How Eviction Actually Works in Cook County
1. Rule one: no self-help evictions
A Chicago landlord cannot legally remove you by changing the locks, taking your belongings, shutting off utilities, or simply telling you to leave. Every eviction — regardless of reason — has to go through Cook County court and end in a court order before a sheriff (not the landlord, not a property manager, not a private security guard) can remove you.
2. The notice types
| Notice | Used for | Length |
|---|---|---|
| 5-Day Notice | Nonpayment of rent | 5 days |
| 10-Day Notice | Lease violation (unauthorized occupant, pet, damage, etc.) | 10 days |
| Fair Notice tiers (30/60/120-day) | Ending tenancy without cause, non-renewal, rent increase | 30, 60, or 120 days based on tenancy length |
The 5-day and 10-day notices are unaffected by how long you've lived in the unit. The tiered Fair Notice periods only apply when the landlord isn't citing nonpayment, a lease violation, disturbance of others, or abandonment.
3. The Fair Notice Ordinance tiers
Chicago's Fair Notice Ordinance (Municipal Code 5-12-130) requires longer notice the longer you've lived somewhere:
- Under 6 months: 30 days' notice
- 6 months to 3 years: 60 days' notice
- More than 3 years: 120 days' notice
This applies to ending a tenancy without cause, declining to renew, and raising the rent. If the landlord serves a shorter notice than your tenancy length requires, you generally have the right to stay for the full required period, or pay the prior rent for that period — the defective notice doesn't shorten your time, it usually just starts a longer clock. Owner-occupied buildings of six units or fewer are exempt from these tiers, similar to the general RLTO exemption.

5. What happens in court
- Notice period expires. Only after this can the landlord file.
- Landlord files an eviction case in Cook County court and has you served with a summons and complaint. In Cook County, the summons return date is set at least 7 days after service.
- Court date. You can appear and raise defenses (see below), negotiate, or in some cases request a jury trial.
- Judgment. If the landlord wins, the court issues an eviction order.
- Sheriff enforcement. Only the Cook County Sheriff can physically carry out an eviction order — this is scheduled separately and takes time.
6. Common defenses
- Defective notice — wrong notice type, wrong length, missing required details (full address, amount owed, signature), or served incorrectly.
- Retaliation — if the eviction follows soon after a building code complaint or organizing activity, Chicago law presumes retaliation unless the landlord rebuts it.
- Habitability / conditions — in some nonpayment cases, unresolved serious repair issues can be raised as a defense or offset.
- Partial payment accepted after a 5-day notice — depending on the circumstances, this can be argued to waive the notice, requiring the landlord to start over.
These are general categories, not guarantees — whether any defense applies depends on your specific facts and documentation, which is exactly the kind of thing to bring to an attorney or a court-based legal aid table before your hearing.

8. FAQ
Can my landlord evict me without going to court?
No. Self-help evictions are illegal. A court order is required before a sheriff can remove you.
How much notice does my landlord have to give?
Depends on the reason: 5 days for nonpayment, 10 days for a lease violation, or 30/60/120 days (based on tenancy length) for a no-cause termination, non-renewal, or rent increase.
What if my landlord doesn't give the correct notice period?
You generally get to stay for the full required period, or pay the prior rent for that period, even though a shorter notice was served.
How long does an eviction case take?
Varies with court load and whether the case is contested, but it always runs through filing, a court date, judgment, and separate sheriff enforcement — never a same-day removal.
