765 Ill. Comp. Stat. 721 § 20
Rebuttable presumption. In an action by or against the tenant, if within one year before the alleged act of retaliation there is evidence that the retaliation was against the tenant's conduct that is protected under this Act, that evidence creates a rebuttable presumption that the landlord's conduct was retaliatory. The presumption does not arise if the protected tenant activity was initiated after the alleged act of retaliation
Operative Text
Rebuttable presumption. In an action by or against the tenant, if within one year before the alleged act of retaliation there is evidence that the retaliation was against the tenant's conduct that is protected under this Act, that evidence creates a rebuttable presumption that the landlord's conduct was retaliatory. The presumption does not arise if the protected tenant activity was initiated after the alleged act of retaliation.
Under 765 Ill. Comp. Stat. 721 § 20, when a legal action involves an alleged act of landlord retaliation, a rebuttable presumption of retaliation is established if there is evidence that the tenant engaged in protected activity within the year preceding the alleged retaliatory act. This presumption shifts the burden in the proceeding, meaning the landlord's conduct is assumed to be retaliatory unless that assumption is overcome by contrary evidence. Importantly, the presumption does not apply if the tenant's protected activity began only after the alleged retaliation already occurred.
Plain English — not legal advice.
Property owners and managers operating in Illinois should be aware that under 765 Ill. Comp. Stat. 721 § 20, any adverse action taken against a tenant within a year of that tenant engaging in legally protected activity can trigger a legal presumption of retaliation in court proceedings. Compliant operators generally maintain thorough, contemporaneous documentation of the legitimate, non-retaliatory business reasons behind decisions such as rent increases, lease non-renewals, or notices to vacate. Keeping clear records of maintenance requests, lease violations, and operational decisions helps demonstrate that actions were taken for lawful reasons unrelated to any protected tenant conduct.

Under 765 Ill. Comp. Stat. 721 § 20, tenants in Illinois who have engaged in protected activity—such as reporting housing code violations or organizing with other tenants—may benefit from a legal presumption of retaliation if a landlord takes adverse action against them within one year of that protected activity. This presumption can be a meaningful procedural tool in court proceedings, placing the burden on the landlord to show the action was not retaliatory. Tenants who believe they are experiencing retaliation may consider documenting the timeline of their protected activity and the landlord's response, and can explore options such as consulting a tenant-rights organization or raising the presumption as a defense in any legal action brought by or against them.
