The Fair Housing Act
The law
The statute did not change in 2026. How one agency enforces it did, and the difference between those two things is the whole story.
Where the duty comes from
The Fair Housing Act, 42 U.S.C. 3601 and following, prohibits discrimination in housing on several grounds including disability. The provision that matters here makes it unlawful to refuse to make reasonable accommodations in rules, policies, practices or services when such accommodations may be necessary to afford a person with a disability equal opportunity to use and enjoy a dwelling.
Read that carefully, because almost every argument in this area is contained in it. Rules and policies are what gets excepted, which is why a no-pets policy is the paradigm case. Necessary is a real threshold. And equal opportunity to use and enjoy a dwelling is what the accommodation has to be aimed at, which is why an emotional support animal letter is a housing document and does nothing in a shop.
The definition of disability
A physical or mental impairment that substantially limits one or more major life activities, a record of such an impairment, or being regarded as having one. Current illegal use of a controlled substance is expressly excluded. The statute contains no list of qualifying conditions, deliberately.
What the statute does not say
- It does not mention emotional support animals, or animals at all. Everything in this area is the general accommodation duty applied to animals by guidance and case law.
- It does not define a species restriction, which is why no species is excluded in principle and why reasonableness does the work instead.
- It does not require training, certification or registration, and no register exists.
- It does not set an expiry date for documentation, which is why twelve months is convention rather than law.
What changed in May 2026
Nothing in the statute. HUD rescinded its own 2020 guidance notice and adopted an enforcement standard under which its Office of Fair Housing and Equal Opportunity finds reasonable cause only where an animal is individually trained to perform work or tasks. That is a decision about how one agency spends its enforcement resources. Congress wrote the statute, and a court construing it is not bound by an agency enforcement posture.
Who is covered
Most housing, with narrow exemptions for owner-occupied buildings of four units or fewer and for single-family houses rented by an owner who owns no more than three without an agent. The advertising provision applies regardless of exemption, and most states have their own statute reaching further.
Common questions
- Did the Fair Housing Act change in 2026?
- No. HUD changed how it enforces the animal provisions. The statute, the duty and the private right of action are untouched.
- Does the Act mention emotional support animals?
- No. It creates a general reasonable accommodation duty, and assistance animals are an application of it.
