Are you looking to buy a new property off-plan and want to check the reliability of the developer? A common reflex is to type “blacklist of real estate developers” into a search engine. The problem is that this official blacklist does not exist in France. There is no unique public register maintained by the State that lists developers to avoid. So how can you protect yourself before signing?
Why there is no official blacklist of developers in France
In financial matters, the Autorité des marchés financiers (AMF) publishes blacklists of unauthorized actors offering investments. These lists are available online and updated regularly. They cover financial investments, crowdfunding, and crypto-assets.
Real estate development, however, does not fall under the same framework. No French authority maintains a blacklist of real estate developers. The sector is regulated by the Code de la construction et de l’habitation (CCH), but there is no equivalent of the AMF list for builders or developers of new housing.
Websites that offer “blacklists” of developers are editorial content based on customer reviews or feedback. This information can be useful, but it has no regulatory value. It is neither verified by an authority nor exhaustive.
A developer absent from these lists can pose a problem, and vice versa. To access the blacklist of real estate developers in France as it circulates online, keep this limitation in mind and do not rely on it as your only source.

Checking a real estate developer: reliable sources to cross-reference
Since there is no centralized register, the verification relies on you. Have you noticed that a developer displays beautiful images and enticing promises on their website? The challenge is to look beyond the commercial facade.
Registration and professional qualification
First step: verify that the developer is properly registered. The commercial register (accessible via Infogreffe or the commercial court’s website) allows you to confirm the legal existence of the company. An unregistered developer or one in collective proceedings is an immediate warning sign.
You can also check their membership in the Fédération des Promoteurs Immobiliers (FPI), which imposes an ethical framework on its members. This is not an absolute guarantee, but it is an additional filter.
Judicial decisions and administrative sanctions
Courts regularly issue decisions involving developers, particularly regarding disputes related to delivery delays, defects, or non-compliance with guarantees. These decisions are public.
Cross-referencing judicial decisions with sanctions from competent authorities remains the most reliable method. The real estate sector is monitored, particularly through anti-money laundering (LCB-FT) obligations, and sanctions are imposed on professionals who do not comply.
Customer reviews and specialized forums
Online reviews, on Google, real estate forums, or social media, provide a trend. A developer accumulating complaints on the same issues (repeated delays, shoddy finishes, absent customer service) deserves increased scrutiny. Read detailed reviews rather than overall ratings.
Legal guarantees: what the developer must provide before the sale
The law protects the buyer in VEFA (sale in future state of completion) through several mechanisms. Knowing these guarantees helps identify a developer who seeks to evade them.
- Financial completion guarantee (GFA): the developer must prove that a financial institution guarantees the completion of the project, even in case of failure. Without this document, do not sign.
- Perfect completion guarantee: it covers defects reported within a year following delivery. The developer is required to correct them.
- Ten-year guarantee: it covers damages compromising the building’s solidity or rendering it unfit for its intended use, for ten years after the completion of the work.
- The right of withdrawal: the buyer has a legal period to withdraw from their commitment after signing the reservation contract, which provides additional protection.
A developer who hesitates to provide the GFA or delays its presentation is a clear warning sign.

Sanctions and professional bans in real estate development
Article L.241-3 of the Code de la construction et de l’habitation provides for professional bans for certain serious offenses.
Specifically, a developer convicted of violating the CCH may be prohibited from exercising their activity. These bans are not compiled in a public file accessible to individuals. One must refer to published court decisions or consult a specialized lawyer to identify them.
Practical method to secure a purchase in real estate development
Instead of looking for a miracle list, adopt a structured approach before each investment project:
- Check the registration of the developer and their history (seniority, delivered projects, any collective proceedings)
- Consult customer reviews on multiple platforms, prioritizing detailed feedback on delivery and customer service
- Require the financial completion guarantee before any signature, and keep a copy
- Search for any judicial decisions involving the developer, through legal databases or a lawyer
- Ensure that the reservation contract complies with current regulatory obligations, particularly regarding real estate solicitation
The best protection remains cross-referencing multiple sources: official registers, case law, online reviews, and document verification. No website can replace this approach, because no authority centralizes information on the reliability of developers in France. This is a gap in the system, and as long as it persists, individual vigilance remains the only true safeguard.
