For condominium lots , only the installation present in the private portion must be diagnosed.
The diagnosis is carried out by a professional diagnostician.
The diagnosis of the indoor electricity installation is valid for 3 years.
It is inserted in the technical diagnostic file attached to the compromise (or promise) and then to the authentic deed of sale.
