Asbestos in French homes is regulated

In France, it is legal to sell a house containing asbestos, but the process is strictly regulated. If the building permit was issued before July 1, 1997, an asbestos diagnosis is required and must be included in the technical diagnosis file (DDT) provided to the buyer during the sales agreement signing.

Asbestos was commonly used in construction

Asbestos is a fibrous mineral that was widely used in construction before the 1990s due to its insulating properties, fire resistance, and low cost. In older homes, it can be found in roofs, corrugated sheets, slates, or under-roof materials, though its use has been banned in France since 1997.

Health risks from asbestos exposure

The primary danger of asbestos comes from inhaling its fibers, which can lead to serious respiratory diseases such as asbestosis or certain cancers. Health risks are most significant when asbestos-containing materials degrade and release fibers into the air, making it essential to assess their condition before a sale.

Legal requirements for asbestos diagnosis

Before selling a house with an asbestos-containing roof, the owner must have a diagnosis performed by a certified professional. This document identifies whether asbestos is present, its location, and its condition. If the material is in poor condition, the report may recommend removal or monitoring, and this information must be included in the DDT provided to the buyer.

Asbestos removal is not always required

French law does not require asbestos removal before a sale unless the diagnosis shows the material is in an advanced state of degradation and poses an immediate health risk. In such cases, local authorities may mandate removal or containment. Otherwise, the sale can proceed as long as the buyer is fully informed, though decontamination is a complex and expensive process requiring specialized companies.

Asbestos can affect property value

The presence of asbestos can lower a house's market value, as buyers often negotiate a lower price or request the seller to cover decontamination costs. However, if the roof is in good condition and the diagnosis does not recommend immediate removal, the property may still be attractive. Insurers may also impose specific conditions for homes containing asbestos, making it important to inform the buyer of all potential consequences.
