If a tenant wishes to have a pet in a rental property, they should request and sign a Pet Addendum with the landlord before bringing the pet onto the premises. See the most common pet addendum examples to include in a rental lease agreement.5) Tenants agree to clean up after their pet and to dispose of their pet's waste properly and quickly. A pet addendum gives permission to allow the tenant to have pets on the rental property. It requires the tenant will be responsible for their pet(s). Tenant(s) may keep up to two (2) pets in the home. The pets must not be on the "restricted breeds list" (see below). Download a pet addendum to a lease template to allow a tenant to have a pet in a rental property and establish the rules they must follow. You will be required to complete a PET SCREENING. A Pet Agreement must be signed and returned after the PET SCREENING is completed.
