Buying off-plan in Geneva: which contractual clauses to check before signing?

Buying off-plan, or purchasing a property under construction (PPE) in Geneva, is a major milestone for any buyer. While the project may look perfect on paper, the reality of the construction site can lead to costly surprises.

As a buyer, you are not a construction professional, and the sales contract is often drafted to protect the developer's interests. Before committing, a rigorous analysis of the contractual clauses is essential to secure your investment.

The importance of technical specifications and plans

The sales contract is not limited to the price and the surface area. The technical description is the reference document that defines the quality of materials, equipment, and finishes.

Too often, vague terms like "standard quality materials" allow companies to cut costs at the buyer's expense. Verify that every element is precisely described:

• Type of flooring
• Brand of sanitary ware
• Performance of insulation

If a feature is not explicitly mentioned, it is not guaranteed. Demand detailed plans and ensure that the stated surfaces correspond to the actual living space, not just a commercial surface area.

Price clauses and budget overruns

One of the major fears when buying off-plan in Geneva is budget overruns. Ensure that the sales price is firm and final.

If the contract includes price revisions linked to the evolution of material costs, these must be strictly regulated and justified. Beware of "extras" or amendments that can quickly inflate the final bill.

An expert budget must include a margin for contingencies and finishing choices from the start to avoid being trapped when you have the least room for maneuver.

Guarantees and delivery deadlines

Delivery delay is a classic risk. Your contract must include a precise delivery date, accompanied by clear and applicable delay penalties.

Furthermore, pay close attention to guarantees. In Switzerland, SIA 118 standards often govern contractual relations. Ensure that the limitation periods for construction defects are clearly stipulated and that you have an effective recourse in case of defects discovered during the handover of the work.
