Notice to Vacate in Illinois: Landlord's Guide (2026)

Statewide, 735 ILCS 5/9-210 itself does not impose a cure right. The 10-day notice must describe the character of the default, state that the lessor has elected to terminate the lease, and notify the tenant to quit and deliver up possession within 10 days. Whether the tenant can cure depends on the lease agreement and any local ordinance. Inside Chicago, CRLTO 5-12-130(b) expressly grants tenants a 10-day right to cure material noncompliance. The Cook County RTLO also grants a 10-day cure right for lease violations in covered suburban Cook County units. The right to cure does not extend to alleged criminal conduct.

The federal Servicemembers Civil Relief Act (50 U.S.C. § 3955) lets active-duty servicemembers terminate a residential lease at the lessee's option after entry into military service or receipt of qualifying military orders. Illinois 735 ILCS 5/9-107.10 layers additional protection inside a pending Illinois eviction: the court may, and upon motion shall, stay the proceedings for up to 90 days or adjust the rental obligation when the servicemember's ability to pay is materially affected by military service. Landlords serving notice on a residence occupied by a servicemember should screen for SCRA status before filing the eviction complaint.

Yes, in narrow circumstances. 735 ILCS 5/9-118 authorizes an emergency eviction with no predicate notice where the premises are owned or managed by a housing authority or privately owned and managed and a verified complaint alleges unlawful possession, manufacturing, delivering, using, selling, or trafficking in cannabis, methamphetamine, narcotics, or controlled substances on the premises with the tenant's knowledge and consent. A hearing is scheduled at least 14 days after the complaint is filed. Court stays of the eviction order are capped at 7 days. The statute expressly preserves lawful prescription possession. This is a unconditional pathway: the tenant cannot cure to defeat the action.

An Illinois circuit court will dismiss an eviction action where the pre-suit notice failed to satisfy the statutory content or service requirements. Common defects include understating the rent demanded under 735 ILCS 5/9-209, omitting the description of default required by 735 ILCS 5/9-210, failing to deliver written notice in one of the four service modes listed in 735 ILCS 5/9-211, or filing suit before the full statutory notice period (5, 7, 10, 30, or 60 days) has elapsed. A defective notice forces the landlord to restart the process with a fresh notice, adding weeks to the timeline. Inside Chicago, omitting the CRLTO 5-12-130(g) summary of tenant rights also exposes the landlord to dismissal.

The Illinois Landlord Retaliation Act, effective January 1, 2025 and codified at 765 ILCS 721/1 et seq., replaced and broadened the prior Retaliatory Eviction Act (765 ILCS 720/, repealed by P.A. 103-831). The statute prohibits landlords from terminating or refusing to renew, raising rent, decreasing services, or bringing or threatening a possession suit because the tenant reported building, health, or housing code violations to a government agency or public official, or complained to or sought help from a community organization about code or illegal practices. A rebuttable presumption of retaliation applies if the landlord's adverse action occurs within one year of the tenant's protected activity. Tenants may recover up to two months' rent or two times actual damages, plus attorney's fees. Landlords should document the legitimate, non-retaliatory basis for any termination served close in time to a tenant complaint.

735 ILCS 5/9-121(b) allows a court to seal an eviction case file where the plaintiff's action is sufficiently without basis in fact or law, sealing is clearly in the interests of justice, and those interests are not outweighed by the public's interest in the record. Sealing is mandatory under 9-121(c) for eviction actions brought under 735 ILCS 5/9-207.5 (foreclosure-related occupants), under 735 ILCS 5/15-1701(h)(6), or dismissed under 735 ILCS 5/9-106. The 2021 reform package (Public Act 102-005, signed May 17, 2021) added automatic mandatory sealing of residential eviction cases filed between Illinois's COVID-19 emergency declaration (March 9, 2020) and March 31, 2022. The Motion to Remove Eviction Court File from Public Record is one of the Illinois Supreme Court approved forms.

If the tenant has not paid, cured, or vacated by the end of the statutory notice period, the landlord files an Eviction Complaint in Illinois Circuit Court under the Eviction Article, 735 ILCS 5/9-101 et seq. The Illinois Supreme Court Approved Eviction Complaint (approved 06/2024) and Eviction Summons (approved 05/2023) are accepted in every circuit court. Small-claims procedures are available under Illinois Supreme Court Rule 281 where the rent in controversy does not exceed $10,000. General eviction summons returns are set at least 3 days after service; Cook County eviction summons returns are set at least 7 days after service. Filing fees vary by county and case category. The hearing produces an Eviction Order; the sheriff or other authorized officer enforces the order.
