Building Surveys in France

Building Surveys The French have a different approach to building surveys as you many find in your own country.

It is not common for the French buyer to have a survey done due to the diagnostics report which occurs at a later stage of the sale.

How French building surveys work

Although it is uncommon for the French buyer to have a building survey, most foreigners will have one. In France, you cannot make a sale subject to a building survey, these must be done before you put an offer in on the property - prices are much more negotiable before your offer rather than after. There is a list of tests that the vendor must pay for and have undertaken by professionals, called the Dossier de Diagnostic Technique (DDT). This report will include:

  • Natural mining or technological risk - any risks the property may be prone to, such as earthquakes, erosion or flooding.
  • Energy efficiency - to give you a general idea of the cost of heating, if needed, and energy consumption.
  • Gas Instillation this applies to systems over 15 years old.
  • A Foss report - this is to check the septic tanks are up to European standards. The law on septic tanks have changed in recent years and many tanks are 10-15 years old meaning that more than likely will not meet these new standards. If the tank does not conform to standards, you will need to sign off with the notaire that you will make the tank meet the standards within 18 months of buying the property. If the agent tells you the tanks do not conform, the price of the property will usually reflect this. However, if the agent claims the tanks meet the standards are met and then the report shows otherwise, then there will be room for negotiation as septic tanks can be expensive.
  • Lead – This is to make you aware if lead paint has been used on window shutters, to ensure a mask is warn if they need stripping. This would not be a reason to pull out from a sale or renegotiate prices.
  • Electrics – Electrics are slightly different in France and a full report will be given as to what will need to be done.
  • Asbestos – A lot of old farm buildings may have asbestos on the roof, so the report is to make you aware of where this may be and if you want to dispose of anything with asbestos, the correct disposal rules must be followed.
  • Termites / Woodworm – It is not very common for the property to have termites, however this is treatable. The test must be valid within three months so if the sale were to be elongated past the three months, a new test would have to be done. Termites is a valid reason for you to pull out of the sale.

Most sellers wait until they have an offer agreed before commissioning the reports, some of which have a short “shelf life” before they need to be undertaken again. If you would like a more comprehensive survey you will find plenty of RICS registered surveyors offering a service throughout France. 

FAQs: Building Surveys in France

Are building surveys compulsory when buying property in France?

No, full structural surveys like those in the UK are not compulsory in France. However, sellers must provide a set of mandatory diagnostic reports (diagnostics immobiliers), covering issues such as asbestos, lead, termites, gas, electricity, energy performance, and septic tanks.

What are the mandatory property reports in France?

The Dossier de Diagnostic Technique (DDT) must be provided by the seller and includes checks for energy performance (DPE), asbestos in older buildings, lead in paintwork, termites and pests in certain regions, gas and electrical safety, and septic tank compliance. These reports are required before the final sales contract is signed and give buyers a clear picture of the property’s condition.

Should I commission a full building survey in France?

It is strongly recommended, especially for older or rural properties. Unlike the mandatory diagnostics, a full survey checks structural integrity, roof condition, damp, and renovation needs. Many international buyers hire independent surveyors for peace of mind.

How do I find a qualified surveyor in France?

Independent building surveyors are available, though less common than in the UK. Look for English-speaking surveyors with experience in French property, often found through expat networks, relocation services, or specialist firms.

What does a building survey in France cost?

Costs vary depending on the property’s size and location but typically range from €500 to €1,500. More detailed structural reports or specialist inspections may cost more.

Are surveys common in rural France?

Yes. Surveys are particularly important in rural or older village properties, which may have hidden structural issues, outdated electrics, or non-compliant septic systems. Renovation buyers should always commission a detailed report.

Do notaries in France check the property’s condition?

No. The notary’s role is legal and administrative — registering the sale, ensuring ownership transfer, and collecting taxes. They do not check the physical condition of the property, which is why private surveys are advisable.

Can I use a UK surveyor for a French property?

Yes, some UK-based surveyors operate in France or travel for inspections, but make sure they are familiar with French construction methods and building regulations.
