ERP Report in France: The Risks & Pollution Report Explained

When selling, renting or buying a property in France, several official diagnostic reports must be provided to inform buyers and tenants of the property’s condition. One of these key documents is the ERP (État des Risques et Pollutions), commonly known as the Risks and Pollution Report.

The ERP determines if a property is in an area prone to natural hazards, environmental risks, or technological risks. Its goal is to ensure buyers and tenants are fully aware of any potential risks associated with the property’s location. This report is part of the Dossier de Diagnostic Technique (DDT), the diagnostic file required for property transactions in France.

What Is the ERP (Risks and Pollution Report)?

The ERP report offers details on natural, environmental, and technological risks associated with a property, based on its geographical location. It uses official data from French authorities and local risk prevention plans to determine whether a property lies within a risk zone and identify relevant hazards. The purpose is to ensure transparency, helping buyers and tenants understand the property’s environmental risks.

What Information Does the ERP Report Contain?

Depending on the location, the ERP may highlight several types of risks identified by the authorities. These can include:

• Natural hazards such as flooding, landslides, earthquakes, avalanches, or forest fires
• Mining risks linked to former mining activity that may affect ground stability
• Technological risks associated with nearby industrial facilities
• Radon exposure, a naturally occurring radioactive gas present in certain regions
• Soil pollution in areas with past industrial activity

Not all risks apply everywhere in France. The report simply reflects the official classification of the commune in which the property is located.

Is the ERP Report Mandatory?

Yes. The ERP is a required document that must be included in the Dossier de Diagnostic Technique (DDT) when selling or renting property in France.

For property sales, the report must be shown to the buyer at the time of signing the preliminary contract (compromis de vente). For rentals, the ERP must be given to the tenant upon signing the lease.

Providing this information promotes transparency during the transaction. If the report is missing or inaccurate, the buyer or tenant may have legal grounds to challenge the agreement.

How Long Is the ERP Report Valid?

The ERP report is valid for six months. Since environmental risk classifications and official prevention plans can change, the document should be up to date when used in a property transaction. Therefore, sellers usually acquire the report shortly before listing the property or finalising a sales agreement.

How to Obtain an ERP Report in France

Obtaining an ERP report is relatively simple. The information is based on official government databases and can be generated online using the property’s address and cadastral details. Many sellers obtain the report through the professional preparing the rest of the diagnostic file. In other cases, the report may be generated directly by:

• the property owner
• a real estate professional
• a diagnostic specialist

The important point is that the report must be based on the latest official risk data available for the commune where the property is located.

What Buyers Should Check in the ERP Report

The ERP provides buyers with valuable insights into a property’s environmental factors, helping them identify potential natural or technological risks nearby. When reviewing the report, buyers should pay attention to information relating to:

• flood risk zones
• forest fire risk, particularly in southern France
• seismic zones in mountainous regions
• technological risks linked to nearby industrial facilities
• radon exposure depending on geological conditions

The presence of a risk classification does not necessarily mean a property is unsafe. However, it may influence insurance conditions, future building regulations, or renovation considerations.

Insurance and Environmental Risks

Environmental risks identified in the ERP report can also affect home and contents insurance. In France, property owners and tenants are generally required to have insurance to cover their property and personal belongings.

Insurers may also consider local environmental risks when assessing coverage. For this reason, buyers and tenants should review the ERP and ensure their home and contents insurance policy offers sufficient protection for the property and its location.

ERP vs Other Property Diagnostics in France

The ERP is often confused with other property diagnostics listed in the DDT, but it has a distinct purpose. While diagnostics such as the energy performance report (DPE), electrical inspection, or asbestos report assess the condition of the building itself, the ERP focuses specifically on external environmental risks related to the property’s location. In simple terms:

• The DPE evaluates the property’s energy efficiency
• Electrical and gas diagnostics assess safety within the building.
• The ERP identifies environmental and technological risks in the surrounding area.

Together, these documents provide buyers and tenants with a complete overview of both the property and its environment.

Regions in France Most Affected by Natural Risks

France’s diverse geography means some regions are more vulnerable to specific environmental hazards. The southern parts and the Mediterranean coast are more susceptible to forest fires and floods during heavy storms. Mountain areas like the Alps and Pyrenees face risks of avalanches, landslides, and earthquakes. River valleys along the Loire, Rhône, and Garonne are prone to flooding, while certain central regions have elevated radon levels due to their geological makeup.

The ERP report accounts for these local conditions, helping buyers understand how geography can affect a property’s environment over time.

The ERP as Part of the French Diagnostic File

The ERP report is just one element of the Dossier de Diagnostic Technique, the set of reports required for property transactions in France. Depending on the age, location, and type of property, the diagnostic file may also include reports covering:

• energy performance (DPE)
• asbestos
• lead
• gas installations
• electrical installations
• termites or other pests

Together, these reports provide transparency and allow buyers and tenants to make informed decisions before completing a property transaction. Whether you’re buying a home in a village, selling a country house, or renting out a holiday home, ensure your ERP is ready and up to date.
