The Addendum Lease Agreement Template is essential when parties need to modify an existing lease without creating an entirely new agreement. This document is commonly used across the United States when circumstances change during a lease term, such as rent adjustments, addition of occupants, or modification of property use terms. It must comply with federal regulations like the Fair Housing Act, as well as state-specific landlord-tenant laws. The addendum becomes legally binding once signed and serves as an extension of the original lease agreement, maintaining all unmodified terms while clearly stating the agreed changes.
