ADA & Reasonable Accommodation Rules in Montana 2026
Service animals, emotional-support animals, and reasonable accommodation duties under the federal Fair Housing Act and Mont. Code § 49-2-305.
Every Montana landlord operates under two layers of disability-housing law at once: the federal Fair Housing Act (42 U.S.C. 3604(f)) and the Montana Human Rights Act (MCA Title 49, Chapter 2). On disability, Montana does not go beyond the federal floor so much as it restates it. The operative language sits in MCA 49-2-305(5), and it tracks the FHA almost word for word: you must grant reasonable accommodations to your rules and policies, and you must permit reasonable modifications to the physical unit. The two are not the same thing, and the difference decides who pays.
A request does not have to say "reasonable accommodation" or come with a doctor's letter to trigger your duty. Once a tenant asks for a change tied to a disability, Montana and federal law expect you to engage, weigh it, and either grant it or state a lawful reason you cannot. This page lays out how that plays out under Montana law specifically.
What Montana Law Adds
Adds marital status, age, creed.
Accommodation vs. modification: who pays
The distinction is the single most important thing to get right. A reasonable accommodation is a change to a rule, policy, practice, or service. A reasonable modification is a physical change to the unit or common area.
Under MCA 49-2-305(5)(a)(ii), you cannot refuse a reasonable accommodation "in rules, policies, practices, or services" when it may be necessary to give a person with a disability equal opportunity to use and enjoy the home. Waiving a no-pets rule for an assistance animal, assigning a reserved parking space near the door, or accepting rent on a different day to align with a benefits check are all accommodations. These cost you nothing but administrative effort, and you absorb that cost.
A reasonable modification under MCA 49-2-305(5)(a)(i) is different. Installing a grab bar, widening a doorway, adding a ramp, or lowering a countertop is made at the expense of the person with a disability. The tenant pays. Your obligation is to permit the work, not to fund it. This is the mirror image of the federal FHA rule for privately owned housing, and it is where landlords most often overcorrect by refusing outright rather than simply allowing the tenant-funded change.
Restoration and conditions you may impose
Permitting a modification does not mean surrendering the unit's condition permanently. MCA 49-2-305(5)(a)(i) lets a landlord, "when it is reasonable to do so," condition permission on the renter's agreement to restore the interior to the condition that existed before the modification, excluding reasonable wear and tear.
Two limits matter here. First, restoration applies to interior changes; you generally cannot demand removal of a modification that a future tenant could reasonably use, and you cannot use restoration as a pretext to deny. Second, under FHA guidance that Montana follows, where restoration is likely to be expensive you may require the tenant to fund an escrow or interest-bearing account for the restoration cost, but you cannot demand a lump-sum security deposit increase as the price of saying yes. Document the modification scope and the restoration agreement in writing before work begins.
Assistance and service animals
The most common accommodation request Montana landlords see is for an assistance or service animal against a no-pets policy. Under the FHA framework that governs MCA 49-2-305(5) accommodations, an assistance animal is not a pet. You may not charge a pet deposit, pet rent, or pet fee for it, and "no pets" is not a lawful basis to deny.
You may verify. If the disability or the disability-related need for the animal is not obvious, you may ask for reliable documentation of the disability and the need, but not the person's diagnosis or medical records. You keep the right to hold the tenant responsible for actual damage the animal causes, and you may deny a specific animal that poses a direct, documented threat or would cause substantial physical damage that cannot be reduced by another accommodation. A breed or a general fear is not enough.
The interactive process and lawful denials
Montana law does not spell out a scripted procedure, but the enforcement standard is an interactive, good-faith exchange. When a request is ambiguous or the disability-related need is unclear, you engage, ask for what you legitimately need, propose alternatives, and respond within a reasonable time. Silence or delay is treated as a denial.
You may lawfully deny a request that is not "reasonable." Under the Montana Human Rights Act, an accommodation that imposes an undue hardship or that would endanger the health or safety of any person is not a reasonable accommodation. Federal law adds that you need not grant a request that imposes an undue financial and administrative burden or works a fundamental alteration of your operations. A denial should rest on the specific facts of the request, not a blanket policy, and you should offer to discuss an alternative that would meet the tenant's need. Blanket refusals and unexplained no's are what generate liability.
Coverage, exemptions, and enforcement
Most Montana rental housing is covered. The narrow exemptions in MCA 49-2-305 are the familiar FHA carve-outs: MCA 49-2-305(11) limits application to an owner-occupied building of no more than two families where the owner lives in one unit, and MCA 49-2-305(10) preserves qualified housing for persons 55 and older against familial-status claims. Note that even where an owner-occupied exemption reduces some duties, disability accommodation obligations under the FHA still reach most transactions involving an agent or public advertising.
Newer construction carries an affirmative design duty: multifamily buildings with four or more units first occupied after March 13, 1991 must meet FHA design-and-construction accessibility standards, accessible routes, usable doors, and usable kitchens and bathrooms, which Montana parallels at MCA 49-2-305(5)(a)(iii). A tenant who believes you violated these rules can file with the Montana Human Rights Bureau (DLI, Employment Relations Division) within 180 days, or with HUD within one year. The Bureau can be reached at 1-800-542-0807 or Human Rights Bureau, P.O. Box 1728, Helena, MT 59624.
No Misrepresentation Statute in Montana
Montana has not enacted a statute criminalizing misrepresentation of a pet as a service or assistance animal. A Montana landlord who suspects fraud should still process the request properly, denial without engaging in the interactive process and without requesting reliable documentation creates FHA liability that far exceeds any plausible harm from a fraudulent ESA claim.
The Cost of Mishandling a Reasonable-Accommodation Request
The most common mistake in Montana reasonable-accommodation cases is responding with a flat denial, "no pets means no pets", instead of engaging in the interactive process. The interactive process is itself a substantive duty. A landlord who refuses to consider the request, demands more than HUD permits, or imposes a pet fee on an assistance animal will lose at HUD even if the underlying accommodation could have been reasonably denied.
Reasonable Modification, Often Confused With Accommodation
Reasonable modification (42 U.S.C. § 3604(f)(3)(A)) is a structural change, a grab bar, a ramp, lowered cabinets. The tenant pays. The landlord must permit the modification and may require restoration to original condition at move-out (except for changes that would not significantly affect re-rental). Reasonable accommodation is a change to a rule or policy. The landlord pays no out-of-pocket cost; the cost is administrative. Montana follows the federal rule.

Frequently Asked Questions
Does Montana require me to pay for a tenant's grab bars or ramp?
No. Under MCA 49-2-305(5)(a)(i), reasonable physical modifications to a rental unit are made at the expense of the person with a disability. Your duty is to permit the work, not to fund it. This differs from a reasonable accommodation to a rule or policy, which you must grant at your own administrative cost.
Can I make the tenant undo the modification when they move out?
Sometimes. MCA 49-2-305(5)(a)(i) lets you condition permission, when reasonable, on the tenant's written agreement to restore the interior to its prior condition, less reasonable wear and tear. You generally cannot force removal of a change a future tenant could reasonably use, and you cannot use restoration as an excuse to deny the request.
Can I charge a pet deposit for a service or assistance animal?
No. An assistance or service animal is treated as a reasonable accommodation, not a pet. You may not charge a pet deposit, pet fee, or pet rent for it. You may still hold the tenant liable for any actual damage the animal causes, and you may deny a specific animal that poses a direct, documented threat.
When can I lawfully deny an accommodation request in Montana?
You may deny a request that is not reasonable. Under the Montana Human Rights Act, an accommodation that imposes an undue hardship or endangers anyone's health or safety is not reasonable. Federal law adds undue financial and administrative burden and fundamental alteration as grounds. Base any denial on the specific request, not a blanket policy, and offer to discuss an alternative.
What documentation can I ask for?
If the disability and the disability-related need for the accommodation are both obvious, you cannot ask for anything. If either is not apparent, you may request reliable documentation that the person has a disability and needs the requested change. You may not demand a diagnosis, medical records, or the specific nature of the disability.
Does the ADA apply to my rental units?
The ADA generally does not reach the interior of private dwelling units; those are governed by the Fair Housing Act and MCA 49-2-305. ADA Title III can apply to public-facing areas such as a rental office or leasing center, which function as places of public accommodation. For most landlord accommodation and modification duties, the FHA and Montana Human Rights Act control.
How long does a tenant have to file a discrimination complaint?
A complaint with the Montana Human Rights Bureau must be filed within 180 days of the alleged discriminatory act. A federal complaint with HUD may be filed within one year. Because the state window is shorter, tenants are often advised to act quickly; landlords should keep dated records of every accommodation request and response.
