A tenant just slid an ESA letter across your desk, and now their pit bull lives in your no-pets building.
You have questions, and you are right to ask them. An ESA letter landlord request sits exactly where fair housing law gets serious, because one wrong move can turn into a discrimination complaint.
Here is the good news: handling these requests correctly is a simple, repeatable process. This guide walks you through what the law requires, what documentation you can request, and where landlords get into trouble.
How a Landlord Can Verify an ESA Letter
When a tenant claims a disability-related need for an emotional support animal, you are entitled to reliable documentation. The Fair Housing Act allows landlords to verify the request when the disability or the need is not obvious.
What counts as reliable documentation? Under HUD guidance, it means a letter from a licensed health care professional who has a professional relationship with the tenant and knowledge of their condition.
A certificate bought from a website with no real clinical relationship does not meet that bar.
You can ask the tenant to provide the documentation in writing. You can confirm the provider holds a valid license, since licensing status is public information in most states.
Keep the whole exchange in writing, because a paper trail of your process protects you if the request is ever questioned.
What you cannot do is demand the tenant’s specific diagnosis. You cannot call their doctor to interrogate them about their medical history.
You are verifying the letter, not conducting a medical review.
Some requests need no verification at all. If the disability and the disability-related need for the animal are readily apparent, asking for documentation can itself look like discrimination.
When in doubt, grant the request and move on.
What the Fair Housing Act Requires From You
An emotional support animal is not a pet under fair housing law. It is a reasonable accommodation, and your no-pets policy does not override that obligation.
When a tenant makes the request, you must engage in what the law calls an interactive process. That is a plain word for a good-faith conversation: acknowledge the request, ask for any documentation you are entitled to, and respond within a reasonable time.
You can deny the request only in narrow circumstances. The animal poses a direct threat to the health or safety of others that cannot be reduced by other means, or the request would impose an undue financial or administrative burden on your operation.
A generalized fear of a breed is not a direct threat. If the specific animal has a documented history of dangerous behavior, that is different.
Base your decision on the individual animal, never on assumptions about its type.

ESA Letter Landlord Mistakes That Trigger Fair Housing Complaints
The single most common mistake is charging pet deposits, pet rent, or pet fees for an assistance animal. You cannot.
Fees tied to the animal itself are prohibited, full stop.
The second mistake is demanding more documentation than the law allows. Asking for a diagnosis, therapy notes, or records of treatment sessions goes too far and signals a fishing expedition.
The third is delay. Sitting on a request for months is treated by HUD the same as a denial.
Respond promptly, even if your response is a request for the documentation you are allowed to seek.
The fourth is applying breed or weight restrictions to assistance animals. Your insurance policy may grumble, but breed bans do not survive a fair housing challenge when applied to an accommodation request.
The fifth is telling the tenant to rehome the animal or move. Even said casually, it can be read as a threat tied to a disability accommodation, and that is exactly the kind of statement that ends up in a complaint.
Every one of these mistakes is avoidable with a written procedure. Decide in advance how your team handles requests, who reviews the documentation, and how fast you respond.
Consistency is your best defense.
Fees, Deposits, and Breed Restrictions for Assistance Animals
Let us be precise about money. You may not charge a pet deposit, pet rent, or a nonrefundable pet fee because the tenant has an assistance animal.
These charges are considered discrimination under the Fair Housing Act.
You can still hold the tenant responsible for damage the animal causes. If the dog chews through the carpet or the cat destroys the blinds, those repair costs can come out of the security deposit, exactly as with any other tenant-caused damage.
The difference is timing and targeting. Charges after documented damage are fine.
Charges imposed up front simply because an animal is present are not. One is a response to harm, the other is a penalty for the accommodation.
You may require tenants to follow reasonable rules that apply to all residents.
Check your insurance situation before trouble starts. Some policies exclude certain breeds, but you cannot use that exclusion to deny an accommodation.
Talk to your insurer about assistance animal endorsements so coverage and compliance do not collide. Rules vary by state, and a local fair housing office can confirm the details.
For the day-to-day rules that apply once the animal is approved, see our guide to service animal rental rules, which covers the practical policies landlords can enforce.
Documenting the Request the Right Way
Good records turn a risky situation into a routine one. Date-stamp the tenant’s request the day it arrives and log every step you take.
Keep copies of the documentation provided, your verification notes, and your written response to the tenant. If you granted the request, note the date and any conditions, such as compliance with building animal rules.
If you denied the request, write down the specific reason in factual terms. “Denied because pit bulls are aggressive” will not survive scrutiny.
A documented, individualized assessment might.
Never put medical details in your tenant file beyond what is necessary. The letter itself belongs in a restricted file, not taped inside the lease folder where every staff member sees it.
Treat health documentation with the privacy it deserves.
Train anyone who answers tenant calls on the basics. The front-desk employee who says “we do not allow those” has just made a fair housing violation in your name.
A short staff script is one of the cheapest protections a landlord can buy.
Frequently Asked Questions
Can I ask what the tenant’s disability is?
No. You may request documentation that the tenant has a disability-related need for the animal, but you may not demand the diagnosis or details of their condition.
What if the ESA letter came from an online website?
HUD guidance says documentation should come from a health care professional with a real professional relationship with the tenant. A certificate purchased with no clinical relationship is not reliable documentation, and you may ask for better support.
Can I charge a pet deposit for an emotional support animal?
No. Pet deposits, pet rent, and pet fees for assistance animals are prohibited under the Fair Housing Act.
You can still charge for actual damage the animal causes.
Can I enforce a breed restriction against an ESA?
Breed and weight restrictions generally cannot be applied to assistance animals. Decisions must be based on the individual animal’s behavior, not assumptions about its breed.
What should I do if the animal damages the unit?
Document the damage and charge for repairs the same way you would for any tenant-caused damage, including deductions from the security deposit. The tenant is liable for what their animal does, even though you cannot charge fees in advance.
An ESA request is not a confrontation to win. It is a legal process to run correctly, and landlords who run it correctly rarely have problems.
Handle the request promptly, verify only what you are entitled to verify, waive the fees you must waive, and keep clean records.
Before you start the conversation, it also helps to know the fair housing questions landlords cannot ask, so your first questions to the tenant do not cross a line you did not know was there.
