by oonakivisto
When a rental's terms change mid-lease, a lease addendum records the update without rewriting the whole agreement. This collection of 41 templates helps landlords and tenants add pet clauses, extensions, occupant changes, and new rules to an existing lease in a clean, official way.
Each addendum is editable in Microsoft Word, ready for the change, the date, and both signatures. Attach it to the original lease and keep copies for everyone involved. Landlord-tenant rules vary by state, so confirm local requirements before you rely on one. Download the template that fits your change and keep the lease current.

What is a lease addendum and when do you need one?
A lease addendum is a document that adds to or changes the terms of an existing lease without rewriting it. You need one when something changes mid-lease, such as adding a pet, extending the term, changing occupants, or introducing new rules, while keeping the original agreement intact.
What is the difference between a lease addendum and a lease amendment?
A lease addendum adds new terms or clauses to a lease, covering topics not in the original. A lease amendment changes existing terms, such as adjusting rent or dates. Both modify the agreement, but an addendum supplements while an amendment alters what was already written.
What should a lease addendum include to be valid?
A lease addendum should reference the original lease by date and address, clearly state the new or changed terms, and note that all other lease provisions remain in effect. It should be dated and signed by both landlord and tenant so the change is documented and enforceable.
