The Lease Addendum is a crucial document used in Swiss property law when parties need to modify an existing lease agreement without creating an entirely new contract. It's commonly used for documenting rent adjustments, lease extensions, property modifications, or changes in terms and conditions. The document must comply with Swiss federal law (particularly the Code of Obligations) and cantonal regulations, requiring careful attention to formal requirements and tenant protection provisions. A Lease Addendum helps maintain legal clarity while avoiding the need to draft a completely new lease, making it an efficient tool for both residential and commercial property management in Switzerland.
