Governed by the Illinois Eviction Act (originally effective July 1, 1982), the residential eviction process in Illinois requires strict adherence to state procedures. The state explicitly prohibits "self-help" evictions; attempting to force a tenant out outside the bounds of the court can lead to severe financial liabilities.
Official Law Citation: The rules and regulations outlined on this page are governed by the Illinois Eviction Act (735 ILCS 5/Art. IX).
No Self-Help Evictions
Under no circumstances can an Illinois landlord legally force an eviction by:
- Changing the locks.
- Shutting off utilities.
- Removing a tenant's belongings from the property.
- Harassing the tenant.
The only way to legally remove a tenant is to win an eviction lawsuit (a Forcible Entry and Detainer action) and have the county sheriff execute the order.
Notice Requirements
Before filing an eviction lawsuit, the landlord must provide the tenant with formal written notice. The type of notice depends on the reason for the eviction.
5-Day Notice (Non-Payment of Rent)
When a tenant fails to pay rent on time, the landlord must serve a 5-Day Notice to Quit (735 ILCS 5/9-209).
- The notice gives the tenant 5 full days to pay the overdue balance.
- If the tenant pays in full within the 5 days, the eviction process halts, and the lease remains intact.
- If partial payment is offered, the landlord should be cautious, as accepting it may restart the notice period.
10-Day Notice (Lease Violations)
For a material breach of the lease (e.g., unauthorized pets, excessive noise, unregistered occupants), the landlord must issue a 10-Day Notice to Quit (735 ILCS 5/9-210).
- This notice gives the tenant 10 days to correct the violation or move out.
- If the issue is severe or involves illegal drug activity, the timeline may be accelerated depending on local ordinances.
30-Day Notice (No-Fault Termination)
To terminate a month-to-month tenancy without "just cause," the landlord must serve a 30-Day Notice (735 ILCS 5/9-207).
- For tenancies from year to year, a 60-day written notice is required to terminate the tenancy at the end of the year (735 ILCS 5/9-205).
- The notice must give an entire rental period's warning (e.g., notice given on May 15th means the tenant must be out by June 30th).
The Court Process
If the tenant remains on the property after the notice period expires, the landlord proceeds with a lawsuit.
- File the Complaint: The landlord files an eviction complaint with the circuit court in the county where the property is located.
- Serve the Summons: A county sheriff or designated special process server must serve the summons and complaint to the tenant, detailing the court date.
- The Hearing: If both parties appear, the judge will listen to evidence. Landlords must bring copies of the lease, the notice, proof of service, and a rent ledger.
- Order of Possession: If the judge rules in the landlord's favor, they will issue an Order of Possession. This gives the tenant a definitive date by which they must leave—usually 7 to 14 days later.
Sheriff Execution
If the tenant still refuses to leave after the date set in the Order of Possession, the landlord must take the order to the local sheriff's office. Only the sheriff is authorized to forcibly remove the tenant. The timeline for the sheriff's executing the order ranges from a few weeks to a few months, depending heavily on county backlog.
Retaliatory Evictions
Illinois strictly prohibits retaliatory evictions. In 2025, the Landlord Retaliation Act (765 ILCS 721) took effect, bolstering protections. Under this Act, a landlord may not knowingly terminate a tenancy, increase rent, decrease services, or refuse to renew a lease because the tenant has in good faith:
- Requested repairs.
- Filed a code violation complaint.
- Joined or organized a tenant's union.

Frequently Asked Questions
▶What is the Illinois eviction process and how long does it take?
Illinois eviction follows the Forcible Entry and Detainer process. For non-payment, landlords serve a 5-Day Notice to Quit. For lease violations, a 10-Day Notice to Quit is required. To terminate a month-to-month tenancy without cause, 30 days' notice is needed. Self-help evictions (changing locks, removing belongings) are strictly prohibited. In Chicago, the CRLTO imposes additional notice requirements and tenant cure periods that landlords must follow.
▶What are the Illinois landlord-tenant laws every property owner should know?
Illinois landlord-tenant law is a mix of state statutes (765 ILCS) and powerful local ordinances. The state provides a baseline framework covering security deposits, eviction procedures, and habitability, but cities like Chicago (CRLTO), Evanston, and suburban Cook County (RTLO) impose significantly stricter requirements around deposit returns, late fees, and tenant remedies. Non-compliance with local ordinances can result in severe penalties.
Read the complete guide▶What is the Illinois security deposit limit and return deadline?
Illinois state law does not cap security deposit amounts, but Cook County, Evanston, and Oak Park limit deposits to 1.5 times the monthly rent. State law requires deposits to be returned within 45 days of move-out. If deductions are made for property damage, an itemized statement with paid receipts must be provided within 30 days. Chicago's CRLTO requires deposits in interest-bearing accounts with annual interest payments to tenants.
Read the complete guide▶Does Illinois have rent control or caps on rent increases?
No. Illinois passed the Rent Control Preemption Act, which prohibits any city or municipality from enacting rent control measures. There are no state limits on how much a landlord can increase rent. During a fixed-term lease, rent cannot be increased unless the lease explicitly allows it. For month-to-month tenancies, landlords must provide at least 30 days' written notice before any increase takes effect.
Read the complete guide▶What is the Chicago RLTO and how does it affect landlords?
The Chicago Residential Landlord and Tenant Ordinance (CRLTO) is one of the most powerful local tenant protection laws in the country. It imposes strict rules on security deposit handling (interest-bearing accounts required), mandates specific lease disclosures, limits late fees, and provides tenants with aggressive remedies including the ability to recover twice the deposit amount if a landlord violates the ordinance. Landlords operating in Chicago must comply with both state law and the CRLTO.
Read the complete guide▶What disclosures must Illinois landlords provide to tenants?
Illinois landlords must disclose lead-based paint hazards for pre-1978 buildings, radon hazards if testing reveals elevated levels, flood zone status and flooding history within the past 10 years (new in 2025), and shared utility meter arrangements where tenants may be paying for common area utilities. Chicago adds additional required disclosures including building code violations, foreclosure proceedings, and the full text of the CRLTO summary.
Read the complete guide▶What are Illinois landlord maintenance obligations and habitability standards?
Illinois enforces an implied warranty of habitability, requiring residential properties to be fit for human occupation and comply with building, housing, and health codes. Tenants can use the 'repair and deduct' remedy (765 ILCS 742) for repairs costing less than $500 or half a month's rent — they give 14 days' written notice, have the work done professionally, and deduct the cost from rent. Chicago's CRLTO provides even stronger tenant remedies for habitability failures.
Read the complete guide▶What are the late fee rules for rental properties in Illinois?
Illinois state law does not impose a specific cap on late fees but requires them to be reasonable and stated in the lease. Chicago's CRLTO is more restrictive, capping late fees at $10 per month for rent under $500, and 5% of the monthly rent amount for higher rents. The CRLTO also mandates a 5-day grace period before any late fee can be assessed. Violations of these limits can trigger tenant remedies under the ordinance.
