Introduction
Selling a property in Chaville, Viroflay, or Ville d’Avray is not improvised. Beyond valuation and marketing, every seller must comply with a series of mandatory real estate diagnostics. This essential step, governed by strict regulations, aims to ensure transparency, security, and trust between seller and buyer. At GUY HOQUET CHAVILLE - VIROFLAY, we know that these procedures can seem complex. Our local experience and personalized support allow us to approach this step with complete peace of mind. Discover in this article everything you need to know about mandatory real estate diagnostics during a sale, to prepare your project effectively and with peace of mind.
Why are real estate diagnostics mandatory during a sale?
When an owner decides to sell their apartment or house, they must provide the buyer with a complete technical diagnostics file (DDT). This obligation, provided by law, aims to inform the buyer about the general condition of the property, anticipate potential risks (safety, health, environment), and protect the parties against potential disputes later on. The mandatory diagnostics vary according to the nature of the property, its age, its location, and changes in regulations. They are essential to secure the transaction, reassure the buyer, and guarantee a sale in compliance with current legislation (gouvernement.fr - Mandatory real estate diagnostics).
At GUY HOQUET CHAVILLE - VIROFLAY, we support our clients at every stage, from selecting diagnostics to compiling the file, to streamline the sale and avoid any unpleasant surprises on the day of signing.
The main real estate diagnostics required in Chaville and surrounding areas
The content of the DDT depends on several factors, but some diagnostics are recurrent in most sales in Chaville, Viroflay, and nearby areas:
- Energy performance diagnostic (DPE): mandatory for any built property, it informs about energy consumption and the impact on greenhouse gas emissions. A clear DPE is a real asset to reassure buyers sensitive to energy-saving issues (ADEME - Understanding the DPE).
- Asbestos diagnostic: concerns properties for which the building permit was issued before July 1997, to prevent risks related to asbestos exposure.
- Lead exposure risk report (CREP): required for properties built before 1949, it aims to detect the presence of lead in paints.
- Termite diagnostic: mandatory in areas defined by prefectural order, particularly for certain municipalities in Île-de-France (Service-public.fr - Termite diagnostic).
- State of the internal electrical and gas installation: to be provided for any installation over 15 years old.
- Non-collective sanitation diagnostic: for properties not connected to the public network.
- Carrez law diagnostic: for co-owned properties, it guarantees the exact private area.
The list can expand depending on the configuration of the housing or changes in regulations. Expert support ensures the compliance of the file and the seller's peace of mind.
Clarifications on regulations and seller responsibilities
The legislation surrounding real estate diagnostics evolves regularly, with a constant strengthening of buyer protection. It is the seller's responsibility to provide valid documents, carried out by certified diagnosticians. In the absence of a mandatory diagnostic, or if it proves to be erroneous, the seller's liability may be engaged after the sale, with significant financial consequences (price reduction, sale cancellation, damages).
At GUY HOQUET CHAVILLE - VIROFLAY, we ensure the accuracy of each technical file and select recognized diagnostic partners for our clients. Our mission: prevent risks, secure the transaction, and support you in a transparent and reassuring process.

Recent developments and perspectives on regulations
The regulatory framework for real estate diagnostics is constantly evolving. The energy performance diagnostic (DPE) has been strengthened to combat energy-inefficient properties and encourage energy renovation, directly impacting the rental and sale conditions of the least efficient properties. Complementary measures are regularly introduced to enhance transparency regarding exposure to natural, mining, or technological risks, particularly in certain areas of Île-de-France (Géorisques - Information for buyers and tenants).
