Emotional Support Animal (ESA) Letters in Des Plaines, IL

Renting in a city where four homes in five are owned

Des Plaines has 22,537 occupied homes. Only 4,892 of them are rented. That works out to a 21.7% renter share against 32.9% for Illinois as a whole, on the Census Bureau’s 2020–2024 five-year estimates. Roughly four households in five here own the roof over their heads.

The city is also getting slightly smaller: 60,672 residents in 2020, 58,832 in 2024.

Des Plaines sits right up against O’Hare, and the airport shapes local life enough that the City keeps a standing O’Hare Noise Compatibility Commission. That body sits on the City’s short list of boards and commissions, and not one of the eight handles human relations, human rights or fair housing.

For a tenant asking to keep an emotional support animal, that single absence decides almost everything about how the dispute plays out.

The Act protects your animal without ever using the word

Your main tool is the Illinois Human Rights Act, and it has one odd feature worth knowing before you write to your landlord. Search the statute for the word “animal” and you will not find it.

What it says instead lives at 775 ILCS 5/3-102.1(C)(2). It is a civil rights violation to “refuse to make reasonable accommodations in rules, policies, practices, or services, when such accommodations may be necessary to afford such person equal opportunity to use and enjoy a dwelling.”

Now read your lease with that sentence in mind. A no-pets clause is a rule. A weight ceiling is a rule. A line adding a monthly animal charge to your statement is a rule. You are not asking for a favour. You are asking for one rule to bend so that your home works for you the way other people’s homes work for them.

Illinois defines disability generously. 775 ILCS 5/1-103(I)(1) calls it a determinable physical or mental characteristic. For housing, the only extra condition is that it be unrelated to your ability to rent or keep a home. Anxiety, depression and PTSD are mental characteristics.

A neighbouring section that looks perfect and is not

There is a second section tenants find on their own, and it costs them. 775 ILCS 5/3-104.1 is about refusing to rent to a person with a guide, hearing or support dog. Its part (C) bans extra lease charges beyond actual damage the dog does to the premises. Read cold, it looks written for you.

It was not. That section covers a blind person, a hearing impaired person, or a person with a physical disability. If your disability is a mental health condition and you build your letter on 3-104.1, you have handed your landlord a clean way to say no.

Stay with 3-102.1(C)(2). Nothing in the accommodation duty narrows it to physical conditions.

City Hall will send you somewhere else

The City of Des Plaines publishes a fair housing page, and it is worth reading before you need it, because it tells you plainly what the City will not do.

The page names no city office to complain to. It sends residents to the Illinois Department of Human Rights, to HUD at 312-353-7776 extension 2453 or 1-800-765-9372, to Open Communities at 847-501-5760, and to the Lawyers Committee for Better Housing at 312-347-7600. The only law it identifies as the basis for a complaint is the federal Fair Housing Act.

So build your plan around filing outward. Every door that can actually decide your complaint belongs to the county, the state or a nonprofit.

Three clocks start the day you are refused

Your building sits in suburban Cook County, which opens three routes. They close at very different speeds.

The Cook County Commission on Human Rights wants your complaint within 180 days, under county code section 42-34(b)(1)a. Six months feels long until you have spent two of them exchanging polite emails with the office.

The Illinois Department of Human Rights allows one year from when the violation was committed or ended, under 775 ILCS 5/7B-102(A)(1).

Circuit court allows two years, under 775 ILCS 5/10-102(A). Either side may demand a jury, and paragraph (3) means you may sue whether or not you ever filed a charge with the Department.

Put the 180-day date in your calendar the day the refusal lands. It is the one that quietly expires while you are still being reasonable.

And if the landlord starts leaning on you for asking (pressure to drop it, sudden trouble over something unrelated, a threat), that is a violation in its own right under 775 ILCS 5/3-105.1.

Nobody in Illinois caps what a landlord may charge

Illinois sets no ceiling on a security deposit, a pet deposit, or pet rent. No statute, no state agency rule. For an ordinary pet in a Des Plaines rental, the number is simply whatever the landlord writes down.

That missing ceiling does not weaken an assistance animal request, because a ceiling was never what protected you. Charging you for the animal is charging you for the accommodation, and refusing the accommodation is the violation. The fee collapses for the same reason a flat refusal would.

One sentence in the Act says a piece of this out loud. In the modifications paragraph at 775 ILCS 5/3-102.1(C)(1): “The landlord may not increase for persons with a disability any customarily required security deposit.”

Actual damage, paid receipts, and a rule that grew in 2024

An approved animal is not a free pass. Chewed trim, a ruined carpet. Those are yours to pay for.

What Illinois controls is how the landlord takes the money. 765 ILCS 710/1 requires an itemised statement of the damage, backed by paid receipts, within 30 days. The clock starts at the later of two moments: you move out, or your right of possession ends. No statement, and the entire deposit is due back within 45 days. Where a circuit court finds the landlord refused to itemise or acted in bad faith, the award is double the deposit, plus court costs and reasonable attorney’s fees.

That law used to have a hole in it. Its text applied only to properties “containing 5 or more units.” Public Act 103-224 struck those words effective January 1, 2024. Every residential landlord in Illinois now falls inside it. If you rent from an owner with three or four units, a protection arrived for you two years ago that you never had before.

When the owner lives in the same building

775 ILCS 5/3-106 lists exemptions from the Act, and among them are rental in an owner-occupied building of not more than four families, and rooms let inside a private home.

Here is the detail almost everyone skips. That section opens with the words “Nothing contained in Section 3-102 shall prohibit,” and every cross-reference inside it points back at Section 3-102. The accommodation duty is in a different section, 3-102.1, which 3-106 never names.

No Illinois court decision resolving that gap turned up. So treat it as an argument worth putting to a lawyer, not as a result you already own. If the owner downstairs tells you the Act does not touch them, do not simply accept it, and do not assume you have already won.

There is no state list, and no card worth buying

No Illinois agency keeps a list of emotional support animals for you to join. The Human Rights Act mentions no certificate, no vest and no identification card, because none of those things exists in Illinois law. A Des Plaines landlord who bins that printout has done nothing wrong.

What actually moves a request forward is documentation from a licensed professional who has treated you and can explain why the animal is necessary for your condition. That is what turns “I would like to keep my dog” into the kind of request 775 ILCS 5/3-102.1(C)(2) obliges your landlord to engage with.

Your practical help list, since the City does not have one

Four organisations do the work no Des Plaines office does.

Open Communities is the one the City itself names. It is a fair housing nonprofit for the north and northwest suburbs of Cook County, an area that includes Des Plaines, reachable at 847-501-5760. Know its limit before you call: it does not provide legal representation.

The Cook County Commission on Human Rights is where the county complaint goes, and where that 180-day clock is running.

Legal Aid Chicago is a free civil legal services provider, a place to start if you cannot pay for a lawyer.

Cook County Legal Aid for Housing & Debt handles housing and debt matters for Cook County residents.

The City’s fair housing page names one more, the Lawyers Committee for Better Housing, at 312-347-7600.
