765 Ill. Comp. Stat. 721 § 15
Non-retaliatory actions. An action is not retaliatory if the landlord can prove a legitimate, non-retaliatory basis for the action; or the landlord began the action before the tenant engaged in the protected activity.
Source: Legislative text reproduced verbatim
Plain English

Under 765 Ill. Comp. Stat. 721 § 15, not every adverse action a landlord takes against a tenant automatically qualifies as illegal retaliation. The law recognizes two circumstances that can defeat a retaliation claim: the landlord had a genuine, independent reason for the action unrelated to any protected activity, or the landlord initiated the action before the tenant ever engaged in the protected activity. This provision essentially places the burden on the landlord to demonstrate one of these two defenses when a retaliation allegation arises.

For Property Managers

Under 765 Ill. Comp. Stat. 721 § 15, landlords who face retaliation allegations can defend themselves by demonstrating either a legitimate, non-retaliatory reason for the action taken or that the action was already underway before the tenant engaged in any protected activity. Compliant operators generally maintain thorough, contemporaneous documentation—such as lease-violation notices, maintenance records, and dated correspondence—that can substantiate the independent basis for any adverse action. Keeping organized records of when and why any action was initiated is a standard practice that supports a credible defense under this provision.

For Tenants

Section 15 of 765 Ill. Comp. Stat. 721 defines the defenses a landlord may raise to rebut a retaliation claim, which is important context for tenants who believe they have experienced retaliation. If a landlord asserts that an action had a legitimate basis or predated your protected activity, tenants generally have the opportunity to challenge that assertion through available legal channels, such as raising the issue as a defense in an eviction proceeding or filing a complaint with a local housing authority. Tenant-rights organizations in Illinois can help individuals understand how this provision interacts with their specific circumstances and what documentation may be relevant.
