How much notice Illinois requires to raise the rent
Illinois has no dedicated statewide rent-increase statute. A rent increase on a month-to-month tenancy is treated as a change of lease terms. To accomplish it, the landlord must first terminate the existing tenancy by serving a written 30-day notice under 735 ILCS 5/9-207, with the new terms taking effect at the start of the next rental period. For a fixed-term lease, the rent generally cannot be raised mid-term unless the lease itself contains a provision permitting it.
Rent caps and local limits in Illinois
There is no statewide rent cap in Illinois. The Rent Control Preemption Act, 50 ILCS 825, bars every unit of local government, including home-rule municipalities, from enacting rent control ordinances. This means no city or county in Illinois may legally limit how much a landlord raises rent.
Local governments may, however, impose their own notice requirements that go beyond the state minimum. Chicago’s Fair Notice Ordinance requires approximately 30, 60, or 120 days of advance notice depending on how long the tenant has lived in the unit. Cook County’s Residential Tenant and Landlord Ordinance carries its own notice rules for properties within unincorporated Cook County. These local rules govern timing only; they are not rent caps. Landlords should confirm which local ordinances apply to their specific property before serving any notice.

- Tenant name and rental property address fields
- Current monthly rent amount and new monthly rent amount

How to use it
- Confirm the tenancy type. Determine whether the tenancy is month-to-month or fixed-term, because the rules differ significantly. Do not attempt to raise rent mid-term on a fixed-term lease unless the lease expressly permits it.
- Check local requirements. If the property is located in Chicago, unincorporated Cook County, or another municipality with its own notice ordinance, identify the correct notice period before filling out the template.
- Complete all fields. Enter the current rent, the new rent amount, the effective date, and all identifying information for both the landlord and the tenant. Make sure the effective date falls at the start of a new rental period and allows at least 30 days from the date of service under 735 ILCS 5/9-207, or the longer period required by any applicable local ordinance.
- Serve the notice properly. Deliver the notice in writing by a method you can document, such as certified mail or personal delivery with a written acknowledgment. Keep a copy and proof of delivery for your records.
- Consult an attorney if in doubt. If the situation involves a local ordinance, a fixed-term lease with unusual provisions, or a tenant dispute, review the notice with an attorney licensed in Illinois before serving it.
Frequently asked questions
Can a landlord raise rent in the middle of a lease in Illinois?
Generally, no. Rent under a fixed-term lease is locked in for the lease period unless the lease itself contains a clause that allows mid-term increases. If no such clause exists, the landlord must wait until the lease expires or is renewed to introduce a higher rent amount.
How much notice is required for a rent increase on a month-to-month tenancy?
Illinois requires at least 30 days of written notice under 735 ILCS 5/9-207. The notice must be served before the start of the rental period in which the new rent is to take effect. Some municipalities require more notice, so always check local ordinances.
Is there a limit on how much rent can be raised in Illinois?
No. Illinois has no statewide rent cap, and the Rent Control Preemption Act, 50 ILCS 825, prohibits any local government from imposing one. Landlords may raise rent by any amount, subject only to the required advance notice.
Do Chicago landlords have to follow different rules?
Yes. Chicago’s Fair Notice Ordinance requires longer advance notice depending on tenancy length, ranging from approximately 30 days for shorter tenancies up to approximately 120 days for longer ones. This affects timing, not the amount of the increase. Chicago landlords should review the current text of that ordinance or speak with an attorney before serving a notice.
Does the same 30-day rule apply in Cook County outside Chicago?
Not necessarily. Unincorporated Cook County properties may fall under the Cook County Residential Tenant and Landlord Ordinance, which has its own notice provisions. Landlords with properties in unincorporated Cook County should verify which rules apply to their specific address.
Does this template create a valid legal notice on its own?
The template is an educational starting point. It is designed to reflect Illinois law as researched on July 31, 2026, but laws change and local rules vary. Always have an attorney licensed in Illinois review any notice before serving it to a tenant to confirm it meets all current requirements.
