The Illinois 5-Day Notice to Pay Rent or Quit is the written demand a landlord must serve on a tenant under 735 ILCS 5/9-209 before filing an eviction case for unpaid rent. It tells the tenant to pay the exact rent due within 5 calendar days or surrender possession of the rental unit, and it is the legal trigger that gives the circuit court jurisdiction to hear the eviction complaint.
Getting this notice right matters because Illinois courts dismiss eviction cases every day for tiny defects on the face of the notice. A 2024 Eviction Lab snapshot showed Illinois landlords filed more than 70,000 eviction cases in a single year, and Cook County alone reports that a significant share of those cases get tossed for notice errors that force the landlord to start over.

What the Illinois 5-Day Notice Is and Who Must File It
The Illinois 5-Day Notice to Pay Rent or Quit is a pre-eviction demand letter required by 735 ILCS 5/9-209, the section of the Illinois Eviction Act that governs nonpayment of rent. The notice is not filed in court at the moment of service. Instead, it is delivered to the tenant, and a copy plus a proof-of-service affidavit becomes an exhibit to the eviction complaint the landlord later files in the circuit court.
Any residential landlord in Illinois who wants to evict a tenant for unpaid rent must serve this notice first. That includes individual owners, family LLCs, property management companies acting as agents, public housing authorities, and Section 8 landlords (with extra HUD steps). Commercial landlords use a different track under the lease and 735 ILCS 5/9-210, so this article focuses on residential rentals.
The notice solves one specific problem: it gives the tenant a final, statutory chance to cure the default by paying the full rent within 5 days. If the tenant pays inside the cure window, the landlord must accept the money and the eviction stops. If the tenant does not pay, the landlord may file an Eviction Complaint using the Illinois Supreme Court approved eviction forms.
The clock is short, the rules are technical, and judges read these notices closely. A misspelled address, a wrong rent figure, or a defective signature can sink the entire case. The good news is that once you understand the form, filling it out becomes a repeatable checklist you can use every time.
Before You Start: Documents and Information You Need
Gather every document below before you draft the notice. Each item answers a question the form will ask, and each missing item is a chance to make a mistake that restarts your 5-day clock.
- The signed lease. You need the tenant’s full legal name, the rental address, and the rent amount as written in the lease. If the lease is oral, write down the agreed monthly rent and the move-in date.
- A current rent ledger. Print a ledger that shows every payment, every credit, and every charge through today. The ledger keeps you from including late fees or utilities that the statute does not let you demand in this notice.
- Your ownership or agency proof. Keep a copy of the deed, the recorded property record from the county recorder, or the written management agreement. The tenant or judge can challenge whether you have the legal right to demand rent.
- The exact unit address with apartment number. A unit number left off the notice is one of the top reasons judges dismiss cases.
- The tenant’s full legal name as it appears on the lease. Nicknames and partial names create service problems.
- The names of all adult occupants. You will list “All Other Occupants” on the notice and later on the eviction complaint.
- Any prior notices and emails. Bring partial-payment correspondence in case the tenant claims waiver under cases like Avenaim v. Lubecke.
- A blank Affidavit/Certificate of Service. You will fill this in after delivery to prove how, when, and to whom the notice was served.
- Your government photo ID. Some counties require ID when you e-file the eviction later, and notarized affidavits require ID at the notary.
- Postage and certified-mail forms. If you plan to serve by certified mail, buy the green return-receipt card before you draft the notice so you can mail it the same day you sign it.
If any of these are missing, pause and gather them. A 30-minute delay on the front end is far cheaper than a dismissed case 60 days later.
Where to Get the Form and How to Access It
Illinois does not publish a single statewide mandatory 5-Day Notice form, but several reliable templates track the statute word-for-word. The most trusted free option is the template provided by Illinois Legal Aid Online, which mirrors the language of 735 ILCS 5/9-209. The Cook County Sheriff and the Circuit Court of Cook County also publish eviction-related forms you can adapt.
You can fill the form out three ways. The first is to download the PDF, print it, and complete it in black ink. The second is to type into the PDF on your computer and print the finished document. The third is to use a paid service such as the Illinois Realtors landlord forms library if you are a member.
Whatever template you choose, confirm the document includes four anchor elements: the tenant’s name, the property address, the exact unpaid rent amount, and the statutory cure language giving the tenant 5 days to pay. Without those four anchors, the notice fails on its face.
If you manage property in Chicago, also pull the RLTO Summary attachment because Chicago landlords must attach a current RLTO summary to certain notices and renewal documents. While the RLTO summary is not always required with the 5-day notice itself, attaching it never hurts and protects you from a later RLTO defense.
Step-by-Step: How to Fill Out the Illinois 5-Day Notice Line by Line
This walkthrough follows the order of fields on the standard Illinois Legal Aid Online template. Use the exact field names below on your printed form.
Field 1: “To” Line — Tenant’s Full Legal Name
This field asks who the notice is addressed to. Write the tenant’s full legal name exactly as it appears on the lease, followed by the phrase and All Unknown Occupants.
To answer it, copy the name letter-for-letter from page one of the lease. Use Maria E. Lopez and All Unknown Occupants if the lease says Maria E. Lopez.
A nuance comes up when two tenants signed the lease. List both names joined by and, like Maria E. Lopez and David T. Lopez and All Unknown Occupants. List every signer on the lease, even if only one lives there now.
A common mistake is writing only a first name or a nickname like Dave Lopez when the lease says David Theodore Lopez. The direct consequence is that the eviction summons may not match the notice, and the judge can dismiss the case for inconsistent parties.
A misconception filers carry is that listing Jane Doe covers an unknown roommate. It does not. All Unknown Occupants is the proper catch-all phrase Illinois courts recognize.
Field 2: Rental Property Address
This field asks where the rental unit is located. Write the full street address, unit number, city, county, and ZIP code.
To answer it, write the address the way the United States Postal Service would print it on an envelope. 2245 N. Kedzie Blvd., Apt. 3R, Chicago, Cook County, IL 60647 is correct.
A nuance is multi-unit buildings. If the building has units 1, 2, 3R, and 3F, you must include the specific unit. Without the unit, the notice could refer to four different homes.
The most common mistake is dropping the apartment number. The direct consequence is that the tenant can argue the notice did not identify the premises, and the case gets dismissed under cases applying 735 ILCS 5/9-209.
A misconception is that the lease address alone is enough. Judges want a self-contained notice, so even if the lease describes the unit, the notice must too.
Field 3: Date of the Notice
This field asks for the date you sign and prepare the notice. Use MM/DD/YYYY format, like 05/21/2026.
To answer it, enter the exact day you finalize the notice for service. Do not pre-date or post-date.
A nuance is that the notice date and the service date can differ. If you sign on May 21 but mail it on May 22, your 5-day clock starts from the service date, not the signing date.
The common mistake is using a date earlier than the most recent partial payment. The consequence is the tenant raises a waiver defense and argues the demand was already cured.
A misconception is that the notice is “filed” with the court on the date written. It is not filed at all on this date — it is only delivered to the tenant.
Field 4: Total Rent Due
This field asks for the exact dollar amount of unpaid rent through the date of the notice. Write the figure with a dollar sign and two decimals, like $2,400.00.
To answer it, run your ledger and total only the rent owed. Do not add late fees, utilities, parking, pet fees, or attorney fees, because 735 ILCS 5/9-209 limits the demand to “rent.”
A nuance arises when the lease defines “rent” to include certain charges. Even then, many Illinois judges, especially in Cook County under the RLTO, refuse to count add-ons. The safest move is rent only.
The most common mistake is bundling late fees into the rent total. The consequence is dismissal because the tenant could have cured by paying actual rent but was demanded an inflated figure.
A misconception is that overstating the rent by even a small amount is harmless. Illinois case law, including Avenaim v. Lubecke, treats an overstated demand as a fatal defect.
Field 5: Period the Rent Covers
This field asks which months or weeks the unpaid rent covers. Write the time span clearly, like April 1, 2026 through May 31, 2026.
To answer it, match the period to your ledger entries. If two months are owed, list both months.
A nuance is partial months. If the tenant paid half of April, write April 1, 2026 through May 31, 2026 (April balance $600.00, May balance $1,200.00) so the math is transparent.
A common mistake is skipping the period entirely. The consequence is the judge cannot tell what rent was demanded, and the notice fails for vagueness.
A misconception is that “all rent owed” is specific enough. Illinois courts want exact dates so the tenant knows precisely what to pay to cure.
Field 6: 5-Day Cure Language
This field is the statutory heart of the notice. It tells the tenant that unless the full rent is paid within 5 days after service, the landlord will terminate the lease and seek possession.
To answer it, use the safe-harbor wording from the statute: Unless payment of said rent is made within five (5) days after service of this notice, your lease will be terminated. Do not paraphrase.
A nuance is the counting of the 5 days. The day of service does not count, weekends count, and the cure deadline ends at midnight on day 5 under 5 ILCS 70/1.11.
The most common mistake is writing five business days instead of five days. The consequence is the notice changes the statutory clock and gets struck.
A misconception is that you can shorten the period if the lease says so. You cannot. The 5-day floor is statutory.
Field 7: Address Where Rent May Be Paid
This field asks where the tenant must deliver the cure payment. Write a street address, not just a P.O. Box, plus accepted payment methods if any.
To answer it, list the landlord’s or agent’s street address with hours of acceptance, like Pay at 1100 W. Diversey Pkwy., Suite 200, Chicago, IL 60614, Mon–Fri 9 a.m.–5 p.m.
A nuance is online payment portals. You can list a portal as an additional method, but you must still give a physical address so a tenant without internet can pay.
A common mistake is listing only a P.O. Box. The consequence under Chicago RLTO §5-12-130 is the tenant can argue payment was impossible, and the cure clock is tolled.
A misconception is that “any branch of my bank” is acceptable. Courts want a specific address tied to the landlord, not the tenant’s bank.
Field 8: Landlord or Agent Signature
This field asks for the signature of the landlord or the landlord’s authorized agent. Sign in blue or black ink directly on the notice.
To answer it, the human signing must either own the property or have written authority to act for the owner. Print the signer’s name and title under the signature, like Carlos Mendez, Managing Member, Mendez Holdings LLC.
A nuance is corporate landlords. An LLC cannot sign — a human must sign for the LLC and identify the role.
The common mistake is having a maintenance worker or unrelated relative sign. The consequence is the notice is unauthorized and void.
A misconception is that an electronic signature is always fine. Many Illinois judges still prefer wet-ink signatures on pre-eviction notices, especially in suburban Cook County, so use ink when you can.
Field 9: Landlord or Agent Contact Information
This field asks for the printed name, mailing address, and phone number of the signer. Write each item legibly under the signature block.
To answer it, list a real, monitored phone number and a mailing address that matches the address where rent may be paid.
A nuance is property managers. If a manager signs, list the manager’s company and the owner’s name, like Acme Property Management, Inc., as agent for 2245 Kedzie LLC.
A common mistake is using a disconnected number or a stale address. The consequence is the tenant claims they tried to cure and could not reach you.
A misconception is that contact info is optional. It is not — courts treat the absence of contact info as a sign of an unverifiable demand.
Field 10: Affidavit or Certificate of Service
This field is completed after the notice is delivered. It tells the court how, when, and to whom the notice was served, as required by 735 ILCS 5/9-211.
To answer it, write the date and time of service, the method (personal, substitute, posting, or certified mail), the name of the person served if any, and your signature under penalty of perjury.
A nuance is substitute service. If you handed the notice to a person 13 or older residing on the premises, name that person and note their approximate age.
A common mistake is filling in the affidavit before delivery. The consequence is the affidavit is false on its face, and the case is dismissed or sanctioned.
A misconception is that a text message screenshot is proof of service. It is not. Texting a copy of the notice does not satisfy 735 ILCS 5/9-211.
Three Filled-Out Examples Using Real Scenarios
Below are three named landlords filling out the same form with different facts. Each scenario uses a 2-column table to show what the landlord enters in each major section.
Scenario 1: Carlos in Chicago Under the RLTO
Carlos owns a 4-flat in Logan Square. His tenant, Maria Lopez, owes April and May rent at $1,200 a month. Chicago RLTO applies because the building has fewer than 6 units but Carlos does not live there.
| Form Section | What Carlos Enters |
|---|---|
| To Line | Maria E. Lopez and All Unknown Occupants |
| Property Address | 2245 N. Kedzie Blvd., Apt. 3R, Chicago, Cook County, IL 60647 |
| Date of Notice | 05/21/2026 |
| Total Rent Due | $2,400.00 |
| Period Covered | April 1, 2026 through May 31, 2026 |
| 5-Day Cure Language | Verbatim statutory wording from 735 ILCS 5/9-209 |
| Address for Payment | 1100 W. Diversey Pkwy., Suite 200, Chicago, IL 60614 |
| Landlord Signature | Carlos Mendez, Managing Member, Mendez Holdings LLC |
| Service Method | Personal service on Maria at 6:42 p.m. on 05/21/2026 |
Scenario 2: Janet in Suburban Cook County With a Partial Payment
Janet owns a single-family rental in Oak Park. Her tenant, Marcus Greene, owes $1,800 but paid $400 last week. The Cook County RTLO covers the unit.
| Form Section | What Janet Enters |
|---|---|
| To Line | Marcus A. Greene and All Unknown Occupants |
| Property Address | 812 S. Humphrey Ave., Oak Park, Cook County, IL 60304 |
| Date of Notice | 05/21/2026 |
| Total Rent Due | $1,400.00 (after crediting the $400 partial) |
| Period Covered | May 1, 2026 through May 31, 2026 |
| 5-Day Cure Language | Statutory wording verbatim |
| Address for Payment | PO Box 211 plus 305 Lake St., Oak Park, IL 60302 |
| Landlord Signature | Janet R. Whitfield, Owner |
| Service Method | Certified mail with return receipt requested |
Janet credits the partial payment because failing to credit it would inflate the demand and trigger dismissal under the Cook County RTLO.
Scenario 3: Aisha Downstate With a Section 8 Tenant
Aisha owns a duplex in Champaign and rents to Tasha Brooks under a Housing Choice Voucher. Tasha owes only her tenant share of $250 for May. HUD requires Aisha to coordinate with the local Public Housing Authority.
| Form Section | What Aisha Enters |
|---|---|
| To Line | Tasha L. Brooks and All Unknown Occupants |
| Property Address | 417 W. Green St., Unit B, Champaign, Champaign County, IL 61820 |
| Date of Notice | 05/21/2026 |
| Total Rent Due | $250.00 (tenant share only, not the HAP portion) |
| Period Covered | May 1, 2026 through May 31, 2026 |
| 5-Day Cure Language | Statutory wording verbatim |
| Address for Payment | 912 N. Mattis Ave., Champaign, IL 61821 |
| Landlord Signature | Aisha M. Patel, Owner |
| Service Method | Personal service plus copy mailed to the Housing Authority of Champaign County |
Aisha mails a courtesy copy to the PHA because HUD’s Housing Choice Voucher Program rules require notice coordination on tenant-share defaults.
How to File the Completed Form
Technically, you do not “file” the 5-Day Notice with any court at the moment of service. You serve it on the tenant. Filing only happens later, when you attach the served notice and affidavit of service to your Eviction Complaint in the circuit court.
Personal service. Hand the notice directly to the tenant. This is the strongest method. The fee is zero, and the proof is your signed Affidavit of Service. Processing time is immediate. Keep a photocopy of the signed notice and your affidavit.
Substitute service. Hand the notice to a person 13 or older who resides on the premises and ask them to deliver it. Under 735 ILCS 5/9-211, you must also send a copy by mail. The fee is the price of postage. Keep the mailing receipt as proof.
Certified mail with return receipt requested. Mail the notice to the unit address. The fee is roughly $9 for certified mail with return receipt at current USPS rates. Processing time is 3–7 business days for the green card to come back. Keep the green card and the certified-mail receipt.
Posting on the premises. Posting is allowed only when no one is in actual possession of the unit. Tape the notice to the front door. Photograph the posted notice with a timestamp. Posting is rare and risky for nonpayment cases — use it only after written advice from counsel.
E-filing the later eviction complaint. When you file the Eviction Complaint, use the statewide Odyssey eFileIL portal. Cook County eviction filing fees are set by the Clerk of the Circuit Court of Cook County and run roughly $237–$337 depending on the joint action. DuPage, Lake, and Will counties charge similar amounts. Keep the e-file confirmation as proof of filing.
What Happens After You File
After service, the 5-day cure clock runs. If the tenant pays the full demanded amount within 5 days, the landlord must accept the cure and the eviction is over. Refusing a timely, full cure exposes the landlord to RLTO damages in Chicago and to a complete defense at trial elsewhere.
If the tenant does not cure within 5 days, the landlord may file an Illinois Eviction Complaint attaching the served notice and affidavit. The clerk issues a summons, and the sheriff or a special process server delivers it to the tenant.
The court schedules a first appearance, usually 14–30 days after filing. The tenant may appear and contest the case, raise habitability defenses under 765 ILCS 742/, or move to dismiss for notice defects. If the landlord wins, the judge enters an Order of Possession with a stay of 7–60 days depending on county practice.
After the stay, the sheriff schedules the actual eviction. In Cook County, the Sheriff’s Civil Process Division handles evictions and posts a 24-hour notice on the door before lockout.
Mistakes to Avoid When Filling Out the Form
- Bundling late fees, utilities, or parking into the rent total. The notice fails because the demand exceeds lawful rent.
- Using five business days instead of five days. The notice changes the statutory clock and gets struck.
- Leaving off the apartment number. The premises become legally ambiguous.
- Listing only a P.O. Box for payment. The tenant cannot tender cure, tolling the clock.
- Signing as a maintenance worker or unrelated relative. The notice is unauthorized.
- Pre-dating or post-dating the notice. The dates contradict your ledger and your service affidavit.
- Filling out the affidavit of service before delivery. The affidavit is false and exposes you to sanctions.
- Texting a screenshot of the notice. Text service does not satisfy 735 ILCS 5/9-211.
- Accepting a partial payment after service without a written reservation of rights. You may waive the notice under cases like Avenaim v. Lubecke.
- Filing the eviction complaint on day 5. The cure window runs through midnight of day 5, so file on day 6 or later.
- Forgetting the Chicago RLTO summary when the unit is RLTO-covered. Some judges treat omission as fatal at lease level.
- Writing the wrong tenant name. A nickname mismatch can dismiss the case for inconsistent parties.
Do’s and Don’ts
- Do match the rent amount to your ledger to the penny because judges compare the two side by side.
- Do serve in person whenever possible because personal service is the hardest method to attack.
- Do keep a photocopy of the signed notice before service so you have a clean exhibit later.
- Do mail a backup copy by certified mail even after personal service for a belt-and-suspenders record.
- Do wait the full 5 days plus one before filing the eviction complaint to avoid premature filing.
-
Do consult the Illinois Eviction Help Illinois program if the tenant requests mediation.
-
Don’t include late fees in the demand because Illinois courts strip them and dismiss inflated notices.
- Don’t sign with an electronic signature in counties that prefer wet ink because some judges reject e-signed pre-eviction notices.
- Don’t post the notice on the door if anyone is living in the unit because posting is reserved for vacant units.
- Don’t accept partial payment after service without a written non-waiver letter because partial acceptance can void the notice.
- Don’t serve the notice on a minor because substitute service requires a person 13 or older residing in the unit.
- Don’t rely on email or text alone because 735 ILCS 5/9-211 does not list electronic methods.
Pros and Cons of Filing on Your Own vs. With Help
Many small landlords serve the 5-Day Notice themselves and hire a lawyer only if the tenant fails to cure. Here are the trade-offs.
Pros of filing pro se:
- Saves $300–$700 in attorney fees for the notice stage.
- Speed — you can draft and serve the same day instead of waiting for counsel.
- Direct knowledge of the ledger, which reduces transcription errors.
- Builds your competence for future units if you own multiple properties.
- Some counties, like Champaign, offer self-help eviction packets that walk pro se filers through every step.
Cons of filing pro se:
- Higher dismissal risk because tiny defects sink notices.
- No insulation from RLTO retaliation claims if the tenant counterclaims under Chicago RLTO §5-12-150.
- Time cost of learning the statute, the local rules, and the local judge’s quirks.
- Emotional strain when serving a tenant you know personally.
- No malpractice insurance to fall back on if you make a costly mistake.
Filing by Mail vs. Personal Service
| Factor | Personal Service | Certified Mail |
|---|---|---|
| Cost | Free | About $9 |
| Speed | Immediate | 3–7 business days for green card |
| Strongest in court | Yes | Strong but tenant can deny receipt |
| Requires tenant home | Yes | No |
| Backup recommended | Optional | Always keep receipt |
FAQs
Does the 5-day clock start the day I sign the notice or the day I serve it?
No. The clock starts the day after service, not the day of signing, under 735 ILCS 5/9-211 and Illinois computation rules in 5 ILCS 70/1.11.
Can I include late fees in the rent demand on the 5-Day Notice?
No. Illinois courts limit the demand to “rent” under 735 ILCS 5/9-209, and adding late fees usually voids the notice.
Can I serve the notice by text or email?
No. Illinois law lists personal service, substitute service, certified mail, and posting only — text and email are not authorized.
Do I write the tenant’s nickname or full legal name in the To line?
No. Always use the full legal name from the lease in Field 1 because nicknames create party mismatches with the eviction summons.
Should the rent figure include the current month if it just became due?
Yes. You may include rent due as of the date of the notice, but only rent that is actually past due, not future rent.
Can I list only my P.O. Box as the place to pay rent?
No. Field 7 requires a physical street address so the tenant has a real place to deliver cure payment.
Do I need to attach the lease to the 5-Day Notice?
No. The notice stands alone, but you will attach the lease to the later eviction complaint as an exhibit.
Can my LLC sign the notice in its own name?
No. A human authorized to act for the LLC must sign and identify the role on the signature line.
If the tenant pays on day 5, do I have to accept it?
Yes. A timely full payment cures the default and ends the eviction under 735 ILCS 5/9-209.
Can I accept a partial payment without waiving the notice?
Yes. You may, but only with a written non-waiver letter referencing Avenaim v. Lubecke so the partial payment does not void the notice.
Does Chicago’s RLTO change the 5-day notice itself?
No. The state 5-day clock still controls, but Chicago RLTO §5-12-130 adds tenant rights that affect waiver and acceptance.
Can I file the eviction complaint on day 5 if the tenant has not paid by 9 a.m.?
No. The cure period runs through the end of day 5, so file on day 6 or later to avoid a premature filing dismissal.
Do I need a notary for the Affidavit of Service?
No. Most Illinois counties accept an unnotarized declaration under penalty of perjury, but a notary stamp adds protection if the tenant denies service.
What if my tenant has a Housing Choice Voucher?
Yes, you still serve a 5-Day Notice for the tenant’s share, but you must coordinate with the local PHA and follow HUD voucher rules.
Can I serve the notice on a 14-year-old who answers the door?
Yes. Substitute service allows delivery to a person 13 or older residing in the unit, with a follow-up mailing under 735 ILCS 5/9-211.
