Illinois Month-to-Month Lease Overview
Illinois month-to-month lease agreements are governed by the Illinois Compiled Statutes (765 ILCS 705 and 765 ILCS 750). Chicago has its own Residential Landlord and Tenant Ordinance (RLTO) that provides additional tenant protections.
Illinois has a split regulatory landscape: state law provides baseline protections, while Chicago's RLTO adds substantially stronger tenant protections within city limits. Cook County also has its own tenant protection ordinance. Landlords and tenants should know which rules apply to their specific location.

Illinois Month-to-Month Termination Notice Requirements
Illinois requires 30 days written notice to terminate a month-to-month tenancy. The notice must be given at least 30 days before the last day of the month in which the tenancy will end.
Important: Written Notice Required
Illinois requires that termination notice be in writing. Verbal notice is generally not sufficient and may not be enforceable in court. Keep a copy of any notice you send or receive, and consider using certified mail or hand-delivery with a witness to prove delivery.
Illinois Rent Increase Notice Periods
Illinois landlords must provide at least 30 days written notice before increasing rent on a month-to-month lease. Chicago has additional requirements including 60 days notice for certain rent increases.
How to Create a Illinois Month-to-Month Lease
Follow these steps to create a legally compliant month-to-month lease agreement for Illinois.
Identify the Parties and Property
Include the full legal names of the landlord and all tenants, the complete rental property address (including unit number), and the date the lease begins. Specify that this is a month-to-month tenancy that automatically renews.
Set the Rent and Payment Terms
State the monthly rent amount, the due date, acceptable payment methods, any grace period, and late fee terms. Under Illinois law, be sure to comply with any state requirements for grace periods and late fee limits.
Document the Security Deposit
Record the security deposit amount, how it will be held, conditions for deductions, and the return timeline. Illinois limits security deposits to 1.5 months and has specific requirements for how and when the deposit must be returned.
Include Notice Requirements
Clearly state the required notice period for termination (30 days in Illinois) and rent increases (30 days). Include how notice must be delivered (certified mail, hand delivery, etc.) and when the notice period begins.
Add House Rules and Sign
Include provisions for pets, guests, noise, parking, maintenance responsibilities, and any other rules. Both landlord and tenant should sign and date the agreement. Provide copies to all parties.
