Illinois Landlord Retaliation Act: Protected Acts and Remedies

In Illinois, landlord retaliation is illegal. Under the Landlord Retaliation Act (765 ILCS 721), which took effect January 1, 2025, a landlord cannot evict you, refuse to renew your lease, or threaten to remove you because you complained to a government agency about building, health, or safety conditions. If they do, you can raise retaliation as a defense to eviction and sue for up to two months’ rent or twice your actual damages (whichever is greater), plus reasonable attorney fees.¹ Chicago tenants get more: the city’s Residential Landlord and Tenant Ordinance covers a broader range of tenant activities and presumes any adverse action within one year of protected activity is retaliatory.²

What a Landlord Cannot Do

The state statute makes it unlawful for a landlord to dispossess, threaten to dispossess, or attempt to dispossess a tenant in retaliation for protected activity. In plain terms: no eviction filing, no termination notice, no refusal to renew, no lockout, and no threat of any of the above because you complained.¹

Chicago’s ordinance spells out a longer list of prohibited retaliatory actions:

Terminating the tenancy or threatening to terminate it
Increasing rent as punishment
Decreasing services the tenant previously received, such as parking, laundry access, or routine maintenance
Filing or threatening to file an eviction lawsuit
Refusing to renew a lease at the end of its term

The rent increase prohibition deserves attention. Illinois preempts local rent control, so a landlord can generally raise rent freely.³ But in Chicago, a rent hike imposed as punishment for a code complaint is prohibited retaliatory conduct under the RLTO, even though the same increase would be lawful in any other context.² Outside Chicago, no local ordinance addresses retaliatory rent increases, and a tenant facing a suspicious rent hike may have a harder time proving the increase was punishment rather than a business decision.

Which Tenant Activities Are Protected

Under state law, the core protected activity is making a good-faith complaint to a governmental authority about a genuine violation of a building, health, or safety code.⁴ Calling a building inspector about a broken furnace, contacting the health department about rodents, filing a complaint about missing smoke detectors: all protected. Venting on social media or complaining only to the landlord may not be enough to trigger the state-level protection on its own.

Chicago’s RLTO is much wider. It protects tenants who:

Complain to a governmental agency, elected official, community organization, or the news media about code violations or illegal practices
Request repairs from the landlord directly, whether required by code or by the lease
Join or organize a tenant union
Testify in a court or administrative proceeding about housing conditions
Exercise any right or remedy provided by law (a broad catch-all)

The practical difference is real. A Chicago tenant who emails the landlord asking for a leaking faucet to be fixed is protected against retaliation. A downstate tenant who does the same thing, without also involving a government agency, may not be. If you live outside Chicago, check whether your city or village has adopted a local tenant ordinance that expands on the state baseline.²

Proving the Landlord’s Motive

Retaliation cases are usually won or lost on timing and paper. Landlords do not announce their motives, so tenants have to show a pattern: things were fine, I complained, the landlord acted against me.

Chicago tenants get a significant assist. Under the RLTO, if there is evidence that the tenant engaged in protected activity within one year before the landlord’s adverse action, the court presumes the landlord’s conduct was retaliatory.² That flips the burden. Instead of the tenant proving a hidden motive, the landlord has to show a legitimate, non-retaliatory reason: nonpayment of rent, a genuine lease violation, or a business decision made before the tenant complained.

One boundary on the presumption: it does not arise if the protected activity started after the alleged retaliatory act. You cannot receive a termination notice and then file a code complaint to manufacture a retaliation claim.²

The state Landlord Retaliation Act does not create a statewide presumption. If you are outside Chicago, you still need to present evidence connecting the landlord’s action to your protected complaint. Timing is powerful circumstantial evidence: a termination notice two weeks after a health department inspection makes the case largely on its own. But without a statutory presumption, the initial burden stays with you.

What You Can Recover

A tenant who proves retaliation under the state Act has three tracks of relief:

Retaliation as a defense to eviction. If the landlord files an eviction case in retaliation, you can defeat it.
Recovery of possession. If the landlord has already locked you out or displaced you, the court can order the unit restored.
Money damages. Up to two months’ rent or twice actual damages, whichever is greater, plus reasonable attorney fees.

If you decide to terminate the lease instead of staying, the landlord must return all security deposits and prepaid rent.¹

Chicago’s RLTO offers essentially the same remedies structure: up to two months’ rent or twice damages (whichever is greater), attorney fees, and the return of deposits and prepaid rent on termination. Chicago tenants have five years to file suit after the retaliatory act.²

Attorney fees are the piece that makes the whole system work. Retaliation litigation is not cheap, and without fee-shifting, most tenants would swallow the illegal conduct rather than pay a lawyer thousands to fight it. The prospect of paying the tenant’s legal bill also makes retaliation an expensive gamble for the landlord.

Federal Protection When Discrimination Is Also Involved

The Fair Housing Act adds a federal layer that applies statewide. Under 42 U.S.C. § 3617, it is illegal to coerce, intimidate, threaten, or interfere with anyone exercising rights protected by the Fair Housing Act, including the right to be free from discrimination based on race, religion, sex, national origin, familial status, or disability.⁵

This matters when retaliation overlaps with discrimination. If a tenant with a disability asks for a reasonable accommodation and the landlord responds with an eviction filing, that is not only state-law retaliation but a potential federal fair housing violation. Federal claims open the door to additional remedies, including emotional distress damages, potentially unlimited punitive damages in a private civil suit, and attorney fees.

Building Your Case

Documentation is what separates a strong retaliation claim from a losing one. A few practical habits make the difference:

Put every complaint in writing. An email or text to the landlord, or a written complaint to a government agency, creates a timestamp a phone call does not. Save copies of every complaint, every landlord response, and every notice from a housing inspector or health department. If an agency issues a citation, get a copy.

Document the landlord’s response the same way. If rent goes up, save the notice. If a service disappears, photograph the change and record the date. If the landlord threatens eviction in person, send a follow-up email confirming what was said: “I want to confirm that you told me today you would not renew my lease because I contacted the building department.” A contemporaneous record beats memory every time.

Track the timing. Under the Chicago RLTO, protected activity within one year of the adverse action triggers the presumption of retaliation.² Even where the presumption does not apply, the tighter the gap between your complaint and the landlord’s action, the stronger the inference. Ten days between an inspection and a notice to vacate is nearly self-proving.

If you think retaliation is already underway, talk to a tenant rights attorney or a local legal aid organization before signing anything the landlord puts in front of you, especially a lease termination or a settlement offer. The two-months’-rent damages cap, attorney fees, and deposit return are all on the table if you have the evidence.
