[IL] Can a tenant sue a landlord for failing to fully remediate mold in a rental property?

Lexi, Chatbot

I'm sorry to hear you're dealing with mold growth; that can be quite concerning. Can you tell me if this mold issue is in a residential or commercial property?

Lexi, Chatbot

Have you already taken any steps to address the mold problem, such as contacting a remediation service or your landlord?

Hello and welcome to our service. My name is Queeneth. I am an attorney with over 8 years of legal experience. I will do my best to assist you today. First I need to ask you a few questions to give you the best answer. (Kindly note that our conversation does not establish an attorney-client relationship.)

Queeneth E. Esq

Can you please let me know which state or country your residential property is located in? Have you noticed any health issues or symptoms that you believe might be related to the mold in your HVAC ducts?

Queeneth E. Esq

Thank you for the feedback. Please allow me some time to prepare a response. I will get back to you shortly.

Thank you for your patience. This could be a serious habitability/mold-remediation issue, especially because you had symptoms, got allergy testing, and the landlord then replaced flooring. But replacing flooring alone may not be enough if the mold source was moisture, subflooring, walls, or HVAC/duct contamination.

In Illinois, the landlord generally must keep the unit fit to live in, make necessary repairs, and comply with state and local health/housing codes. The Illinois Attorney General's tenant-rights fact sheet says landlords must keep the rental unit fit to live in and make necessary repairs. (765 ILCS 705/1)

The HVAC duct issue matters. If mold is in or near the HVAC ducts, vents, air handler, coils, or return system, it can keep spreading spores even after the floor is replaced. The EPA says do not run the HVAC system if you know or suspect it is contaminated with mold, because it can spread mold through the building. The EPA also says that if insulated air ducts become wet or moldy, they generally cannot be effectively cleaned and should be removed and replaced, and that if the condition causing the mold is not corrected, mold will recur.

So your next concern should be: did the landlord fix the moisture source and inspect or remediate the HVAC system, or did they only cover the visible problem by replacing flooring?

Send the landlord a written notice, preferably by email and certified mail, saying:

• You had severe symptoms.
• You obtained allergy testing.
• Mold was suspected or observed in the flooring and/or HVAC/duct area.
• The flooring was replaced, but you need confirmation that the source of moisture was identified and fixed.
• You need a qualified inspection and remediation of the HVAC ducts, air handler, coils, vents, surrounding walls/subfloor, and any remaining affected materials.
• You want copies of any invoices, inspection reports, remediation reports, moisture readings, photos, and contractor notes.

The Illinois Department of Public Health says mold problems often result from building or property-maintenance code violations, and tenants should contact local building or code enforcement officials, because IDPH itself does not inspect rental housing or enforce mold rules.

Your allergy test helps show you had a medical issue and that the landlord may have acted after learning of it. But for a strong claim, you usually need to connect three things: condition, meaning mold or moisture existed in the unit; notice, meaning the landlord knew or should have known; and harm, meaning your symptoms, medical visits, allergy testing, expenses, missed work, or relocation costs were connected to the condition.

The landlord replacing flooring after learning about your testing may help show they took the issue seriously, but it does not automatically prove they fully remediated the problem.

Evidence to preserve. Keep photos and videos of mold, flooring, vents, ducts, water stains, leaks, condensation, and damaged materials. Keep your allergy-test results and doctor records. Keep texts and emails with the landlord. Keep maintenance requests. Keep receipts for medication, air purifiers, hotel stays, cleaning, damaged belongings, or medical visits. Keep the names of contractors who replaced the flooring. Keep any smell or musty-air log, especially when the HVAC runs. Do not rely only on a verbal conversation.

Be careful before withholding rent. Do not stop paying rent or deduct repair costs without legal advice. Illinois allows certain defenses or remedies when a landlord fails to make repairs after notice, but withholding rent can trigger eviction risk if done incorrectly. The Illinois Attorney General notes that tenants may be able to raise repair-related defenses in an eviction, but you should use these remedies carefully.

Your strongest immediate step is written notice, a code enforcement complaint, medical documentation, and a request for HVAC and mold remediation records. If your symptoms are severe or worsen when the HVAC runs, treat that as both a medical issue and a housing-code issue.

Queeneth E. Esq

Since you are thinking about suing, make the email calm, factual, and evidence-preserving. Do not accuse the landlord of poisoning you or hiding mold. Ask for an inspection, records, and remediation.

After you send it, save a PDF or screenshot of the email, delivery confirmation, and any response. If the landlord refuses or ignores it, that helps show notice and failure to inspect or remediate, which matters if you sue.

Anything else you would like me to explain or any additional information you need? Feel free to ask.
