Undue burden in housing

Undue burden under the Fair Housing Act

The Fair Housing Act makes it unlawful to refuse reasonable accommodations in rules, policies, practices or services when they may be necessary for a person with a disability to have an equal opportunity to use and enjoy a home. An accommodation that creates an undue financial and administrative burden, or that fundamentally alters the provider's operations, is not considered reasonable.

The HUD and DOJ joint statement on reasonable accommodations lists factors to weigh case by case:

• The cost of the requested accommodation
• The financial resources of the provider
• The benefit the accommodation would provide to the person
• Whether a less costly alternative would meet the person's needs

Fundamental alteration

A request may also be denied if it would be a fundamental alteration, which the joint statement describes as a change that alters the essential nature of a provider's operations. For example, a landlord generally isn't required to start offering services it doesn't provide to anyone.

Letting a tenant keep a trained dog despite a no-pets rule is usually just a policy exception. HUD's own regulation gives the example of a no-pets building that must allow a guide dog.

Undue burden and assistance animals

Permitting an assistance animal typically involves little direct cost to the provider. Concerns about the specific animal's behavior are handled under the separate direct-threat standard instead.

If a provider believes a request is too burdensome, the joint statement encourages an interactive discussion to find an alternative that meets your needs. The burden analysis is individual; it can't be a blanket policy.

Accommodation request tips

Clear communication often prevents disputes and makes it easier for a provider to see that allowing your dog is a simple policy exception rather than a burden.

• Put your request in writing and keep copies
• Explain the accommodation you need in plain terms
• Offer reliable documentation if your disability or need isn't obvious
• Respond promptly to reasonable questions
• Ask for any denial and its reasons in writing

Employment and public access rules

Employers use a related but distinct standard, "undue hardship," under Title I of the ADA. Businesses open to the public apply their own ADA rules for service animals.

In September 2025, HUD withdrew its 2020 assistance animal notice (FHEO-2020-01) and its 2013 notice, saying they should not be relied on as authoritative. The Fair Housing Act and HUD's reasonable accommodation regulation were not withdrawn. A PSD letter documents your disability-related need; it doesn't decide whether a request is reasonable.
