Lease and pet documents

Pet Addendum

Add one named pet to an existing lease with agreed responsibilities and signature lines for the landlord and every tenant.

Available with limits Updated on October 16, 2026

Available with limits: this version does not include pet deposit, pet fee or pet rent clauses because limits vary by state and city and have not been reviewed. The addendum says those terms must be agreed separately in writing. Assistance animals are not covered; the tool stops and points to the accommodation request instead.

Before you start

Good fit

When to use

  • A tenant wants to keep a pet in a rental whose lease says nothing about pets, or says no pets, and the landlord is willing to allow one named animal in writing.
  • A landlord allows pets and wants the animal, the tenant responsibilities and the signatures recorded in a document attached to the lease.
  • A pet was allowed informally and both sides now want the arrangement in writing before a renewal or a change of manager.
  • A second tenant is moving in with an animal and the existing lease needs an addendum rather than a new lease.

Choose another route

When not to use

  • The animal is an assistance animal that a tenant needs because of a disability. That is a reasonable accommodation request, not a pet, and pet fees, pet deposits and pet rules do not automatically apply. The tool stops and points to the Assistance-Animal Accommodation Request.
  • You want the document to set a pet deposit, a pet fee or monthly pet rent. This version leaves those clauses out because limits vary by state and city and have not been reviewed; agree any payment separately in writing after checking the rules for your location.
  • You are writing a new lease. An addendum attaches to a lease that already exists; the lease itself needs its own document.
  • A landlord wants to remove a pet that is already permitted, or a tenant is facing a notice about an animal. That is a dispute, not an addendum; read the lease and get local advice.

Prepare first

What you need

  • The date of the existing lease, the landlord and tenant names as they appear on it, and the rental address.
  • Whether the animal is a pet or an assistance animal.
  • A description of the animal: type, breed or description, name, and optionally age, weight, whether it is spayed or neutered, whether vaccination records were provided, and a license number if your city requires one.
  • The date the addendum takes effect and the responsibilities both sides have agreed to, with any other agreed terms in plain sentences.
  • Whether to include a neutral clause allowing the landlord to withdraw consent for documented violations after written notice, as the lease allows.
  • The name of the person signing for the landlord and the name of each tenant who will sign.

What this document is

A pet addendum is a short agreement attached to an existing lease. It names one animal, records the responsibilities the tenant takes on for it, and states how the addendum fits with the lease. It is signed by the landlord and by every tenant on the lease. Unlike a notice, it does nothing until both sides sign.

The generator builds the addendum from the facts you enter: the lease date and parties, the rental address, a description of the animal, the agreed responsibilities, an optional set of other terms, and the names of the people signing. The clauses are numbered so either side can refer to them later.

What it covers and what it leaves out

The document contains a permission clause for the one described animal, a responsibilities clause built from the items you tick, a damage clause that defers to the lease, a clause that no other animal may be kept without written consent, the effective date and term, an optional withdrawal-of-consent clause, a sentence that assistance animals are handled separately, and an entire-agreement clause that keeps the rest of the lease in force.

It deliberately leaves out pet deposits, pet fees and pet rent. Those charges are regulated differently from place to place, and we have not reviewed the limits across states and cities. The addendum says in plain words that any such payment is not addressed and must be agreed separately in writing. It never prints an amount.

Fees, deposits and pet rent

If you and the other side agree on a payment, put it in a separate written agreement after reading an official page for your state and, where one exists, your city. The notes beside the preview show a source-checked note where an editor has opened an official publication. For California, the Department of Real Estate’s tenant guide says a pet deposit counts toward the overall security deposit limit; the note cites the page. Everywhere else, the note says plainly that we have not checked.

Assistance animals

An animal that a tenant needs because of a disability is not a pet. A request to keep one is a request for a reasonable accommodation, and pet fees, pet deposits and breed rules do not automatically apply. The first step asks which situation you are in. If you choose assistance animal, the tool stops, explains why, and links to the Assistance-Animal Accommodation Request and to official fair housing resources. We would rather stop than produce a document that looks routine but is wrong for the situation.

Signing it

Both sides sign and date. Each tenant on the lease gets a separate signature line, because an addendum signed by only some tenants may not bind the others. Printed names should match the lease. An electronic signature is not automatically suitable for every document; if you use one, keep the completed copy and the signing record. Then attach the signed addendum to the lease and make sure each party has a complete copy.

After it is signed

Take dated photos of the unit, including floors, doors, trim and any yard, on or before the effective date. If vaccination records were provided, keep a copy with the addendum. If your city or county requires a pet license, record the number before signing and keep the license current. If you later agree on a deposit, fee or pet rent, write it in a separate signed agreement so the paper trail stays clear.

Pet Addendum to Lease

This Pet Addendum (the "Addendum") is entered into between Cedar Row Rentals LLC ("Landlord") and Jordan Ellis ("Tenant"). It is attached to and made part of the lease dated March 1, 2026 (the "Lease") for the rental unit at 88 Sample Court, Apt 2, Fresno, CA 93721 (the "Premises"). Capitalized terms not defined here have the meaning given in the Lease.

Terms

1. Permission. Landlord consents to Tenant keeping the one animal described above (the "Animal") at the Premises, subject to the Lease and this Addendum. This consent applies only to the Animal described above and does not extend to any other animal.

2. Tenant responsibilities. While the Animal is kept at the Premises, Tenant agrees to:

  • keep the Animal on a leash or in a carrier, and under control, in all common areas of the building and grounds.
  • clean up and properly dispose of the Animal's waste right away, inside the unit and anywhere on the property.
  • prevent the Animal from making noise that disturbs other residents or neighbors.
  • prevent the Animal from damaging the Premises, the building or the grounds, and report any damage to Landlord promptly.
  • keep the Animal free of fleas, ticks and other pests, and treat the unit promptly if an infestation occurs.

3. Damage. Tenant is responsible for damage to the Premises, the building or the grounds caused by the Animal, as provided in the Lease. This Addendum does not change how the Lease handles damage, repairs, cleaning or the security deposit.

4. Pet deposit, pet fee and pet rent. Any pet deposit, pet fee or pet rent is not addressed in this addendum and must be agreed separately in writing. This Addendum does not set, confirm or waive any such amount.

5. No additional animals. Tenant will not keep, board or foster any other animal at the Premises, even temporarily, without Landlord's prior written consent. Offspring of the Animal are not covered by this Addendum.

6. Term. This Addendum takes effect on November 1, 2026 and continues for as long as the Lease, including any renewal or extension, unless it is ended by a written agreement signed by Landlord and Tenant or consent is withdrawn as described in the next clause.

7. Withdrawal of consent. If Tenant does not meet the responsibilities in this Addendum, Landlord may withdraw consent for the Animal by giving Tenant written notice that describes the problem and the time allowed to correct it, as the Lease and applicable law allow. If the problem is not corrected within the time stated in the notice, Tenant agrees to remove the Animal from the Premises by the date stated in the notice. The rest of the Lease is not affected by a withdrawal of consent under this clause.

8. Assistance animals. This Addendum covers a pet. It does not apply to an animal that Tenant needs because of a disability and that is permitted as a reasonable accommodation. A request of that kind is handled separately from this Addendum.

9. Entire agreement and conflict with the Lease. This Addendum and the Lease contain the whole agreement between Landlord and Tenant about the Animal. If this Addendum and the Lease conflict about the Animal, this Addendum controls. In every other respect the Lease remains in full effect and all of its other terms continue to apply.

Each person signing below confirms that they have read this Addendum and agree to it.

California

California: a pet deposit counts toward the security deposit limit

The California Department of Real Estate tenant guide (2026 edition) that we checked on 2026-10-16 says that a payment called a pet deposit is treated as part of the security deposit whatever it is called, and that as of July 1, 2024 the total security deposit a landlord may require is limited to one month of rent for furnished and unfurnished units, with no separate allowance for pet deposits, key fees or cleaning fees. Only small landlords as defined in the guide (individuals or LLCs owned by individuals renting one or two properties with no more than four units in total) may charge up to two months of rent, and a DRE news page adds that this does not apply when the tenant is a service member. The guide does not discuss monthly pet rent. This is an editorial source check of a state publication, not legal review, and it is one reason this tool does not write a deposit amount for you. The statute itself, Civil Code section 1950.5, could not be opened during our check.

Delivery checklist

Read the delivery guide

How a letter is delivered and what you keep often matters as much as what it says.

The guide How to deliver a rental letter and keep a copy covers hand delivery, certified mail and email, and what a usable record looks like. The generator shows a checklist based on your answers at the review step; this is the general version.

  • Have the landlord and every tenant sign and date the addendum, and give each party a complete signed copy.
  • Attach the signed addendum to the lease and keep them together; note the lease date on both.
  • Take dated photos of the unit, including floors, doors, trim and any yard, on or before the effective date, so later damage questions have a starting point.
  • If vaccination records were provided, keep a copy with the addendum and note the date they were given.
  • If you agreed to a pet deposit, pet fee or pet rent, write it in a separate signed agreement after checking the rules for your state and city; this addendum does not include it.
  • Check whether your city or county requires a pet license and, if so, record the number on the addendum before signing.

Questions about this agreement

Why does the addendum not include a pet deposit, pet fee or pet rent?

Because whether those charges are allowed, and how much, depends on your state and sometimes your city, and we have not reviewed those limits across the country. In California, for example, an official state guide says a pet deposit counts toward the overall security deposit limit. Rather than print a number that might be wrong where you live, the addendum states that any pet deposit, pet fee or pet rent is not addressed in it and must be agreed separately in writing. If you agree on a payment, write it in a separate signed agreement after checking an official page for your state and city.

What if the animal is an assistance animal?

Then this is the wrong document. An animal that a tenant needs because of a disability is handled as a request for a reasonable accommodation under fair housing rules, not as a pet, and pet fees, pet deposits and pet rules do not automatically apply. If you choose "This is an assistance animal" in the first step, the tool stops and points you to the Assistance-Animal Accommodation Request and to official fair housing resources. It does not produce a pet addendum for that situation.

Can the addendum restrict breeds or sizes?

The addendum covers one named animal described by type, breed or description, name and, if you add them, age and weight. It does not contain a general breed or weight policy. Some cities, counties, buildings, homeowner associations and insurance policies have their own breed or size rules, and a few states limit what local governments may do. We do not list them. Check with local animal services and your building rules before signing, and describe the animal accurately.

The lease says no pets. Does the addendum override that?

A signed addendum is the usual way to make an exception to a no-pets clause for one named animal. The document says that where it conflicts with the lease about the animal, the addendum controls, and that the lease otherwise stays in full effect. It changes nothing until the landlord and every tenant on the lease have signed it. A landlord is not required to agree to a pet, and a tenant should not bring the animal in before the addendum is signed.

Who signs, and can we sign electronically?

The person signing for the landlord and every tenant on the lease. Each tenant gets a separate signature line with a date line; an addendum signed by only some tenants may not bind the others. Many parties sign on paper and exchange copies. An electronic signature is not automatically suitable for every document; if you sign electronically, keep the completed copy and the signing record, and sign on paper if either side prefers. Whatever you choose, attach the signed addendum to the lease.

Can the landlord revoke permission later?

Only if the addendum or the lease allows it. The tool offers an optional clause, written in neutral terms, under which the landlord may withdraw consent for documented violations after written notice that describes the problem and the time allowed to correct it, as the lease and applicable law allow. The lease and local law decide what notice is enough; the addendum does not set a number of days. If you leave the clause out, the addendum can be ended only by a written agreement signed by both sides.

What happens if the pet causes damage?

The addendum says the tenant is responsible for damage caused by the animal as provided in the lease, and that it does not change how the lease handles damage, repairs, cleaning or the security deposit. It does not create a separate damage charge or a cleaning fee. Dated photos of the unit on or before the effective date give both sides a starting point if a question comes up later.

We have two pets. Can one addendum cover both?

This version describes one animal and says no other animal may be kept without the landlord's prior written consent. For a second animal, generate a second addendum with its own description, or ask the landlord to list both animals in one signed document. Offspring of the described animal are not covered either, so a litter needs its own written consent.
