The construction law reform planned for 2026 in Switzerland represents a major turning point for property developers. The new provisions significantly increase their liability towards buyers, particularly regarding defect warranties and technical compliance.
Developers will now have to provide more extensive guarantees on the quality of delivered works. Prescription periods for hidden defects are extended, and transparency obligations regarding materials and techniques used are strengthened.
For property owners, this reform represents increased protection. However, it remains essential to engage an independent Owner's Representative to ensure these new obligations are actually respected.
KERLINE SA supports its clients in understanding and applying these new provisions, ensuring that each project benefits from the maximum protections offered by the new legal framework.
