To be accompanied by Insula Réa
The seller of a property has certain obligations toward the buyer. It is important to have the inspections conducted as soon as the property is listed for sale to ensure the buyer is fully informed.
While these inspections are mandatory, they are provided for informational purposes only. Even if the seller provides inspection reports with positive findings or that reveal non-compliance issues, this does not prevent the sale from proceeding.
Depending on the type of property, its year of construction, and its location, the technical inspections required for a real estate sale may vary.
Diagnoses, One by One
01
Energy Performance Assessment
Assess your property's energy consumption and CO₂ emissions. Rating scale from A (excellent) to G (poor energy efficiency). Required upon publication of the real estate listing.
02
Energy Audit
A detailed report (30 to 50 pages) outlining the work needed to improve the property’s energy efficiency. This is required in addition to the Energy Performance Certificate (EPC) for energy-inefficient homes.
03
Asbestos Inspection
Détecte la présence d'amiante dans les matériaux de construction (flocages, dalles, toitures). L'amiante est interdit depuis 1997 mais reste présent dans de nombreuses maisons rétaises anciennes.
04
Lead Exposure Risk Assessment
Recherche la présence de plomb dans les peintures anciennes (risque de saturnisme). Concerne principalement les maisons de caractère et les bâtisses historiques de l'île de Ré.
05
Electrical Inspection
Vérifie la conformité et la sécurité de l'installation électrique. Contrôle 102 points dont le tableau électrique, les prises, les liaisons équipotentielles et les circuits de recharge.
06
Gas Inspection
Assesses the condition and safety of gas systems. Checks piping, connections, and ventilation to prevent any risk of leaks or carbon monoxide poisoning.
07
Diagnostic Termites
Détecte la présence de termites souterrains dans les bois de structure. En Charente-Maritime, l'intégralité du département est classée zone infestée depuis l'arrêté préfectoral de 2002 — île de Ré comprise.
08
État des Risques et Pollutions
Informe l'acheteur des risques naturels et technologiques liés à la localisation du bien. À l'île de Ré : risques de submersion marine, érosion côtière, zones Natura 2000. Gratuit sur georisques.gouv.fr.
09
Assainissement Non Collectif
Contrôle la conformité du système d'assainissement autonome (fosse septique, micro-station). Certaines propriétés rurales de l'île de Ré, notamment dans les communes moins urbanisées, sont concernées.
THE UNIQUE FEATURES OF THE ÎLE DE RÉ
Termites — Tout le département 17
By Prefectural Order No. 17-196 of 2002, the entire Charente-Maritime department, including its islands, is designated as a contaminated area. A termite inspection is required for all sales, without exception.
ERP — Risques côtiers spécifiques
The Île de Ré is subject to specific natural hazards: coastal flooding, coastal erosion, and storms. The emergency response plan must take these risks into account and be updated every 6 months.
Dry rot — Not required
There is no prefectural ordinance regarding dry rot in Charente-Maritime. This inspection is therefore not required on the Île de Ré, unlike in certain departments in Brittany or Normandy.
Older Homes — Asbestos Is Common
The housing stock on the Île de Ré is mostly older. Most properties are subject to asbestos inspections (for buildings with permits issued before 1997) and, in some cases, lead inspections (for buildings with permits issued before 1949).
IN 4 simple steps
01
Contact a diagnostic technician
Choisissez un professionnel certifié (accréditation COFRAC obligatoire). Prévoyez 2 à 3 semaines avant la mise en vente.
02
Perform the diagnostics
An on-site visit lasting 2 to 4 hours, depending on the size of the property. The inspector will provide you with the reports within 48–72 hours.
03
Form the DDT
Regroupez l'ensemble des diagnostics dans le Dossier de Diagnostic Technique, à annexer au compromis de vente.
04
Vendez en toute sérénité
Un DDT complet rassure l'acheteur, sécurise la transaction et protège le vendeur contre les recours pour vices cachés.
Frequently Asked Questions
A building’s ENERGY PERFORMANCE CERTIFICATE (DPE) assesses its ability to use energy efficiently to provide thermal comfort (heating and air conditioning), lighting, ventilation, and hot water.
The Energy Performance Certificate (DPE) provides information on the energy and climate performance of a residence or building (labels A through G) by assessing its energy consumption and its impact in terms of greenhouse gas (GHG) emissions.
With certain exceptions (see Article R. 126-15 of the French Building and Housing Code), an EPC is required when a residence or building is sold, when a lease agreement for a residence or residential building is signed, and for new buildings.
The “Climate and Resilience” Act, published on August 24, 2021, makes it mandatory, effective April 1, 2023, an energy audit must be conducted when selling a single-family home or a single-owner apartment building with an Energy Performance Certificate (DPE) rated Class F or G. This requirement also applies as of January 1, 2025, for properties rated Class E, and as of 2034 for residential properties rated Class D.
No. Energy Performance Certificates (EPCs) issued before July 1, 2021, are no longer valid as of January 1, 2025. You must have a new EPC issued using the revised, legally enforceable, and reliable calculation method.
The seller is responsible for the costs of the inspections. For a primary residence, these costs are deductible from the sale price when calculating capital gains on real estate. For a rental property, these costs are deductible from property income under the actual income method.
Yes, it is still possible to sell a property classified as G. However, a mandatory energy audit must be included with the DDT, and this property can no longer be rented out as of January 2025. The audit outlines the work that needs to be done to improve the energy efficiency rating.
Yes, without exception. Prefectural Order No. 17-196 of 2002 classifies the entire Charente-Maritime department, including the islands, as a termite-infested area. It applies to every municipality on the Île de Ré. It is valid for only 6 months and must be renewed if the sale takes a long time.
