Illinois 5-Day Notice for Unpaid Rent
For ordinary Illinois residential nonpayment, the statewide process starts with a written demand giving the tenant at least five days after service to pay the rent demanded before the landlord treats the lease as ended for nonpayment.
- The notice must demand rent and include the required full-payment warning.
- Service must follow an Illinois-authorized method.
- Chicago and Cook County can add local payment and cure protections.
Built around the requirements of 735 ILCS 5/9-209.
What is the Illinois 5-Day Notice?
Section 9-209 creates the statewide demand-for-rent framework. The notice gives the tenant at least five days after service to pay the rent demanded before the landlord relies on nonpayment to terminate the tenancy.
How are the five days calculated?
Illinois uses its general statutory time-computation rule. The tool counts from the day after service and rolls the final day forward when required by Illinois weekend and statutory-holiday rules.
What amount can the notice demand?
The demand should reflect rent that is actually due. The workflow keeps the rent demand focused on the amount supporting the statutory nonpayment path rather than silently folding unrelated charges into rent.
What information does the notice contain?
The Illinois notice identifies the tenant, premises, rent demanded, notice date, and the statutory full-payment warning required by §9-209. The generated document uses the landlord facts entered in the browser.
How can an Illinois notice be served?
Section 9-211 lists statewide service methods. The delivery method is collected in the workflow because service affects whether the notice path is ready and when the period begins.
What happens after the five days expire?
Expiration of the notice does not itself remove the tenant. If the matter remains unresolved, the landlord generally must use the Illinois court process rather than self-help.
Chicago and Cook County overlays
Chicago and Cook County can add local payment, cure, allocation, or waiver rules. The Illinois tool asks where the property is so those overlays can be applied before the notice is generated.

Frequently asked questions
How many days does an Illinois landlord give for unpaid rent?
For ordinary statewide residential nonpayment, §9-209 uses a written demand giving at least five days after service.
Does Chicago use the same 5-Day Notice?
Chicago uses the five-day framework but adds local protections that can materially affect the result, so the property location must be checked.
Can the landlord remove the tenant when the five days expire?
No. Notice expiration is not self-help authority. Possession generally requires the court process.
