Illinois Landlord-Tenant Law: 2026 Guide

Illinois landlord-tenant law in plain English

Navigating landlord-tenant law in Illinois requires attention to detail, particularly concerning security deposits, late fees, and lease terminations. For security deposits, Illinois state law does not impose a cap, allowing landlords flexibility. However, landlords operating in Chicago must adhere to a specific limit, capping deposits at one month's rent. This highlights the importance of checking local ordinances in addition to state statutes. Regarding late fees, the state defers to the lease agreement. Landlords have the discretion to define late fee policies, including amounts and grace periods, within their contracts. This emphasizes the critical role of a well-drafted lease in establishing clear expectations for both parties. When it comes to ending a month-to-month tenancy, Illinois law requires landlords to provide tenants with a 30-day notice. This ensures tenants have adequate time to make alternative arrangements. The deposit return window in Illinois is set between 30 and 45 days, giving landlords a specific timeframe to return the security deposit after a tenant vacates the property. Understanding these key provisions helps landlords manage their properties effectively and in compliance with state regulations. Always verify information with the linked statute or a local attorney before acting.
