Introduction
Do you have an emotional support animal (ESA) that helps with stress, anxiety, or depression?
If you're living in Illinois, you might be wondering:
- “Can my landlord deny my ESA because it’s a pit bull?”
- “Is my large dog too big to live in my apartment legally?”
The good news? Illinois Emotional Support Animal Laws protect your rights.
Let’s explore what the law says about breed and size limits for ESAs—and how an Illinois ESA Letter can help.
What Is an Emotional Support Animal (ESA)?
An Emotional Support Animal is more than just a pet. It offers comfort, love, and stability to people with emotional or mental health conditions such as:
- Anxiety
- Depression
- PTSD
- Panic disorders
Important things to know:
- An ESA is not the same as a service dog (which gets more public access).
- ESAs don’t need special training.
- You do need a valid Illinois ESA Letter from a licensed mental health professional.
This letter shows that you truly need your animal for emotional well-being.
Legal Rights for ESAs in Illinois
In Illinois, your rights as an ESA owner come from federal housing laws—especially the Fair Housing Act (FHA).
Under the law:
- Landlords must allow emotional support animals even in "no-pet" housing.
- They cannot charge pet rent or pet deposits for a verified ESA.
- They must provide reasonable accommodations if you have an Illinois ESA Letter.
Illinois follows these federal guidelines strictly, offering full protection to ESA owners.
Are There Breed or Size Restrictions for ESAs in Illinois?
No! One of the biggest protections under Illinois Emotional Support Animal Laws is this:
Landlords cannot deny your ESA because of its breed or size.
That means:
- A pit bull, German shepherd, or Great Dane can be an ESA.
- Small dogs like Chihuahuas and Shih Tzus are just as valid.
- Even cats, rabbits, and mini pigs can qualify—size doesn’t matter.
Breed bans that apply to regular pets do not apply to ESAs with a valid letter.
And remember—ESA laws override standard pet policies.
Exceptions: When Can a Landlord Say No to an ESA in Illinois?
While your ESA has strong protections, there are a few legal exceptions.
A landlord can deny your ESA if:
- The animal shows aggressive behavior (biting, lunging, etc.)
- It has a history of attacking people or animals
- It causes major property damage
- Your ESA creates a public safety concern
- You do not provide a legitimate ESA letter
So, make sure your ESA is well-behaved and you have the right paperwork.
How to Get an Illinois Emotional Support Animal Letter
You can’t just call your pet an ESA—you need a licensed mental health professional (LMHP) to evaluate you and provide a real Illinois ESA letter.
Steps to get your Illinois ESA Letter:
- Speak to a licensed therapist, psychologist, or psychiatrist.
- They will determine if your mental health qualifies for an ESA.
- If yes, they will provide an official letter stating your need.
Important:
- The letter must be signed, dated, and include the professional’s license number.
- Avoid fake ESA letter scams from shady websites.
- Always verify the license status of the provider.
Tip: Use a reputable telehealth service if you can’t visit in person.
What Illinois Landlords Must Know
Landlords in Illinois must follow the Fair Housing Act and Illinois ESA Laws.
What they can’t do:
- Enforce breed restrictions on ESAs.
- Deny an ESA based on size, appearance, or stereotype.
- Charge pet fees, deposits, or monthly rent for an ESA.
What they can do:
- Ask for a legitimate ESA letter.
- Deny the ESA if it poses a health or safety threat.
- Set basic rules like leash policies or noise limits (as they would for other animals).
Landlords who ignore ESA rights can face legal penalties and housing discrimination lawsuits.
