Pet Deposit Laws in Missouri: Limits, Refunds, and Your Rights as a Renter
November 1, 2026
Pet deposit laws in Missouri are less settled than most renters expect. The state caps security deposits at two months’ rent, but the statute’s treatment of pet money is technical, and published guides do not agree on whether a pet deposit counts toward that cap.
This article walks through what Missouri law says, where sources split, and what you can do about it. You will see how deposits, fees, and pet rent differ, what a landlord can deduct, how fast you should get your money back, and when you can push back.
If you want the bigger picture on animal ownership first, start with our overview of pet laws in Missouri. Then come back here for the rental-specific rules.
Important Note: This article is general information, not legal advice. Statutes and local ordinances change, so check the current text of Mo. Rev. Stat. § 535.300 or talk with a Missouri attorney or tenant-rights organization before relying on it in a dispute.
What Is a Pet Deposit in Missouri?
A pet deposit is money a landlord collects before you move in with an animal, meant to cover pet-related damage when you leave. Unlike a fee, a true deposit belongs to you unless the landlord has a documented reason to keep part of it.
The wording in your lease matters more than the label on the invoice. Missouri landlords use “pet deposit,” “pet fee,” “pet cleaning charge,” and “pet rent” loosely, and each one can carry different legal consequences. Read the clause carefully before you sign.
Does Missouri Allow Landlords to Charge a Pet Deposit?
Yes. Missouri has no statute forcing a private landlord to accept pets, so a landlord can refuse animals outright or set conditions. According to our guide to pet-friendly housing laws, landlords can charge a pet deposit or a pet fee if tenants have pets, which also means they can simply refuse pets altogether.
The deposit needs to be written into your lease. TurboTenant notes that state law doesn’t limit the amount landlords can require as long as the lease agreement outlines it.
Maximum Pet Deposit in Missouri
Missouri sets no dollar limit written specifically for pet deposits. There is no limit on how much a landlord can collect for a pet deposit in Missouri, according to that same animalofthings.com guide, though the answer gets more complicated once you factor in the general security deposit cap.
Some sources say the two-month cap still applies to your total deposits. Others say the pet deposit sits outside it. The next section explains the disagreement.
Does a Pet Deposit Count Toward Missouri’s Security Deposit Limit?
This is the question where published sources split. The statute at Mo. Rev. Stat. § 535.300 limits a landlord to two months’ rent, and one summary of it says the cap counts every refundable deposit collected up front regardless of the label (“pet deposit,” “cleaning deposit”).
Other sources read subsection 8 differently. Tenant Screening Background Check states that Section 535.300.8 carves a pet deposit out of the two-month security-deposit limit, so it sits on top of that cap. A Kansas City property manager reaches the same conclusion, saying Missouri excludes pet deposits entirely from its two month deposit cap under RSMo 535.300.
| Reading of the Statute | What It Means for You | Sources Taking This View |
|---|---|---|
| Pet deposit is inside the cap | Security deposit plus pet deposit cannot exceed two months’ rent | RentoHQ, Pet Deposits by State, Lease Lenses |
| Pet deposit is outside the cap | Pet deposit can be added on top of up to two months’ rent | TurboTenant, Tenant Screening Background Check, Alpine Kansas City |
Important Note: Because sources conflict, treat the two-month figure as a possible ceiling on your combined deposits, not a guarantee either way. Ask your landlord in writing how they classify each charge, and keep a copy of the lease clause.
As a practical matter, a total of two months’ rent or less is the safest position for a landlord. If your combined up-front deposits run higher, ask for an itemized breakdown and consider a consult with a tenant-rights group.
Pet Deposit vs. Pet Fee vs. Pet Rent in Missouri
These three charges look similar on a rental application, but they work very differently. A deposit is refundable, a fee is a one-time charge, and pet rent is a recurring monthly cost.
| Charge | How It Works | Returned at Move-Out? |
|---|---|---|
| Pet deposit | One-time payment held against pet damage | Yes, minus documented deductions |
| Pet fee | One-time payment, often for cleaning or admin costs | Usually no, if the lease says so |
| Pet rent | Monthly charge added to rent | No, it is a payment for use of the unit |
Missouri does not cap pet rent. A Kansas City analysis explains that pet rent is a recurring charge treated as ordinary rent, with no statutory cap in Missouri or Kansas.
When you compare listings, add up the total first-year cost of all three. A low deposit paired with high monthly pet rent can cost more over twelve months than a larger refundable deposit.
Are Pet Deposits Refundable in Missouri?
A true deposit should be refundable. If your lease calls the money a “deposit,” Missouri’s deposit-return process in § 535.300 generally applies, so you should expect either your money back or an itemized list of deductions within 30 days.
One older Q&A on JustAnswer takes a different view, saying a pet deposit is generally treated as non-refundable unless the lease says otherwise. That page is many years old, so weigh it accordingly and rely on your written lease.
The safest approach is to get the refund terms in writing. A clause that says “refundable pet deposit” removes most of the ambiguity.
Are Non-Refundable Pet Fees Legal in Missouri?
Sources disagree here as well. Pet Deposits by State says non-refundable pet fees are not permitted and that all deposits must be refundable. Steadily takes the opposite approach, noting that for non-exempt pets, landlords may opt for a refundable deposit or a non-refundable pet fee.
The likely dividing line is labeling. Calling a charge a “deposit” brings the refund rules into play, while a clearly labeled one-time fee in the lease is more defensible as a non-refundable charge. A landlord who calls it a fee but treats it like a deposit when withholding it invites a dispute.
Pro Tip: Before paying, ask this question: “If I move out with no pet damage, will this money come back to me?” Get the answer in writing, in the lease or in an email.
Can Landlords Charge a Pet Deposit for Service Animals and ESAs in Missouri?
No. Under federal fair housing rules, service animals and emotional support animals are not pets, so landlords cannot charge a deposit, fee, or pet rent for them. Under federal law (ADA and FHA), landlords in Missouri cannot charge pet deposits, pet fees, or pet rent for service animals, according to Pet Deposits by State.
Breed and weight limits do not apply either. A landlord may ask only whether the animal is required because of a disability and what task it has been trained to perform, and cannot demand certification or registration for a service animal.
You can still be charged for actual damage the animal causes, the same as any tenant. For more detail, see our pages on service dog laws in Missouri and emotional support animal laws in Missouri.
How Much Is a Typical Pet Deposit in Missouri?
With no state cap, amounts vary by property and city. Many landlords charge $200-$500 pet deposits plus $25-$50 monthly pet rent per animal, though the guide stresses that exact amounts vary widely by property type and location.
Smaller landlords in rural areas may charge less or nothing. Larger complexes in St. Louis and Kansas City often charge more and combine a deposit with pet rent.
Treat those numbers as a rough range, not a rule. Compare at least two or three listings near you before assuming a quote is standard.
Can a Landlord Charge a Pet Deposit and Pet Rent Together in Missouri?
Yes. A Kansas City rental analysis from August 2026 says nothing in Missouri or Kansas law prohibits combining pet rent with a refundable pet deposit on the same tenancy.
The combination is common. The deposit covers damage at move-out, while pet rent is the ongoing price of having an animal in the unit.
Both charges should appear in your lease. If a landlord adds pet rent later without your written agreement, that is a lease change, which the last sections below cover.
Pet Deposits for Multiple Pets, Fish and Caged Pets in Missouri
Missouri law does not set rules by number or type of pet. Landlords decide this in their own pet policies, so you will see “per pet” deposits, a flat deposit for the household, or a limit on the number of animals.
Fish tanks and small caged animals get treated differently from property to property. Some landlords waive the charge for a single aquarium or hamster, while others apply the full deposit. Others ban certain species altogether, and that is allowed for ordinary pets.
Ask for the pet policy in writing and list every animal you plan to keep. An unlisted pet can become a lease violation even if you paid a deposit for a different one.
What Can a Landlord Deduct From a Pet Deposit in Missouri?
A landlord can deduct for actual damage beyond ordinary wear and tear. During this period, landlords can deduct unpaid rent, late fees, and damages beyond normal wear and tear from the deposit, according to Steadily.
Typical pet-related deductions include:
- Scratched doors, floors, or window frames
- Carpet stains or odor that professional cleaning cannot fix
- Chewed trim, baseboards, or fixtures
- Yard damage such as holes or heavy lawn burn, if the lease covers it
Routine carpet wear from foot traffic is not a pet deduction, and neither is repainting a unit that needed it anyway. Take dated photos at move-in and move-out so you can show the unit’s condition.
How Long Does a Landlord Have to Return a Pet Deposit in Missouri?
Thirty days. Within thirty days after the date of termination of the tenancy, the landlord shall return the full amount of the security deposit or furnish a written itemized list of the damages along with the balance, as quoted on Recording Law’s summary of the statute.
If a landlord treats your pet deposit as part of the security deposit, expect the same clock. If the landlord treats it as separate, the lease should still state when it comes back. A landlord who wrongfully withholds may owe penalties: up to twice the amount wrongfully withheld, plus court costs and reasonable attorney’s fees.
- Give your landlord a written forwarding address when you move out.
- Count 30 days from the date the tenancy ends.
- If nothing arrives, send a written demand letter.
- If that fails, consider small claims court, which handles disputes up to $5,000 according to Deposit Hawk.
Can a Landlord Keep Your Pet Deposit Without Proof of Damage in Missouri?
Not if the deposit is refundable. A landlord who keeps money must back it up with a written itemized list of damages, and a tenant has the right to attend the move-out inspection, according to Rentable.
Photos, repair estimates, and receipts are what make a deduction hold up. Even the older JustAnswer page notes that landlords should document pet-caused damage with photos, repair estimates, or inspection reports.
A flat “pet cleaning” charge with no receipt is the weakest kind of deduction. If you believe a withholding is improper, you can dispute it in writing and, if needed, file in small claims.
Pro Tip: Photograph or video every room at move-in and again at move-out, with dates visible. A clean photo record is often what decides a deposit dispute.
Can a Landlord Raise the Pet Deposit or Change the Pet Policy Mid-Lease in Missouri?
Generally no, not on a fixed-term lease. Your lease is a contract, and a landlord cannot unilaterally add charges or change terms without your agreement. If your lease says you may keep a pet for a stated deposit, that deal holds until the lease ends.
Month-to-month tenants are in a weaker position. Month-to-month termination notice is one month by either party, so a landlord can give notice of a changed policy or end the tenancy, though changes should still follow your lease’s notice terms.
At renewal, expect the landlord to propose new numbers. That is the moment to compare your deposit and pet rent against what similar properties charge.
Can You Negotiate a Pet Deposit in Missouri?
Often, yes. Missouri sets no cap on pet charges, so the amounts reflect the landlord’s choices, and independent landlords have more room to bargain than large management companies.
Several approaches tend to work:
- Offer a pet reference letter from a prior landlord or a vet record showing vaccinations
- Provide a pet resume with photos, training history, and temperament details
- Ask to trade a lower deposit for slightly higher pet rent, or the reverse
- Offer a professional carpet cleaning at move-out
Get any agreed change in writing and attached to your lease. For the wider set of rules that affect your animals, from leash laws in Missouri to dog bite liability, those pages cover the points a landlord’s pet policy often references.
Key Takeaways for Missouri Renters
Missouri allows pet deposits, pet fees, and pet rent, and it sets no pet-specific dollar cap. The unsettled point is whether a pet deposit counts toward the two-month security deposit limit, so get each charge itemized and labeled in your lease.
Keep your documentation, return dates, and written forwarding address ready at move-out. The 30-day return rule and the double-damages remedy give you real leverage if a landlord keeps your money without proof.
