Building Expert in Nice and Antibes — VEFA Inspections, Crack Analysis, Litigation Support
Cassini Expertise is an independent building expert based in Antibes, providing technical inspections and litigation support throughout the Alpes-Maritimes (06), including Nice (06000, 06100, 06200, 06300). We deliver bilingual (English/French) reports for property buyers, owners, developers, and lawyers, combining local knowledge with technical rigour to assess construction quality, diagnose defects, and support legal proceedings before the tribunaux judiciaires of Nice and Grasse, and the Cour d’Appel of Aix-en-Provence.
Nice, as the capital of the French Riviera, presents a diverse building stock: Belle Époque villas in Cimiez and Mont-Boron, modern apartment blocks in the city centre, waterfront developments along the Promenade des Anglais, and hillside constructions in Fabron, Gairaut, and Sainte-Marguerite. Each typology—whether historic masonry, reinforced concrete, or contemporary steel-frame—requires tailored inspection methods. Our expertise covers structural integrity, compliance with French construction standards (DTU, NF norms), and the legal guarantees applicable under French law.
VEFA (Off-Plan) Inspections — Pré-Réception and Réception
For buyers of new-build apartments or houses sold under the VEFA regime (Vente en l’État Futur d’Achèvement, governed by articles L. 261-1 and following of the Code de la construction et de l’habitation), Cassini Expertise conducts detailed inspections at the critical handover stages: pré-réception (pre-handover visit) and réception (formal acceptance). We identify visible defects—uneven tiling, poorly fitted windows or doors, inadequate waterproofing in bathrooms and balconies, non-compliant electrical installations—before the buyer signs the procès-verbal de réception, which triggers the legal guarantees.
Our method includes:
- Systematic room-by-room inspection with photographic documentation.
- Verification of conformity with the specifications (notice descriptive) and applicable DTU (Documents Techniques Unifiés).
- Drafting of a detailed snagging list (liste de réserves) with technical references, enabling the buyer to withhold up to 5% of the purchase price until defects are remedied (article L. 262-1).
- Follow-up inspection to confirm completion of remedial works.
We also conduct the one-year inspection under the garantie de parfait achèvement (article 1792-6 of the Code civil), which obliges the builder to repair all defects notified within one year of handover. This inspection is crucial to catch issues that emerge after occupation—plumbing leaks, shrinkage cracks, door misalignment—before the guarantee expires.
Crack Analysis and Structural Assessment
Structural cracks are a frequent concern in Nice, particularly in hillside areas built on clay or marl soils prone to shrink-swell movement (retrait-gonflement des argiles, or RGA). The phenomenon is exacerbated by seasonal drought and is recognised as a natural disaster (catastrophe naturelle) under the CatNat regime when officially declared by ministerial decree.
Our crack diagnosis follows the classification method set out in French standard NF P 95-201, which distinguishes cracks by width, pattern, and structural significance:
- Microcracks (< 0.2 mm): generally superficial, affecting finishes only.
- Fine cracks (0.2–2 mm): may indicate thermal movement or minor settlement; monitoring advised.
- Cracks (> 2 mm): potentially structural, requiring investigation of foundations and soil conditions.
Our on-site assessment includes:
- Detailed cartography of all cracks (location, orientation, width) using a fissuromètre (crack-width gauge).
- Installation of witnesses (témoins) to monitor crack progression over time.
- Analysis of the building’s foundations, subsoil type, and drainage conditions.
- Review of any geotechnical reports and historical subsidence data for the neighbourhood.
We determine whether the damage is cosmetic or indicative of foundation movement, and we establish the causal link between soil shrinkage and cracking—essential for insurance claims under the CatNat regime (which requires a ministerial decree and a ten-day claim window) or for action under the ten-year structural guarantee (garantie décennale, article 1792 of the Code civil) if the builder is at fault.
Our written report provides a technical classification, identifies the probable causes, assesses the structural risk, and estimates repair costs (underpinning, micropiles, crack sealing, façade rendering). It can be used to support an amicable settlement with insurers or developers, or as evidence in litigation before the tribunal judiciaire.
Pre-Purchase Surveys and Building Condition Reports
Whether you are acquiring a period villa in Cimiez, a modern apartment in Libération, or a hillside house in Gairaut, an independent building survey protects you from hidden defects. French law distinguishes between vices apparents (patent defects, which the buyer should have noticed) and vices cachés (latent defects, governed by article 1641 of the Code civil). A thorough pre-purchase inspection reduces the risk of costly surprises after completion.
Our survey covers:
- Structural elements: walls, floors, roof structure, foundations.
- Exterior envelope: façades, rendering, balconies, terraces, waterproofing.
- Roof covering and rainwater disposal (gutters, downpipes).
- Interior finishes: floors, walls, ceilings, joinery.
- Services installations (visual inspection only; specialist diagnostics—electrical, gas, asbestos, lead—are separate).
- Evidence of moisture ingress, wood-boring insects, or past settlement.
We provide a written report in English or French, with photographs, a risk assessment, and cost estimates for remedial works. This enables informed negotiation on price or contract conditions.
Litigation Support and Expert Witness Services
Cassini Expertise assists lawyers, insurers, and property owners in construction disputes, providing technical expertise for amicable settlement or court proceedings. We act as technical consultants (sapiteur) or as court-appointed experts (expert judiciaire) before the tribunaux judiciaires of Nice and Grasse and the Cour d’Appel of Aix-en-Provence.
Our litigation work includes:
- Counter-expertise of damage reports prepared by insurers or opposing parties.
- Technical analysis of liability under the legal guarantees: garantie de parfait achèvement (one year, article 1792-6), garantie de bon fonctionnement (two years for equipment, article 1792-3), and garantie décennale (ten years for structural damage, article 1792).
- Assessment of compliance with French construction standards (DTU) and the obligations under article 1792-1 (builder’s duty to deliver a defect-free building).
- Drafting of technical reports admissible in court, with precise references to applicable norms and case law.
- Attendance at site meetings and court hearings to explain findings and respond to technical questions.
We do not act as advocates—our role is strictly technical—but our independence and rigour provide robust evidence to support legal claims or defences.
Party Wall and Easement Analysis
In densely built areas of Nice and hillside properties, disputes over party walls (murs mitoyens) and shared easements (servitudes) often arise. Cassini Expertise provides technical analysis to clarify ownership, maintenance obligations, and rights of access or drainage, supporting amicable resolution or litigation through detailed review of deeds, cadastral records, and on-site inspection. We do not perform formal boundary surveying—that is reserved for licensed land surveyors—but our expert opinions on structural responsibility and encroachment can strengthen your legal position before the tribunal judiciaire.
