MANDATORY DIAGNOSTICS GUIDE IN CONDOMINIUM DWELLINGS AND DETACHED HOUSES
There are a total of 9 mandatory technical diagnoses (Property Surveys) to be conducted when selling or renting out your property.

A mandatory copy will also be required by the notary office.

1. Energy Performance Diagnosis (EPD)
The EPD was introduced in 2006 as part of the European directive in improving the energy performance of buildings. It has become a tool for households to inform the state about their energy consumption and an essential benchmark for public energy and housing policy, which is used in particular to identify energy sieves (for example, properties with labels F and G of the DPE consume the most energy).
A second reform set by the ELAN Law of 2018 (law on the evolution of housing, development, and digital), was instituted back on July 1, 2021. This overhaul is part of a broader context of accelerating the energy renovation of buildings. The DPE serves as one of the key tools for this reform (i.e. information for potential buyers of a property, support for financial aid and bonds, etc.).

2. Finding of risk of exposure to lead (CREP)
Lead is usually present in older paints.
The CREP (or Lead Diagnosis) consists of measuring the lead concentration of the paint coatings in your property and describing their state of conservation.

3. State mentioning the presence or absence of asbestos
Asbestos refers to harmful fibers often found in construction or renovation projects in real estate.
Checking for asbestos, also called the asbestos diagnosis, mentions the presence or absence of asbestos in materials or products of your property.

4. Condition of the indoor electricity installation (if the installation is more than 15 years old)
If the electricity installation inside your property is more than 15 years old, you'll need to conduct an indoor electricity installation diagnosis.
The survey gives an overview of the safety of the electrical installations on your property.

5. Condition of the indoor gas installation (if the installation is more than 15 years old)
The gas diagnosis gives an overview of the current state and safety of indoor gas installations in homes.

6. Condition of the non-collective sanitation facility (only for individual houses)
When a property is not connected to the public wastewater collection network, it must be equipped with a non-collective sewerage facility. This installation is subject to an inspection carried out by the municipality. The control results in a diagnosis that is also part of the mandatory technical diagnostics.

7. Termite status
The diagnosis communicates information on the presence or absence of xylophagous insects (in particular, termites) on a property.

8. State of risks and pollution (natural, mining, technological, seismic, radon, etc.)
The Risk and Pollution Assessment informs prospective buyers and tenants of the natural, mining, technological, seismic, radon, and soil pollution risks that the property may be exposed to.

9. Noise diagnosis
The noise diagnosis is a document that informs future buyers of the existence of possible noise pollution. If the property you want to sell is near an airport (a place called the airport noise zone), you'll need to conduct an audible diagnosis.
