Service animals, emotional-support animals, and reasonable accommodation duties under the federal Fair Housing Act and Mo. Rev. Stat. § 213.040.
Every Missouri landlord operates under two overlapping fair-housing regimes: the federal Fair Housing Act and the Missouri Human Rights Act (MHRA). Both require you to bend your rules, and sometimes your building, so a tenant with a disability can use and enjoy the home on equal footing. Missouri's housing-discrimination statute, RSMo 213.040, mirrors the federal duty almost word for word: you cannot refuse a reasonable accommodation in your rules, policies, practices, or services, and you cannot refuse to permit a reasonable structural modification. Missouri adds no dollar caps and no broader payer rule of its own, but it does route enforcement through the Missouri Commission on Human Rights (MCHR), which gives tenants a state complaint path with its own clock. Knowing where the two duties differ, and where they are identical, is what keeps a routine request from turning into a discrimination claim.
Mirrors federal FHA; adds ancestry.
The law treats a change to how you run the property differently from a change to the property itself. A reasonable accommodation is an exception to a rule, policy, practice, or service, waiving a no-pets policy for an assistance animal, assigning a reserved parking space near a unit, allowing a live-in aide, or accepting a guarantor for a tenant whose disability affects income. Under RSMo 213.040, refusing an accommodation that "may be necessary to afford such person equal opportunity to use and enjoy a dwelling" is an unlawful housing practice.
A reasonable modification is a physical change to the unit or common areas, a grab bar, a ramp, a widened doorway, or lowered cabinets. RSMo 213.040 makes it unlawful to refuse to permit modifications "necessary to afford such person full enjoyment of the premises." The critical distinction is cost, covered next. Both duties apply to nearly all Missouri rental housing; the narrow owner-occupied and single-family exemptions in the federal Act and the MHRA are the same ones you already know from other fair-housing questions.
This is where accommodations and modifications part ways. A reasonable accommodation is the landlord's cost to absorb, waiving a fee or changing a policy costs you the exception, not out-of-pocket construction. A reasonable modification, by contrast, is paid for by the tenant. RSMo 213.040 spells this out: the duty is to permit, "at the expense of the person with the disability," reasonable modifications of the premises. You are required to allow the work, not to fund it.
Missouri also preserves the landlord's protection on the back end. Where reasonable, you may condition permission for a modification on the tenant agreeing to restore the interior to the condition that existed before the modification, reasonable wear and tear excepted. That covers interior changes a future tenant wouldn't want; you generally cannot demand removal of features like a ramp or wider doorway that don't interfere with the next occupant's use. One important carve-out: in publicly funded housing subject to Section 504 of the Rehabilitation Act, the housing provider, not the tenant, ordinarily bears the cost of structural modifications. Private, unsubsidized Missouri landlords fall under the tenant-pays rule.
Neither the Fair Housing Act nor RSMo 213.040 prescribes a form, a fixed response deadline, or magic words. A tenant simply has to let you know, in any manner, that they need a change because of a disability. That triggers your duty to engage. Treat it as a good-faith back-and-forth: acknowledge the request promptly, and don't let silence or delay become a constructive denial, which HUD and the MCHR both treat as a violation.
You may ask for verification only when the disability or the disability-related need is not obvious. If a tenant's need for a service is apparent, demanding a doctor's letter is itself a red flag. When the disability isn't visible, you may request reliable documentation that (1) the person meets the statutory definition of disability, a physical or mental impairment that substantially limits a major life activity, a record of one, or being regarded as having one, and (2) there is a connection between the impairment and the requested change. You may not demand medical records, a diagnosis, or details about the condition's severity. If the exact accommodation requested is a burden, offer an effective alternative, the law requires a workable solution, not the tenant's first choice.
The duty is not unlimited. A Missouri landlord may deny a request when:
Document your reasoning contemporaneously and offer alternatives before refusing outright. A denial that skips the interactive process, or leans on a blanket policy ("we never allow pets," "no exceptions to parking rules") instead of an individualized analysis, is the fact pattern that most often produces a finding against the landlord.
A Missouri tenant who believes a request was mishandled has two parallel routes, and the deadlines differ, so calendar both. A complaint to the Missouri Commission on Human Rights (MCHR) under the MHRA must be filed within 180 days of the alleged discriminatory act. A complaint to HUD under the federal Fair Housing Act has a longer window, one year from the violation. Tenants may also file suit in court. Because the MCHR and HUD have a work-sharing arrangement, a single filing can trigger investigation under both laws.
The MCHR intake line is 573-751-3325 (toll-free complaint hotline 1-877-781-4236), and complaints can be emailed to MCHRIntake@labor.mo.gov. For landlords, the practical takeaway is that the 180-day state clock runs quickly: a request you deny or ignore in the spring can surface as a formal complaint before the lease term is out. Keeping written records of each request, your verification steps, and your reasoning is the single best protection if a complaint lands.
This statute is generally enforced in public-accommodation contexts (restaurants, retail) rather than as part of a landlord-tenant dispute. For housing, the practical landlord defense against a fraudulent ESA claim is to require reliable documentation from a healthcare professional with a therapeutic relationship to the tenant, not to attempt criminal enforcement.
The most common mistake in Missouri 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 (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. Missouri follows the federal rule.

This page summarizes Missouri fair-housing duties under RSMo 213.040 and RSMo 213.010, the federal Fair Housing Act (42 U.S.C. 3604(f)), and Section 504 of the Rehabilitation Act, cross-checked against Missouri Commission on Human Rights guidance. It is general information for rental-housing owners and managers, not legal advice. Fair-housing determinations turn on the specific facts of each request, and enforcement standards evolve through HUD and MCHR rulings. Before denying an accommodation or modification request, or if a complaint has been filed, consult a Missouri attorney or the MCHR directly.
Not materially. RSMo 213.040 tracks the federal Fair Housing Act closely, using nearly identical language for both reasonable accommodations in rules, policies, practices, or services and reasonable modifications of the premises. Missouri adds no dollar caps, no fixed response deadline, and no broader payer rule. The main state-specific feature is the enforcement path through the Missouri Commission on Human Rights, with its own 180-day filing deadline.
In private, unsubsidized housing, the tenant pays. RSMo 213.040 requires the landlord to permit reasonable modifications "at the expense of the person with the disability." You must allow the work but are not required to fund it, and you may reasonably require the tenant to restore the interior to its prior condition (normal wear and tear excepted) when they leave. The exception is publicly funded housing subject to Section 504, where the provider generally pays.
No. When the disability and the disability-related need are obvious, requesting documentation is itself a fair-housing violation. You may ask for reliable verification only when the disability or the need is not apparent, and even then you may confirm only that the person meets the definition of disability and that the request is connected to it. You cannot demand a diagnosis, medical records, or details about the condition.
Yes. Waiving a no-pets policy for a service animal or support animal is a classic reasonable accommodation under both the Fair Housing Act and RSMo 213.040. You may not charge pet fees or deposits for it, and you may request disability-related verification only when the need is not obvious. A denial generally must rest on an individualized finding of direct threat or substantial property damage, not a blanket no-pets rule.
You may deny when there is no connection between the request and a disability, when the request would impose an undue financial and administrative burden, when it would fundamentally alter your operations, or when it poses a direct threat to others' health or safety that no alternative can reduce. Each ground requires an individualized, documented assessment. Denying based on a blanket policy or a stereotype about a disability is the most common source of liability.
A complaint to the Missouri Commission on Human Rights under the Missouri Human Rights Act must be filed within 180 days of the alleged discrimination. A federal complaint to HUD under the Fair Housing Act has a one-year window. Tenants may also sue in court. Because of the state-federal work-sharing arrangement, one filing can be investigated under both laws.
