Illinois Eviction Notice Overview
Illinois requires a 10-day notice for lease violations under 735 ILCS 5/9-210. There is no 14-day notice period in Illinois eviction law. The Illinois Forcible Entry and Detainer Act governs evictions, and cases are filed in the Circuit Court of the county where the property is located. Chicago and Cook County have additional tenant protections under the Chicago Residential Landlord and Tenant Ordinance (RLTO), which imposes stricter requirements than state law.
Illinois distinguishes between non-payment (5-day notice under 735 ILCS 5/9-209) and lease violations (10-day notice under 735 ILCS 5/9-210). The 10-day notice must describe the violation and demand that the tenant either cure or vacate within 10 days. Cook County (Chicago), DuPage County, Lake County, and Will County handle the highest eviction volumes. Chicago’s RLTO requires specific disclosures and provides tenants with additional remedies not available under state law, including the right to recover attorney fees for landlord violations.

Illinois Uses 10 Days for Lease Violations
Under 735 ILCS 5/9-210, when a tenant violates a provision of the lease, the landlord must serve a written 10-day notice demanding that the tenant cure the violation or vacate. Unlike some states, Illinois does not provide a shorter period for repeat violations—the 10-day period applies each time. If the tenant cures within 10 days, the landlord cannot proceed with eviction. Chicago landlords must also comply with the RLTO, which requires additional disclosures.

Serving the Notice in Illinois
Proper service is critical in Illinois. The method of delivery determines when the notice period starts running and must be documented for court proceedings.
Personal Service
Hand the notice directly to the tenant. The 10-day period starts the next day. This is the preferred method in Illinois Circuit Court. Use a process server for documentation.
Substitute Service
If the tenant is not available, leave the notice with a person aged 13 or older at the tenant’s residence and mail a copy. Illinois requires both steps for valid substitute service.
Posting and Mailing
If no one is available at the residence, post the notice on the main entrance and mail a copy via certified mail. Add 5 days for mailing under Illinois law.
