Landlords can request an ESA letter from a licensed mental health professional to verify a tenant’s need for an emotional support animal. For service dogs, they can only ask two questions: whether the animal is needed because of a disability, and what task it performs. Landlords cannot ask about specific diagnoses, demand medical records, charge pet fees, or require registration certificates. The May 2026 HUD memo rescinded prior ESA guidance but did not change the Fair Housing Act itself, and state laws remain fully intact.
The rules around what housing evidence can landlords request and what is off limits have never been more confusing. On May 22, 2026, HUD’s Fair Housing and Equal Opportunity office permanently canceled its longstanding guidance on emotional support animals in a single internal memo. That decision threw tenants and landlords alike into uncertainty, even though the Fair Housing Act itself hasn’t changed by a single word.
This guide breaks down every key term and rule you need to understand, whether you’re a tenant with an ESA or service dog trying to protect your rights, or a landlord trying to stay on the right side of the law.
One critical distinction before we start: housing rules operate under the Fair Housing Act (FHA), not the ADA. The ADA governs public access (restaurants, stores, offices). The FHA governs where you live. The documentation rules are different for each, and confusing them is one of the most common mistakes both landlords and tenants make. For a deeper breakdown of the categories, see this guide on service animals vs. ESAs.
If you need an ESA letter for housing, you can get an ESA housing letter through a licensed mental health professional.
Understanding what housing evidence can landlords request starts with knowing the terminology. Each term below includes its definition, how it relates to documentation, and where the legal boundaries sit.
The FHA’s umbrella term for any animal that provides disability-related support in housing. This includes both trained service dogs and untrained emotional support animals. It is broader than the ADA’s definition, which only covers individually trained service dogs. In housing, the question is not whether the animal is trained but whether the tenant has a disability-related need for the animal.
An animal that provides therapeutic benefit to a person with a mental or emotional disability simply through companionship. ESAs do not need to be trained to perform specific tasks. Their protection exists only in housing (under the FHA) and does not extend to restaurants, stores, or other public spaces. When a tenant’s disability is not readily apparent, a landlord may request documentation, but only in the form of an ESA letter.
An animal individually trained to perform specific tasks related to a person’s disability. Examples include guiding a person who is blind, alerting a person who is deaf, or interrupting a psychiatric episode. In housing, service dogs receive FHA protection. In public, they also receive ADA protection. The documentation rules are more restrictive for landlords: if the disability and the animal’s task are obvious, a landlord cannot request any documentation at all.
A service dog specifically trained to perform tasks related to a mental health disability, such as PTSD, severe anxiety, or depression. Tasks might include deep pressure therapy during a panic attack, interrupting self-harm behaviors, or creating physical space in crowds. A PSD has both ADA public-access rights and FHA housing rights. For more on the conditions service dogs address, that breakdown covers common qualifying disabilities.
In housing, a landlord may ask the two standard questions (covered below) if the disability isn’t apparent. They may also request a clinician letter, though this is not always required for PSDs the way it is for ESAs.
The federal law (42 U.S.C. § 3601 et seq.) that prohibits discrimination in housing based on disability, among other protected classes. It requires housing providers to make reasonable accommodations for tenants with disabilities, including modifying no-pet policies to allow assistance animals. The FHA is the primary legal framework governing what evidence landlords can request and what is off limits in housing.
A change to rules, policies, practices, or services that gives a person with a disability equal opportunity to use and enjoy their housing. Allowing an ESA in a no-pet building is the textbook example. The tenant requests the accommodation, provides supporting documentation if needed, and the landlord evaluates it. The landlord does not get to decide whether the disability is “real enough.” They evaluate whether the request is reasonable and whether the documentation supports a disability-related need.
If you need guidance on how to formally submit one, this walkthrough on requesting reasonable accommodation covers the step-by-step process.
The single most important document in this entire topic. An ESA letter is the only document a landlord may request to verify that a tenant has a disability-related need for an emotional support animal. It must come from a licensed mental health professional.
A valid ESA letter must include:
Official letterhead from the licensed mental health professional
The provider’s license number, license type, and issuing state
Confirmation that the provider has an established therapeutic relationship with the tenant
A statement that the tenant has a mental or emotional disability as defined by the FHA
An explanation of how the ESA helps alleviate at least one symptom of the disability
Valid contact information for the healthcare provider
A current date and personal signature
That’s it. If a letter contains all of these elements, it satisfies the documentation threshold. Landlords can verify the letter’s authenticity (confirm the license number, check that the professional is real) but cannot go beyond this scope. Learn more about verifying a clinician’s license to ensure your letter holds up to scrutiny.
For service dogs, the only two questions a landlord (or any covered entity) can ask are:
Is the animal required because of a disability?
What work or task has the animal been trained to perform?
These questions come from ADA guidance and carry over to housing under the FHA. If the disability is readily apparent and the animal’s task is obvious (a guide dog for a visibly blind person, for example), even these two questions are off limits. The landlord must simply accept the animal.
Assistance animals are not pets under federal law. This means standard pet policies do not apply to them. A landlord cannot enforce breed restrictions, size limits, weight caps, or species restrictions against an assistance animal the way they would against a pet. Each request must be evaluated individually based on the specific animal and the specific circumstances.
A landlord can deny an assistance animal if the specific animal poses a direct threat to the health or safety of others, or would cause substantial physical damage to the property, and those risks cannot be reduced by another reasonable accommodation. The key word is “specific.” A landlord cannot deny a Great Dane ESA because it’s a Great Dane. They could deny a specific Great Dane that has documented history of causing significant property damage or injuring people at a previous residence.
A critical carve-out that many tenants don’t know about. The FHA exempts owner-occupied buildings with four or fewer units where the owner lives in one of the units and does not use a real estate broker or agent. If your landlord falls into this category, they are not bound by FHA reasonable accommodation requirements. However, state and local fair housing laws may still apply, so the exemption is narrower than it first appears.
A separate federal law that prohibits disability discrimination in any program receiving federal financial assistance. This covers public housing, Section 8 voucher programs, and other federally funded housing. Section 504 protections for assistance animals operate independently of HUD’s enforcement guidance, meaning the May 2026 memo does not affect these protections. Colleges receiving federal funds also fall under Section 504, which is why ESAs in college housing remain protected.
Several states require that a mental health professional have an established therapeutic relationship with the patient, typically for at least 30 days, before issuing ESA documentation. States with this requirement include California, Montana, Florida, Iowa, and Arkansas. This rule exists to combat “instant” ESA letters from providers who have no real relationship with the patient. If you’re in one of these states, a letter issued after a single brief phone call will not meet the legal standard.
No government ESA database exists. No federal law requires registration, certification, or ID cards for any assistance animal. Any website claiming otherwise is misleading consumers.
Red flags for fraudulent ESA letters include missing professional license numbers, generic templates with no personalized clinical language, claims of “official certifications” or “registrations,” and letters from providers who are not licensed in the tenant’s state. Landlords have the right to examine letters for these red flags, though they still cannot demand the tenant’s diagnosis or medical history in the process. For a more detailed look at what to watch out for, this piece on spotting fake ESA letters is worth reading.
The rules differ based on the type of animal. Here’s the breakdown.
For Emotional Support Animals:
A landlord may request an ESA letter from a licensed mental health professional when the tenant’s disability or disability-related need for the animal is not readily apparent. The landlord may verify that the letter is legitimate by confirming the provider’s license number, checking that the provider exists, and ensuring the letter contains the required elements listed above.
For Service Dogs (including Psychiatric Service Dogs):
A landlord may ask the two permitted questions: Is this animal required because of a disability? What work or task has it been trained to perform? If the disability and the need are obvious, even these questions cannot be asked.
For PSDs specifically in housing:
A landlord may optionally request a clinician letter in addition to or instead of the two questions, particularly when the disability isn’t readily apparent. To understand the specific documentation requirements, this guide on PSD housing letter requirements covers what’s needed.
Across all categories, landlords may also:
Request that the tenant complete a reasonable accommodation request form (but cannot require the tenant’s provider to fill out their own special forms)
Verify the authenticity of any documentation provided
Ask general questions about how the animal alleviates symptoms (without asking for the diagnosis itself)
This is where understanding what housing evidence can landlords request and what is off limits becomes most practically important. The Fair Housing Act draws hard lines that landlords cannot cross, regardless of how suspicious they might be about a request.
Landlords CANNOT ask for or demand:
The tenant’s specific diagnosis. They can know that a disability exists. They cannot know what it is.
Medical records or treatment history. No clinical notes, no therapy summaries, no treatment plans.
Medication details. What you take, how much, or how long you’ve been on it is none of a landlord’s business.
Number of therapy sessions. The frequency of your treatment is private.
Hospitalization history. Whether you’ve ever been admitted anywhere is irrelevant to the accommodation request.
Proof of training for ESAs. ESAs are not required to be trained. Demanding training documentation for an emotional support animal is a violation.
Registration, certification, or ID cards. No federal law requires these for any assistance animal. A landlord cannot make them a condition of approval.
Direct contact with the provider without written consent. A landlord who calls your therapist without your explicit, signed permission may violate HIPAA and could face a disability discrimination claim under the FHA. Even with consent, the landlord cannot ask the provider about your medical history during that call.
Pet fees, pet deposits, or pet rent. Assistance animals are not pets. Charging pet-related fees for an ESA or service dog violates the FHA.
Breed, size, or weight restrictions. Standard pet policies do not apply to assistance animals. A blanket “no pit bulls” policy cannot be used to deny an ESA or service dog.
Notarized statements or special landlord-created forms for the provider. The landlord can accept a standard ESA letter; they cannot create their own medical questionnaire and require the provider to complete it.
Practitioners on Reddit consistently report that the most common violations they encounter are landlords demanding “registration papers,” charging pet deposits for ESAs, and asking point-blank what a tenant’s diagnosis is. Landlord forums also reveal a persistent misconception that training documentation can be required for all assistance animals, which confuses ADA public-access rules with FHA housing rules.
On May 22, 2026, HUD’s FHEO Assistant Secretary Craig Trainor signed an internal memo that permanently canceled HUD’s prior guidance on emotional support animals. The memo was effective immediately and instructed HUD staff to stop pursuing complaints from tenants whose ESAs had not been individually trained to perform disability-related tasks.
This was a significant enforcement shift. Over 20% of FHEO’s fair housing complaints had involved untrained ESAs, a caseload HUD characterized as unsustainable. The practical effect is that if a landlord denies your ESA request and you file a complaint with HUD, the agency may decline to investigate it.
This is the part many people are getting wrong, on both sides.
The Fair Housing Act has not been amended or repealed. Congress did not act.
ESAs have not been made illegal. No court has ruled that ESAs are excluded from housing protections.
Your ESA letter from a licensed mental health professional has not been invalidated.
Blanket denials of all ESA requests are still disability discrimination under the FHA.
State fair housing laws are completely unaffected.
Private lawsuits remain available. You can still sue a landlord in federal or state court for FHA violations.
As disability rights attorneys have been emphasizing since the memo dropped, housing providers who read this as broad permission to deny accommodation requests are misreading what it does. HUD reduced one enforcement mechanism. It did not change the underlying law.
For tenants: Your rights still exist, but the fastest enforcement path (filing a HUD complaint) may no longer be available for ESA-specific claims. State civil rights agencies and private attorneys become more important. Getting your documentation right, with a proper letter from a provider who has a real therapeutic relationship with you, matters more than ever.
For landlords: You have more flexibility on documentation requests, particularly in requiring evidence of a genuine therapeutic relationship. But a reflexive denial of all ESA requests will still expose you to state enforcement and private litigation. A Colorado couple was awarded $50,000 after their HOA refused to allow their emotional support animal. Those outcomes haven’t gone away.
HUD has indicated it plans to conduct formal notice-and-comment rulemaking to codify new standards, but no timeline has been announced.
One of the biggest misunderstandings after the May 2026 memo is the belief that ESA protections no longer exist. State laws tell a very different story.
California, New York, Florida, Illinois, Massachusetts, Colorado, Nevada, Oregon, New Jersey, and Washington all have independent fair housing protections that do not depend on HUD’s enforcement posture. California’s protections are particularly strong. The state’s Fair Employment and Housing Act (FEHA) independently requires housing providers to accommodate disabled tenants with assistance animals, and its protections are not conditioned on whether the animal is trained. FEHA is enforced by California’s Civil Rights Department, a state agency that operates entirely independently of HUD.
Unlike federal law, which lacks criminal penalties for ESA fraud, 17 states enforce ESA fraud laws and 34 states have service animal misrepresentation statutes. This cuts both ways: tenants with fake documentation face real legal consequences, and landlords who violate state accommodation laws face state-level enforcement that HUD’s memo cannot touch.
For state-by-state details on how these protections work, this guide to ESA laws by state covers what documentation is required in each jurisdiction.
Understanding what housing evidence can landlords request and what is off limits also means understanding the situations where a denial is legally defensible. There are a limited number of legitimate grounds.
1. Direct threat to health or safety. The specific animal (not the breed, not the species) poses a documented threat to other residents, and that threat cannot be mitigated through another reasonable accommodation.
2. Substantial physical damage to the property. Again, this must be based on evidence about the specific animal, not generalizations.
3. Undue financial or administrative burden. The accommodation would impose costs or operational changes that are genuinely unreasonable given the housing provider’s resources and the nature of the property. This is a high bar and is rarely met for a single assistance animal.
4. Fraudulent or incomplete documentation. If the ESA letter is clearly fake (no license number, no provider contact information, generated by a website with no clinical evaluation), a landlord can deny the request and ask for proper documentation. One case in Pensacola involved a property manager who faced HUD charges after evicting a tenant who had provided legitimate ESA documentation three times.
5. The property falls under the Mrs. Murphy exemption. Owner-occupied buildings with four or fewer units where no broker is involved are exempt from the FHA.
6. The accommodation would fundamentally alter the nature of the housing operation. This is the rarest ground and almost never applies to a single assistance animal.
If you’ve been denied and believe the denial was unlawful, this resource on whether landlords can legally deny ESAs walks through your options.
ESA | Service Dog | Psychiatric Service Dog | |
|---|---|---|---|
Can landlord request documentation? | Yes, ESA letter from licensed provider (when disability not apparent) | Only the two permitted questions (when disability/task not apparent) | Two permitted questions, plus optional clinician letter |
Can landlord request training proof? | No | No (but can ask what task the dog performs) | No (but can ask what task the dog performs) |
Can landlord require registration? | No | No | No |
Can landlord charge pet fees? | No | No | No |
Can landlord apply breed/size restrictions? | No | No | No |
Protected under FHA? | Yes | Yes | Yes |
Protected under ADA (public access)? | No | Yes | Yes |
No. Under the Fair Housing Act, emotional support animals are assistance animals, not pets. Landlords cannot charge pet deposits, pet rent, or any additional fees for them. They can hold a tenant financially responsible for actual damage the animal causes, but they cannot impose fees as a condition of approval.
No. No government ESA database or registry exists in the United States. No federal law requires registration, certification, or an ID card for an emotional support animal. Any website claiming your animal must be in a database to receive housing protection is misleading you. A valid ESA letter from a licensed mental health professional is the only documentation that matters.
No. A landlord can ask whether you have a disability that requires an accommodation and how the animal helps. They cannot ask what your diagnosis is, what medications you take, how severe your symptoms are, or any other details about your medical history or treatment.
The Fair Housing Act still protects you, even though HUD has scaled back its enforcement. File a complaint with your state’s civil rights or fair housing agency. Many states, including California, New York, and Florida, have independent enforcement mechanisms. You can also pursue a private lawsuit in federal or state court. Blanket ESA denials remain a form of disability discrimination.
It depends on your state. California, Montana, Florida, Iowa, and Arkansas currently require that your mental health provider have an established therapeutic relationship with you (typically at least 30 days) before issuing ESA documentation. If you live in one of these states, a letter from a provider you’ve never spoken with before will not meet the legal standard.
Not without your written and signed consent. Contacting your provider without permission may violate HIPAA and could constitute disability discrimination under the FHA. Even if you do provide consent, the landlord cannot use that call to fish for information about your diagnosis, treatment history, or medical records.
No. There is no legitimate ESA certification process under federal law. No government agency certifies emotional support animals. If your landlord is demanding a certification, they are either misinformed or making an unlawful demand. What they can request is a valid ESA letter from a licensed mental health professional.
No. The Mrs. Murphy exemption covers owner-occupied buildings with four or fewer units where the owner does not use a real estate broker. Private owners who own no more than three single-family homes and don’t use brokers or discriminatory advertising are also exempt. However, state and local fair housing laws may still apply even when the FHA does not, so check your state’s rules.
