Diagnostic Reports

Reports currently in the DDT (Dossier de Diagnostic Technique) cover the following areas:

Lead

A report on the presence, if any, of lead-based paint – only required on properties built prior to 1 January 1949. There is no requirement to identify or report on the presence of lead pipes in the property.

Asbestos

A report on the presence, if any, of materials or products containing asbestos – only required on properties built prior to I July 1997.

Termites

A report on the presence, if any, of termites and other similar destructive pests. This report is required only in certain specified areas of of the country, particularly the south west of France.

Electrical

A report on the state of the indoor electrical installation where the wiring is more than 15 years old.

Gas

A report on the state of the gas installation if it is more than 15 years old.

Energy efficiency

An assessment of the energy performance of the property to give the future owner some idea of the likely level of energy consumption and heating costs. The property is rated A to G to reflect the annual level of energy consumption and greenhouse gas emissions. For properties assessed as having the lowest ratings an energy audit must also be carried out to provide information on the renovation works required to improve the rating. Properties with the lowest rating are not allowed to be used for letting purposes.

Natural Risks and Pollution

A report is required in those communes where a risk prevention plan is in place or is in preparation, or in those areas classified as at risk of seismic movement or other classified natural or technological disaster. It must state, for instance, whether or not the property is located in a flood zone, an area prone to earthquakes, major storms, avalanches, subject to ground movement, near a dangerous factory, if there is exposure to radon, or in proximity to major lorry routes where dangerous materials are being transported. It must also state if the property is located in a designated ‘noise’ zone, e.g. near an airport.

Drainage

A report has to be obtained, usually from SPANC (Service Public d’Assainissement Non Collectif), on the state of the drainage disposal arrangements if the property is not connected to a public sewer. This report will say whether the drainage arrangements are deemed satisfactory; if they are not satisfactory the incoming owner is required to bring them up to contemporary standards within a period of 12 months.

Radon

A report is required in areas where there is a known risk of radon. Radon is a radioactive gas that occurs naturally. It has no taste, smell or colour, and special devices are needed in order to detect it. Radon rises from certain types of subsoil into the air, but when it is trapped inside an enclosed space, concentrations can build up and can pose a serious risk to health by damaging lung tissues.

Geotechnical

A geotechnical study is required in relation to the sale of land in areas where it is considered there is a moderate or high risk from ground movement.
