An Illinois unconditional quit notice is the most serious pre-eviction notice a landlord can serve. It tells the tenant that the tenancy is over — not that it will end unless something is paid or fixed, but that the lease has been voided because the premises were used to commit a crime. Illinois puts this remedy in 735 ILCS 5/9-120, part of the eviction article of the Code of Civil Procedure. When a lessee or occupant uses or permits the use of the leased premises, on one or more occasions, for the commission of any act that would be a felony or a Class A misdemeanor under Illinois law, the lease becomes void at the landlord’s option, and the landlord is entitled to recover possession after a five-day written notice to vacate.

The form on this page assembles that notice for you and writes the exact conduct, the governing statute, and the service details into a clean PDF. Because this is a served legal notice that starts a court process, precision matters more than length. Before you serve, confirm you are using the right notice for the conduct: for unpaid rent use the Illinois 5-day pay-or-quit notice instead, and for the full statutory picture review our Illinois eviction notice laws guide. If you are re-renting after a difficult tenancy, tighten the next one at the front door with careful tenant screening.

What an Illinois unconditional quit notice does

Illinois sorts eviction notices by the kind of problem, and the unconditional quit sits at the top of that ladder. For unpaid rent, the landlord serves a five-day pay-or-quit notice, and paying in full stops the eviction. For an ordinary lease violation the tenant can fix — an unauthorized occupant, a pet kept against the lease, a maintenance failure — the landlord serves a ten-day notice and the tenant has ten days to cure. The unconditional quit is different in kind, not just degree. It applies when the premises themselves are used to commit a crime, and it voids the lease at the landlord’s option, giving the tenant no chance to cure and only five days to leave.

That is why the word unconditional matters. A conditional notice says the tenancy continues if the tenant does something — pays, or fixes the problem. An unconditional notice attaches no such condition: the lease is voided because of the criminal use that already occurred. The legal basis is 735 ILCS 5/9-120, which provides that if any lessee or occupant, on one or more occasions, uses or permits the use of the leased premises for the commission of any act that would constitute a felony or a Class A misdemeanor under Illinois law, the lease becomes void at the landlord’s option and the landlord may recover possession. Because the tenant has no chance to cure, the notice must be exact, and the conduct behind it must genuinely rise to the level the statute describes.

What counts as criminal use that voids the lease

The heart of an unconditional quit is the grounds. Under 735 ILCS 5/9-120, the trigger is narrow and specific: a lessee or occupant must use or permit the use of the leased premises, on one or more occasions, for the commission of an act that would be a felony or a Class A misdemeanor under Illinois law. This is not a general “bad behavior” standard. The conduct has to reach the level of a serious criminal offense, and it has to be tied to the use of the premises.

Conduct that commonly supports an unconditional quit under this section includes the following.

• Controlled-substance offenses — using, possessing, selling, delivering, or manufacturing cannabis, methamphetamine, or other controlled substances on the premises.
• Unlawful firearm or weapon offenses committed on the premises.
• Assault, battery, or aggravated battery committed on or near the premises.
• Criminal damage to property or arson affecting the leased premises.
• Theft, burglary, or robbery carried out using the premises.
• Use of the premises for prostitution or a related offense.
• Any other act that would constitute a felony or Class A misdemeanor under Illinois law and that involves the use of the premises.

Two points about this standard are easy to miss. First, the statute reaches acts committed by an occupant, not just the named tenant — if a household member or guest uses the unit to commit a qualifying crime with the tenant’s knowledge and consent, the lease can still be voided. Second, the bar is genuinely criminal. A single loud party or a messy unit is not a felony or Class A misdemeanor, and serving an unconditional quit for that kind of conduct invites dismissal. When the conduct is closer to the line, the safer path is often the 10-day cure-or-quit. Reserve the unconditional quit for conduct that plainly rises to a serious crime.

How it differs from the 5-day and 10-day notices

Choosing the wrong Illinois notice is the most common and most expensive mistake, because the court will not fix a notice mismatch for you — it will dismiss the case and send you back to start over, during which the tenant remains in possession. The Illinois notices answer three different questions.

Notice	Statute	Grounds	Cure period
Unconditional quit	735 ILCS 5/9-120	Felony or Class A misdemeanor committed on the premises (voids the lease)	None — 5-day vacate
5-day pay or quit	735 ILCS 5/9-209	Nonpayment of rent	5 days to pay in full
10-day cure or quit	735 ILCS 5/9-210	Ordinary lease violation (curable)	10 days to fix the problem

The distinction is not about how angry the landlord is; it is about whether the conduct is a serious crime tied to the premises. If the tenant owes rent, the remedy is money, and the five-day pay-or-quit gives the tenant the chance to pay. If the tenant broke a curable term — kept an unauthorized pet, added an occupant, left the yard in disrepair — the remedy is compliance, and the ten-day notice gives the tenant the chance to fix it. Only when the premises are used to commit a felony or Class A misdemeanor does the unconditional quit fit. For nonpayment specifically, do not reach for this form; use the Illinois 5-day pay-or-quit notice built for that purpose, and for a curable violation use the Illinois 10-day cure-or-quit notice.

The emergency path under 735 ILCS 5/9-118

Illinois provides an even faster remedy for the gravest crimes. 735 ILCS 5/9-118, the emergency housing eviction proceeding, lets a landlord move against a tenant for a narrow list of the most serious offenses — drug offenses, murder or attempted murder, kidnapping, arson, aggravated battery, criminal sexual assault, and similar crimes committed on or near the premises. The defining feature of the 9-118 route is that no predicate notice is required. Instead of serving a five-day notice first, the landlord files a verified complaint that sets out the facts and a demand for possession, and the complaint is served at least fourteen days before the hearing. Court stays of the resulting eviction order are capped at seven days.

In practice, most landlords use the 9-120 five-day notice for the broad run of felony and Class A misdemeanor conduct, and reserve the 9-118 emergency proceeding for the specific, severe crimes the statute enumerates. If you believe the conduct fits 9-118, consult an Illinois attorney before filing, because the emergency proceeding has its own strict pleading and proof requirements. The form on this page builds the 9-120 five-day notice; it does not replace the verified complaint an emergency 9-118 case requires.

Serving the notice under 735 ILCS 5/9-211

A perfect notice served the wrong way is still defective, so service deserves as much care as the content. Illinois sets its service rule in 735 ILCS 5/9-211, and that rule — not California’s methods and not any add-days-for-mail convention from another state — is what governs here. Under § 9-211, a demand may be made or notice served in one of these ways: by delivering a copy to the tenant; by leaving a copy with a person aged 13 or older residing on or in possession of the premises; by sending a copy to the tenant by certified or registered mail with a return receipt; or, only when no one is in actual possession of the premises, by posting the notice on the premises.

Because those four methods are the entire list, using any other method — regular first-class mail, email, or a text message — risks having the notice ruled invalid and the case dismissed. Many Illinois landlords hand-deliver the unconditional quit and, where the tenant may be avoiding contact, also send it by certified mail to create a clean record. Whatever method you use, document it: note who served the notice, the date and time, the address, and any witness or return-receipt details. That record is what you will show the court.

Filing the eviction action after the five days

The practical advantage of an unconditional quit is speed. Because the lease is voided by the criminal use and there is no cure period to wait out, the landlord may file an eviction action under the Illinois Eviction Act as soon as the tenant fails to vacate within the five-day window. The court sets the matter for a prompt hearing, and for a case brought under 735 ILCS 5/9-120 an eviction order may not be stayed for more than seven days unless all parties agree to a longer period.

At the hearing, the judge decides whether the conduct actually was a felony or Class A misdemeanor committed on the premises and whether the notice and service complied with the statute. This is where your documentation carries the case. Bring the notice, the proof of service, and every piece of evidence that establishes the criminal use — police reports, arrest or charging records, incident reports, dated photographs, and witness statements. If the landlord prevails, the court issues an eviction order, and the sheriff or other lawfully deputized officer enforces it, typically within seven days of entry. Only that officer, acting under the order, may carry out the removal.

How to complete the notice

The form above assembles the notice, but understanding the steps behind it makes the document far more defensible.

1. Confirm the grounds. Make sure the conduct is genuinely a felony or Class A misdemeanor committed on the premises under 735 ILCS 5/9-120. If it is a curable lease violation, use a different notice.
2. Name the parties and premises. List every tenant on the lease and give the full property address and county for court venue.
3. Describe the criminal use specifically. State the exact act, the date, and the location on the premises. Generic language is the notice’s biggest weakness.
4. Set the termination and service details. Enter the service date, the five-day vacate date, and the method of service under 735 ILCS 5/9-211.
5. Generate, sign, and serve. Produce the PDF, sign it, serve the tenant, and keep a dated copy with your proof of service before filing the eviction action.

Keep the signed notice, the proof of service, and the underlying evidence together in one file. Because the case moves quickly, that file is your case, and it is far easier to build at the moment of service than to reconstruct under a tight hearing deadline.

Why a specific description wins

The single most common reason an unconditional quit notice fails is not that the conduct was innocent — it is that the notice described the conduct too vaguely for a judge to find it was a felony or Class A misdemeanor. A notice that says only “the tenant did something illegal” tells the court nothing about which crime occurred or how the premises were involved. A notice that says “on June 12, 2026, the tenant sold a controlled substance from the unit to an undercover officer, resulting in a felony delivery charge under the Illinois Controlled Substances Act” tells the whole story and shows the conduct clearly falls within 735 ILCS 5/9-120.

Specificity does three things at once. It proves the conduct is genuinely a felony or Class A misdemeanor rather than a curable inconvenience. It gives the tenant fair notice of exactly what conduct voided the lease, which is a due-process requirement the court will check. And it forces you to tie the notice to concrete evidence — a date, a location, a documented crime — which is exactly what you will need to prove at the hearing. When you fill out the description field above, write it as though the judge will read it aloud, because in an eviction hearing the judge often does.

Common mistakes that get the case dismissed

Most failed unconditional-quit evictions trace back to a short list of avoidable errors.

Avoiding these errors is mostly a matter of discipline: confirm the grounds, describe the conduct precisely, serve it correctly, and keep the proof. A strong screening process at move-in also reduces how often you face the kind of tenant conduct that leads here in the first place.

Best practices for Illinois landlords

The landlords who use this notice successfully — and rarely have it thrown out — share a handful of habits.

• Reserve it for genuine crime. Felony or Class A misdemeanor use of the premises belongs here; curable violations do not.
• Describe the act precisely. Give the specific crime, the date, and the location, and cite 735 ILCS 5/9-120.
• Serve it correctly. Follow 735 ILCS 5/9-211 — personal delivery, substitute service, or certified/registered mail — and document every detail.
• Build the evidence packet at service. Police records, photos, and witness information should be ready before you file.
• Never self-help. Let the court and the sheriff carry out the removal under an eviction order.
• Screen carefully going forward. Thorough tenant screening reduces how often you face conduct this serious.

These habits compound. A specific notice, correct service, and a ready evidence file turn Illinois’s eviction process into an advantage rather than a trap.
