Sale of building land: the vendor's guarantee in the event of refusal of planning permission

Imagine: you have just bought a plot of land in Bobigny to build a seven-storey building, hoping to make a profitable property development. You sign the deed of sale, obtain a loan, hire an architect. But a few months later, the town hall refuses your planning permission. The reason? The land is too small for the project, or it is located in a non-building zone. You are left with land you cannot do anything with, and loan repayments to make. What can you do?

This situation, more common than one might think, raises a central legal question: must the seller of building land guarantee that the land is suitable for the project specified in the contract? The answer is not always obvious, because preliminary sale agreements and notarised deeds often contain clauses that limit the seller's liability. But a 1977 decision of the Court of Cassation clarified this point in favour of buyers. Here is an explanation.

In this judgment, the highest French court ruled that the seller of a communal plot, who had undertaken to build a 17-storey apartment block with 104 flats, had to guarantee that the land was suitable for that project. Since planning permission had been refused by the prefect because of the location and dimensions of the project, the Court ordered rescission of the sale (annulment), considering that the thing sold was unfit for the use for which it was intended. In other words, the seller cannot hide behind the refusal of the administration to escape its obligations.

The facts: a story that happens every day

In 1972, a local authority sold a plot of land to a construction company, Bourdin et Chaussé. The tender specifications stated that the buyer undertook to build a 17-storey apartment block with 104 flats. The company paid the price and obtained a loan. Relying on this promise, it applied for planning permission. But the prefect refused, on the grounds that the project was incompatible with the planning rules in force (in particular height and density).

The company then sued the local authority to obtain rescission of the sale (annulment) and damages. The local authority defended itself: planning permission was refused for planning reasons, which was an administrative risk beyond its control. Moreover, the tender specifications contained a forfeiture clause (a clause that cancels the sale if permission is refused), but the company had not invoked it within the required time.

The Court of Appeal ruled in favour of the company: it ordered rescission of the sale and condemned the local authority to repay the price and pay damages. The local authority appealed to the Court of Cassation. The Court of Cassation dismissed its appeal and upheld the Court of Appeal's judgment. For the judges, the seller had guaranteed the size of the constructions possible on the plot. The refusal of planning permission revealed that the land was unfit for the intended use, which justified rescission.

The reasoning of the court — explained

The judges' reasoning rests on two legal pillars: the guarantee against latent defects (Article 1641 of the Civil Code) and contractual liability (Article 1240 of the Civil Code, formerly 1382). In short, the seller must deliver a thing that conforms to what was promised. If it turns out that the land does not allow the construction of the project described in the contract, that is a latent defect (a hidden defect that makes the thing unfit for its use).

The local authority argued that the refusal of planning permission was an unforeseeable event, an administrative 'force majeure'. But the Court replied that, in the tender specifications, the local authority had itself defined the construction project. It cannot therefore invoke its own imprudence or an external circumstance to escape its obligations. However, the solution is not automatic. It presupposes that the contract refers to a specific construction project, as was the case here. What few people know is that if the contract merely sells a 'building plot' without specifying the project, the seller is not required to guarantee the obtaining of planning permission for any project.

The Court also upheld the amount of damages awarded to the buyer: architect's fees, loan interest, loss of chance. In other words, the seller cannot simply repay the price; it must also compensate the losses suffered by the buyer who in good faith believed he could build.

What this means for you — practically

For buyers of building land, this decision is a valuable protection. If you buy a plot with a specific construction project defined in the deed (for example, 'construction of a 120 m² villa with swimming pool') and planning permission is refused for a reason related to the land (non-building status, easement, undersizing), you can request rescission of the sale and damages.

For sellers, the message is clear: you must ensure that the land is indeed suitable for the announced project. If you sell a plot in Boulogne-Billancourt claiming that a 5-storey building can be built on it, but the Local Urban Plan (PLU) limits the height to 3 storeys, you incur liability. undefined, I have come across cases where private sellers, poorly informed, had to repay not only the price but also the notary's fees, architect's fees and the buyer's bank penalties. For example, a plot sold for €200,000 in Bobigny ultimately cost the seller €250,000 after repayment and damages.

For tenants or co-owners, this decision has less direct impact, but it illustrates a general principle: contractual promises bind the person who makes them. If a developer sells you an off-plan apartment advertising facilities that are not authorised by the planning permission, you can also take action.

Four tips to avoid this type of dispute

• Check the Local Urban Plan (PLU) before buying: Go to the town hall or consult the PLU online. Make sure the land is building land and that the rules (height, footprint, use) match your project. Do not rely solely on the seller's statements.
• Make the sale subject to a condition precedent of obtaining planning permission: In your preliminary sale agreement, include a clause making the sale conditional on obtaining planning permission in accordance with the project. If permission is refused, you can recover your deposit without cost.
• Describe the project precisely in the deed: The more detailed your project (area, height, number of storeys), the more protection you will have. Avoid vague wording such as 'possible construction of a house'.
• Keep all exchanges with the seller: If the seller made oral or written promises about buildability, keep them. They may be used in the event of a dispute to prove the contractual guarantee.
• Consult a lawyer lawyer before signing: A professional can detect trap clauses and advise you on precautions to take. The cost of a consultation is negligible compared to the risk of losing your investment.

This 1977 decision is part of a consistent line of the Court of Cassation. One can cite a judgment of 3 March 1993 (No. 91-10.600) where the Court ruled that the seller of non-building land must compensate the buyer, even if the contract did not mention a specific project, as long as the seller knew that the buyer wanted to build. The trend is therefore protective for buyers.

However, since 1977, planning law has evolved. PLUs are stricter, and planning certificates (official documents indicating whether land is building land) have become common. Today, a diligent buyer requests a planning certificate before buying. Recent case law (for example, judgment of 26 May 2016, No. 15-16.426) specifies that the seller is not obliged to inform the buyer of planning rules if the buyer has the means to know them. But if the seller makes a specific promise, he remains liable.

What you absolutely must remember

FAQ:

1. Can I cancel the sale of a plot if planning permission is refused? Yes, if the contract provided for a specific project and the refusal is due to a characteristic of the land (non-building status, easement, etc.). You can request rescission and damages.

2. Is the seller always liable? No, if the contract does not specify a project, or if the refusal is due to your own imprudence (for example, a project not complying with rules you should have known).

3. What damages can I obtain? Repayment of the price, notary's fees, architect's fees, loan interest, and sometimes compensation for loss of chance.

4. Is there a time limit to act? Yes, the action for latent defects must be brought within two years of discovering the defect (Article 1648 of the Civil Code). The refusal of planning permission is the starting point.

5. What if the seller refuses to negotiate? Take the matter to the judicial court. Mediation can be attempted, but often litigation is unavoidable. A lawyer will help you assess your chances.
