Illinois Landlord Repair Duties & Habitability Rights (2026)

What a landlord must fix, and your options when they do not

At a glance

• Core duty: 伊利诺伊通过州最高法院判例（Jack Spring, Inc. v. Little, 1972）在每份住宅租约中默示「适居性保证」：房东须实质符合适用的建筑、住房与健康法规。
• Notice before acting: Right to Repair Act（765 ILCS 742）：租客书面通知（可挂号信）后，房东有 14 天修复期；紧急情况（如无供暖、无自来水）须更快。
• Governing authority: Jack Spring, Inc. v. Little, 50 Ill. 2d 351 (1972)

Who this covers — and who it does not

This page covers the landlord's duty to maintain a habitable home in Illinois, and what you can do when repairs go unmade.

It does not cover commercial leases, or conditions you caused yourself (which are treated differently).

The landlord's duty

伊利诺伊通过州最高法院判例（Jack Spring, Inc. v. Little, 1972）在每份住宅租约中默示「适居性保证」：房东须实质符合适用的建筑、住房与健康法规。

⚠️ 形态提醒：这不是单一成文法条款，而是判例确立的默示保证，适用于 multi-unit dwelling。成文的具体修复救济在 765 ILCS 742（Right to Repair Act）。

Notice and time to cure

Right to Repair Act（765 ILCS 742）：租客书面通知（可挂号信）后，房东有 14 天修复期；紧急情况（如无供暖、无自来水）须更快。

若房东在期限内未修复，租客可自雇有执照、非亲属的专业人员修理，并从租金中扣除，扣除上限为 $500 或半月租金（取低者）。

Your remedies when repairs go unmade

Landlord entry rules

伊利诺伊无全州成文的房东进入通知期限；一般以「合理通知」（司法常引 24 小时）为准，紧急情况无需通知。芝加哥 RLTO 要求 48 小时书面通知。

全州层面靠 quiet enjoyment 与合理标准；芝加哥有更严的 2 天书面通知、限 8:00–20:00 进入的地方规则。

When the duty does not apply

Right to Repair Act 不覆盖租客或其访客造成的损坏；该等修理由租客负责，房东可向其追偿。

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.

Statute	Last verified	Source
Jack Spring, Inc. v. Little, 50 Ill. 2d 351 (1972)	2026-10-16	official text ↗
765 ILCS 742	2026-10-16	official text ↗
Common law; Chicago RLTO § 5-12-050 (local)	2026-10-16	official text ↗

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.
