How eviction works step by step, and what defenses you have at each stage

At a glance

• Governing statute: 735 ILCS 5/9-101

Who this covers — and who it does not

This page covers the eviction process in Illinois for a residential tenancy — the notices a landlord must serve, the timeline, and what you can do at each stage.

It does not cover commercial leases, or mobile home parks where a separate statute applies. Where a city has its own rules, those may differ from the state statute below.

What the statute actually says

735 ILCS 5/9-101 — 禁止以强力进入（forcible entry）；驱逐须经 Forcible Entry and Detainer 诉讼由法院判决，再由治安官执行。

伊利诺伊的驱逐是「司法驱逐」州：9-101 总纲即禁止自力进入，房东不得自行换锁、断水电或搬走物品。任何不经法院的占有取回都违反本款。

Notice periods by grounds

How the process runs, step by step

1. 房东送达书面通知（5/10/30 天） (from 欠租到期 / 违约发生 / 租期届满). 通知类型须与事由对应：欠租 5 天（9-209）、违约 10 天（9-210）、不定期终止 30 天（9-207）。类型错配的通知无效。
2. 通知期满，房东向巡回法院提起 Forcible Entry and Detainer 诉讼 (from 通知送达). 期满前不能起诉；期满后房东向物业所在县巡回法院起诉。
3. 法院判决返还占有，治安官执行 (from 判决作出). 仅治安官可实际执行搬迁。房东不得自行换锁或搬物。Cook 县另有 Early Resolution Program 前置调解环节。

Can the landlord use self-help?

伊利诺伊禁止自力救济。房东不得换锁、断水电、搬走物品或强行进入；占有取回必须经法院判决与治安官执行。

9-101 明确「不得以强力进入」是总纲。芝加哥 RLTO 另将 lockout 列为违法并设三倍损害，但全州层面本款已足以禁止自力救济。

Common landlord claims and how to answer them

Remedies for an illegal eviction

房东违反 765 ILCS 721 以报复方式驱逐的，租客有抗辩并可主张终止租约、返还押金与预付租金、追回占有，及最多 2 个月租金或 2 倍损害（取大）+ 合理律师费。

注意区分：721/10 是报复驱逐的救济。普通 lockout 的侵权救济另由普通法/芝加哥 RLTO 提供，不在本条。

Sources and how to verify them

Every figure on this page comes from the official text or a state court opinion, not from a summary. The table below lists each provision used and the date it was last checked.

Where the official text and a secondary summary disagree, this page follows the official text and says so. Where a provision admits of more than one reading, that is flagged rather than smoothed over.

When you need a lawyer instead of a tool

A self-help guide is the right starting point for understanding your position. Get legal help if:

• You have received an eviction notice — the timeline is now court-driven
• The dispute involves discrimination, unsafe conditions or retaliation
• Your landlord has filed anything in court already
• You are unsure whether a local ordinance changes the state rule

Local legal aid organisations and tenant unions offer free help for qualifying cases. They are independent of this site — we list them because they are the right place to go, not because they link here.
