Non-compliant Planning Permission: Rescission of the Individual House Construction Contract

Imagine: you sign a contract to build the house of your dreams in Épernay. The builder tells you that planning permission has been granted. You rejoice, you plan your move. But a few weeks later, you discover that this permission does not correspond to the land: it is unsuitable, impossible to implement. The project falls through. What can you do? Are you bound by this contract?

This is precisely the question that the Court of Cassation decided in its judgment of 11 December 1991. It held that, when the planning permission obtained turns out to be non-compliant with the land, this situation is equivalent to a refusal of permission. Consequently, the individual house construction contract (CCMI) can be rescinded automatically, without the purchaser having to suffer the consequences of a hidden defect in obtaining the permission.

This decision, handed down over thirty years ago, remains a reference for all property owners and real estate professionals. It reminds us that the condition precedent of obtaining planning permission is not a mere formality: it must be genuine and achievable. Let us look together at the facts, the judges' reasoning, and what this means for you in practice.

The facts: a story that happens every day

Mr X, owner of a plot of land in Vitry-le-François, signs an individual house construction contract in 1984 with the company l'Immobilière de Construire. The contract is subject to a condition precedent (a clause that suspends the effects of the contract until the occurrence of an event): obtaining planning permission in accordance with the project. On 30 August 1984, the town hall grants the permission. Everything seems in order.

But very quickly, Mr X discovers that the permission granted does not correspond to the land: the construction project, as described in the permission, is impossible to carry out on the plot in question. In reality, the permission was granted for a different plot or with incompatible characteristics. Mr X informs the builder, who maintains that the permission is valid and demands performance of the contract.

The dispute begins: Mr X refuses to pay and requests rescission of the contract (its retroactive annulment). The builder sues him for payment. The Reims High Court, and then the Court of Appeal, rule in favour of Mr X: the contract is automatically rescinded, because obtaining non-compliant permission is equivalent to a refusal of permission. The builder appeals to the Court of Cassation, but the Court dismisses his appeal in 1991.

The court's reasoning — dissected

The Court of Cassation had to determine whether planning permission granted but non-compliant with the land could be considered a refusal of permission for the purposes of the condition precedent. The builder argued that permission had indeed been granted, so the condition was fulfilled and the contract had to be performed.

The judges adopted a pragmatic approach: they considered that the very purpose of the permission is to allow the construction project to be carried out. If the permission, because of its non-compliance, makes the project impossible, it is as if it had never been granted. Article 1178 of the Civil Code (relating to conditions precedent) provides that the condition is deemed fulfilled when its fulfilment has been prevented by the debtor. Here, that is not the case, but the situation is treated analogously: the non-fulfilment of the condition (obtaining compliant permission) leads to the lapse of the contract.

The Court of Appeal had already noted that "the planning permission granted having proved to be non-compliant with the land for which it was sought, the construction project, the object of this permission, could consequently not be carried out and this situation was equivalent to a refusal of planning permission". The Court of Cassation validates this reasoning: it is a legal justification for automatic rescission. In other words, the judges considered that the parties' intention was to build a compliant house, not to obtain any permission whatsoever.

This decision does not create a departure from precedent, but it confirms an interpretation protective of the purchaser. It is part of a consistent body of case law that ensures that conditions precedent are not diverted from their purpose.

What this means for you — in practice

If you are a private individual having a house built, this decision protects you: if the builder presents you with planning permission that, in reality, does not allow the planned project to be carried out (for example, because it imposes impossible technical constraints on your land), you can request rescission of the contract and recover any sums already paid. In Épernay, a client was thus able to obtain the annulment of his contract after discovering that the permission authorised a habitable floor area 20 m² less than planned.

For real estate professionals (builders, developers), this case law imposes an enhanced verification obligation: before filing a planning application, you must ensure its feasibility on the land. An error of assessment can lead to the loss of the contract and damages. In practice, if you are a builder and you have delivered non-compliant permission, you risk having to refund the deposit (often 5 to 10% of the contract price, i.e. several thousand euros) and pay damages for the loss suffered.

If you are a purchaser and you find yourself in this situation, you must act quickly: automatic rescission is not automatic; it must be declared by a judge. Keep all documents (permission, correspondence, plans) and send a formal notice to the builder. If no amicable agreement is reached, apply to the judicial court within 5 years of discovering the problem.

Four tips to avoid this type of dispute

• Check the compliance of the planning permission with your land before signing any contract. Use a surveyor or an architect to compare the authorised project with the characteristics of your plot (area, easements, planning rules). A quick glance is not enough.
• Insert a precise condition precedent clause in your construction contract. State that the permission must be "in conformity with the project and achievable on the land". Avoid vague wording such as "obtaining planning permission".
• Keep a copy of the permission and all correspondence with the builder. In the event of a dispute, these documents are your best evidence. Do not hesitate to photograph the land and the plans.
• If in doubt, consult a specialist lawyer before paying any deposit. A 30-minute consultation can save you years of litigation. In Vitry-le-François, clients have thus avoided signing a dangerous contract.

This 1991 decision has been confirmed and clarified by subsequent judgments. For example, the Court of Cassation held in 2005 (Civ. III, 9 March 2005, No. 03-19.123) that the refusal of planning permission notified after the signing of the contract causes the lapse of the condition precedent, even if the builder had already started work. Similarly, in 2012 (Civ. III, 10 July 2012, No. 11-20.678), it specified that the non-compliance of the permission must be assessed objectively, without regard to the builder's intention.

The trend of the courts is therefore clear: they protect the good faith purchaser. However, beware: if the purchaser was aware of the non-compliance at the time of signing, he could be considered complicit and lose his right to rescission. Recent case law (Court of Cassation, 2018) has also extended this protection to cases where the permission is subsequently annulled by the administrative court.

For the future, with the increasing complexity of planning rules (ALUR law, PLU), this type of dispute is likely to increase. It is therefore crucial to thoroughly document the feasibility of the project before any commitment.

Summary and next steps

FAQ:

• Can I terminate my contract if the planning permission is non-compliant? Yes, you can apply for automatic rescission before the court. The judge will declare that the condition precedent has not been fulfilled.
• What are the time limits for taking action? You have 5 years from the discovery of the problem. In practice, act within 6 months to avoid complications.
• Can the builder claim penalties from me? No, if rescission is granted, the contract is retroactively annulled. Each party must return what they have received. The builder cannot demand penalties.
• What if the builder refuses to acknowledge the non-compliance? Send a formal notice by registered letter with acknowledgement of receipt. If no response within 15 days, apply to the judicial court.
• Do I have to pay the lawyer before winning the case? Generally yes, but you can ask the judge to order the builder to pay your legal costs (Article 700 of the Code of Civil Procedure).
