The short answer
Yes. Eligible renters in Illinois can request an ESA letter for housing under applicable fair housing laws. Landlords may request reliable written documentation when a disability or the need for an assistance animal is not apparent. They cannot require a specific diagnosis or charge pet deposits and pet rent for an approved assistance animal. An online certificate without a meaningful assessment may not meet Illinois requirements.

What the Assistance Animal Integrity Act says
Illinois law recognizes assistance animals as a possible reasonable accommodation for people with disabilities. Under applicable law, renters may request permission to keep an emotional support animal even when their lease has a no-pets policy.
When documentation is necessary, it should be written by someone with whom you have a therapeutic relationship and explain your disability-related need for the animal. It does not need to disclose your specific diagnosis.
A certificate purchased online without a meaningful assessment may not satisfy these requirements. At GetPetESA, the assessment is reviewed by a clinician before a decision is made about whether a letter is appropriate.
What an Illinois landlord may and may not do
| The housing provider may | The housing provider may not |
|---|---|
| Request appropriate documentation when needed | Demand a specific diagnosis |
| Verify that a letter is authentic | Charge pet rent or an assistance-animal pet deposit |
| Consider legitimate safety concerns about a specific animal | Automatically reject every assistance animal because of a no-pets policy |
| Charge for damage beyond ordinary wear and tear | Require special liability insurance for the animal |
Why Illinois housing protections matter
Federal policy and complaint procedures can change, but Illinois renters should also consider protections under state law. The Assistance Animal Integrity Act references the Illinois Human Rights Act, which addresses reasonable accommodations for people with disabilities.
If a landlord rejects your request, review the reason carefully and keep copies of your request, documentation, and communications. You can contact the Illinois Department of Human Rights to learn about possible housing discrimination complaints.
Chicago apartments, condos, and rental properties
Whether you rent a Chicago apartment, a condo in Naperville, or a home in Champaign, the same state framework may apply. However, the process can differ between private landlords, property management companies, and condominium arrangements.
Submit your ESA letter for housing to the appropriate housing provider and keep the request in writing. If a condo association is involved, ask your landlord how the accommodation request should be submitted. A standard online form may be convenient, but you should not assume it is the only acceptable way to make a request.

Questions people ask
Can an Illinois landlord charge pet rent for my ESA?
Generally, no. Qualifying assistance animals are not subject to pet fees or pet deposits. You may still be responsible for damage caused by your animal.
Does my ESA letter need to come from an Illinois clinician?
The documentation must meet applicable legal requirements and come from a professional with an appropriate therapeutic relationship. A clinician licensed in Illinois can help address questions about professional authorization.
Is there a 30-day waiting period in Illinois?
Illinois does not set a general 30-day waiting period for an ESA letter. However, a meaningful assessment and appropriate therapeutic relationship remain important.
Can my landlord ask for my diagnosis?
Illinois law does not require your documentation to state a specific diagnosis. It should explain the disability-related need for the assistance animal when documentation is required.
Can I take my emotional support animal into stores?
An ESA does not automatically have the public-access rights granted to qualifying service animals. ESA protections primarily relate to housing. Read our ESA vs. service dog guide to understand the difference.
