Building Commitment: Lack of Planning Permission Does Not Constitute Force Majeure

You have just purchased a plot of land in La Seyne-sur-Mer, with the firm intention of building your house there. To lighten the bill, you signed a commitment in the acquisition deed to build dwellings within four years, which allowed you to benefit from a reduced rate on transfer duties. But here is the rub: the planning certificate you had before you specified that the land was in a rural zone, and you thought you could build without difficulty. Except that the planning permission is refused because the project does not comply with the planning rules. What happens? The tax authorities demand the additional duties, and you believe you are entitled to invoke force majeure. But the courts decide otherwise, as illustrated by a judgment of the Court of Cassation of 17 July 1974. An analysis of a decision that still resonates today in law firms and courts.

The question that every property owner who has entered into such a commitment asks: if I cannot build because the planning rules have changed or my project is not compliant, am I released from my obligation? The answer of the Court of Cassation is unequivocal: an error of judgment regarding the buildability of the land does not constitute a case of force majeure. In other words, the risk of non-buildability lies with the buyer, who must check before buying that his project is feasible.

This decision, handed down nearly fifty years ago, remains a reference for all property professionals and individuals. It reminds us that a building commitment is a serious act, whose tax consequences can be severe in case of non-compliance. So how can this trap be avoided? And what to do if you are already in this situation? Follow the guide.

The Facts: A Story Like Many Others

Mr X, a property owner in Toulon, buys in 1968 a plot of land located in a rural area in the municipality of La Seyne-sur-Mer. To benefit from the reduced rate of transfer duties provided for by former Article 1371 of the General Tax Code, he undertakes in the acquisition deed to build residential premises within four years. The planning certificate issued by the administration states that the land is in a rural zone, but that buildings may be authorised under certain conditions. Relying on this information, Mr X applies for planning permission for a single-family house project. But the municipality refuses the permit, considering that the project does not comply with the rules applicable to the zone, particularly regarding distance from public roads and minimum area.

Mr X therefore does not build within four years. The tax authorities then demand the additional transfer duties, amounting to several thousand euros (updated). Mr X challenges this, invoking force majeure: according to him, the impossibility of building resulted from the refusal of the permit, which he could not have foreseen. Did the administrative court rule in his favour? No. The judicial court (at the time the tribunal de grande instance) dismisses his claim, and the Court of Cassation confirms in 1974.

The judges' reasoning is relentless: the planning certificate clearly stated that buildings could be authorised subject to conditions. However, Mr X's project did not comply with these conditions. The impossibility of building therefore did not arise from an unforeseeable and irresistible event (force majeure), but from an error of judgment on the part of the buyer. In short, Mr X should have checked the conformity of his project before buying and entering into the commitment.

The Reasoning of the Court — Analysed

The Court of Cassation relies on former Article 1371 of the General Tax Code, which makes the benefit of the reduced rate subject to two cumulative conditions: on the one hand, the undertaking given in the acquisition deed to carry out the dwellings within four years; on the other hand, proof, within that same period, of the execution of the works, except in cases of force majeure. The question was therefore whether the refusal of planning permission constituted a case of force majeure.

For the Court, force majeure requires an event that is unforeseeable, irresistible, and external to the will of the person who made the commitment. However, the refusal of the permit was neither unforeseeable nor irresistible: the planning certificate specified the conditions to be complied with, and Mr X had the opportunity to check the conformity of his project before the purchase. By failing to do so, he took a risk, the consequences of which he must bear.

What few people know is that this decision is part of a consistent line of case law. The courts consider that the buyer of land is deemed to know the applicable planning rules, or at least must inform himself. The administration does not have to inform him of potential obstacles: it is up to him to exercise diligence. undefined, I have come across cases where property owners, trusting the word of the seller or an estate agent, proceed without checking the Local Urban Plan (PLU). Result: they end up with non-buildable land and a tax debt.

However, note that the Court of Cassation did not say that a refusal of planning permission can never constitute force majeure. For example, if the refusal is based on an unforeseeable modification of the PLU that occurred after the acquisition, the situation might be different. But in our case, the planning certificate was clear, and Mr X's project did not comply with the stated conditions. In other words, the impossibility of building was foreseeable from the outset.

What This Means for You — Practically

For a landlord in Toulon: if you buy land with a commitment to build dwellings, you must imperatively check the feasibility of your project before signing. A simple look at the PLU is not enough: you need to consult the planning department of the municipality, obtain an operational planning certificate (which indicates whether the land is buildable and under what conditions), and possibly submit a preliminary planning application. Example: for a plot of land worth €200,000, the reduced transfer duties may be €5,000 instead of €10,000. If you do not build, the administration will claim the difference, i.e. €5,000, plus late payment interest.

For a private buyer in La Seyne-sur-Mer: if you plan to build your main residence, the building commitment may seem advantageous. But beware: non-compliance with the commitment exposes you to a tax adjustment. Before signing, have a soil study carried out, check for easements (e.g. a right of way or an overhead power line), and ensure that your project complies with the subdivision regulations if any.

For a property professional: you must inform your clients of the risks associated with the building commitment. A developer who buys land with such a commitment and fails to obtain planning permission will lose the benefit of the reduced rate, which can eat into his margin. undefined, I have seen cases where the tax administration claimed several tens of thousands of euros from companies that underestimated planning constraints.

Four Tips to Avoid This Type of Dispute

• Check the PLU before any purchase. Go to the town hall or consult the municipality's website to find out the zoning and applicable rules. Do not rely solely on the seller's information.
• Obtain a pre-operational planning certificate. This official document tells you whether the land is buildable and what conditions must be met. It is valid for 18 months and protects you in case of changes in regulations.
• Do not sign a building commitment without having submitted a planning application. Ideally, obtain a final planning permission free of any appeals before the acquisition. Otherwise, include a condition precedent in the deed linked to the obtaining of the permit.
• Consult a solicitor specialising in property law. A professional can advise you on the drafting of the deed and the guarantees to be provided. The cost of a consultation is negligible compared to the financial stakes.

Further Analysis: Related Case Law and Developments

The decision of 17 July 1974 is not an isolated one. In a judgment of 13 March 1973 (No. 72-10.123), the Court of Cassation had already held that a refusal of planning permission based on the non-conformity of the project with the land use plan does not constitute force majeure. More recently, case law has clarified that even a change in regulations occurring after the acquisition may be considered foreseeable in certain cases (for example, if the land is located in a classified area).

The tendency of the courts is therefore to limit the notion of force majeure in this context. The judges consider that the buyer must exercise diligence and cannot hide behind ignorance of planning rules. This position has been consistent since the 1970s and has not been called into question by recent reforms in planning law.

For the future, it is likely that the courts will continue to apply this rule, except in very exceptional cases where the administration has committed an error (for example, by issuing an incorrect planning certificate). But note: in that case, it is not force majeure that applies, but the liability of the administration.

In Practice: What to Do

FAQ - Frequently Asked Questions

1. I bought land with a building commitment, but the PLU has changed since. Can I invoke force majeure? Possibly, if the change was unforeseeable. But you will have to prove that you could not reasonably have anticipated this change at the time of purchase. For example, if the PLU was modified after the acquisition to classify your land as non-buildable, this could constitute force majeure. But it is not automatic: the judges examine each case individually.
2. What should I do if the administration demands the additional duties? Do not pay without challenging it. You can file a claim with the tax office, then take the matter to the judicial court. But watch the deadlines: you have two years from the notification of the adjustment to take action.
3. Can I sell the land before the four years are up to avoid the adjustment? No, the commitment is personal and binds you until the expiry of the period. If you sell, you remain liable for the additional duties if the building is not carried out. However, the new owner can take over the commitment, but this requires an amendment to the deed.
4. What is the amount of the additional duties? Generally, the difference between the reduced rate (approx. 0.70% for building land) and the normal rate (approx. 5.80%), i.e. about 5.1% of the acquisition price. On a plot of €200,000, this amounts to €10,200, not including late payment interest.
5. Is it possible to negotiate an extension of time with the administration? Yes, you can request an extension for reasons of force majeure. But as we have seen, the conditions are strict. It is advisable to consult a solicitor to build a strong case.
