Can You Have Pets in Apartments in Missouri? What the Law Really Says

If you’re apartment hunting in St. Louis, Kansas City, or anywhere in between, you’ve probably noticed that “no pets” clauses show up in a lot of Missouri leases. That’s not an accident. Missouri gives landlords wide latitude to decide who gets to keep a dog, cat, or lizard on the premises, and understanding where that authority starts and stops can save you from a costly lease violation or a denied application.

This guide walks through what Missouri law actually allows landlords to do about pets, what pet deposits and fees can legally look like, and where federal protections for service animals and emotional support animals override a property’s standard policy.

Can a Landlord Ban Pets in Missouri

Yes. Missouri landlords have significant discretion when it comes to animals in rental housing. Missouri landlords do not have specific legal requirements to allow pets unless it’s related to disability accommodations, though they often set their own pet policies that tenants must agree to. That means a “no pets” clause in your lease is fully enforceable, and a landlord can legally reject your application simply because you have a dog.

This authority extends beyond a blanket yes-or-no decision. Missouri landlords have broad authority to prohibit pets, restrict certain breeds or species, and charge additional deposits or monthly pet rent. A property might allow cats but not dogs, or allow small caged animals while banning anything with fur entirely. According to Steadily’s overview of Missouri rental pet laws, landlords typically define these terms in the pet policy section of the lease itself, so the specific language you sign matters more than any general assumption about what’s “normal.”

Species restrictions matter just as much as breed restrictions. A landlord who tolerates a goldfish tank might draw the line at a ball python or a tarantula, even where the animal itself is perfectly legal to own in Missouri. If you’re considering an unconventional pet, it helps to first confirm the animal is allowed under state and local exotic animal ownership rules before you even bring up housing. Our guide to exotic pets legal in Missouri breaks down which species you can legally keep statewide, which is a separate question from whether your specific building will permit them.

Pro Tip: Get any verbal “yes” on pets in writing before you sign. A property manager’s spoken approval carries no legal weight once the written lease says otherwise.

Pet Deposits and Pet Fees: What Missouri Allows

Missouri law doesn’t cap what a landlord can charge for a pet. Landlords in Missouri can charge a pet deposit or a pet fee if tenants have pets, and unlike security deposits, there is no state-imposed limit on the amount, though the deposit should be reasonable to avoid legal challenges. A Springfield television station’s fact-check confirmed the same thing directly: there’s no law against pet fees in Missouri, and charging a pet deposit or pet fee is legal, according to KY3’s Fact Finders investigation.

In practice, that flexibility shows up as a mix of one-time and recurring charges. Landlords commonly structure pet costs as a refundable deposit plus ongoing monthly pet rent, and many Missouri landlords charge $200-$500 pet deposits plus $25-$50 monthly pet rent per animal. Here’s how the major fee categories typically compare:

Fee Type	Typical Missouri Range	State Cap	Notes
Security deposit	Up to 2 months’ rent	Capped by state statute	Must be held in a bank or credit union account
Pet deposit	$200-$500	No cap	Refundable if no pet damage occurs
Monthly pet rent	$25-$50 per animal	No cap	Non-refundable, ongoing charge
Service animal or ESA fee	$0	Prohibited	Cannot be charged under the Fair Housing Act

The general security deposit itself, separate from any pet-specific charge, is capped by state law. Landlords in Missouri can charge tenants up to 2 months’ rent for security deposits, and they may charge a separate pet deposit in addition to the standard security deposit, with state law placing no limit on that additional amount as long as the lease outlines it.

Important Note: Sources differ slightly on whether a pet deposit counts toward the two-month security deposit cap. State law technically defines a “security deposit” in a way that excludes pet-specific deposits, meaning the two are usually treated as separate charges. If your combined deposits feel excessive relative to your rent, it’s worth asking your landlord to itemize each charge in writing.

If you’re trying to avoid these fees altogether, size and species can work in your favor. Smaller, quieter animals are less likely to trigger a full pet deposit at some properties, which is one reason renters often gravitate toward options like the rabbit breeds kept as pets that fit easily in a studio or one-bedroom unit.

Breed and Weight Restrictions in Missouri

Breed-specific rules are legal for ordinary pets, even though many renters find them frustrating. Landlords routinely exclude breeds associated with liability concerns. Some landlords ban certain dog breeds that many people believe have a propensity toward violence, such as pit bulls and Rottweilers, and while whether certain breeds are truly dangerous is a topic of controversy, landlords are legally entitled to ban these breeds because fair housing laws apply to human beings, not to dogs. That’s according to Anthem’s landlord guidance on pet-friendly rental policies.

Weight limits work the same way and are often used instead of, or alongside, breed lists. Instead of, or in addition to, banning certain breeds, some landlords limit the weight of dogs, for example only allowing dogs under 20 pounds. A large, gentle mixed-breed dog can get shut out of a unit for exceeding a weight cap even if the individual animal has never shown aggressive behavior.

These restrictions have one major exception, and it’s an important one. Breed and weight rules simply don’t apply to service animals or emotional support animals. Missouri landlords must accept a valid ESA letter, even in a no-pet building, and cannot charge pet deposits, pet rent, or apply breed, size, or weight restrictions. A pit bull that would be denied as an ordinary pet cannot be denied on breed grounds if it’s a documented service animal or ESA.

Species-based restrictions can be just as strict as breed rules, particularly for exotic pets. Reptile and invertebrate owners sometimes run into blanket bans regardless of how docile the individual animal is. If your household includes something like a pet chameleon or a pet scorpion, it’s worth checking your lease’s pet clause closely, since our guides on chameleon species kept as pets and scorpion species kept as pets cover animals that many standard “no dogs or cats” policies don’t actually address one way or the other.

Service Animals and Emotional Support Animals: Your Rights in Missouri

Assistance animals sit in a completely different legal category than pets, and Missouri landlords must treat them that way. Missouri and federal law prohibit discrimination in rental housing against those who use service animals, your landlord can’t charge you extra for having one, you must be allowed full and equal access to all housing facilities, and a “no pets” provision in your lease doesn’t apply to your service animal. That summary comes from Nolo’s legal encyclopedia on Missouri service dog and ESA law.

Emotional support animals get similar treatment under a combination of federal and state law. Emotional support animal owners in Missouri are protected under both the federal Fair Housing Act and the Missouri Human Rights Act, and together these laws require most landlords to accept a valid ESA letter and waive pet fees, even in buildings with no-pet policies. Landlords can still ask for documentation confirming the disability-related need, but they can’t demand a specific diagnosis or medical records.

The protection isn’t unlimited, though. The Fair Housing Act only allows landlords to deny animals that are a safety threat to other residents, cause property damage, or would fundamentally change the nature of the housing provider’s business, such as keeping a pig in an apartment with minimal access to outdoor space. A documented history of aggression or property destruction can still justify a denial, but a landlord can’t reject a request based on assumptions about a breed or species alone.

Important Note: Claiming a pet is an emotional support animal without a legitimate disability-related need isn’t just an ethical gray area. Misrepresenting an ESA in Missouri carries real legal consequences, so only pursue this accommodation if you genuinely qualify under a licensed provider’s evaluation.

Can a Landlord Change the Pet Policy Mid-Lease in Missouri

Once you’ve signed a lease, the terms inside it are locked in for both sides, and pet policy is no exception. Missouri requires all pet-related terms to be clearly stated in written lease agreements, verbal pet agreements aren’t legally enforceable, and landlords cannot unilaterally change pet policies mid-lease without tenant consent. If your original lease said pets were welcome, a landlord generally can’t reverse that decision on you before renewal, and the reverse is also true.

This principle holds up under broader landlord-tenant law as well, not just Missouri-specific pet guidance. Generally, a landlord cannot unilaterally change the lease terms mid-lease, even if it is to change from not allowing pets to allowing pets, according to legal analysis published by Super Lawyers. Mid-lease changes typically require a signed amendment both parties agree to, not a memo taped to your door.

What happens if you bring home a pet despite a no-pet clause? You’re the one exposed here, not the landlord. If your lease prohibits pets but you acquire one anyway, your landlord can pursue eviction proceedings, though they must follow proper notice procedures, typically providing 30 days’ written notice to cure the violation before filing for eviction. That notice period is your window to either remove the animal, negotiate an addendum, or find alternate housing before things escalate further.

What to Do If Your Landlord Won’t Allow Your Pet in Missouri

Start by rereading your lease carefully. A denial based on breed, weight, or species is legal for an ordinary pet, but if you have a service animal or documented ESA, a landlord’s refusal may violate the Fair Housing Act. In that case, a denial has to hold up to real scrutiny. A landlord can deny an emotional support animal if it poses a direct threat to others’ safety or causes significant damage, but evidence of past behavior or factual proof is required, and rejection cannot be based on assumptions or stereotypes about certain breeds.

If you believe your rights were violated, you have a few concrete next steps:

1. Request the denial in writing. A written explanation creates a paper trail and often prompts a landlord to reconsider a decision that wouldn’t survive scrutiny.
2. Consult a landlord-tenant attorney. Many offer a low-cost initial consultation specifically to assess whether an assistance animal denial is defensible.
3. File a HUD complaint if needed. If involving an attorney isn’t successful, the tenant can file a complaint with HUD, and there are two HUD offices covering different parts of Missouri. Complaints can be submitted online, according to Scott Law Firm’s guidance on assistance animal disputes.
   
   

If your pet doesn’t qualify for FHA protection and the landlord’s “no pets” stance is firm, your realistic options are negotiating an addendum, offering a larger deposit, or looking at properties with more flexible pet policies. It’s also worth considering species that many “no pets” buildings quietly permit, since policies are usually written with dogs and cats in mind. Renters in this position often turn to low-maintenance pets or, for households with children, low-maintenance pets for kids that fit inside a tank or terrarium rather than requiring separate lease approval.

Small, contained animals are frequently the easiest path forward when a building’s pet policy is strict. Options like pet insect species, pet crab species, and pet snail species live entirely inside an enclosure, produce no noise complaints, and rarely show up on a landlord’s radar as “pets” requiring a deposit at all. It’s still worth confirming with your lease language directly, but these are practical alternatives if a dog or cat isn’t in the cards at your current address.

Pro Tip: Before signing anywhere, ask specifically whether the property’s pet policy differs for renewal terms versus your first lease. Some Missouri landlords tighten pet rules at renewal even when the initial lease was permissive.

Missouri’s rental market gives landlords significant control over pet policy, but that control has real boundaries once assistance animals, written lease terms, and fair housing protections come into play. Reading your lease closely before you sign, documenting any accommodation requests in writing, and knowing when to escalate to HUD are the practical steps that protect you either way.
