My Tenant Says the Eviction Is Retaliatory. Now What?

It usually arrives as a sentence in an answer filed by a legal aid attorney: "Plaintiff's action is retaliatory." Suddenly your straightforward eviction has a counterclaim attached, a fee-shifting statute behind it, and a tenant who believes (sometimes sincerely, sometimes strategically) that their 311 call in March makes them untouchable in July. Here is the answer up front: a retaliation claim is beatable, but it is beaten with a paper trail, not with indignation. And the smartest time to beat it is before you serve the first notice.

Two overlapping laws govern this in Chicago, and a third in suburban Cook County. Since January 1, 2025, the stakes statewide are higher than most landlords realize.

The Law Changed: Illinois Took Chicago's Rule Statewide

For decades, Illinois' statewide protection was the old Retaliatory Eviction Act, one thin section protecting only complaints to government. That statute was repealed effective January 1, 2025 and replaced by the Landlord Retaliation Act, 765 ILCS 721, which copies Chicago's broad model and applies everywhere in Illinois. If your understanding of retaliation law (or your lease form) predates 2025, it's obsolete. In the city, RLTO § 5-12-150 continues to apply on top of it, and it declares retaliation flatly "against public policy of the City of Chicago."

What Counts as Retaliation

Under RLTO § 5-12-150, and now in near-identical terms statewide, a landlord may not knowingly terminate a tenancy, increase rent, decrease services, bring or threaten to bring a possession lawsuit, or refuse to renew a lease because the tenant has, in good faith:

• Complained of code violations to a government agency, elected representative, or official charged with enforcing building, housing, or health codes;
• Complained about a code violation or an illegal landlord practice to a community organization or the news media;
• Sought help from a community organization or the media to remedy the violation or practice;
• Requested repairs required by code, regulation, or the lease;
• Joined a tenants' union or similar organization;
• Testified in any court or administrative proceeding about the condition of the premises; or
• Exercised any right or remedy provided by law, the catch-all that swallows everything from a security-deposit demand letter to a jury request.

Read that list the way a plaintiff's lawyer does and you'll notice something uncomfortable: an ordinary repair request is protected activity. Nearly every eviction file with a maintenance history contains the raw material for a retaliation defense. That's not a reason to panic; it's a reason to document.

The One-Year Presumption: How the Burden Flips

Here's the mechanism that gives the defense its teeth. If there is evidence of protected tenant activity within one year before the alleged retaliatory act, that evidence creates a rebuttable presumption that your conduct was retaliatory. You now carry the burden of showing otherwise. Two built-in limits matter just as much:

• Sequence saves you. The presumption "shall not arise if the protected tenant activity was initiated after the alleged act of retaliation." The tenant who calls 311 the day after your 5-day notice lands does not get the presumption against that notice. Date-stamps are ammunition; keep them.
• Cause still matters. The prohibition applies "except for violation of a rental agreement or violation of a law or ordinance," and the statewide Act says the action isn't retaliatory if you prove a legitimate, non-retaliatory basis or that the action began before the protected activity. Retaliation law protects complaining tenants; it does not protect non-paying ones.

What It Costs If You Lose

Under § 5-12-150 a tenant who establishes retaliation gets a defense to the eviction itself (you lose possession) and then elects: recover possession (stay) or terminate the lease (leave). In either case, they recover up to two months' rent or twice their actual damages, whichever is greater, plus reasonable attorneys' fees. If they terminate, you also return the security deposit with interest and all prepaid rent. The fee award is the real economics: by the time a retaliation counterclaim is tried, the tenant's legal-aid or private fees can dwarf the two months' rent. That fee exposure, the same one-way ratchet I fight in RLTO defense cases, is why colorable retaliation claims settle for cash-for-keys numbers that would otherwise look irrational.

The Landlord Playbook: Before and After the Claim

Before You Serve Anything

• Sweep twelve months of file. 311 history, inspection records, repair tickets, portal messages, texts, code cases, tenant-union flyers in the lobby. If protected activity exists, assume the presumption attaches and plan for it; don't discover it from the tenant's answer.
• Build the legitimate basis contemporaneously. Rent ledger for a nonpayment case. Dated photos, incident reports, and neighbor complaints for a breach case. For non-renewals and rent increases: building-wide uniformity is the cleanest rebuttal there is: a rent increase applied to every unit on the same schedule is very hard to spin as personal.
• Mind the sequence. If the termination decision predates the complaint, prove it: dated renewal-decision memos, a rehab plan, a listing agreement, board minutes. Under the statewide Act, action begun before the protected activity is a complete answer.
• Don't decrease services mid-dispute. Pulling the parking spot or laundry key from the tenant who reported you is independently prohibited conduct; it manufactures a fresh claim even where the eviction itself is clean.
• Fix what they reported. The best retaliation defense is a repair invoice. It moots the underlying complaint, undercuts the narrative, and if the "complaint" was itself the tenant's own damage, document that; conduct isn't protected when the tenant caused the violation.

After the Defense Is Raised

• Answer the presumption head-on with the rebuttal evidence above. This is a documents fight, and you want to be the party with the folder.
• Check the timeline first: if the only "protected activity" post-dates your notice, move to strike the defense.
• Nonpayment cases remain your strongest ground: rent was due, rent wasn't paid, and the ledger doesn't care about the 311 call. But remember Chicago's one-time right-to-cure rules on rent cases and get the notice right the first time with my free 5-day notice.
• Run the settlement math honestly. A weak retaliation claim still costs motion practice; a strong one carries fee-shifting. Sometimes the business answer is keys for cash, even when you're right.

Suburban note: outside the city, suburban Cook County's RTLO has its own retaliation section with a couple of landlord-favorable refinements: no protection where the code violation was caused by the tenant's own household, and no presumption from complaints filed after a rent-increase notice. Different suburb, different math; call before you serve.

Timeline and Cost

A retaliation defense doesn't change the procedural spine of the case (notice, filing at $389.25 in Cook County, and 45 to 60-plus days to enforcement in Chicago if you win), but it can add discovery and a counterclaim trial, which is exactly when hourly billing gets ugly. My flat fees hold anyway: $1,600 in Chicago, $895 to $1,250 in suburban Cook, $895 in DuPage, $995 in Kane, contested trials and counterclaim defense included.

Frequently Asked Questions

Can I evict a tenant who complained to 311 or the city about my building?

Yes, for a real, provable reason. The law prohibits evicting a tenant because they complained; it doesn't immunize a tenant who stops paying rent or breaches the lease. Both RLTO § 5-12-150 and the statewide Act carve out terminations for violations of the lease or the law. What changes is your practical burden: expect the presumption and bring a documented, tenant-neutral reason a judge can credit.

How long after a tenant complaint is an eviction presumed retaliatory?

One year. Protected activity within the year before your action creates a rebuttable presumption of retaliation. The presumption doesn't arise when the protected activity started only after your notice or lawsuit, which is why date-stamps on notices and complaints decide these fights.

What does a tenant win on a retaliation claim in Chicago?

A defense to the eviction, plus their election of staying (recovering possession) or leaving (terminating the lease), and in either case up to two months' rent or twice actual damages, whichever is greater, plus reasonable attorneys' fees. On termination, the deposit with interest and prepaid rent come back too.

How does a landlord rebut a retaliation presumption?

With contemporaneous evidence of a legitimate, non-retaliatory basis: rent ledgers, dated lease-violation documentation, photographs, building-wide increases or non-renewals applied uniformly, or proof the decision was in motion before the complaint. Under the statewide Act, action begun before the protected activity is a complete answer. Documents win these; reconstructed testimony loses them.
