Illinois Landlord Rights (2026): What You Can and Cannot Do
Your tenant stopped paying in July. You changed nothing, said nothing, and now it is September. A friend told you to change the locks. Your brother-in-law said you cannot touch the unit for a year. Both of them are wrong, and both of them are confident.
I file more than 150 evictions a year for Illinois property owners. Most of the trouble I see starts with a landlord who did not know where the line was. This page draws the line. It covers what an Illinois landlord may do, what the law forbids, and the three habits that lose cases.
You have the right to your rent, your property, and your day in court. You do not have the right to take the unit back yourself. Illinois lets you serve a 5-day notice for unpaid rent, a 10-day notice for a lease violation, and a 30-day notice to end a month-to-month tenancy. After the notice expires, you file an eviction case. A judge signs the order and the Sheriff enforces it. Every self-help shortcut, from changing the locks to shutting off the heat, hands the tenant a claim against you and restarts your clock.

Seven Rights Every Illinois Landlord Has
1. The right to be paid on time
Rent is due on the day the lease says. When it is late, you may serve a 5-day notice under 735 ILCS 5/9-209. The notice demands the full amount. The clock starts the day after service, and weekends count. If the tenant pays everything within the five days, the tenancy continues. If not, you may file. My 5-day notice guide has the free form and the service rules.
2. The right to enforce the lease
A tenant who breaks a lease term gets a 10-day notice under 735 ILCS 5/9-210. Unauthorized occupants, pets, damage, and running a business from the unit all qualify. In Chicago the tenant gets a chance to cure most breaches inside the 10 days. Some breaches cannot be cured. A fake identity on the application is one. Felony drug activity in the unit is another, and it has its own faster notice under 735 ILCS 5/9-120.
3. The right to end a month-to-month tenancy
With no written lease, or after a lease has expired, the tenancy runs month to month. You end it with a 30-day notice under 735 ILCS 5/9-207. You do not need a reason. Chicago changes the count for longer tenancies. See evicting without a lease.
4. The right to enter the unit
You may enter to inspect, repair, and show the unit. In Chicago, RLTO 5-12-050 requires two days' notice except in an emergency, and the tenant "shall not unreasonably withhold consent." A tenant who blocks lawful access breaks the lease. My guide to tenants who refuse entry covers the notice and the remedy.
5. The right to hold a deposit and deduct for damage
You may hold a security deposit and deduct for damage beyond normal wear. Since January 1, 2024, the Illinois Security Deposit Return Act, 765 ILCS 710, applies to every residential landlord in the state. You have 30 days to itemize deductions and 45 days to return the balance. Get it wrong and the penalty is twice the deposit plus the tenant's attorney fees. The full rules are in my security deposit guide.
6. The right to a court order and the Sheriff
After a valid notice expires, you file an eviction case under Article IX of the Code of Civil Procedure. If you win, the judge enters an eviction order. The Sheriff, not you, removes the tenant. My step-by-step eviction guide walks the whole case.
7. The right to a money judgment
Your eviction complaint may include a claim for the unpaid rent. If your lease has an attorney-fee clause, you may claim fees too. Collecting from a tenant who could not pay rent is hard. The judgment still follows the tenant.
Every landlord right in Illinois runs through the same three steps. Serve the correct written notice. Wait out its clock without accepting rent. File in court. Any plan that skips a step is not a plan. It is a lawsuit against you.
Seven Things the Law Does Not Let You Do
Never change the locks, shut off utilities, or remove a tenant's property without a court order. Only a judge can end a tenant's possession, and only the Sheriff enforces the order.
- No lockouts, anywhere in Illinois. Changing the locks, shutting off a utility, or removing belongings to force a tenant out is prohibited statewide. In Chicago the tenant recovers up to two months' rent or twice the damages, plus attorney fees, and the City fines $200 to $500 a day. In suburban Cook County a lockout that draws a criminal charge runs $500 a day, and the tenant recovers at least two months' rent.
- No utility shutoffs. Heat, water, and power stay on until the Sheriff has done the eviction.
- No removing belongings. The pile in the unit is the tenant's property until a judge says otherwise. Chicago even defines abandonment with a checklist. An empty-looking unit is not on it. See when a tenant abandons the apartment.
- No tape-on-the-door notices. Posting a notice on an occupied unit does not count as service under 735 ILCS 5/9-211. It is my most frequent intake call, and it never produces a winning case. Read why door posting fails.
- No partial rent after a 5-day notice. Accepting part of the rent after service kills the case. There is no reservation-of-rights letter that fixes it. Details on accepting partial rent.
- No retaliation. You may not end a tenancy, raise rent, or cut services because a tenant complained to a code inspector or exercised a legal right. The tenant gets a defense and a claim. See when a tenant claims retaliation.
- No evicting the victim. Under the Safe Homes Act, 765 ILCS 750, a tenant who flees domestic or sexual violence can end rent liability with written notice, and can require a lock change within 48 hours. You may still evict the person who caused the violence. My Safe Homes Act guide covers the deadlines.
Some tenants are worth a deal, not a case. A tenant with years of on-time rent and one documented hardship may pay more under a signed payment plan than any judgment will return. A tenant who will leave by a date certain may be worth a cash-for-keys payment. The deal only works if the tenant has already been sued or hands over the keys before being paid. My guides to cash for keys and waiting versus filing show the math.
Chicago and Cook County Add Rules
Illinois law is the floor. Two local ordinances build on it, and each one turns a routine mistake into a fee-shifting lawsuit.
| Rule | Chicago (RLTO) | Suburban Cook (RTLO) |
|---|---|---|
| Deposit return | 45 days, with interest | 30 days |
| Deposit penalty | 2x deposit plus fees | 2x deposit |
| Non-renewal notice | 30, 60, or 120 days | 30 days; 60 days for a year-to-year tenancy |
| Lockout | Prohibited, damages plus fees | Prohibited; $500 a day if charged, at least 2 months' rent |
Outside Chicago and suburban Cook County, ending a month-to-month tenancy or declining to renew takes 30 days' written notice. Chicago's notice tiers depend on how long the tenant has lived there: 30 days under six months, 60 days from six months to three years, and 120 days past three years. The RLTO excludes owner-occupied premises with six units or fewer, except for the notice tiers and the lockout ban. The Cook County RTLO does not apply inside Chicago. My RLTO Summary guide walks the ordinance heading by heading, my RLTO defense page shows what these cases cost when they go wrong, and my Cook County RTLO guide covers the suburbs.
Chicago also gives landlords an Early Resolution Program date in every eviction case. Read what it adds to the timeline in my Early Resolution Program guide.
The Three Habits That Lose Cases
1. Accepting money after the notice
A 5-day notice demands the full balance. A partial payment after service knocks out the demand. You start over and lose another month. After a judgment, an unlabeled payment can reinstate the tenancy unless a writing says it is for use and occupancy or applied to the judgment.
2. Serving the notice yourself, badly
Under 735 ILCS 5/9-211 you may hand the notice to the tenant, leave it with a resident age 13 or older, or send it by certified or registered mail with a returned receipt. In Chicago, personal service is the method that holds up. Certified mail and posting invite problems.
3. Leaving an adult occupant off the case
Every adult living in the unit gets named or covered as an unknown occupant. Miss one and you go back several steps to serve that person. It is painful, not fatal, and it is avoidable.
How Long It Takes

Frequently Asked Questions
Can a landlord evict a tenant without going to court in Illinois?
No. Only a judge can end a tenant's right to possession, and only the Sheriff enforces the order. Changing the locks, shutting off utilities, or removing belongings is an illegal lockout. In Chicago the tenant can recover damages and attorney fees for it. Serve the correct notice, wait out its clock, and file the case.
How much notice does a landlord have to give in Illinois?
Five days for unpaid rent, ten days for a lease violation, and thirty days to end a month-to-month tenancy. Chicago requires more notice to end a longer tenancy: 60 days after six months and 120 days after three years. Felony drug activity in the unit has its own notice under 735 ILCS 5/9-120.
Can I keep the security deposit if the tenant owes rent?
You may apply the deposit to unpaid rent and to damage beyond normal wear. You must still itemize the deductions within 30 days and return any balance within 45 days under the Illinois Security Deposit Return Act. Chicago and suburban Cook County add their own rules. Miss a deadline and the penalty is twice the deposit.
What happens if I accept partial rent after serving a 5-day notice?
The case dies. A partial payment after service knocks out the notice, and you serve a new one and wait out a new clock. There is no letter that reserves your rights around this rule. If the tenant offers money after the notice, call your lawyer before you take it.
Do I have to give a reason to end a month-to-month tenancy?
No. Illinois lets you end a month-to-month tenancy with a 30-day notice for any reason or no reason. You may not end it as retaliation for a complaint or a legal right the tenant exercised. In Chicago, a tenancy longer than six months needs 60 days of notice, and one longer than three years needs 120 days.
What rights do landlords have in Illinois?
You have the right to be paid on the day the lease says, to serve a 5-day notice the day after rent is late, to serve a 10-day notice for a lease violation, to end a month-to-month tenancy on 30 days' written notice, to enter for repairs and inspections on reasonable notice, to apply the deposit to unpaid rent and real damage, and to take the case to a judge and then to the Sheriff. Chicago and suburban Cook County add rules on top of these.
What can a landlord not do in Illinois?
You cannot change the locks, shut off heat or water, remove doors, or move the tenant's belongings out to force a move. Only a court order ends possession and only the Sheriff enforces it. You cannot accept partial rent after a 5-day notice and keep the case alive. You cannot retaliate against a tenant for a code complaint or for using a legal right. You cannot post a notice on the door of an occupied unit and call it service.
How far behind on rent does a tenant have to be before I can start an eviction in Illinois?
One day. Rent is late the day after the lease's due date, and you may serve the 5-day notice that day. The notice demands the full amount. If the tenant pays everything inside the five days, the tenancy continues. If not, you may file. Waiting a month or two does not strengthen the case. It adds unpaid rent you will probably never collect.
What are the new landlord laws in Illinois for 2026?
The Summary of Rights under the Safe Homes Act became mandatory on January 1, 2026. Public Act 103-1031 requires the IDHR summary attached as the first page of every written residential lease, new or renewal, with signatures, at a $100 to $2,000 penalty. My lease guide covers the requirement. Chicago landlords must also keep attaching the RLTO Summary and the current year's deposit-interest rider.
