Medical Proof for Rental Accommodations in Illinois

Renters with disabilities in Illinois have specific rights under state and federal law when requesting accommodations from their landlords. Navigating the documentation process can feel overwhelming, especially if you are unsure what your landlord can legally ask for, and what you are required to provide.

Understanding Disability Accommodation Requests in Illinois

If you have a disability, you can ask your landlord for accommodations (like a service animal or a reserved parking space) that are necessary for equal access to housing. Under the federal Fair Housing Act and the Illinois Human Rights Act1, landlords must consider reasonable requests but may need certain information before approving them.

What Documentation Can a Landlord Ask For?

Landlords in Illinois are allowed to ask for limited documentation when you request a disability-related accommodation, but there are strict rules about what they can (and cannot) require:

  • Proof of disability: If your disability or need for accommodation is not obvious, a landlord can request documentation showing that you have a disability and need the requested accommodation.
  • No specific diagnosis disclosure: Landlords cannot ask for the details of your diagnosis, medical records, or full medical history.
  • Acceptable documentation can usually come from a health care provider, social worker, or caseworker and should confirm that you meet the legal definition of disability and need the accommodation.

You don’t need to provide a specific government form. A letter from a qualified professional is often enough. For example, if you request to keep an emotional support animal, a brief letter from your doctor or therapist explaining your need is sufficient.

Relevant Forms: Disability Accommodation Requests

  • Reasonable Accommodation Request Form: While the State of Illinois does not require a standardized statewide form, many housing providers use their own forms. For state-assisted housing, you may use the HUD Reasonable Accommodation Request Form as a guide.
    Practical example: If a renter uses a wheelchair and needs a ramp, they should complete this form (or a similar form provided by their landlord or property manager), attach a brief note from their healthcare provider, and submit both to the landlord.

If your landlord provides a form, use it. If not, you can write a short letter stating your request and attach professional verification.

Submitting Your Documentation

  • Submit your request in writing, either using your landlord's form or your own letter.
  • Include documentation from an appropriate professional, if your need is not obvious.
  • Keep a copy of all communications for your records.

Who Handles Disputes? Illinois Human Rights Commission

If your landlord rejects your request, delays unreasonably, or asks for excessive medical proof, you can file a complaint with the Illinois Human Rights Commission (IHRC). They enforce state housing rights and can review your case if you believe you have been discriminated against.

Federal complaints can also be filed with the U.S. Department of Housing and Urban Development (HUD).

Illinois Law on Disability and Landlord Requests

The Illinois Human Rights Act and the federal Fair Housing Act outline your right to equal housing without discrimination based on disability. Landlords cannot treat you differently or retaliate for making a reasonable request.2

If your landlord asks for more information than the law allows, you have the right to decline and direct them to state or federal guidance on reasonable accommodations for renters with disabilities.

Frequently Asked Questions

  2. Do I have to use a specific form to request an accommodation?
    No, there is no mandatory state form in Illinois. However, it's best to request in writing using your landlord's preferred form or a letter, with a brief note from your healthcare provider if needed.

    The law requires landlords to respond without "undue delay." There is no set timeframe, but landlords should handle these requests promptly.
