In Illinois, a 5-day notice is the written demand a landlord must serve on a tenant who has fallen behind on rent before an eviction can be filed. Under 735 ILCS 5/9-209, the notice has to state the exact amount of past-due rent and give the tenant at least five days to pay in full; if the tenant pays everything demanded within that window, the lease continues and the landlord cannot proceed.1Illinois General Assembly. 735 ILCS 5/9-209 – Demand for Rent – Eviction Action Miss the deadline, and the landlord can treat the lease as ended and file suit.
What the Notice Has to Say
The 5-day notice is strictly a demand for unpaid rent. It must be in writing, name the exact dollar amount owed, and warn the tenant that the lease will end if full payment is not made within the notice period.
The statute also requires this specific partial-payment warning to appear on the notice:
“Only FULL PAYMENT of the rent demanded in this notice will waive the landlord’s right to terminate the lease under this notice, unless the landlord agrees in writing to continue the lease in exchange for receiving partial payment.”1Illinois General Assembly. 735 ILCS 5/9-209 – Demand for Rent – Eviction Action
A notice that leaves out this language, misstates the amount owed, or pads the total with charges that are not rent, such as late fees or utility surcharges, gives the tenant a real basis to challenge the case. Courts have dismissed evictions built on defective notices.
How the Notice Must Be Delivered
Illinois law recognizes only four ways to serve an eviction-related notice, all set out in 735 ILCS 5/9-211:2Illinois General Assembly. 735 ILCS 5/9-211 – Service of Demand or Notice
- Handing the notice directly to the tenant.
- Leaving it with someone at least 13 years old who lives at the property or is in possession of it.
- Sending it by certified or registered mail with a return receipt requested from the tenant.
- Posting it on the property, but only if no one is in actual possession of the premises.
Posting on the door is a last resort. If anyone is living at the property, posting alone is not valid service. Email and text messages are not on the list, regardless of how the landlord and tenant normally communicate. The statute predates those channels and has not been updated to include them.
Counting the Five Days
The clock starts the day after the notice is properly served, and the tenant has five full calendar days to pay. Weekends and holidays count. A notice served on Monday runs out at the end of the following Saturday.
When the last day falls on a day the landlord’s office is closed or there is no practical way to deliver payment, courts have sometimes given the tenant an extra day. Do not rely on that. Pay as early as possible.
Paying to Stop the Eviction
The most direct response to a valid 5-day notice is to pay every dollar demanded within the five-day window. The Illinois Attorney General’s office lists this cure right as the first defense available to a tenant facing eviction for nonpayment.3Illinois Attorney General. Landlord and Tenant Rights Laws
Partial payment is the trap. Under state law, paying half the amount demanded does not stop anything unless the landlord agrees in writing to accept it as a cure. If the total paid does not equal the full balance by the end of the five days, the notice remains valid and the landlord can still file.1Illinois General Assembly. 735 ILCS 5/9-209 – Demand for Rent – Eviction Action Worse, once the deadline passes, handing the landlord the missed rent does not undo the case. Many tenants scrape the money together late, deliver it, and assume the problem is over. It is not.
Chicago’s Different Rule
Chicago tenants have an extra protection. Under Section 5-12-130(g) of the Chicago Residential Landlord and Tenant Ordinance, if a landlord accepts any partial payment of back rent, that acceptance waives the landlord’s right to collect the remaining unpaid rent described in the notice or sought in the eviction case. That is the opposite of the statewide rule. Chicago landlords who take a partial check without understanding this provision can undermine their own case.
Defenses If the Case Reaches Court
Beyond paying, a tenant can raise several defenses at the eviction hearing:
- Improper notice. The partial-payment language was missing, the amount was wrong, or service did not follow one of the four statutory methods.
- Uninhabitable conditions. A tenant who withheld a reasonable portion of rent because the landlord failed to maintain essential utilities or make necessary repairs after being notified of the problem can raise that as a defense or offset.3Illinois Attorney General. Landlord and Tenant Rights Laws
- Retaliatory eviction. Under the Illinois Landlord Retaliation Act, a landlord cannot evict a tenant for complaining about code violations, requesting repairs, joining a tenants’ organization, or exercising any other legal right. A tenant who proves retaliation can recover up to two months’ rent or double their actual damages, whichever is greater, plus attorney fees.4Illinois General Assembly. 765 ILCS 721 – Landlord Retaliation Act
None of these defenses work if you skip court. Show up. A judge cannot consider defenses you never raise.
What Happens After the Deadline
Once the five days pass without full payment, the landlord can treat the lease as ended and file a forcible entry and detainer action, the formal name for an Illinois eviction case. The complaint can include a claim for all unpaid rent, including pro-rated rent for any period the case is pending.1Illinois General Assembly. 735 ILCS 5/9-209 – Demand for Rent – Eviction Action
The tenant will then be served with a summons and court date. At the hearing, the landlord must prove the notice was properly served, the amount demanded was correct, and the tenant did not pay within the five days. The tenant can raise any of the defenses above. If the tenant does not appear, the court is likely to enter a default judgment for possession, unpaid rent, and court costs. Attorney fees depend on the lease; Illinois has no blanket statute awarding them in eviction cases, but many leases include a fee-shifting clause.
Only the county sheriff can physically remove a tenant who does not leave voluntarily after an order of possession.
When 5 Days Isn’t the Right Notice
The 5-day notice covers unpaid rent only. Other situations require different notices, and a landlord who sends the wrong one can have the case dismissed on that basis alone.
- A 10-day notice is required for lease violations other than nonpayment, such as unauthorized pets, excessive noise, or property damage. The notice must describe the violation, and the tenant has ten days to correct it or vacate.5Illinois General Assembly. 735 ILCS 5/9-210 – Notice to Quit
- A 30-day written notice ends a month-to-month tenancy. Either side can give it, and no reason is required.
- A 7-day notice ends a week-to-week tenancy on the same principle.
Federally subsidized housing has its own rules. Tenants in USDA multi-family housing are entitled to at least 30 days’ written notice before an eviction filing for nonpayment; that requirement remains in effect as of early 2026.6Federal Register. Rescinding 30-Day Notification Requirements Related to Eviction Based on Nonpayment of Rent in Multi-Family Housing Direct Properties HUD published a rule in February 2026 attempting to revoke a parallel 30-day requirement for public housing and project-based rental assistance, but the effective date was indefinitely delayed as of March 2026 pending public comment.7Federal Register. Revocation of the 30-Day Notification Requirement Prior to Termination of Lease for Nonpayment of Rent – Indefinite Delay of Effective Date If you live in subsidized housing and receive a 5-day notice instead of the required 30-day notice, that shorter timeline is likely invalid. Contact a legal aid organization immediately.
Effect on Future Rentals
An eviction judgment does not appear on your credit report; the three major credit bureaus stopped including them. Unpaid rent sent to a collection agency is a different matter and can sit on your credit file for up to seven years.
The bigger concern is tenant screening reports, which are separate from credit reports and pull court records directly. Under the Fair Credit Reporting Act, screening companies can report eviction cases for up to seven years, and an eviction record can lead to higher deposit demands, co-signer requirements, or denials, even when the case was dismissed.8Federal Trade Commission. Tenant Background Checks and Your Rights
Illinois courts can seal residential eviction files when the interests of justice outweigh the public interest in keeping the record open. A court can also seal the file if both parties agree, if no material lease violation occurred, or if the case was dismissed. Sealing does not happen automatically; you or your attorney must ask the court for it.
Free Legal Help
If you receive a 5-day notice and cannot afford an attorney, free legal aid is available across Illinois. LAF (formerly the Legal Assistance Foundation) serves Cook County tenants. Prairie State Legal Services covers 36 counties in northern and central Illinois through eleven regional offices.9Prairie State Legal Services. Pursuing Justice. Restoring Hope. Land of Lincoln Legal Assistance serves much of downstate Illinois. These organizations can evaluate whether the notice is valid, identify defenses, and represent you in court.
Reach out early. The five-day window is short, and waiting until a court summons arrives leaves far less room to negotiate or prepare a defense.
