Pet and Animal Policies in Rental Properties: A Landlord's Complete Guide

Most landlords have a pet policy. Far fewer have one that actually holds up.

The gap is usually not about pets — it is about emotional support animals and service animals, which are governed by federal fair housing law, not your preferences. A "no pets" clause does not cover them, and treating them like pets can expose you to a fair housing complaint.

This guide covers how to structure a pet policy that works for pets, handles ESA and service animal requests correctly, and protects you when either side of the conversation gets difficult.

Pets, emotional support animals, and service animals: the legal difference

These three categories are not interchangeable. Each has different legal treatment.

Pets are animals kept for companionship with no disability-related function. You have full discretion over whether to allow them, what restrictions to set, and what fees to charge.

Emotional support animals (ESAs) are animals that provide emotional or psychological benefit to a person with a documented disability. They are not trained to perform specific tasks. They are protected under the Fair Housing Act — landlords must provide reasonable accommodation unless doing so causes an undue hardship or fundamentally alters the nature of the housing. You cannot charge a pet deposit or pet rent for an ESA.

Service animals are individually trained to perform specific tasks for a person with a disability (for example, a guide dog or a seizure alert dog). They are protected under both the Fair Housing Act and the Americans with Disabilities Act. No pet fees, no breed restrictions, no deposit — period.

The practical implication: a lease that says "no pets, no exceptions" will not protect you if a tenant submits a documented ESA or service animal request. You need a policy that handles each category separately.

What your pet policy needs to cover

If you allow pets, your policy should address:

Species and breeds allowed (for example, cats and dogs only; no exotic animals)
Size or weight restrictions (for example, dogs under 50 lbs)
Maximum number of pets per unit
Pet deposit amount (note: many states cap total deposits including pet deposits)
Pet rent (a monthly surcharge in lieu of or in addition to a deposit)
Tenant liability for pet-caused damage beyond the deposit
Rules for common areas — leash requirements, waste cleanup, prohibited areas
What happens if an unauthorized pet is discovered

The most enforceable approach is a separate pet addendum attached to the lease, signed by the tenant at move-in and re-signed at each renewal.

What your ESA policy needs to cover

For ESA requests, your policy should establish a clear process:

How to submit a request: written request with supporting documentation from a licensed healthcare provider
What documentation is acceptable: a letter from a licensed mental health professional, physician, or other licensed provider stating that the tenant has a disability-related need for the animal
Response timeline: HUD guidance suggests responding within 10 days of receiving a complete request
What you can and cannot ask: you can verify that the person has a disability and that the animal is connected to that disability. You cannot ask for a specific diagnosis, require the animal to be certified or registered, or deny the request solely because you do not allow pets.

Note: if your property has four or fewer units and you personally live in one of them, the FHA's small-landlord exemption may apply. Consult a local attorney for guidance on how this applies to your specific situation.

Even if you approve an ESA, the tenant remains liable for any damage the animal causes beyond normal wear and tear. Document the unit's condition at move-in and at move-out, and note any animal-related damage separately.

Some states have enacted laws specifically addressing ESA documentation fraud — requiring documentation from providers with an established clinical relationship. Check your state's current rules.

What about service animal requests?

Service animal requests under the FHA require very little verification. You may ask only two questions:

Is this animal required because of a disability?
What work or task has the animal been trained to perform?

You may not ask about the nature of the disability, require documentation, or require the animal to demonstrate its task. The same damage liability rules apply — the tenant is responsible for animal-caused damage.

Structuring your pet addendum

A pet addendum should be a separate document, attached to and incorporated into the lease. It should include:

Description of the approved pet (species, breed, name, weight)
Pet deposit amount and conditions for return
Monthly pet rent (if applicable)
Specific rules (waste, leash, areas)
Tenant acknowledgment of liability for pet-caused damage
Signatures of all adult tenants

Attach a new, updated addendum at every lease renewal. An addendum signed two years ago that was never re-executed at renewal may be unenforceable.

Deposit caps and local rules

Many states cap the total security deposit — including pet deposits — at a fixed multiple of monthly rent (often one to two months). Some states treat pet deposits as part of this cap; others allow separate pet deposits outside the cap.

Before setting your pet deposit amount, check your state's security deposit statute. Collecting more than the cap can result in penalties up to two or three times the excess in some jurisdictions.

What to do when a tenant gets a pet without permission

If a tenant acquires a pet without your approval:

Document the discovery in writing with the date.
Issue a written notice of lease violation referencing the pet clause.
Give the tenant a cure period to either remove the pet or apply for approval through your standard process (if you allow some pets).
If the tenant does not comply, this becomes grounds for lease enforcement per your state's rules.

You cannot immediately revoke a lease over an unauthorized pet without following the notice and cure process your state requires. Skipping that process weakens your position significantly.

Terms worth knowing (plain English)

Pet deposit: a refundable payment held against potential pet-caused damage, separate from the general security deposit in some states.
Pet rent: a non-refundable monthly charge for keeping a pet, in addition to base rent.
ESA (emotional support animal): an animal providing emotional benefit to a person with a disability, protected under the Fair Housing Act.
Service animal: an animal individually trained to perform tasks for a person with a disability, protected under both the FHA and ADA.
Reasonable accommodation: a modification to a landlord's rules or policies required by fair housing law when a tenant has a disability-related need.

Common pet policy mistakes

Saying "no pets" and thinking that covers ESAs and service animals. It does not. You need a separate process for accommodation requests, regardless of your general pet policy.
Charging a pet deposit for an ESA or service animal. This is a fair housing violation. Pet fees of any kind — deposit, rent, or surcharge — cannot be charged for an accommodation animal.
Using a vague addendum. A pet addendum that does not specify the animal, the deposit amount, or the damage liability terms creates gaps that are hard to enforce at move-out.
Not re-executing addendums at renewal. An addendum attached to an expired lease may not carry over automatically. Re-sign it at every renewal.
Ignoring deposit caps. Setting a pet deposit that combined with the general deposit exceeds your state's cap can create legal exposure.

FAQ

Can I refuse to rent to someone with an emotional support animal?

Generally no. ESAs are protected under the Fair Housing Act, and landlords must provide reasonable accommodation unless doing so causes undue hardship or fundamentally alters the housing. A blanket "no pets" policy cannot be used to deny a documented ESA request.

Can I charge a pet deposit for an emotional support animal?

No. Pet deposits, pet fees, and pet rent cannot be charged for an ESA or service animal. These are protected accommodation animals, not pets under fair housing law.

What documentation can I require for an ESA?

You can request a letter from a licensed healthcare provider confirming that the tenant has a disability and that the animal is connected to that disability. You cannot require the animal to be certified or registered, and you cannot ask for a specific diagnosis.

What if a tenant's pet causes damage?

The tenant is responsible for damage caused by any animal in their unit — including ESAs and service animals — beyond normal wear and tear. Document the unit's condition thoroughly at move-in and move-out to support any deductions.

Can I set breed or size restrictions in my pet policy?

Yes, for pets. Breed and size restrictions are generally permissible for standard pets. However, breed and size restrictions cannot be applied to service animals or ESAs — these are accommodation animals and must be considered regardless of breed or size.

What is the difference between a pet deposit and pet rent?

A pet deposit is a refundable sum held against potential damage, returned (less documented deductions) at move-out. Pet rent is a non-refundable monthly charge added to the base rent for the duration of the tenancy. Some landlords charge one, some charge both. Check whether your state limits the total deposit amount before setting a pet deposit.
