Pet Rent Laws in Montana: What Landlords Can Charge and What You Can Push Back On
November 10, 2026
Pet rent laws in Montana are looser than most renters expect. State law does not set a cap on monthly pet rent, and it does not even mention pet rent by name. What Montana does regulate closely is how any pet-related charge is labeled, held, and returned.
That gap matters for your wallet. A landlord can charge a monthly fee for your dog, but they cannot dodge the deposit rules by calling the money something else. This article walks through each question renters ask, from what is legal to how to negotiate, so you can read your lease with confidence.
Is Pet Rent Legal in Montana?
Yes. Montana landlords can charge monthly pet rent for ordinary pets. According to iPropertyManagement’s Montana lease guide (Rev. 2026), state law does not regulate pet rent, though federal law bars fees for service animals and emotional support animals.
Montana also lets landlords refuse pets entirely. A strict “no pets” clause is enforceable, and Montana’s landlord-tenant relationship is governed by MCA 70-24, which gives owners wide latitude over which animals they allow, according to our guide to pets in Montana apartments.
Key Insight: “Legal” does not mean “unregulated.” Pet rent is allowed, but deposits and fees that cover cleaning or damage fall under Montana’s security deposit statutes.
Pet Rent vs. Pet Fee vs. Pet Deposit in Montana
These three charges look similar on a lease but work very differently. A pet deposit is refundable money held against damage. A pet fee is a one-time charge, and pet rent is a recurring monthly payment.
The label matters less than the purpose. Under MCA 70-25-101, RPM Explore notes that a fee for cleaning and damages is presumed to be a security deposit no matter how it is designated. So a “non-refundable pet fee” meant to cover pet damage is legally a deposit and must be handled under the same refund rules.
| Charge | How It Works | Montana Treatment |
|---|---|---|
| Pet deposit | One-time, held against damage | Treated as part of the security deposit; refundable |
| Pet fee | One-time charge at move-in | If it covers cleaning or damage, it is presumed a deposit |
| Pet rent | Recurring monthly charge | Allowed; no state cap or specific rule |
Does Montana Cap Pet Rent?
No. Montana sets no statutory limit on pet rent, pet deposits, or security deposits. PetDepositsByState classifies the state as landlord-friendly for tenants with pets, and says landlords may charge any amount, though deposits must come back within 30 days (10 days if there are no deductions).
Some online tenant sites claim a cap of one month’s rent plus a pet deposit. That figure conflicts with other sources and with RPM Explore’s reading that MCA leaves deposit amounts up to the lease. Treat the lease as the controlling document.
Important Note: Sources disagree on whether Montana has any deposit cap. Most legal summaries say there is none, so do not assume a limit will protect you. Ask for any charge in writing before you sign.
How Much Is Pet Rent in Montana?
Montana has no official average because the state does not track it, and my research found no reliable, dated Montana-specific pricing survey. Pet rent is set building by building, so what you pay depends on the landlord, the city, and the pet.
Your best approach is to compare. Ask each property for its full pet cost sheet, including deposit, one-time fee, and monthly rent, and add them up over a 12-month lease. A building with low monthly rent but a large upfront fee can cost more than one with a higher monthly charge.
- Request the pet policy in writing before applying.
- List the deposit, any one-time fee, and monthly rent separately.
- Multiply monthly pet rent by your lease length.
- Add the one-time costs and compare total first-year cost across buildings.
Is Pet Rent Charged Per Pet in Montana?
Montana law does not say, so it is up to each landlord. Some charge a flat monthly amount for all pets, while others charge per animal. Landlords can also set limits on quantity, which Steadily’s Montana pet guide lists alongside breed and size restrictions.
If you have two cats, ask directly whether the rent doubles. Get the answer written into the lease, because verbal quotes are hard to enforce later.
Which Pets Can Landlords Charge Pet Rent For in Montana?
Landlords can set rules for any animal that is not a service animal or documented ESA. According to MontPIRG’s renter FAQ as cited by Animal of Things, landlords may limit any animal that is not a service animal, and the Montana Code only lists dogs and miniature horses as protected service animal species.
In practice, that means dogs, cats, birds, reptiles, and small mammals can all be subject to pet rent or an outright ban. Breed and weight limits are also allowed. PetDepositsByState notes that many landlords set weight limits commonly between 25 and 75 pounds, and these are set by landlords rather than state law.
If you own a breed that often draws restrictions, see our rundown of American Bully laws in Montana before you apply.
Can a Landlord Add Pet Rent Mid-Lease in Montana?
Generally, no, not during a fixed-term lease. Rent and fees are terms of the contract, so a landlord cannot add a new charge unless the lease allows it or you agree to the change. I found no Montana statute that specifically addresses mid-lease pet rent, so this is based on general contract principles.
Month-to-month tenants are more exposed. A landlord can typically change terms by giving proper written notice before the next rental period. Read your lease for any clause that lets the landlord update pet policies, and never agree to a new charge without getting it in writing.
Pet Rent in Rent-Controlled and Local Rules in Montana
Montana does not have rent control. The state has a long-standing ban on local rent control, so no city can cap what a landlord charges, pet rent included. I did not find any Montana city ordinance that regulates pet rent specifically.
Local rules still affect pet owners in other ways. Cities such as Billings, Missoula, Bozeman, and Great Falls have their own animal ordinances on licensing and nuisance, and those can come into play for your household. Check our guides on leash laws in Montana and pet vaccination laws in Montana so your pet stays compliant, since a violation can become a lease issue.
Can Landlords Charge Pet Rent for ESAs and Service Animals in Montana?
No. Service animals and emotional support animals are treated as accommodations, not pets. Peak Property Management in Bozeman states that landlords cannot charge a pet deposit, a pet fee, or any pet rent for these animals, even if the property does not allow pets.
Under RPM Explore’s summary, Montana House Bill 703, effective October 1, 2023, sets the process for evaluating ESA requests. If your need is not obvious, a landlord can ask for information from a health care practitioner who has treated you for at least 30 days, but cannot ask for a specific diagnosis or medical records.
You are still responsible for damage. A landlord may deny a request only when the animal poses a direct threat that cannot be reduced through another reasonable accommodation, and you remain liable for any damage the animal causes.
Important Note: RPM Explore reports that in May 2026, HUD rescinded its 2020 assistance animal guidance and narrowed its enforcement focus toward animals trained to perform a specific task. This may affect how federal complaints about untrained ESAs are prioritized, so keep your documentation thorough and consider contacting Disability Rights Montana if you hit resistance.
Can Landlords Charge Pet Rent for Visiting or Pet-Sitting Pets in Montana?
Montana law does not address visiting animals, so any charge depends on your lease. If your lease says no pets without written approval, a pet you are sitting for a week could technically violate it. A landlord is unlikely to charge ongoing pet rent for a short visit, but could treat a long stay as an unauthorized pet.
Protect yourself by asking first. A short email asking permission for a specific pet and date range gives you a written record and removes any argument later.
What If You Have an Unauthorized Pet in Montana?
Do not hide it. Under Montana law, a landlord can evict you for an unauthorized pet. According to the Griz Renter blog, the landlord must give written notice allowing three days to remove the pet or move out, and can begin eviction if you do not comply.
The three-day period is confirmed by iPropertyManagement, which lists three days for unauthorized pets or residents, compared with 14 days for issues the law does not specifically cover.
If you already have a pet your landlord does not know about, ask to add it to the lease now. Offering to pay the deposit or monthly rent costs far less than a notice to quit.
Is Pet Rent Refundable in Montana?
Pet rent is not refundable. It is a recurring payment for the right to keep a pet, much like regular rent, so you do not get it back at move-out. The refundable part is the pet deposit.
Because a pet deposit is legally part of the security deposit, the same timeline applies. Per RPM Explore, MCA 70-25-202 requires the full deposit back within 10 days if there is no damage, no cleaning needed, no unpaid rent, and you can show utilities are paid. Deductions must reflect actual damage or cleaning cost, not a flat charge.
Landlords must also give a written move-in condition statement under MCA 70-25-206. If they skip it, they lose the right to withhold deposit money for damage unless they can prove by clear and convincing evidence that you caused it.
Pro Tip: Photograph the unit on move-in day, including floors, doors, and carpet, and keep the written condition statement. This is your best defense against pet-damage deductions.
Can You Negotiate Pet Rent in Montana?
Yes, and with no state cap, there is real room to bargain. Landlords set these charges, so they can also lower or waive them.
- Offer a pet résumé with vet records, vaccination proof, and a reference from a previous landlord.
- Propose a larger refundable deposit in exchange for lower monthly rent.
- Offer to sign a longer lease.
- Show proof of renter’s insurance with pet liability coverage.
- Ask whether the fee drops after a year of good history.
Staying current on Montana pet vaccination requirements helps your case, since landlords worry most about liability. For households on a budget, lower-maintenance animals sometimes draw smaller fees and fewer restrictions.
Is Pet Rent Taxable Income for Landlords in Montana?
Yes. Pet rent is rental income, and landlords generally report it as income on their federal tax return, like any other rent. I did not find a Montana-specific rule treating pet rent differently, so it follows ordinary rental income treatment.
Refundable deposits are handled differently, since they are not income until the landlord keeps them for damage or unpaid rent. Landlords with questions about reporting should talk to a tax professional. This section is general information, not tax advice.
What a Montana Lease Must Say About Pet Rent
Montana law does not require a specific pet rent clause. Still, your lease is the only thing that makes a charge enforceable, so it should spell everything out. Steadily’s guide stresses that landlords should clearly outline pet policies in lease agreements to avoid misunderstandings.
Before signing, check that the lease states:
- The exact monthly pet rent amount and due date
- Whether the amount is per pet or per household
- The deposit amount and that it is refundable under MCA 70-25
- Any one-time fee and what it covers
- Approved animal type, breed, and weight
- The process for adding or removing a pet
