In Illinois, the only lawful way for a landlord to remove a tenant is by filing an eviction case in court under the state Eviction Act (the former Forcible Entry and Detainer Act, 735 ILCS 5/9-101 and following). Changing the locks, removing your door, hauling out your belongings, or shutting off your heat, water, gas, or electricity to drive you out is not allowed, even after a lease ends or rent is overdue. If you live in Chicago, the Residential Landlord and Tenant Ordinance (RLTO) and a separate anti-lockout ordinance give you especially strong remedies: a locked-out tenant can recover possession plus the greater of two months' rent or twice the actual damages, plus reasonable attorney's fees, and an illegal lockout can carry city fines of up to $500 per day. These are general explanations, not legal advice, and local rules vary, so confirm the current Illinois and local provisions or talk with an Illinois attorney before acting.
What counts as an illegal self-help eviction in Illinois
Self-help eviction means trying to force a tenant out without a court order. Illinois courts have long held that a landlord must go through the eviction process and cannot take possession by force or trickery. Conduct that is generally prohibited includes:
Changing or adding locks, or removing the locks, doors, or windows so you cannot get in.
Removing your belongings or putting them on the curb.
Shutting off or interfering with electricity, gas, water, heat, or other essential services.
Threats, repeated harassment, or removing the only working bathroom or kitchen to make the unit unlivable.
It does not matter whether you are behind on rent or your lease has expired. Until a judge signs an eviction order and the sheriff carries it out, you still have the right to stay in your home.
The lawful path: court eviction
A proper Illinois eviction runs through the circuit court for your county. The landlord must first give the correct written notice (commonly a 5-day notice for unpaid rent, a 10-day notice for certain lease violations, or a 30-day notice to end a month-to-month tenancy, with timelines that can differ for federally subsidized housing and during local emergencies). If you do not leave, the landlord files an eviction complaint, you get served and a court date, and only a judge can order you out. Even then, the landlord cannot personally remove you, only the county sheriff enforces the eviction order. Any shortcut around this is the self-help conduct the law forbids.
Penalties a landlord faces
The specific damages depend on where the property is located:
Chicago (RLTO). Under the city's ordinance, a tenant who is unlawfully locked out or whose essential services are cut off can recover possession and the greater of two months' rent or twice the tenant's actual damages, plus reasonable attorney's fees.
Chicago anti-lockout ordinance. A separate Chicago ordinance makes an illegal lockout a violation that police can respond to, with fines that can run up to roughly $500 for each day the lockout continues.
Cook County and Evanston. Cook County's Residential Tenant and Landlord Ordinance and the City of Evanston ordinance contain their own lockout and utility-shutoff protections and damage remedies that closely track Chicago's.
Rest of Illinois. Where no local ordinance applies, tenants generally rely on common-law claims for wrongful eviction and on the eviction statute's requirement of a court order; courts can award actual damages and, in appropriate cases, additional relief.
Because the exact figures, caps, and attorney-fee rules differ by municipality and change over time, confirm the current language for your city before relying on a number.
Emergency steps to regain possession or restore service
If you are locked out or your utilities are cut, acting quickly matters:
Document everything: photos of changed locks, removed belongings, or a dark meter, plus dates, times, and what the landlord said.
In Chicago and other covered areas, call the police or 311 about an illegal lockout; officers can sometimes help you get back in and may cite the landlord.
Ask the landlord in writing to restore access and services immediately, keeping a copy.
Go to court. A tenant can ask a judge for emergency relief to be let back in or to have utilities turned back on; legal aid offices and tenant clinics can move fast on these requests.
If your safety is at risk, you are facing large losses, or the landlord refuses to back down, this is a strong moment to involve a tenant lawyer or legal aid organization, especially because attorney's fees may be recoverable.

Frequently asked questions
Can my Illinois landlord change the locks if I owe rent?
No. Even if you are behind on rent, the landlord cannot lock you out, remove your door, or take your belongings. The only lawful route is an eviction case in the circuit court, ending with a sheriff-enforced order. A self-help lockout can expose the landlord to damages and, in Chicago, daily fines.
What can I recover if I'm illegally locked out in Chicago?
Under the Chicago RLTO, a tenant who is unlawfully locked out or denied essential services can generally recover possession plus the greater of two months' rent or twice the actual damages, along with reasonable attorney's fees. Confirm the current ordinance language, as figures can change.
Is shutting off my utilities treated the same as a lockout?
Yes, in covered areas. Chicago, Cook County, and Evanston ordinances treat cutting off heat, water, gas, or electricity to force a tenant out as a prohibited interruption of tenancy, carrying the same kinds of damages as a physical lockout. Statewide, it can support a wrongful-eviction claim.
Who actually carries out a legal eviction in Illinois?
After a judge enters an eviction order, only the county sheriff can physically remove a tenant. The landlord cannot do it personally and cannot act before the court order is in place. Anything the landlord does on their own to push you out is the self-help conduct the law forbids.
What should I do first if I come home to a changed lock?
Take photos and notes, then in Chicago or other covered cities call the police or 311 about an illegal lockout. Ask the landlord in writing to restore access right away. If they refuse, you can seek emergency court relief, and a legal aid office or tenant lawyer can help you act quickly.
