Illinois Eviction Process & Timeline: Steps, Notices, and How Long It Takes

In Illinois, an eviction starts with a written notice, and the required notice period depends on why the landlord wants you out. For unpaid rent, the law generally requires a 5-day notice to pay or move. For a lease violation (other than rent), the usual notice is 10 days. To end a month-to-month tenancy with no lease, a landlord typically must give 30 days written notice. Only after a notice expires can a landlord file a court case. In Illinois this lawsuit is called an Eviction action (historically known as forcible entry and detainer) under the state's Eviction Act, and it is filed in the Circuit Court for the county where the property sits. A landlord cannot legally change the locks, remove your belongings, or shut off utilities to force you out. Only a judge can order an eviction, and only the county sheriff can carry it out.

The notices that start an Illinois eviction

Before any court filing, Illinois requires a written demand or notice. The most common ones are:

• 5-day notice (nonpayment of rent): Gives you five days to pay the full amount owed. If you pay within those five days, the landlord generally must accept it and cannot proceed on that notice.
• 10-day notice (lease violation): Used for breaking a lease term other than rent, such as an unauthorized pet or occupant. Unlike the rent notice, a 10-day notice does not always have to give you a chance to fix the problem.
• 30-day notice (ending a month-to-month tenancy): Used when there is no fixed lease and the landlord simply wants to end the arrangement. Longer notice may apply for longer tenancies or under local ordinances.

Local rules can change these numbers. The City of Chicago's Residential Landlord and Tenant Ordinance (RLTO) and Cook County's tenant ordinance add protections and notice requirements that differ from the statewide baseline, so always check whether a city or county rule applies to your address.

Filing the case and getting served

If the notice period passes and the issue is not resolved, the landlord files an Eviction complaint with the Circuit Court clerk and pays a filing fee. The court issues a summons telling you when and where to appear. You must be properly served, usually by the sheriff or a licensed process server. The first court date is often set a couple of weeks out, though crowded dockets in Cook County and other large counties can push it later.

• Read the summons carefully for the exact date, time, and courtroom.
• Missing the court date can result in a default judgment against you, so appear even if you think you have a strong defense.
• Keep copies of your lease, rent receipts, texts, and any repair requests.

The hearing and your right to fight it

At the hearing you can tell your side. Tenants in Illinois have real defenses, and an eviction is not automatic just because a landlord filed. Common defenses include:

• The notice was defective, served improperly, or the time had not run out.
• You actually paid the rent, or the landlord refused a timely payment.
• The landlord failed to maintain a safe, habitable unit, or is retaliating for a complaint or for requesting repairs.
• The eviction is based on discrimination prohibited by fair housing law.

If you and the landlord reach an agreement, the court may enter an agreed order, sometimes giving you extra time to move or to pay. If the judge rules for the landlord, the court enters an order for possession (an eviction judgment). Because the stakes are high and the rules are technical, this is a point where a tenant attorney or a local legal aid organization can make a real difference, often at low or no cost.

The order, the writ, and the sheriff

An eviction judgment usually includes a short stay before enforcement, commonly giving the tenant a window of time before the landlord can act. After that period, the landlord asks the court to issue the order to the sheriff to remove the tenant. In Illinois this enforcement step is what actually puts a tenant out, and it must be performed by the sheriff, not the landlord. The sheriff schedules the lockout and supervises it. In busy counties like Cook, there can be a wait of several weeks before the sheriff reaches your case, and lockouts are sometimes paused during extreme winter weather.

Throughout all of this, self-help eviction remains illegal. A landlord who locks you out, removes your doors or windows, takes your property, or cuts off heat or water to force you out can be liable to you for damages.

A realistic Illinois timeline

Every case is different, but a rough picture looks like this:

• Notice period: 5, 10, or 30 days depending on the reason.
• Filing to first court date: often two to three weeks, longer in large counties.
• Hearing to judgment: sometimes the same day, sometimes continued for weeks if contested.
• Judgment to sheriff lockout: typically a stay of a week or more, plus the sheriff's scheduling backlog.

In an uncontested, smooth case this can run roughly five to eight weeks from notice to lockout; a contested case or a crowded docket can stretch it to several months.
