Common Types of Complaints and Lawsuits Against Landlords

Here are some common complaints people have against landlords: 

• Your landlord refuses to return your security deposit after you move out. 

• The terms under your lease have been breached. For example, your landlord increases the rent before the lease term was over, breaching the terms of the lease agreement.

• Your landlord has breached Illinois’ implied warranty of habitability. Warranty of habitability means that regardless of any contradicting lease term, your landlord is required to keep your unit in a habitable condition at all times. 

• You are being harassed by the landlord. 

• You experienced discrimination based on your race, ethnicity, gender, sexuality, disability, familial status, etc. For example, you were denied renting an apartment due to your gender.

• Your landlord refuses to make necessary repairs to the rental unit as per the lease terms. 

• Your landlord refuses to do anything about excessive noise or other issues you are having with your neighbors.

Contact Your Landlord and Report a Complaint Directly

For some issues, it may be worth speaking to the landlord directly.

If you've never had issues with your rental before but now have complaints about common spaces, security deposit disputes, or other issues, start by sharing your concerns through email or phone. If they ignore your informal requests, consider writing a formal letter, like a demand letter or complaint letter, as this way, you can outline your requests in the letter, and notify your landlord that you will seek further action if the issue is not resolved.

Here are some other reasons why you should consider sending a formal letter to your landlord:

1. Proof that you tried to resolve the problem out of court. If you end up filing a small claims action against your landlord, the judge in your case may ask you at your small claims hearing if you sent your landlord a demand letter before suing. By sending a written demand letter, there is a record of your attempt to settle that you can demonstrate to the judge.

2. You may resolve the problem without going to court. A demand letter signals to your landlord that you are serious about the problem and willing to take action to resolve the problem. They know that it is cheaper to resolve the problem out of court so they may agree to resolve the problem. 

3. Many city or government agencies would like to see that you tried to resolve the problem on your own before filing a complaint. You can provide your formal letter as proof of your efforts.

File a Complaint With the U.S. Department of Housing and Urban Development 

The U.S. Department of Housing and Urban Development (“HUD”) handles complaints against landlords who receive assistance from the federal government. 

HUD is a United States federal agency (HUD is also described as a cabinet department). HUD is responsible for addressing America's housing needs, enforcing fair housing laws, and more. For example, HUD runs the Multifamily Housing Complaint Line, which enables tenants of HUD-insured and -assisted properties to report complaints such as poor maintenance, dangers to health and safety, mismanagement, and fraud.

Below are instructions for how to report a bad landlord to HUD:

• To report a bad landlord to the Multifamily Housing Complaint Line, call toll-free at (800) MULTI-70 (800) 685-8470) / TTY (800) 432-2209.

• Complaints of housing discrimination are handled by the Office of Fair Housing and Equal Opportunity (an office under HUD) at 1-800-669-9777.

If your landlord doesn’t fall under HUD’s jurisdiction, continue reading below. 

File a Complaint With the Appropriate State or City Agency 

You can also file a complaint against a landlord with a local government department in the city or county where the property is located. Below we have provided information on how to report a landlord or apartment complex to a local housing authority, state or city agency, or various rental commissions in Illinois. 

Illinois Department of Human Rights (IDHR): 

The Illinois Department of Human Rights (IDHR) processes landlord complaints and investigates housing discrimination. IDHR receives complaints regarding denial of housing, harassment, unlawful eviction, and other discriminatory matters. You can file your landlord complaint with IDHR online by submitting this form and emailing it to [email protected]. You can also print out the form and mail it to the listed mailing address. 

Illinois Housing Development Authority (IHDA)

The Illinois Housing Development Authority (IHDA) offers a range of services for tenants with landlord complaints.

You can file a complaint in person at the Commission’s office, online, via mail, or by emailing [email protected]. 

File a Complaint With the Better Business Bureau 

The Better Business Bureau (BBB) is a non-profit that serves as an intermediary between landlords and consumers. You will not find an individual landlord on the BBB. The larger the landlord you rented from, the more likely they are to be found on the BBB. 

Reasons why a large landlord would respond to a BBB complaint: 

• If the landlord is accredited with the BBB and they don't respond to a BBB complaint, its accreditation may be revoked, and the complaint becomes part of its BBB profile.

• Landlords know that a BBB rating can be an important determining factor when a prospective renter is making a decision to rent with that landlord.
