Real estate diagnosis: condition of the non-communal sewage facility

Where a dwelling is not connected to the public sewage collection system, it must be equipped with a self-contained non-collective sewage treatment plant. This plant must be subject to inspection by the municipality.

The test results in a diagnosis called Status of the non-communal sewage facility.

If sold, the seller must integrate this diagnosis with the various diagnostics included in the Technical Diagnostic Record (DDT) and deliver it to the purchaser.

You must have a "sanitation" diagnosis carried out in case of sale of a house not connected to the public wastewater collection network if there is not yet a network or if the connection is technically not feasible.

Before the sale, you need to have your installation checked.

To do this, you must contact the public non-collective sanitation service (SPANC) of your municipality to agree on an appointment.

The contact details of the SPANC are available in town hall.

SPANC controls your installation.

It delivers a diagnosis indicating whether or not your installation presents malfunctions and/or risks to health or the environment.

In case of problems found, you will have to do some work to bring the installation into conformity.

This work to bring the installation into conformity is at your expense.

You can still decide not to do them.

In this case, you must inform the future buyer who will decide whether or not to acquire the property as it is.

The work can then be part of the financial negotiation.

In all cases, they must be made at the latest 1 year after the signature of the deed of sale.

The commune gives you the diagnosis.

You must integrate this diagnosis with the various diagnostics included in the Technical Diagnostic Record (DDT).

You must give the DDT to the buyer at the time of the signature of the promise to sell or at the deed of sale.

The diagnosis must be less than 3 years old at the time of signing the promise to sell or the deed of sale.
