## What a Pet addendum is

A pet addendum adds a specific pet to an existing lease. It names the pet, sets any deposit, fee or monthly pet rent, and lists the rules the tenant agrees to. Assistance animals, including emotional support animals, are not pets under fair housing law, and most landlords may not charge pet fees for them.

## Every field

| Field | What goes in it |
| --- | --- |
| Lease | The landlord, every tenant on the lease, the address and the date of the original lease. |
| Pet | Name, type and breed, weight, age, color and a license or vaccination tag number. |
| Charges | A refundable pet deposit, a one-time fee, monthly pet rent, or a mix. Many states cap deposits; check yours. |
| Rules | Control, cleanup, vaccinations, noise and who pays for damage. Add anything specific, such as no pets in the pool area. |
| Signatures | Landlord and every tenant, with the date. |

## Mistakes that get it sent back

- **Charging for an assistance animal.** Under the Fair Housing Act, assistance animals are not pets. Use a reasonable accommodation process instead of this addendum.
- **Only one tenant signs.** Every tenant on the lease should sign, since all of them are responsible for damage.
- **No description of the pet.** Without breed, weight and a tag number, a second dog can arrive under the same addendum.

## FAQ

**Can every tenant sign from their phone?**

Yes. Fill in the details, choose Request signatures, and add each tenant and yourself. Everyone signs on their phone and you get a certificate of completion.

**Can I autofill it from the lease?**

Yes. Add the lease as the source in Autofill and the names, address and date carry over.
