What Do I Need to Know About ESA in Illinois?
Fair Housing Act (FHA)
The Fair Housing Act protects your right to live with your Emotional Support Animal (ESA) in housing that typically doesn't allow pets. With an ESA letter, landlords must make reasonable accommodations for your animal, and they cannot charge you extra pet fees or deposits.
Air Carrier Access Act (ACAA)
The Air Carrier Access Act protects passengers with disabilities. Since 2021, airlines treat ESAs as pets and can no longer fly for free, so pet fees and carrier rules usually apply. Trained service dogs, including PSDs, still fly in the cabin for free.
Americans with Disabilities Act (ADA)
While the ADA primarily covers service animals, it's important to know that ESAs do not have the same public access rights. However, they do have specific protections in housing and, in some cases, air travel. Knowing the differences can help you navigate situations more effectively.

Get Your ESA LetterYour ESA Rights After HUD’s 2026 Update
On May 22, 2026, HUD pulled its older guidance that told landlords to treat ESAs as assistance animals. It now pursues complaints only for animals trained to perform specific tasks. But HUD only changed how it handles ESA complaints. It did not change the law, repeal the Fair Housing Act or cancel your letter. Your ESA letter is still valid, your state still protects you, and a properly issued letter from a licensed provider is still your best protection.
Your ESA letter remains valid if it’s from a licensed provider
Federal housing law hasn’t changed and still covers your ESA
Most states still protect ESAs
Trained service dogs are still covered
Private FHA lawsuits are still available
Existing court rulings on ESAs still apply

Frequently Asked Questions
Start with a quick online assessment at Wellness Wag. We'll match you with an Illinois-licensed mental health professional for your evaluation. Illinois requires providers to establish a therapeutic relationship with you, which happens through our clinical assessment process. With no waiting period required, you can receive your letter quickly once approved, giving you the right to live with your ESA without extra fees.
Not if you have a legitimate ESA letter. Illinois law requires landlords to accommodate your emotional support animal as part of your disability needs. They can ask to see your letter but can't demand diagnosis details or charge pet-related fees. The only exceptions are if your animal poses safety threats or causes property damage that can't be resolved.
The Illinois Assistance Animal Integrity Act took effect January 1, 2020, creating clear rules for ESAs in housing. Providers must establish therapeutic relationships before writing letters, which prevents fraudulent documentation. The law balances tenant rights with landlord protections, you get to live with your ESA free from discrimination, while landlords get immunity from ESA-related injuries. Remember: housing protection only, not workplace or public spaces.
There's no legal expiration, but most landlords want letters dated within the past year. We recommend annual renewals so your documentation stays current and your provider can verify your ongoing therapeutic need. Fresh letters prevent housing disputes and show your ESA remains part of your treatment plan.
Yes. Illinois tenants can still request to live with their ESA as a reasonable accommodation, and a letter from a licensed provider remains valid. HUD only changed how it enforces complaints for untrained ESAs in May 2026, and the Fair Housing Act is unchanged. Illinois housing law now matters more in how your request is handled. See what HUD's policy change means.
Since Illinois has no waiting period, you can get your letter very quickly. Once an Illinois-licensed provider completes your online evaluation and approves you, your letter arrives by email in as little as 24 hours.
