Emotional support animal housing law in Montana

The federal position, as of 2026

On 22 May 2026 HUD permanently rescinded its 2020 assistance animal notice and narrowed its own enforcement to animals individually trained to do work or perform tasks for a person with a disability. That is the Americans with Disabilities Act service animal test, and an emotional support animal does not meet it. A complaint to HUD about a refused emotional support animal is now unlikely to produce a finding of reasonable cause.

What survived:

• The Fair Housing Act itself is unchanged. Congress wrote the statute and HUD only changed how it enforces it, so the statutory duty to make reasonable accommodations for people with disabilities still stands.
• The private right of action is unchanged. A tenant can still sue in state or federal court, and a court interpreting the statute is not bound by an agency's enforcement posture.
• State law is untouched. HUD has no authority over a state statute, and this is where the protection now mostly lives.

Montana law

Montana has its own fair housing statute, the Montana Human Rights Act (Mont. Code Ann. § 49-2-305), enforced by the Montana Human Rights Bureau. A state complaint runs on state law, so HUD changing its own enforcement priorities does not decide it.

Montana also legislated on emotional support animals directly, which most states have not. These are the sections that matter:

• Mont. Code Ann. § 70-24-114: Enacted by HB 703 in 2023 and amended by SB 149 in 2025, this section sets out what a landlord may require for an assistance animal, what a provider must do before issuing documentation, and graduated penalties for fraudulent documentation.

The 30-day rule in Montana

HB 703 took effect on 1 October 2023 and was tightened again by SB 149 in 2025. The provider must have been treating the person for at least thirty days before issuing the letter, and the document has to carry the licence type, number and effective date.

This is the single most important thing to know before paying anyone for a Montana letter, and it is the thing online letter services are least likely to tell you. A document that does not meet Mont. Code Ann. § 70-24-114, enacted by HB 703 (2023) is not documentation a housing provider has to treat as reliable, so the money buys nothing.

What a housing provider may ask for

• Where the disability is not obvious, reliable documentation of the disability and of the disability-related need for the animal.
• Nothing about the nature or severity of the condition, no diagnosis, and no medical records.
• No certification, licence, training or registration for the animal, because none of those exist for an emotional support animal.
• No breed, weight or size restriction applied as though the animal were a pet, where the accommodation is granted.

Grounds a provider can still rely on

• The specific animal poses a direct threat to the health or safety of others that cannot be reduced by another reasonable accommodation. This has to be about the actual animal and its actual conduct, not about a breed.
• The animal would cause substantial physical damage to property.
• The accommodation would impose an undue financial and administrative burden, or fundamentally alter the provider's operations.
• The documentation is not reliable.

Misrepresentation in Montana

Montana has no misrepresentation penalty on the books that we have been able to verify. Supplying false information to a housing provider is still a bad idea on ordinary contract and fraud grounds, and it can support an eviction.

If you move

A letter is tied to the licence of the clinician who wrote it, not to your lease. Moving out of Montana does not void it, but a new housing provider is entitled to reliable documentation, and a clinician licensed only in Montana is a weaker answer to that question once you live somewhere else. Montana sits in the Mountain, and the rules next door are not the same.

Arizona, Colorado, Idaho, Nevada, New Mexico, Utah run on the federal position plus their own fair housing statute, much as Montana does.

Where a complaint goes

To the Montana Human Rights Bureau, under the Montana Human Rights Act (Mont. Code Ann. § 49-2-305). A state complaint is decided on state law, which is why it matters more now than it did before May 2026.

A Montana housing provider handed a letter has no register to check it against, which is the reason so much of this market is worthless paper. Every letter issued here carries a six digit ESA ID and a public verification page, so a landlord can confirm the letter is real, current, and issued by a licensed clinician without being shown a single word about anybody's health.
