How to Get a Legitimate ESA Letter in Illinois
A comprehensive guide.

To get a legitimate Emotional Support Animal (ESA) letter in Illinois, you must consult with a licensed mental health professional (LMHP) who can assess your mental or emotional health and determine whether an ESA would help relieve your symptoms. A legitimate ESA letter must be written on the LMHP’s official letterhead, include their license number, the date of issuance, and must clearly state that you have a qualifying mental health condition. The easiest and safest way to get this done is through a trusted online provider like RealESAletter.com, which connects you directly with licensed professionals who understand federal and state ESA regulations. With a valid ESA letter, Illinois residents can live and travel with their support animals without paying extra pet fees under the Fair Housing Act (FHA).

What Are the Legal Requirements for an ESA Letter in Illinois?
In Illinois, a valid ESA letter must be issued by a licensed mental health professional who is authorized to practice in the state. This includes psychologists, licensed clinical social workers, licensed counselors, psychiatrists, and in some cases, primary care physicians. The letter must state that you have a diagnosed mental or emotional disability and that your animal provides therapeutic benefits that ease symptoms of that condition.
The ESA letter should include:
- The LMHP’s name, license number, and state of licensure
- Confirmation of your diagnosis (without needing to reveal specific condition details)
- A statement explaining how the animal helps your condition
- The issuance date and expiration date (typically valid for 12 months)
- Contact information of the LMHP for verification
How Do I Get an ESA Letter in Illinois Online?
Getting an ESA letter online in Illinois is simple if you use a trustworthy service. Here's how the process works:
- Complete a Mental Health Questionnaire – You’ll be asked questions about your mental health and daily challenges.
- Speak with a Licensed Professional – A therapist licensed in Illinois will review your case and may conduct a video or phone call with you.
- Receive Your ESA Letter – If you're approved, the licensed professional will issue your letter, which will be delivered digitally (and optionally by mail).
Services like RealESAletter.com handle this process efficiently and ensure compliance with Illinois and federal ESA laws.
How Can I Tell If an ESA Letter Is Legitimate?
Unfortunately, there are many fake ESA letter scams online. To make sure your letter is legitimate in Illinois, it must:
- Be issued by a licensed mental health professional in your state
- Be written on official letterhead
- Include license details and contact information for verification
- Clearly explain the emotional or mental health need for the ESA
Beware of websites offering “instant approval” or asking no questions about your mental health. These are red flags and can get your letter rejected by landlords or airlines.
What Rights Do ESA Owners Have in Illinois?
If you have a legitimate ESA letter in Illinois, your emotional support animal is protected under the Fair Housing Act (FHA). This means:
- Landlords cannot charge you pet fees or deposits for your ESA
- You can live with your ESA even in “no pet” housing
- Landlords must make reasonable accommodations for your support animal
However, it’s important to note that ESAs are not protected under the Americans with Disabilities Act (ADA), so public places and airlines may not have to accept them the way they do service animals.

Frequently Asked Questions
Can my primary care doctor write me an ESA letter in Illinois?
Yes, if your primary care physician is licensed in Illinois and has knowledge of your mental health condition, they can issue an ESA letter. However, it’s more common (and often more accepted) to get one from a licensed mental health professional.
Do I need to register my emotional support animal in Illinois?
No. There is no government registry for ESAs in Illinois or in the U.S. A valid ESA letter is the only documentation you need.
How long is an ESA letter valid in Illinois?
Most ESA letters are valid for one year from the date of issuance. You’ll need to renew it annually if you want to maintain legal protections.
Can landlords in Illinois reject my ESA letter?
Landlords can only deny your ESA if your animal poses a direct threat to others, causes significant property damage, or if your letter is not legally valid. Otherwise, they are required to accommodate you under the Fair Housing Act.
Can I use the same ESA letter for housing and air travel?
Due to recent changes in airline policies, most U.S. airlines no longer recognize ESAs as service animals. The ESA letter is primarily for housing purposes, not for flights.
Conclusion
If you’re an Illinois resident struggling with anxiety, depression, PTSD, or other emotional or mental health challenges, an ESA could greatly improve your quality of life. Just make sure you get your ESA letter the right way—legally and professionally. Services like RealESAletter.com ensure you’re covered, respected, and protected by the law.
