Illinois service dog laws

Public access for service animals in Illinois is set by 720 ILCS 5/48-8 in the Criminal Code, which runs alongside the ADA. It names psychiatric service animals explicitly and covers dogs and miniature horses that are trained or still being trained. Refusing entry to a person with a service animal, or to a trainer, is a criminal offense rather than just a civil matter.

State law sits on top of the federal Americans with Disabilities Act (ADA). Where the two differ, a handler in Illinois gets whichever rule protects them more. The key points below come from the Illinois statute or agency guidance linked in the sources, and we re-check them when we review this page.

Section 48-8 protects trainers accompanied by a service animal, so a dog in training also has entry rights to public accommodations.
Knowingly denying a handler or trainer access to a public accommodation is a Class C misdemeanor under 720 ILCS 5/48-8(b).
The Illinois Human Rights Act separately bars landlords from refusing to rent to, or charging extra fees to, tenants who use guide, hearing or support dogs.

Service dog public access in Illinois

Under the ADA, a psychiatric service dog (PSD) is a dog individually trained to do work or perform tasks for a person with a mental health disability. Restaurants, stores, hotels, hospitals and other public places in Illinois must let a PSD in with its handler, even where pets are banned.

When it isn't obvious what the dog does, staff may ask only two questions: is the dog required because of a disability, and what work or task has it been trained to perform. They cannot ask for a letter, an ID card, a vest or a demonstration, and they cannot ask about your diagnosis. A business can ask you to remove a dog that is out of control and not brought under control, or that isn't housebroken.

That means a PSD letter is not a public-access pass in Illinois or anywhere else. Its real value is in housing and, for some airlines, as supporting paperwork. No state or federal agency runs a service dog registry, and online registrations or certificates carry no legal weight.

Illinois PSD housing rights

The federal Fair Housing Act and 24 CFR 100.204 require housing providers to make reasonable accommodations for tenants with disabilities, including an exception to a no-pets rule for an assistance animal. In Illinois, housing complaints can also go to the Illinois Department of Human Rights, which enforces the state's fair housing law.

When the disability or the need for the dog isn't obvious, a landlord may ask for reliable information that you have a disability and that the dog helps with it. That is where a letter from a licensed clinician who has evaluated you comes in. Under the 2004 HUD/DOJ Joint Statement, which is still in force, the landlord generally may not ask about the nature or severity of your condition and may not require an extra fee or deposit as a condition of granting the accommodation. You can still be charged for actual damage.

HUD withdrew its 2020 assistance-animal notice (FHEO-2020-01) effective September 17, 2025. Its May 22, 2026 enforcement guidance treats requests for animals individually trained to perform disability-related tasks, which includes psychiatric service dogs, as presumptively reasonable. Untrained emotional support animals are now reviewed case by case. State law may add protections beyond the federal floor.

Flying with a PSD from Illinois

U.S. Department of Transportation rules (14 CFR Part 382) treat a trained psychiatric service dog as a service animal on flights. Airlines may require the DOT Service Animal Air Transportation Form, in which you attest to your dog's health, training and behavior, and a relief attestation for flights of eight hours or more. Airlines may ask for these up to 48 hours before travel if you booked earlier, and may limit you to two service animals.

The DOT form is your own attestation, not a clinician's. Some travelers still carry their PSD letter as background, but airlines cannot demand one under the federal rule. Emotional support animals are treated as pets on U.S. flights.

How to get a PSD letter in Illinois

Book a free slot, then have a 5–10 minute phone or video evaluation with a licensed clinician. If they find you have a mental health disability and that your trained dog helps with it, the letter is issued and you pay $149 for one or two dogs, or $229 for three. If you don't qualify, you pay nothing.

Every letter lists the clinician's name, license type, license number, issuing state and the date. A landlord can check a license through the Illinois Department of Financial and Professional Regulation or the board that issued it. We only evaluate where our clinicians can lawfully practice, and the booking step confirms your state.

A letter doesn't train your dog. Your dog still has to be individually trained to perform tasks for your disability and behave in public; the letter only documents your need.

Illinois service dog misrepresentation

Many states penalize passing off a pet as a service animal; the Illinois points above note any state-specific rule. Only call your dog a service dog if it is trained to perform disability-related tasks for you. If your dog provides comfort just by being there, an emotional support animal letter for housing may fit better than a PSD letter.

Frequently asked questions

Do I need a PSD letter to take my dog into stores in Illinois?

No. Under the ADA, businesses in Illinois can only ask whether the dog is needed for a disability and what task it is trained to do. They cannot require a letter, ID, vest or registration.

Can a Illinois landlord ask for a PSD letter?

If your disability or need for the dog isn't obvious, a housing provider may ask for reliable information about your disability-related need. A letter from a licensed clinician who evaluated you is a common way to provide it.

Can a Illinois landlord charge a pet deposit for my psychiatric service dog?

Under the 2004 HUD/DOJ Joint Statement, a housing provider generally may not require an extra fee or deposit as a condition of granting a reasonable accommodation. You can still be charged for actual damage, and Illinois law may add protections.

Is there a Illinois service dog registry?

No. Neither Illinois nor the federal government runs a registry for psychiatric service dogs, and paid registrations or certificates don't give legal rights.

How much does a PSD letter cost in Illinois?

$149 for one or two dogs, $229 for three. Booking is free and you only pay if the clinician approves your letter.

How long does the evaluation take?

About 5–10 minutes by phone or video with a licensed clinician. If you qualify, the letter is usually issued the same day.

Do I need a letter to fly with my PSD from Illinois?

No. U.S. airlines may require the DOT Service Animal Air Transportation Form, which you complete yourself. They cannot require a clinician's letter for a trained service dog.

What should I do if I'm refused access in Illinois?

Stay calm, explain the two-question rule, and ask for a manager. For housing you can contact the Illinois Department of Human Rights or HUD; for public places you can file a complaint with the U.S. Department of Justice at ADA.gov.
