A pet addendum adds pet terms to a lease that is already running, without rewriting the lease. It is the document to use when the answer to "can I keep a cat?" is yes and both sides want the terms recorded.

Who this document is for

  • A landlord allowing a pet after the lease was signed
  • A tenant asking to add a pet mid-tenancy
  • A landlord setting pet rent, a deposit, or rules for a specific animal

When to use something else

Using the wrong document is the most expensive mistake in this category, because the paperwork looks complete while doing the wrong thing. This is not the document for:

  • A new lease — pet terms belong in the lease itself
  • Assistance animals, which are treated differently from pets under housing rules
  • Removing a pet from a tenancy — that is a lease violation matter

What the generated document contains

  • The lease being amended, by date
  • The specific animal — type, breed, weight, name
  • Pet deposit or pet rent, if any
  • Rules on waste, noise, damage and common areas
  • Who is responsible for damage the animal causes
  • Signature block for both parties

State and local requirements

Requirements for this document differ by state, and sometimes by city. Notice periods, deposit limits, permitted fees and required disclosures are all set locally, and a number that is correct in one state can be wrong in the next one.

This page does not state those figures. The questionnaire asks you for the values that apply to your tenancy and prints what you enter, so the document reflects your situation rather than a national average. Start with the state lease pages for the jurisdiction you are renting in.

Frequently asked questions

No. A deposit is held and may be returned; pet rent is a recurring charge that is not. Some jurisdictions limit or prohibit one, the other, or both, so check locally before setting either. The addendum records what you agree.

Generally no. Assistance animals are usually treated as a disability accommodation rather than as pets, and pet fees and pet rules commonly do not apply to them. This addendum is for pets, and you should take advice before applying pet terms to an assistance animal.

If the lease prohibits pets, the tenant generally needs permission to keep one. This addendum exists for the case where permission is given and the terms are agreed — putting it in writing protects both sides.

The addendum states it explicitly, because the lease may only address damage generally. Being specific avoids the argument later about whether a scratched floor was ordinary wear.

Yes, and that is deliberate. Permission for "a dog" is not permission for a second one. Naming the animal keeps the agreement about the pet actually discussed.
