What Counts as a Disability Under the Fair Housing Act?

Under the Fair Housing Act, you count as having a disability if you fit any one of three categories: you have a physical or mental impairment that substantially limits at least one major life activity, you have a documented record of such an impairment, or a housing provider treats you as having one. Meeting any single category triggers the full set of protections, including the right to request reasonable accommodations and modifications.¹

Physical and Mental Impairments That Qualify

Federal regulations define a physical impairment as any physiological disorder, condition, cosmetic disfigurement, or anatomical loss affecting a body system. That covers the neurological, musculoskeletal, cardiovascular, respiratory, reproductive, digestive, and endocrine systems, among others. Mental impairments include intellectual disabilities, organic brain syndrome, emotional illness, and specific learning disabilities.¹

The regulation names specific conditions as examples, but treats the list as non-exhaustive. Named conditions include cerebral palsy, autism, epilepsy, muscular dystrophy, multiple sclerosis, cancer, heart disease, diabetes, and HIV infection. Alcoholism and drug addiction also qualify as impairments, with one important limit: the addiction cannot be caused by current illegal drug use. A person in recovery from heroin addiction is covered; a person actively using heroin is not.¹

Substantial Limitation of a Major Life Activity

Having a diagnosis is just the starting point. The impairment has to substantially limit at least one major life activity. Major life activities include walking, seeing, hearing, breathing, eating, sleeping, standing, lifting, speaking, learning, reading, concentrating, thinking, communicating, interacting with others, and working.

“Substantially limits” means a significant restriction compared to most people. The analysis looks at what you actually cannot do or struggle to do, not at what your diagnosis is called. Severe rheumatoid arthritis that leaves you unable to grip a doorknob is a substantial limitation on manual tasks. Mild seasonal allergies are not a substantial limitation on breathing, even though both conditions technically involve a body system named in the regulations.

Short-lived, minor conditions generally fall outside protection. A sprained ankle that heals in a few weeks would not qualify. But duration alone isn’t the test. An impairment lasting less than six months can still be substantially limiting if its effects are severe enough. A serious spinal injury that keeps you off your feet for four months can qualify even though recovery is expected.

A Record of an Impairment

The second category covers you if you have a documented history of a qualifying impairment, even if you’re currently healthy. Someone in long-term cancer remission keeps their protections. A landlord cannot refuse to rent because they worry a past condition might return.²

This prong also protects people who were wrongly classified. If a school record labeled you as having an intellectual disability when you didn’t, or a medical file reflects a since-retracted psychiatric diagnosis, those documents cannot be used against you in a housing decision.

Being Regarded as Having a Disability

The third category flips the lens. It protects you when a housing provider treats you as though you have a qualifying impairment, whether or not you actually do. If a property manager refuses to rent because they assume a facial scar means you have a contagious illness, that decision violates the law even if you are perfectly healthy.²

Most stereotyping-based discrimination lands here. A landlord who sees a prospective tenant using a cane and assumes the person “can’t take care of the apartment” is acting on perception, not fact. The law holds housing providers accountable for those assumptions whether the perceived impairment exists or not.

What the Law Excludes

Two exclusions are written directly into the statute. First, current illegal drug use is excluded. Someone currently using or addicted to a controlled substance illegally is not protected, though someone in recovery or in a treatment program is.³ The FHA itself does not define “current,” so courts have looked to the ADA and Rehabilitation Act for guidance on where that line falls.

Second, the statute provides that an individual is not considered to have a handicap solely because that individual is a transvestite.³

There is also a separate exception for direct threats. Even if you meet the definition of disability, a housing provider can deny or terminate housing if you pose a direct threat to the health or safety of others or would cause substantial property damage. That determination has to rest on an individualized assessment based on reliable, objective evidence such as recent conduct or a documented history of specific harmful acts, and it must account for whether treatment or medication has since eliminated the threat. Fear, speculation, and stereotypes about a particular disability are explicitly prohibited as bases for exclusion.²

What Qualifying Gets You

Meeting the definition unlocks two practical rights: reasonable accommodations and reasonable modifications. They are different things, and the distinction usually decides who pays.

A reasonable accommodation is a change to a rule, policy, or practice. Waiving a no-pets policy for an assistance animal, assigning a closer parking space, or letting a tenant receive packages at the front office because stairs are inaccessible are all accommodations. Housing providers generally bear the cost, unless the request would impose an undue financial or administrative burden or fundamentally alter their operations.⁴

A reasonable modification is a structural change to the property itself, like grab bars, widened doorways, or a ramp. In private housing, the tenant typically pays. In federally assisted housing, the provider generally pays, because structural accessibility falls under Section 504 of the Rehabilitation Act. For multifamily buildings constructed for first occupancy after March 13, 1991, the provider may also be responsible if the requested change should have already been built in under federal design and construction requirements.⁴

You do not need special language to make either request. It can be oral, written, or communicated any other way, and it does not need to include the phrase “reasonable accommodation” or reference the Fair Housing Act. A family member, healthcare professional, or other representative can make the request for you. Putting it in writing creates a record if the provider later denies a request was made.

Assistance Animals

Assistance animals are one of the most common accommodation requests. Under HUD guidance, an assistance animal is any animal that works, provides assistance, or performs tasks for a person with a disability, or that provides emotional support alleviating one or more effects of a disability. The Fair Housing Act does not separate service animals from emotional support animals the way the ADA does for public accommodations. Both fall under a single housing umbrella.⁵

Because an assistance animal is not a pet, providers cannot charge pet deposits, pet fees, or pet rent, and cannot apply breed or weight restrictions. A provider can deny the request only if the specific animal poses a direct threat, would cause significant property damage, or if granting it would fundamentally alter operations.⁵

HUD has said that online ESA letters sold by websites issuing certificates for a fee are not sufficient to establish a disability or a disability-related need. Documentation from a legitimate licensed healthcare professional who delivers services remotely can be reliable; a purchased certificate from a site with no real clinical relationship is not.⁶

What a Landlord Can Ask

Housing providers walk a narrow line on verification. If your disability or your need for the accommodation is obvious or already known, the provider cannot ask for additional information. A wheelchair user requesting a ground-floor unit does not need to produce medical paperwork.⁷

When a disability is not apparent, the provider can request reliable disability-related information, but only enough to confirm three things: that you meet the FHA’s definition of disability, what accommodation you need, and the connection between the two. Acceptable verification can come from a doctor, therapist, peer support group, social service agency, or your own credible statement combined with proof that you receive Social Security disability benefits. Detailed medical records and specific diagnostic information are usually neither necessary nor appropriate to request.⁷

Any disability-related information the provider receives must be kept confidential. It can be shared only with people who need it to evaluate the request or when disclosure is required by law.

If You’ve Been Denied

If a housing provider has discriminated against you based on disability, you can file a complaint with HUD or file a private lawsuit in federal court. HUD complaints must generally be filed within one year of the discriminatory act. A federal lawsuit must typically be filed within two years. Many states have their own fair housing agencies with different deadlines.

Filing with HUD is free and does not require an attorney. HUD investigates and can refer the case to an administrative law judge with authority to impose civil penalties.⁸ A private lawsuit can produce compensatory damages for emotional distress and out-of-pocket losses, and courts can award punitive damages and attorney fees.
