A notice of termination of tenancy in Illinois is the written warning a landlord (or in some cases a tenant) must deliver before a rental arrangement can legally end, and the required length depends entirely on why the tenancy is ending and how it was structured. State law sets the floors: 5 days for unpaid rent, 10 days for other lease violations, 5 days for drug-related activity, and 7, 30, or 60 days for ending a week-to-week, month-to-month, or year-to-year tenancy without cause. Foreclosure triggers a 90-day rule, and Chicago tenants get longer periods tied to how long they’ve lived in the unit. A notice that gets the timing right but the delivery method wrong can still be thrown out in court, so both parts matter.
No-Cause Termination: 7, 30, or 60 Days
When a landlord wants to end a tenancy that has no fixed end date, and no lease violation is involved, the notice period follows the rhythm of the rent.
- A year-to-year tenancy requires at least 60 days’ written notice before the end of the lease year. The notice can be delivered any time within the last four months of the lease year, but it has to land at least 60 days before the year ends.1Illinois General Assembly. Illinois Code 735 ILCS 5/9-205 – Notice to Terminate Tenancy From Year to Year
- A month-to-month tenancy requires 30 days’ written notice from either side.2Illinois General Assembly. Illinois Code 735 ILCS 5/9-207 – Notice to Terminate Tenancy for Less Than a Year
- A week-to-week tenancy requires 7 days’ written notice from either side.2Illinois General Assembly. Illinois Code 735 ILCS 5/9-207 – Notice to Terminate Tenancy for Less Than a Year
None of these notices require a stated reason. A no-cause termination still cannot be motivated by illegal discrimination or by retaliation for a tenant exercising legal rights.
5-Day Notice for Unpaid Rent
If a tenant falls behind on rent, the landlord can serve a written demand giving the tenant at least five days to pay. Pay in full within the window and the lease continues as though nothing happened. Miss the deadline and the landlord can treat the lease as terminated and file for eviction without any further notice.3Illinois General Assembly. Illinois Code 735 ILCS 5/9-209 – Demand for Rent – Eviction Action
One detail trips up landlords who write their own notices: the demand must prominently state that only full payment of the rent demanded will preserve the tenant’s right to stay. Bury that language, or leave it out, and a court can throw out the case.3Illinois General Assembly. Illinois Code 735 ILCS 5/9-209 – Demand for Rent – Eviction Action
Five days is the statewide floor. Local ordinances can set longer periods; Evanston, for example, requires 10 days.4Illinois Legal Aid Online. Dealing with Unpaid Rent A lease can also specify a longer grace period, and the more tenant-friendly deadline controls. Partial payments accepted without a written agreement can complicate the case, so a landlord who intends to pursue eviction should be careful about what they take after serving the notice.
10-Day Notice for Other Lease Violations
When a tenant breaks a lease term other than nonpayment of rent, the landlord can serve a 10-day notice to quit. This is a termination, not an invitation to fix the problem. The notice tells the tenant that the lease is terminated and that they have 10 days to vacate.5Illinois General Assembly. Illinois Code 735 ILCS 5/9-210 – Notice to Quit
Unlike the rent notice, state law does not give the tenant an automatic right to cure. Unauthorized occupants, property damage, or repeated noise violations can send the landlord straight to termination. Individual leases and some local ordinances do provide cure periods for certain violations, so both parties should check the lease and any applicable municipal rules.
The notice must identify the violation clearly enough that the tenant knows what conduct is at issue. A vague reference to a “lease violation” without specifics is the kind of drafting that gets eviction cases dismissed. The landlord should point to the specific lease provision and describe what happened.
5-Day Notice for Drug Activity
p>Illinois runs a separate, faster track for drug activity on the premises. If a tenant uses the property for possessing, manufacturing, selling, or distributing controlled substances, the landlord can void the lease and post a written 5-day notice to vacate. There is no cure period. The notice must state the reason and must use forms provided by the local circuit court clerk.6FindLaw. Illinois Statutes Chapter 740 Civil Liabilities 40/11
If the tenant does not leave within five days, the landlord can file for eviction. The rule applies even when the drug activity was committed by someone other than the leaseholder, as long as the tenant allowed it on the premises.
How to Serve the Notice
A correctly worded notice is worthless if it isn’t delivered by a method Illinois recognizes. When someone is living in the unit, the statute allows exactly three methods:7Illinois General Assembly. Illinois Code 735 ILCS 5/9-211 – Service of Demand or Notice
- Personal delivery to the tenant. This is the cleanest option and gives the clearest proof of receipt.
- Substitute service on any person at least 13 years old who lives on or is in possession of the premises. This covers the situation where the tenant is out but a family member answers the door.
- Certified or registered mail with return receipt requested. The signed receipt is the court-facing evidence that the tenant was notified.
A fourth option, posting the notice on the property, is available only when the unit is completely vacant and no one is in actual possession.7Illinois General Assembly. Illinois Code 735 ILCS 5/9-211 – Service of Demand or Notice
Email, text messages, and voicemail are not recognized service methods. Even if the tenant acknowledges receiving an electronic notice, a court can still dismiss the eviction case. A landlord who wants to send an email as a courtesy should follow up with one of the three statutory methods. Keep the dated copy, the certified mail receipt, or a written log of a personal delivery. That paperwork is often what decides a contested case.
Chicago’s Longer Notice Periods
Chicago’s Residential Landlord and Tenant Ordinance replaces the flat 30-day rule with periods tied to how long the tenant has lived in the unit:
- Less than 6 months: 30 days’ written notice.
- 6 months to 3 years: 60 days’ written notice.
- More than 3 years: 120 days’ written notice.
A landlord who gives less notice than the ordinance requires doesn’t just face a paperwork problem. The tenant can stay until the correct period runs out, which effectively restarts the clock. Chicago also gives tenants their own termination rights when a landlord fails to maintain the property or provide essential services, including a 14-day notice for material noncompliance and a 72-hour notice when essential services are cut off.8American Legal Publishing. Chicago Municipal Code 5-12-110 – Tenant Remedies
Other Illinois cities and counties may have adopted their own landlord-tenant ordinances. Anyone outside Chicago should check whether local rules extend the state defaults.
90-Day Rule After Foreclosure
A new owner who takes control of a residential property through foreclosure cannot use the standard 30-day notice. Illinois requires at least 90 days’ written notice to terminate a bona fide tenancy after foreclosure, whether the lease is week-to-week, month-to-month, or for a fixed term.9Illinois General Assembly. Illinois Code 735 ILCS 5/9-207.5 – Termination of Bona Fide Leases in Residential Real Estate in Foreclosure
Tenants with a valid lease signed before the foreclosure get the strongest protections, but even month-to-month tenants get the 90 days. The new owner can still pursue eviction for lease violations or unpaid rent under the normal rules; the property changing hands alone doesn’t shorten the notice.
A Notice Is Not an Eviction
This is the most misunderstood point in Illinois landlord-tenant law. A termination notice tells the tenant the lease is ending. It does not, by itself, remove anyone. Only a court order can authorize an eviction, and only the county sheriff can physically remove a tenant. A landlord who changes the locks, cuts off utilities, or hauls a tenant’s belongings out without a court order is breaking the law.
If the tenant neither pays nor leaves when the notice period expires, the landlord has to file an eviction lawsuit (a “forcible entry and detainer” action) in circuit court and attach a copy of the notice to the complaint. The tenant can then challenge the notice on procedural grounds, raise other defenses, or try to negotiate a settlement.10Illinois Legal Aid Online. Written Eviction Notices From filing to physical removal typically takes several weeks at minimum, and contested cases run longer.
Defenses a Tenant Can Raise
The most common defense is that the notice itself was defective. Too few days, no description of the violation, missing the required full-payment language in a rent case, or delivery by an unrecognized method are all grounds to dismiss the case. Judges look at these details closely, and a landlord who cut corners often has to start over.
A tenant can also argue that the landlord failed to keep the unit in habitable condition. Illinois law imposes a duty on landlords to maintain rental units in reasonable condition, and a failure to make repairs can be raised as a defense to eviction for unpaid rent or lease violations. A tenant who believes the eviction is retaliation for reporting code violations or exercising a legal right should consult current Illinois law or a local legal aid organization, since the standalone Retaliatory Eviction Act was repealed effective January 1, 2025, under Public Act 103-831 and replaced with updated tenant protections.11Justia.
