Why conduct a PCA before a purchase or renovation?

Buying a house or apartment is often one of the biggest investments you will ever make. However, many buyers focus on visible aspects such as size, location, and charm, without paying enough attention to the technical condition of the building.

This is where the technical audit comes in, an essential step in securing your purchase and avoiding unpleasant surprises.

What is a PCA ? 


A technical audit is an in-depth analysis of the condition of a building, carried out by an independent expert.

Unlike a simple inventory or an EPC certificate, it is not limited to ticking boxes: it aims to understand the overall health of the property.

The expert evaluates the main technical items:

  • building structure and stability,
  • roofing and waterproofing,
  • electrical, gas, and heating installations,
  • joinery, insulation, and energy efficiency,
  • humidity, ventilation, and indoor air quality.

The objective is to identify anomalies, defects, or potential risks, but also to anticipate the work required in the short and medium term.
