Document background
The Rental Contract Addendum serves as a crucial legal instrument in Swiss property law for modifying existing rental agreements without the need to draft an entirely new contract. It is commonly used when parties need to implement changes such as rent adjustments, property modifications, or term extensions while maintaining the core structure of the original agreement. This document type must comply with Swiss federal legislation, particularly the Code of Obligations (OR/CO) and the Ordinance on Rental and Lease of Residential and Business Premises (VMWG/OBLF), as well as applicable cantonal laws. The addendum is essential for both residential and commercial properties, providing a clear record of agreed modifications while ensuring legal compliance and protecting both parties' interests.
Suggested Sections

1. Parties: Identification of landlord and tenant with full legal names and addresses

2. Background: Reference to the original rental agreement including its date and subject matter, and general context for the modifications

3. Definitions: Key terms used in the addendum, including reference to definitions from the original agreement that remain applicable

4. Amendments to Original Agreement: Clear statement of specific modifications being made to the original rental agreement

5. Effective Date: Specification of when the modifications take effect

6. Confirmation of Other Terms: Statement confirming that all other terms of the original agreement remain unchanged

7. Signatures: Execution block for all parties to sign, including date and place of signature

Optional Sections

1. Rent Adjustment: Required when the addendum involves changes to rent amount or payment terms

2. Property Modifications: Used when the addendum covers changes to the rental property or permitted uses

3. Term Extension: Included when modifying the duration of the rental agreement

4. Additional Occupants: Required when adding or removing authorized occupants

5. New House Rules: Used when implementing changes to building or property rules

6. Maintenance Responsibilities: Included when modifying maintenance or repair obligations

7. Utilities and Services: Used when changing responsibility for or access to utilities and services

Suggested Schedules

1. Schedule 1 - Modified Terms: Detailed listing of specific clauses being modified, showing both original and new text

2. Schedule 2 - Rent Calculation: If rent is being modified, detailed breakdown of new rent calculation

3. Schedule 3 - Property Modifications: Plans, specifications or descriptions of any authorized property changes

4. Appendix A - Official Forms: Any required official forms under Swiss law (e.g., rent increase forms)

5. Appendix B - Supporting Documents: Any relevant supporting documentation referenced in the addendum
