The Chicago 5-Day Notice: How It Works, the Cure Right, and the Mistakes That Restart the Clock

The 5-Day Notice is the required first step in every Chicago nonpayment eviction, and it's where most cases are won or lost before anyone sees a courtroom. The notice gives the tenant five days to pay the rent owed or face termination of the tenancy. Simple in concept — but the cure rules run longer than five days, and a defective notice sends you back to square one. Here's how it actually works.

What the Notice Does

If rent is unpaid, you serve a written 5-Day Notice demanding the rent and stating your intent to terminate if it isn't paid within five days. If the tenant pays the full amount within those five days, the matter is resolved and the tenancy continues. If they don't, you can file an eviction action in the Circuit Court of Cook County.

The amount demanded has to be accurate — and this is the first trap. If you overstate what's owed (for example, by rolling in an inflated late fee or charges the RLTO doesn't permit in the demand), the notice can be defective. A defective notice gets the eventual eviction dismissed, and you start the entire process over while the tenant stays put. Getting the number exactly right is not optional.

The Cure Right Runs Longer Than Five Days

Here's what surprises landlords: the tenant's ability to cure doesn't end when the five days expire. Under § 5-12-130, a Chicago tenant has a one-time right to pay all unpaid rent — plus the landlord's court filing fees and service costs (but not attorney's fees) — at any point before the court enters an order of possession. If they pay that amount, even after you've filed and you're in court, the eviction stops and they stay.

So the "5 days" in the notice is the window before you can file, not a hard deadline after which the tenant is out. Practically, a paying tenant can reinstate themselves well into the court process. Landlords who expect that nonpayment plus five days equals a guaranteed removal are often surprised when the tenant cures on the courthouse steps.

The Second-Nonpayment Wrinkle

The cure right is generous, but not unlimited. On a second nonpayment within a twelve-month period, the tenant still gets a 5-Day Notice, but the right to cure becomes more limited. The ordinance recognizes a pattern differently than a one-time lapse. This matters for landlords dealing with a chronically late tenant — the second time within a year is a different legal posture than the first.

Service Is Its Own Trap

How you serve the notice matters as much as what it says. The notice has to reach the tenant properly, and in Chicago and Cook County, hand-service is the reliable method. A notice slid under a door without proper service, or sent in a way that can't be proven, gives the tenant grounds to challenge service — and if you can't establish proper service, the case doesn't move forward.

Document everything: the date served, the method, the amount demanded, and how the five days were counted. In a contested case, that record is what carries you.

Where This Sits in the Bigger Process

The 5-Day Notice is step one. After it expires unpaid, you file; then there's a court date, a hearing, a judgment, and — only if you win — a Writ of Possession enforced by the sheriff. The full sequence is in evicting a Chicago tenant for nonpayment, and the connection between fee accuracy and notice validity is covered in the late fee rules. For a specific notice, Dweller IQ can confirm the amount and service approach before you serve it — because a defective 5-Day Notice is the single most common way Chicago nonpayment cases collapse.

Key Takeaways

• A written 5-Day Notice is required to start every Chicago nonpayment eviction; the tenant can cure by paying in full within five days
• The demanded amount must be accurate — an overstated notice (e.g., inflated late fees) can be defective and get the case dismissed
• The cure right runs longer than five days: the tenant can pay all rent plus court filing/service costs any time before the court orders possession
• On a second nonpayment within twelve months, the tenant's cure right becomes more limited
• Service matters — hand-service is the reliable method in Chicago/Cook County, and improper service can sink the case
• A defective 5-Day Notice means starting the entire eviction over while the tenant remains in the unit
