Document background
The Residential Tenancy Agreement Addendum is a crucial document used in Swiss residential property management to formally modify existing lease agreements. It becomes necessary when parties need to document changes to the original lease terms, such as rent adjustments, property modifications, or the addition of new occupants. This document must comply with Swiss federal legislation, particularly the Swiss Code of Obligations and the VMWG, as well as applicable cantonal laws. The addendum serves as a legally binding supplement to the main lease agreement, ensuring that all modifications are properly documented and enforceable under Swiss law. It's commonly used by landlords, property management companies, and tenants when circumstances require changes to the original rental agreement terms.
