We do not have a separate No Pet addendum, but we do have a paragraph in our lease agreement that may help some.
9. PETS: A. Unless the parties agree otherwise in writing, Tenant may not permit, even temporarily, any pet on the Property (including but not limited to any mammal, reptile, bird, fish, rodent, or insect).
B. If Tenant violates this Paragraph 9 or any agreement to keep a pet on the Property, Landlord may take all or any of the following action:
(1) declare Tenant to be in default of this lease and exercise Landlord's remedies under Paragraph 27;
(2) charge Tenant, as additional rent, an initial amount of $_________ and $_____ per day thereafter per pet for each day Tenant violates the pet restrictions;
(3) remove or cause to be removed any unauthorized pet and deliver it to appropriate local authorities by providing at least 24-hour written notice to Tenant of Landlord's intention to remove the unauthorized pet; and
(4) charge to Tenant the Landlord's cost to:
(a) remove any unauthorized pet;
(b) exterminate the Property for fleas and other insects;
(c) clean and deodorize the Property's carpets and drapes; and
(d) repair any damage to the Property caused by the unauthorized pet.
