Imagine you own a plot of land in Biscarrosse, near the lake. You dream of building a small luxury building with a view of the water, but you don't have the means to finance the project alone. A developer offers you a construction lease (a contract whereby you lease your land to them so they can build at their own expense, and you recover the property at the end of the lease). But here's the catch: the building permit hasn't been obtained yet. Can you sign the contract now, or must you wait? This is the question hundreds of property owners in the South-West of France ask themselves daily.
This situation is not theoretical. undefined in Mont-de-Marsan, I've seen real estate projects blocked for months because the parties hesitated to commit before obtaining the precious administrative authorisation. The developer wants to secure the land, the owner wants to guarantee the project, but no one knows if signing is legal without a permit. Until recently, the answer was unclear.
The Court of Cassation, in a decision of 20 October 2010, provided essential clarification. It ruled that Article L. 251-1 of the French Construction and Housing Code does not make the formation of a construction lease contract conditional on obtaining a building permit. In other words: yes, you can sign beforehand. But be careful: this freedom is not without practical consequences, and you need to understand exactly what this means for your project.
The Facts: A Story That Happens Every Day
Mr. Dubois, owner of a 2,000 m² plot in Dax, near the bullring, meets SCI (Société Civile Immobilière) Aquitaine Promotion. The latter wishes to build a complex of 12 homes with a shared swimming pool. The two parties negotiate a construction lease for a term of 50 years. In the draft contract, a clause provides that the lease will be concluded "subject to a suspensive condition (i.e., dependent on a future event) of obtaining the building permit". Mr. Dubois, being cautious, insists that this clause be included: he does not want to commit definitively if the permit is refused.
The SCI signs the contract, but Mr. Dubois refuses to initial the final document. Why? Because he believes that, even with this clause, the lease would already be formed (created) and he could be legally bound before obtaining the permit. He fears having to wait indefinitely, blocking his land, if the administrative procedure drags on. The SCI, for its part, claims that the clause is valid and that the contract will only exist once the permit is obtained. It accuses Mr. Dubois of causing the project to fail through his refusal.
The dispute goes to court. The Bordeaux Court of Appeal rules in favour of Mr. Dubois, considering that the clause does not truly suspend the formation of the contract. The SCI then files an appeal (a recourse) with the Court of Cassation. It is there that the judges of the highest French judicial court will decide. Their decision goes far beyond this simple disagreement: it establishes a general principle on the relationship between construction leases and building permits.
The Court's Reasoning — Analysed
The Court of Cassation examined Article L. 251-1 of the French Construction and Housing Code. This article defines the construction lease as a contract whereby the lessor (the landowner) gives a lessee (the builder) a building plot, in return for which the lessee undertakes to erect constructions at their own expense and maintain them in good condition during the lease term. At the expiry of the lease, the lessor recovers ownership of the constructions.
The text nowhere mentions that obtaining a building permit is a precondition for the formation of the contract. In short, the law does not require the permit to already be issued for the lease to be validly signed. The Court therefore ruled that the Court of Appeal had erred by distorting (incorrectly interpreting) the clear and precise terms of the suspensive clause. It quashed (annulled) the Court of Appeal's judgment.
This reasoning confirms prior case law (the body of court decisions). Already, in other cases, judges had considered that the parties were free to organise their contractual relations as they saw fit, provided they respected the law. Here, the suspensive clause is perfectly lawful: it allows the effects of the contract to be delayed until the condition is fulfilled (obtaining the permit). But what exactly does this change? It means that the lease does not exist legally until the permit is granted. If the permit is refused, the contract is considered never to have been formed, and the parties are released from their obligations.
The Court also analysed the arguments of both parties. The SCI argued that the clause was effective and protected Mr. Dubois. Mr. Dubois feared legal uncertainty. The judges ruled in favour of contractual freedom: if the parties want to include a suspensive condition, they can, and this clause must be respected. This is not a major evolution, but a confirmation of a well-established principle, often misunderstood by property owners.
What This Changes for You — Practically
If you are a lessor-owner, like Mr. Dubois in Dax, this decision gives you flexibility. You can sign a construction lease before obtaining the permit, by including a suspensive clause. This allows you to secure the project with a serious developer, without being definitively bound. For example, for land valued at €300,000 in the town centre of Mont-de-Marsan, you can sign a lease providing for a symbolic rent of €1 per year during the pre-permit phase, with a firm commitment from the developer once the permit is obtained. But be careful: you must check that the clause is well drafted to truly suspend the formation of the contract, not just certain effects.
If you are a lessee (developer or builder), this decision is good news. You can secure an interesting plot, like those near the lake in Biscarrosse, without waiting for administrative delays (often 3 to 6 months). This speeds up the implementation of your projects. However, you must be transparent with the owner about the risks: if the permit is refused, everything stops. undefined, I've encountered cases where developers underestimated this risk, leading to costly conflicts.
If you are a purchaser of a home in a construction lease project, this changes little for you directly, but it affects the project's security. Check that the permit is indeed obtained before signing your deed of sale. For a co-owner, if your building is constructed via a construction lease, ensure that deadlines are respected: construction must begin within a certain period after obtaining the permit, on pain of nullity (cancellation) of the lease.
Four Tips to Avoid This Type of Dispute
- Draft a clear and precise suspensive clause: In the contract, explicitly state that "the formation of this lease is suspended upon obtaining the definitive building permit". Avoid vague formulations like "subject to" which can cause confusion.
- Set a maximum deadline: Add that if the permit is not obtained within a reasonable period (e.g., 12 months), either party may terminate (end) the preliminary agreement. This avoids indefinite blockage.
- Consult a specialised lawyer before signing: A construction lease contract is complex. For a €500,000 project in Biscarrosse, investing €1,500 in legal consultation can save you disputes costing tens of thousands of euros.
- Document exchanges: Keep records of emails, letters, and meeting minutes with the other party. In case of conflict, this evidence will be crucial to demonstrate the real intentions.

Deep Dive: Related Case Law and Evolutions
Before this decision, other judgments had already addressed the issue. For example, a Court of Cassation judgment of 5 July 2006 (No. 04-10.302) had ruled that a suspensive condition linked to a building permit was valid in a sale contract. This 2010 decision extends this principle to construction leases, showing a trend of courts favouring contractual freedom.
What few people know is that this case law does not evolve quickly. Since 2010, several decisions have confirmed this approach, notably in cases concerning real estate projects in the Paris region. For the future, this means that property owners and developers can continue to use this mechanism, but they must remain vigilant about drafting clauses. Judges are attentive to ensuring that suspensive conditions truly suspend formation, and are not mere performance modalities.
Key Points to Remember

3. What risks if the clause is poorly drafted?
You could be legally bound even without a permit, with financial or deadline obligations.
4. How long does a typical construction lease last?
Between 18 and 99 years, often 50 to 70 years for real estate projects.
5. Does this decision apply to all types of construction?
Yes, whether for homes, commercial properties, or public facilities, as long as it's within the framework of a construction lease.
