Can a landlord change the locks to force a tenant out in Illinois?

No. The Forcible Entry and Detainer Act makes self-help eviction unlawful; the tenant may recover possession and damages. 735 ILCS 5/9-101 et seq. In Illinois a tenant may be removed only through the court process, which is set by 735 ILCS 5/9-104, 9-209, 9-106, 9-117; Chicago RLTO § 5-12-130.

Notes

A five-day notice for nonpayment must state the amount due, and payment of that amount in full within the five days ends it as a matter of law.

This is a summary of the published procedure, not legal advice. Courts, local rules and the facts of a tenancy change what applies, and a defect in a notice or a filing can end a case. Have a lawyer review anything before it is served or filed.

How Seayora uses this rule

Seayora does not file, serve or appear in an eviction, and is not anybody’s lawyer. When a tenant has stopped paying, it lays out these steps for the property’s own state and city with the statute beside each one, holds back any step that would come too early, keeps an append-only record of the case — and shows the resident what would end it, legal-aid links included.
