Charging pet rent and a pet deposit is legal in most states, but the laws governing them differ by state and by the type of charge. A refundable pet deposit almost always counts toward your state’s overall security deposit cap. A non-refundable pet fee is allowed in most states but prohibited in those that require every upfront tenant payment to be refundable. Monthly pet rent is treated as rent, not a deposit, so it faces far fewer restrictions. One firm federal rule overrides all of this: landlords cannot charge any pet deposit, fee, or rent for an assistance animal.
The Three Pet Charges Are Not the Same Thing
Landlords typically collect money for pets in one of three ways, and the legal treatment of each is different enough that confusing them creates real problems.
- A pet deposit is a one-time refundable payment held to cover pet-related damage like scratched floors or stained carpet. If the pet causes no damage beyond normal wear and tear, the full amount comes back at lease end. These typically run $200 to $500.
- A pet fee is a one-time non-refundable charge meant to offset the general wear of having an animal in the unit. The landlord keeps it regardless of the condition at move-out. These usually range from $150 to $300.
- Pet rent is a recurring monthly charge added to base rent. The national average sits around $35 per month. You never get pet rent back.
The split between refundable and non-refundable is the one that controls the legal analysis. A pet deposit follows your state’s security deposit rules, which usually means the landlord owes you an itemized accounting of deductions and must return the unused balance within a set timeframe. A pet fee and pet rent carry no such obligation.
How States Regulate Pet Deposits
Most states don’t have a standalone pet deposit statute. Instead, they fold the pet deposit into the general security deposit, which is subject to a statutory cap. The majority of states set that cap between one and three months’ rent, and any pet deposit has to fit inside that total. If a landlord already collects the maximum allowed as a standard security deposit, there’s no legal room left for a separate pet deposit on top of it.
A handful of states do set a specific pet deposit limit on its own, ranging from as low as one-quarter of a month’s rent to a full month’s rent. In states with no explicit cap, courts generally expect pet deposits to be reasonable in relation to the actual risk the pet poses, and an outsized charge can be challenged.
Refund rules for pet deposits mirror whatever your state requires for security deposits. The landlord has to return unused funds within the state’s deadline, provide an itemized list of deductions, and can only withhold money for actual damage beyond normal wear and tear. The fact that a pet lived in the unit is not, by itself, a reason to keep the deposit.
Non-Refundable Pet Fees Are Banned in Some States
Non-refundable pet fees are legal in most states, but a meaningful number prohibit them. Those states treat any upfront payment from a tenant, other than rent itself, as a security deposit that has to be refundable. Calling the charge a “pet fee” in the lease does not change its legal character. If the money was collected to cover potential property costs and the tenant owes nothing at move-out, the landlord has to return it.
Before paying a non-refundable pet fee, check whether your state allows them. If you’re in a state that requires all deposits to be refundable, a landlord who pockets your pet fee may owe you the money back along with penalties. This is one of the more common landlord-tenant disputes, and it’s usually the tenant who doesn’t realize they had a right to a refund.
Why Pet Rent Faces Fewer Limits
Pet rent is treated as rent, not as a deposit. That one classification changes everything. Security deposit caps don’t apply. Refund requirements don’t apply. As long as the tenant agrees to the amount in a signed lease, a landlord can charge monthly pet rent without running into the statutory limits that restrict deposits.
This is why pet rent has grown more popular with landlords over the past decade. It produces a steady income stream outside deposit regulations, and the landlord doesn’t have to hold the money in escrow or return it at lease end. The tradeoff for tenants is straightforward: you pay more every month with no prospect of recovering any of it.
Some local jurisdictions have begun capping pet rent, so this area is evolving. As of now, broad state-level restrictions on pet rent are rare.
No Pet Charges Are Allowed for Assistance Animals
The Fair Housing Act prohibits landlords from charging pet deposits, pet fees, or pet rent for assistance animals. This covers both trained service animals and emotional support animals, because under federal law these animals are not pets. They serve a function for individuals with disabilities, and landlords are required to make reasonable accommodations in their rules and policies so tenants with disabilities have equal opportunity to use and enjoy their housing.1Office of the Law Revision Counsel. United States Code Title 42 – 3604 Discrimination in the Sale or Rental of Housing
In practice, a landlord with a no-pets policy must still allow a tenant’s assistance animal. The landlord cannot require a separate deposit, charge extra monthly rent, or impose a one-time fee for the animal. HUD’s guidance is explicit that housing providers may not charge any fee or deposit for assistance animals.2U.S. Department of Housing and Urban Development (HUD).

What a landlord can do is hold the tenant responsible for actual damage the animal causes. Repair costs come out of the tenant’s standard security deposit, the same way damage from any other source would. The landlord just cannot require a separate, dedicated animal deposit or impose extra financial burdens tied to the animal.3U.S. Department of Housing and Urban Development (HUD). Assistance Animals
If the disability is not obvious, a landlord may ask for documentation from a licensed healthcare professional who has personal knowledge of the tenant. The documentation needs to confirm that the tenant has a disability affecting a major life activity and that the animal serves a therapeutic purpose related to it. Landlords cannot demand detailed medical records or require a specific diagnosis. HUD has also said that online certificates or registrations sold to anyone who pays a fee are not reliable documentation, but the existence of one is not grounds to deny the accommodation if the tenant can supply proper paperwork from a real provider.2U.S. Department of Housing and Urban Development (HUD).

If a landlord charges you a pet-related fee for an assistance animal or denies a reasonable accommodation request, you can file a housing discrimination complaint with HUD’s Office of Fair Housing and Equal Opportunity. There’s no cost to file.3U.S. Department of Housing and Urban Development (HUD). Assistance Animals
What to Check in the Pet Addendum Before You Sign
Any pet-related charge should be spelled out in a written pet addendum attached to the lease. Verbal agreements about pets create disputes that are expensive and difficult to resolve. A solid pet addendum covers:
- Approved animals, including species, breed, weight limit, and the number of pets allowed.
- Financial terms, meaning the exact pet deposit amount, whether it’s refundable, any monthly pet rent, and how deductions will be calculated at move-out.
- Behavioral expectations, including noise limits, leash rules for common areas, and waste cleanup responsibilities.
- Consequences for violations, like repeated disturbances or bringing in an unauthorized animal.
If a landlord later tries to charge pet rent that the lease never mentions, the tenant has leverage to dispute it. A tenant who signs a detailed addendum and then violates it has far less room to argue. Both sides benefit from putting it in writing.
When Pet Damage Exceeds the Deposit
A pet deposit does not always cover the full cost of damage. A large dog can destroy flooring, doors, and drywall in ways that run well past a $500 deposit. When that happens, the landlord’s first step is to document everything with dated photos, repair estimates, and receipts.
The landlord then sends the tenant a written demand for the balance owed beyond the deposit. If the tenant doesn’t pay, the landlord can pursue the debt in small claims court for smaller amounts or through a standard civil lawsuit for larger sums. These cases turn on documentation. A landlord with before-and-after photos, professional estimates, and a clear accounting of how the deposit was applied usually recovers the balance. One without those records usually doesn’t.
Tenants facing a damage claim that feels inflated should request the itemized deduction statement their state requires and compare the claimed costs against reasonable market rates. Normal wear from a pet’s presence, like minor scuffing near a door, cannot be deducted from the deposit. Actual damage, like carpet shredded down to the padding, can.
