Understanding what a pet addendum is can save property owners from costly repairs, reduce legal risk, and help maintain great tenant relationships. It turns general pet rules into specific, legally enforceable terms—covering everything from breed restrictions to pet rent.
At LeaseRunner, we see landlords benefit from them every day. For instance, a landlord might approve a tenant’s Labrador but require proof of vaccinations and a refundable pet deposit before move-in. Or, when taking on a tenant mid-lease who buys a cat, adding a pet agreement addendum clarifies responsibilities immediately.
Quick Facts: What Is a Pet Addendum?
What Is a Pet Addendum in a Lease Agreement?
A pet addendum to a rental agreement is a separate document that modifies the original lease to allow one or more pets under specific conditions. Typically, a pet addendum lists each pet’s type, breed, age, and weight, plus any related fees—such as deposits, non-refundable charges, or monthly pet rent.
For example, a dog addendum might require a $300 deposit and $25 monthly fee, while a cat’s terms may differ. It also outlines tenant duties like leashing, cleaning waste, controlling noise, and may require vaccines or insurance, with variations giving landlords flexibility in setting rules and fees.
In the meantime, a short pet clause in a lease agreement may outline basic rules and conditions regarding pets—such as whether they are allowed—an addendum expands on these by detailing all specific terms, requirements, and expectations.
Example: Without an addendum, a tenant might assume any pet is allowed. But with one, the landlord can specify—“A single dog under 45 lbs., no aggressive breeds, proof of spay/neuter, and $300 refundable deposit."
This clear documentation ensures there’s proof of agreement if a dispute arises. Many landlords decide to use lease agreement templates to create these addendums tailored to their property and state laws.
How Does A Pet Addendum Differ From A Pet Policy Or Pet Clause?
A pet policy in a lease agreement outlines general rules a property follows regarding pets, often shared in marketing materials, tenant handbooks, or brochures, but they are not part of the signed lease. They cover broad rules like “Pets allowed with landlord approval,” but usually do not specify fees, tenant responsibilities, or penalties.
A pet clause in a lease agreement is a short section embedded in the main lease.
It may say something like “Pets allowed” or “No pets except with landlord consent.” Although it is part of the signed lease, this pet clause in the lease agreement often lacks detailed terms about pet care, deposits, noise limits, or enforcement procedures. This can make it hard to enforce rules if problems arise.
A pet addendum, however, is standalone. Both landlords and tenants sign it. It specifies the animal, care responsibilities, cleaning rules, deposits, and penalties. Think of it as closing the loopholes that a broad pet policy may leave open.
In Summary:
- Pet Policy: General, broad rules not part of the lease, usually found in brochures, not signed.
- Pet Clause: A Brief statement within the lease, signed, but lacks specifics and enforcement power.
- Pet Addendum: Separate, signed document, legally binding with clear terms and conditions.
It is also important to understand that service and emotional support animals (ESAs) are not legally considered pets. They are exempt from the pet addendum and pet policy restrictions. Landlords must make accommodations for these animals regardless of any pet rules in place.
This clear distinction helps landlords create enforceable agreements and avoid misunderstandings while complying with relevant laws.
Common Situations Where a Pet Addendum Is Needed
There are many times when adding a pet agreement addendum is the smart move for landlords. It protects the property, meets legal needs, and keeps pet rules clear.
- Tenant Gets a Pet Mid-Lease
Sometimes tenants bring pets into the rental after signing a lease that initially bans animals. For example, Sarah’s lease bans pets. Three months later, she adopts a cat. Instead of breaking the lease, both parties sign a pet addendum on lease to the rental agreement.
It lists simple rules—keep the litter box clean, repair pet damage, and control noise. This keeps the lease valid and avoids conflict.
- Lease Has No Pet Clause
If your contract is silent on pets, confusion can arise. Adding a lease agreement for pets addendum states which pets are allowed, fee amounts, and any size or breed rules.
- Changing to Pet-Friendly
A landlord may change a no-pet property to allow pets. Using a comprehensive pet addendum with clear rules on cleaning, pet deposits, and liability insurance helps communicate expectations. This clarity reduces tenant concerns and protects property cleanliness and safety.
- Shared Housing
If only one tenant in a shared unit owns a pet, name that person in the pet clause in the lease agreement. This ensures they handle clean-up and repairs.
- Insurance Rule Change
When insurance companies update policies, landlords might need to restrict certain breeds or require vet records for coverage. Updating the pet policy in the lease agreement or adding a pet agreement addendum reflecting these rules ensures compliance with insurer demands. Get a claer understanding at out article on pet liability insurance for renter.
For example, new policies may prevent coverage for certain large or aggressive breeds, so the addendum must clearly notify tenants of these restrictions.
Why Landlords Should Include a Pet Agreement?
Allowing pets in rentals can attract more renters, but it also has risks. For instance, your pets can cause damage, liability, noise, and legal issues; a clear pet agreement addendum protects property, defines rules, reduces disputes, and ensures enforceable, fair rental policies.
Therefore, a clear and detailed pet agreement helps landlords protect their property while keeping good tenant relationships. Here’s why every landlord should include one.
Protect Your Property
Pets can cause damage like chewed door frames, stained carpets, or scratched floors. A well-written pet agreement says the renter is responsible for fixing and paying for pet damage.
If a dog scratches the floor, the renter pays for repair or replacement. This stops landlords from facing costly repairs when the lease ends.
Avoid Misunderstandings
Without a formal agreement, renters might think they can have many pets or pets of any kind or size. By adding limits—like one dog under 40 lbs. allowed—a pet agreement avoids confusion. It also states rules for pet behavior, noise, and waste cleanup.
A renter can't claim the right to keep an unapproved aggressive breed or multiple cats if it's restricted. This keeps arguments from starting.
Reduce Liability
A clear pet clause helps define the renter's responsibility for injuries caused by pets. If a renter’s dog bites someone, the agreement can state that the renter must cover medical costs or legal claims. Adding this lowers the landlord’s risk. Renters may need renters' insurance for pet incidents.
Set Clear Expectations
Landlords can use a pet policy agreement to set rules about quiet hours to lower noise, leash rules in hallways, and cleanliness.
Renters must throw away pet waste and not let animals roam common spaces without supervision, which helps everyone live in peace and hygiene.
Enforce Terms in Court
A signed pet agreement is legally binding, unlike informal rules or talks. Landlords can act if renters break pet rules, like having unapproved pets or not paying pet rent.
Attract Good Renters
Pet-friendly rentals with clear, fair pet rules attract good renters. Pet owners like clear policies and might stay longer, which cuts turnover and vacancy costs.
Adding a detailed and clear pet agreement gives landlords control, protects their property, and improves landlord-renter relationships. For tools, check out resources for a legally correct pet agreement.
Legal Considerations for Pet Addendums in the US
Understanding pet laws is key for landlords in the US when making a pet agreement for rentals. Federal and state' landlord-tenant rules come first, so knowing them prevents legal problems and keeps things fair for renters.
Federal Laws (FHA, ADA, ESA)
The Fair Housing Act (FHA) protects renters with disabilities who need service or Emotional Support Animals (ESAs). Landlords can’t say no to housing, have breed limits, or charge extra for these animals.
The Americans with Disabilities Act (ADA) also says service animals can go anywhere, including rentals. Like, even if your lease says “no pets,” you have to let a renter have a guide dog and not charge extra.
You can ask for simple proof for an ESA or service animal, but not private health info. This keeps the renter's privacy but checks that the animal is legit.
State-Specific Pet Addendum Rules
Each state has its own rules for pet fees, deposits, and limits. Some states don’t allow non-refundable pet fees. Others don’t let you ban certain breeds unless your insurance says so.
For example, in California, you can’t ban pit bulls unless your insurance requires you to. Texas lets you charge pet deposits, but sets a limit on how much. Checking state laws keeps your pet rules valid. It also helps you write a pet clause for a lease agreement that fits local rules.
When You Cannot Restrict Pets (Service & Emotional Support Animals)
Even a strict “no pets” rule can’t stop a real ESA or service animal. These animals aren’t seen as pets under federal law—they’re seen as tools for help.
If a renter with an ESA moves into a “no pet” place, you have to allow the animal without extra charges. You can ask for a note from a doctor, but not details about their health issues. Charging extra or saying no can cause housing complaints or legal trouble.
Key Elements of a Strong Pet Addendum
It’s really important for landlords to have a solid pet addendum for their rental agreements. This way, everyone knows the pet rules and can act accordingly.
The addendum should cover things such as who the tenant and pet are, what the costs are, what is expected in terms of care, and what happens if rules aren't followed. This makes responsibilities clear for everyone.
1. Tenant & Landlord Identification
Start by writing down the full legal names of the landlord and tenant, plus the address of the rental. This makes sure the addendum is linked to the right lease and people. For example: Landlord: John Doe; Tenant: Jane Smith; Property: 1234 Oak Street, Apt 5 B.
2. Detailed Pet Description (Type, Breed, Weight, Age)
List each pet’s type (like dog, cat, or bird), breed, weight, age, and any unique marks or microchip numbers. This stops tenants from switching pets without asking. For example: One Labrador Retriever, 45 lbs, 3 years old, microchip ID #123456789.
3. Pet Deposits, Non-Refundable Fees, and Monthly Pet Rent
Note any pet deposits, one-time fees, or monthly pet rent. Say if the deposit can be returned and what conditions apply.
For example: Tenant pays a $300 refundable pet deposit and $25 each month for pet rent. The deposit is returned if the pet doesn't cause any damage.
4. Behavior & Care Rules (Noise, Damage, Cleanliness)
Add rules about pet behavior, such as keeping noise down, who pays for damage, and how clean things should be. For example, the tenant must stop the pet from barking too much. All waste must be cleaned up quickly from shared areas and the apartment.
5. Insurance Requirements for Tenants with Pets
Landlords often want tenants to have renters' insurance that covers pet issues. Mention how much coverage is needed and if the landlord should be listed on the policy.
6. Consequences for Violations
Specify what occurs if a tenant breaches the pet addendum, such as fines, termination of the lease, or removal of the pet. Your example: If the tenant has not obtained permission for the pet or has not kept the unit clean, the tenant will incur a $200 fine for either violation and possible eviction.
Including these provisions in your pet addendum helps protect your property, reduce risk, and address pets professionally. By using pet agreement addendum templates from LeaseRunner, you will make sure your written contract covers all the important provisions and includes each landlord's rights and responsibilities.
How to Write and Create a Pet Addendum?
As a landlord, it's important to write and create a clear, well-written pet addendum to the rental agreement so that you can properly oversee pet ownership while still protecting your property.
A well-drafted addendum will include as many details as you can think of, so that both the landlord and tenant understand their rights and responsibilities. Below is an easy-to-follow, straightforward step-by-step process to prepare a pet agreement addendum.
Step 1: Identify Parties & Property
The first step is to clearly identify the landlord's name and the tenant's name exactly as they appear on the original lease. Additionally, you should properly identify the rental property location in detail. This helps connect the pet addendum to the lease and its occupants.
For example: "Landlord: John Smith; Tenant: Emily Johnson; Property: 234 Elm Street, Apartment 3A".
This matching language about who is party to the agreement will help avoid confusion about which lease the addendum amends, and ensure all parties know who the tenant is and agree to the terms.
Step 2: Describe the Pet
The second step is to properly identify each pet that is allowed in detail. You should identify the type of pet (e.g., dog, cat, bird), breed (e.g., mixed), gender (e.g., male), age, weight, and other identifying marks (e.g., microchip or license numbers). For example: "One neutered male beagle, 22 lbs., license #A12345".
If you want to clearly identify a pet, you should avoid leaving it ambiguous, so that the tenant cannot easily switch out a different pet or multiple pets without the landlord's consent. If allowed, pets must be described in separate sentences.
Step 3: Set Fees & Deposits
Clearly state the amount of all pet fees, deposits–refundable and non-refundable–as well as monthly pet rent. An example would be: “Tenant agrees to pay a $300 refundable pet deposit and $25 pet rent per month.” Indicate under what circumstances fees would be collected, and how tenants would be refunded.
For additional information, please see our article on whether pet deposits are refundable, which goes into more detail about the reasons for collecting deposits and the legal limits.
Being transparent about fees upfront prevents disputes down the line and ensures tenants know what their financial obligations are before signing a lease.
Step 4: List Tenant Obligations
Outline of the roles and responsibilities of the tenant once they acquire a pet, which encompasses both the care of the pet itself and the care of the property.
There should be an expectation for the tenant to keep their pet's vaccination and vet records up to date, to have routine flea/tick prevention programs established, and to repair any damage to the property, including any damage made by their pet, immediately.
For example: “Tenant must provide yearly vaccination records, and have a flea control program in place. The tenant must repair or replace anything the pet damaged, including carpet, flooring, and doors."
You may want to note the tenant’s obligation to limit noise and keep the property clean, specifically picking up pet waste and mitigating excessive barking.
Step 5: Liability & Indemnity
Add liability clauses that make the tenant liable for any injuries or damages that arise from the pet. For example, you might write: “Tenant accepts full liability for any injury, harm, or damage to property caused by the pet, and agrees to indemnify and hold harmless the landlord.”
You may also want to add a provision where the tenant is required to maintain renters insurance with coverage for all pet-related liabilities, and add the landlord as an additional insured, which further protects your interests.
Step 6: Compliance & Removal
Outline the reasons upon which pets must be removed, including: repeated noise complaints, aggressive behavior, or whatever other prescribed care rules that have been violated.
For instance: “If there are indications that the pet is showing aggressive behavior, or is in violation of any terms of this addendum, the landlord may demand removal upon written notice.”
The reason for stating these terms is to allow a landlord to take immediate action to remove a pet from the rental property, but in doing so, they clearly told the tenant the terms under which action could be taken.
Step 7: Signatures & Dates
Finally, both the landlord and tenant must sign and date the addendum, acknowledging that all terms are accepted and assumed by both parties. The signatures will render the document enforceable. Without signatures, it is more difficult to enforce.

Risks of Allowing Pets Without a Pet Addendum
When allowing pets in rentals, failing to complete a strong pet agreement exposes landlords to risks. A pet agreement establishes protections for a landlord's property, clarifies the responsibilities and expectations for renters. Here's what happens if you don't have a pet agreement, with examples:
Property Damage
Pets sometimes cause damage. Dogs might scratch floors or chew woodwork, and cats could damage carpets or drapes. Without an agreement, getting renters to pay for damages can be hard.
For example, a renter might dispute responsibility for floor scratches unless the agreement states otherwise. Specifying repair responsibilities and pet deposit rules prevents unexpected costs.
Increased Liability
If a tenant's pet injures someone, your lawsuit risk increases. If a dog bites a visitor and there's no pet clause in the lease, you could face medical or legal issues.
A strong pet agreement requires renters to carry insurance for pet-related injuries, cutting your risk. By stating the renter is liable, you gain extra protection against potential lawsuits.
Noise and Nuisance Complaints
Pets can create noise or odors that disturb neighbors. Without clear pet care and noise rules in the lease, problems can continue. Imagine a dog barking constantly or a tenant not cleaning up after a pet, causing neighbor complaints.
Setting noise limits, waste cleanup rules, and pet behavior expectations allows better standard enforcement.
Difficulty Enforcing Pet Rules
When pet regulations are stated vaguely or informally, it becomes impossible to enforce them. Renters will likely argue whether they “got" the authorization for a pet, as well as how many and what sort of pets they are allowed to have.
And if the agreement was never written down, enforcing some sort of compliance in these situations is hard work and virtually impossible.
The pet agreement should specify which animals are authorized, how many, and any other restrictions by breed/species, thus making compliance that much easier.
Allergy and Pest Issues
No pet regulations will tend to flush up complaints about allergies, or other pest problems associated with pets, such as fleas or ticks. In cases where they are allergic to animals, tenants could be looking at serious health complications with no clear cleaning instructions being enforced.
A great pet agreement would discuss cleaning stipulations, flea treatment stipulations prior to renting to them, or stipulations for the job of pest control.
Legal and Fair Housing Compliance Risks
Unintentionally discriminating against an assistance animal, or service animal, by requiring payment, or having excessive restrictions, may lead a landlord to serious violations of federal mandates.
Not having a clearly defined/explained lease regarding these animals can lead a landlord to a fair housing complaint or court action. Landlords owe it to themselves to research and understand federal and state rules that are applicable when drafting a pet agreement that will stand the test of legal scrutiny.
In summary, a solidly written and legally sound pet agreement affords landlords the risk mitigation, protection of their investment, and maintenance of a good landlord-tenant relationship.
Conclusion
