situation drag out or using the wrong legal mechanism.

Prevention Strategies to Avoid Squatters in Your Chicago Properties

Removing squatters is expensive and time-consuming even under the best circumstances. Prevention is far cheaper. If you own rental property in Chicagoland, these measures will significantly reduce your exposure to squatter situations.

Secure vacant units aggressively. Board windows if necessary. Install alarm systems. Conduct regular checks on any property that is sitting empty. In the suburbs, frequent drive-bys go a long way. If you need to board a property up properly, I recommend DAWGS, which specializes in vacant property security.

Invest in real locks. The deadbolts you pick up at Home Depot will hold for about five minutes against someone who is determined to get in. Go to an actual locksmith and have professional-grade hardware installed on every exterior door. I do not feel safe with a five-minute delay on my own property, and you should not either.

Pay your property taxes on time. Consistent tax payments block any adverse possession argument before it can start. While you are thinking about asset protection, setting up an LLC for your rental properties creates liability shields and tax advantages that protect your personal assets if something goes sideways.

Screen tenants carefully and monitor your properties. Thorough background checks weed out risk, but the bigger issue is what happens when a property is on the market. About 80% of the squatter cases our firm sees involve forged leases where a fraudster impersonated the property owner. Regular drive-bys and keeping an eye on listing sites for your address can catch these schemes before they take root.

Do not take physical action yourself. I cannot stress this enough. If you change locks, cut utilities, or physically remove someone’s belongings from a property in Chicago, you are looking at a minimum fine of $500 per day under the RLTO. That makes self-help the single most expensive mistake a landlord can make in this situation, every time.

These prevention measures cost almost nothing compared to dealing with a squatter after the fact, and they free you up to focus on growing your portfolio instead of fighting over properties you already own.

Common Mistakes Landlords Make When Dealing with Squatters

The biggest mistake I see is delay. Landlords hope the squatters will leave on their own, or they spend weeks trying to figure out what to do before contacting an attorney. That hesitation works against you. Every day that passes without legal action strengthens the squatter’s position and costs you money. When you act within the first few days of discovering the problem, the entire process moves faster and the outcome is almost always better.

The second most common mistake is accepting money from the occupants. Sometimes a squatter will offer to pay rent as a way of buying time, and a landlord who is desperate for income will take it. The moment you accept that payment, you have created a landlord-tenant relationship, and the squatter now has tenant protections. Do not accept rent, do not sign anything, and do not negotiate directly. Get an attorney involved and report the situation to police under SB 1563.

The third mistake is the self-help I mentioned above: changing locks, shutting off water, removing the front door. I have seen landlords do all of these things. In every case, it made the situation worse and more expensive. The courts and law enforcement have the tools to handle this properly, and using those tools is always cheaper than cleaning up after a self-help attempt gone wrong.

How Much Does It Cost to Evict a Squatter in Chicago?

The hard costs for an ejectment filing include the $287 court filing fee, process server or sheriff service fees (typically $50 to $150), and attorney’s fees. The total legal cost for a straightforward ejectment case generally runs between $1,500 and $3,500 depending on complexity. If the squatter contests the case or raises counterclaims, costs can go higher. For a detailed breakdown of attorney pricing, I wrote a full guide on how much an eviction lawyer costs in Chicago.

Compare those numbers to the cost of doing nothing. At $6,500 in average lost rent plus property damage, the math is straightforward. Legal action pays for itself, and the sooner you file, the less you lose overall. If you factor in the security deposit complications that can arise when occupants claim tenant status, the financial argument for acting quickly becomes even stronger.
