Part V: Defects & Warranty

Handling Defects and Guarantees

Even in well-built Swiss apartments, it’s normal for some defects to appear after handover — from scratched tiles to doors that no longer close properly once the building settles.
Understanding how to report and follow up on these issues will save you time and stress.

This chapter explains your rights, responsibilities, and typical procedures under Swiss law and SIA standards.


Under the Swiss Code of Obligations (Art. 367–371 CO), buyers are protected against construction defects for defined periods:

Defect Type Typical Example Warranty Duration
Visible defects Scratches, leaks, missing parts 2 years after handover
Hidden or structural defects Cracks, faulty waterproofing, electrical faults inside walls 5 years after handover

If your contract is based on SIA 118, these same time limits apply, but the procedure for notification and acceptance is more clearly defined.

The warranty period normally starts on the official handover date recorded in the signed acceptance protocol.
