How Illinois Renters Can Handle Pest Infestations Legally

Living with pests can threaten both your comfort and health. If pests like cockroaches, bed bugs, or rodents invade your Illinois apartment, you have legal protections and clear steps you can take. Understanding your rights — and your landlord’s duties — under Illinois law ensures your home remains safe and habitable.

Landlord Responsibilities for Pest Control in Illinois

Under the Illinois Residential Tenants’ Right to Repair Act and the Illinois Security Deposit Return Act, landlords must maintain rental units in a habitable condition. Pests are considered a health and safety issue under the implied warranty of habitability found in these regulations. In most cases, it is the landlord’s obligation to address pest issues unless the infestation was caused by the tenant’s actions.

What Counts as an Infestation?

• Animals or insects that harm health (e.g., cockroaches, rats, bed bugs, mice, wasps)
• Pests causing property damage
• Infestations causing unsanitary conditions

Your landlord must remedy infestations that make the apartment unlivable or unsafe.

What To Do If You Find Pests in Your Apartment

If you discover an infestation, take these immediate actions to protect your health and your rights:

• Document the problem: Take clear photos or videos of the pests and affected areas.
• Notify your landlord in writing: Use email or certified mail to create a record.
• Keep records: Save all communications and keep copies of your complaint.

If your landlord does not respond promptly, you may be able to submit an official complaint or even arrange and deduct the cost of pest control, but there are strict legal steps to follow.

Official Forms Illinois Renters Can Use

1. Repair Request/Notice to Landlord (No Official Form Number)

When to use: If you need to inform your landlord about the pest issue in writing. This step is required before taking legal or financial action.

How to use: Draft and send a letter stating the nature of the infestation, the areas affected, and your request for repairs. Keep a copy for your records. Templates and guidance are available from Illinois Legal Aid Online: How to Send a Repair Notice.

2. Chicago Tenants - Request for Building Inspection

When to use: If your landlord does not act, and your rental is in the City of Chicago, file a complaint with the Chicago Department of Buildings.

How to use: Go to the City of Chicago Building Inspections page to request a building inspection by submitting a service request.

3. Landlord and Tenant Complaint Form (Statewide, via Illinois Attorney General)

When to use: After reasonable time has passed and the landlord refuses to address major pest issues.

How to use: The Illinois Attorney General provides an online Landlord and Tenant Complaint Form. Complete and submit digitally. You’ll be asked for your documentation and attempts to resolve the issue.

Who Handles Tenant-Landlord Disputes in Illinois?

The main government body handling disputes over health, safety, and habitability, including pest infestations, is your local Illinois Attorney General's Office. For Chicago residents, the Chicago Residential Landlord and Tenant Ordinance (RLTO) applies. Other municipalities may have local housing departments for building code enforcement.

What If My Landlord Does Not Respond?

If your landlord does not act after you provide written notice:

• Illinois law allows you to make repairs and deduct the costs from your rent if the issue is not resolved within 14 days, but you must follow legal requirements precisely.
• Document all steps, save receipts, and notify your landlord of your intention to use the “repair and deduct” remedy.
• Contact city or state authorities as described above if the problem is severe or remains unresolved.

Pest Infestation Action Steps for Illinois Renters

• Identify and document the pest issue with details and photos.
• Send your landlord a written repair request (keep a copy).
• If not fixed in 14 days, notify landlord you will use "repair and deduct" if allowed under Illinois law.
• For Chicago renters, file a complaint with the City for a building inspection.
• If the problem continues, file a complaint with the Illinois Attorney General.

Following the proper steps helps you avoid legal complications and protects your home.

Frequently Asked Questions about Pest Infestations in Illinois Rentals

1. Can I withhold rent if pests aren’t removed?
   No. Illinois law does not allow renters to withhold rent due to pest problems. Instead, use the “repair and deduct” method if your landlord fails to act, following all proper steps.^[1]
2. Does my landlord have to pay for extermination?
   Generally, yes — unless you caused the infestation through your own actions. Landlords must keep units habitable under Illinois law.
3. Do I need to let my landlord into my unit for pest treatment?
   Yes. Landlords or their contractors need access to the unit to carry out repairs or extermination as required by law. You should coordinate to allow lawful entry with reasonable notice.
4. Can I break my lease if the pest issue is severe?
   Only if the infestation makes the apartment truly uninhabitable and your landlord fails to act after being notified. Always document your steps and seek legal guidance before moving out.
5. Where do I file a complaint if I live outside Chicago?
   Start with the Illinois Attorney General Landlord and Tenant Complaint Form, and check if your local city has a health or building department for additional support.

• Always document pest problems and notify your landlord in writing.
