Yes — and in 2026 that matters more than ever
This is the most important thing on this page. On May 22, 2026, HUD narrowed its federal enforcement standard so that it pursues housing complaints only where an animal has been individually trained to perform disability-related tasks. Most emotional support animals are not trained in that sense, so federal administrative backing largely fell away.
Illinois wrote assistance animals into a dedicated statute in 2020 — one of the few states with an ESA-specific housing law, layered on top of the Illinois Human Rights Act. The 2026 federal change matters less here: your accommodation request runs through Illinois law, and the Act's own documentation rules are what a landlord tests your letter against.
Your state-law right to request a reasonable accommodation for a support animal is unchanged.
You may file with Illinois Department of Human Rights, which applies Illinois law — not HUD's enforcement policy.
Your federal private right of action under the Fair Housing Act also remains, with a two-year window.
Illinois law being strong does not make any individual outcome certain. A housing provider may still deny an accommodation where the animal poses a direct threat, would cause substantial damage, or where the property is genuinely exempt. And landlords who follow only federal news may now push back harder than before 2026 — knowing your state rights is what puts you in a position to respond.
What makes a Illinois ESA letter hold up
Illinois sets no statutory mechanics for ESA letters — no waiting period, no prescribed form. That makes credibility the whole game:
A clinician licensed in Illinois
Psychiatrist or other licensed physician, psychologist, LCSW, LPC, LMFT, or psychiatric NP. An out-of-state license is the first challenge raised.
A genuine clinical evaluation
Instant-approval questionnaires are what taught landlords to challenge letters.
Letterhead, license number, signature, date
Ideally issued within the last year.
No diagnosis disclosure
The letter documents a disability-related need; it should not name your condition.
What a Illinois housing provider must do
Both halves of the law below get equal weight — that's the point.
Consider the request — a blanket "no pets" policy is not, by itself, a lawful answer to an accommodation request
Engage, not stonewall — ignoring a properly made request is itself a problem under the framework
Request only appropriate documentation — of the disability-related need where not obvious, never your full medical records or a specific diagnosis
Not charge pet fees or deposits for an approved assistance animal under state law — one of the clearest points of divergence from HUD's post-2026 federal posture
The specific animal poses a direct threat to health or safety that cannot be reduced by another accommodation
The specific animal would cause substantial physical damage to property
The accommodation would impose an undue financial or administrative burden
The property is exempt (commonly owner-occupied buildings ≤4 units, single-family rentals let without a broker)
The documentation is not credible — and in Illinois it is tested against the state's own rules
Making the request
Get statute-compliant documentation
From a clinician licensed in Illinois, after a genuine evaluation.
Put the request in writing
No specific form needed. State that you have a disability, that you're requesting an accommodation to the pet policy, and that a licensed clinician has documented a disability-related need.
Keep everything
Dates, copies, and any response. If this becomes a complaint, the paper trail is the case.
If you're denied
Ask for the reason in writing. Then consider Illinois Department of Human Rights, a local fair-housing organization, or a private FHA claim — your federal claim lasts two years.

Flying with an emotional support animal
Illinois law does not change air travel rules — those are federal. Since January 11, 2021, the Air Carrier Access Act no longer treats emotional support animals as service animals, and airlines are not required to accommodate them. Carriers treat ESAs as pets, subject to standard pet fees and carrier rules.
An ESA letter does not change this. If air travel is the primary need, that's worth discussing with a clinician — it's a different question from housing.
ESA air travel rules →Illinois FAQ
Straight answers, current as of August 24, 2026.
Does Illinois have its own emotional support animal law?
Yes: Assistance Animal Integrity Act, 310 ILCS 120 (eff. Jan 1, 2020); Illinois Human Rights Act. See the sections above for what it requires and provides.
How much did HUD's 2026 change affect Illinois renters?
Less than in most states. Illinois' framework gives you a state-law route that HUD's memo explicitly leaves untouched, enforced by Illinois Department of Human Rights. Your federal private right of action also remains.
Can my Illinois landlord charge pet rent or a deposit for my ESA?
Illinois law addresses this — see the housing sections above. Since May 2026 there is no federal enforcement of fee waivers for untrained ESAs, so the state-law layer is what matters.
Does Illinois have a waiting period for ESA letters?
No statutory waiting period exists in Illinois. What matters is that your letter comes from a clinician licensed in Illinois after a genuine evaluation — that's what any challenge will test.
Are there penalties for faking an ESA in Illinois?
Illinois has no ESA-specific fraud statute, but misrepresenting an animal as a trained service animal can carry consequences under general law, and it destroys credibility in any housing dispute.
Can I take my ESA into stores or restaurants in Illinois?
No. Emotional support animals have no public access rights in Illinois or any state. Shops, restaurants and transit access belong to trained service animals under the ADA.
