Why building expertise is essential in 2026
In 2026, the construction sector across the Alpes-Maritimes and the Var is undergoing major change. Between tighter environmental standards (the reinforced RE2020), rising material costs and natural hazards (earthquake, flooding, wildfire), calling in a building expert is no longer optional \u2014 it’s a necessity. Whether you’re a homeowner with a self-build project or a real estate professional, an independent survey secures your investment and lets you get ahead of technical issues before they become costly.
What a thorough survey actually covers
Our firm, Cassini Expertise, works across the entire coastline and hinterland of Provence. Here is what we systematically check:
- Regulatory compliance: adherence to local zoning plans (PLU), seismic standards (PACA sits in zone 4) and accessibility rules.
- Structural diagnosis: foundations, load-bearing walls, roof framing \u2014 essential given the clay soils prone to shrink-swell movement.
- Energy performance: insulation, air-tightness, heating systems \u2014 to meet RE2020 requirements.
- Natural hazard management: soil studies, drainage, wildfire protection in classified zones.
- Material quality: traceability and resistance to the Mediterranean climate (UV, salt spray, mistral wind).
What owners and professionals gain from it
For a homeowner, a 2026 building survey is peace of mind. It lets you:
- Spot hidden defects before buying or selling.
- Negotiate the price with full knowledge of the property’s condition.
- Secure bank financing more easily \u2014 lenders often require an expert report.
For professionals (developers, architects, builders), a survey is a risk-management tool: it reduces disputes, improves build quality, and makes it easier to secure decennial liability insurance.

When should I call in a building expert for a new-build project?
