Construction Handover in Geneva: 5 Tips to Secure Your Project Completion in 2026

The handover of the work is the most important legal act of your real estate project. Since January 1, 2026, the legal framework has evolved to better protect clients.

However, in Geneva, signing the handover protocol remains a moment where the buyer is often vulnerable to pressure from contractors.

Understanding the new relationship between the CO and SIA 118

The 2026 revision of the Swiss Code of Obligations (CO) introduced a 60-day period to notify defects. If your contract refers to the SIA 118 standard, you benefit from additional protection.

It is crucial to understand that the 60-day CO period acts as a mandatory safety net. Even if the SIA 118 standard is more flexible, it cannot reduce your fundamental legal rights, as the law prevails over restrictive contractual clauses.

1. Never sign without an exhaustive inspection

Handover is not just an administrative formality. It is your last chance to identify non-conformities before liability becomes complex to prove.

Test every element:

• Water drainage
• Seal integrity
• Functionality of joinery
• Finishes

In Geneva, aesthetic defects are often a sign of underlying structural issues.

2. The protocol: your legal shield

The handover protocol must record every defect, even minor ones. If the contractor promises a quick 'amicable' repair, do not give in, as any defect not recorded in the protocol risks being considered accepted.

Demand that every reservation is dated and accompanied by a precise execution deadline.

3. Vigilance regarding 'revised quotes' and amendments

In 2026, we are seeing an increase in requests to sign liability waivers during end-of-construction interventions. Systematically refuse any clause that would limit your right to warranty for future work.

A revised quote must always be clarified in writing, specifying the exact scope of work to avoid double billing.

4. Payment management and legal mortgages

Never release the final balance without obtaining proof of payment for subcontractors. The legal mortgage of artisans remains a major risk in Geneva.

Ensure that every company has waived in writing its right to register a legal mortgage before paying the final installment.

5. The importance of independent assistance
