Planning Permission or Subdivision Approval: The Court of Cassation Rules on a Property Dispute

Imagine: you own a plot of land in Arles, and you plan to build two houses on it for your children. Do you need planning permission or subdivision approval? The question seems technical, but the error could cost you thousands of euros. In 1985, the Court of Cassation ruled decisively: when the construction of several buildings involves a division of the land, you must obtain planning permission. There is no question of confusing the procedures.

But what exactly does this change? In this case, a buyer had promised to submit a planning application within one month of the promise to sell. He ultimately submitted an application for subdivision approval. Result: the seller kept the deposit, and the buyer lost his money. The Supreme Court upheld this penalty, considering that the buyer had not honoured his commitment.

This decision, although nearly 40 years old, remains relevant. It illustrates the rigour required in planning matters. undefined, I have come across cases where owners, due to a lack of clear distinction, found themselves blocked. So, how can you avoid this trap? Follow the guide.

The Facts: A Story That Happens Every Day

Mr X, an owner in Arles, signs a promise to sell a building plot. The buyer undertakes to submit, within one month, a planning application for a dwelling house or a group of dwellings. If the buyer does not respect this undertaking, the deposit (a sum paid to secure the sale) remains with the seller.

The buyer, instead of submitting a planning application, submits an application for subdivision approval. Why? Because the project involves the construction of several buildings on the land, and the land must be divided into several plots. The buyer thinks that the subdivision procedure is the correct one. But the seller considers that the undertaking has not been honoured and refuses to return the deposit.

The dispute goes to court, then to the Court of Appeal, and finally to the Court of Cassation. The lower courts rule in favour of the seller: the buyer should have submitted a planning application, not a subdivision approval. The buyer appeals to the Court of Cassation, arguing that his project fell under subdivision. But the Court of Cassation dismisses his appeal. It confirms that, under Article R. 421-7-1 of the French Urban Planning Code (now R*421-19), the construction of several buildings on the same plot, where the land must be divided, is subject to planning permission, not subdivision approval.

In other words, the buyer made a fatal procedural error. He lost his deposit. A lesson for any project developer.

The Reasoning of the Court — Analysed

The Court of Cassation relies on Article R. 421-7-1 of the French Urban Planning Code (in its version then in force). This provision states that "the construction on the same land, by a single person, of several buildings where the land is to be divided in ownership or use" is subject to planning permission. In short, when you build several buildings and divide the land to sell or lease them separately, planning permission takes precedence.

However, note: the text excludes cases where the buildings are intended to be leased or sold to different persons. In that case, subdivision approval is required. But here, the buyer had not specified that he would sell the plots. He had simply promised to submit a planning application for a house or a group of dwellings. Now, a group of dwellings implies a division, therefore planning permission. The Court validates the reasoning of the Court of Appeal: the buyer had undertaken to submit a planning application, and he submitted a subdivision approval. It does not matter that the latter may have been more appropriate: the contractual undertaking was clear.

What few people know is that the distinction between planning permission and subdivision approval is not always obvious. The Court of Cassation confirmed that, even if the project falls under subdivision, if the buyer undertook to submit a planning application, he must do so. Non-compliance with the undertaking leads to the loss of the deposit. This is a strict application of the principle of contractual obligation.

The judges did not rule on the actual nature of the project (planning permission or subdivision), but on compliance with the undertaking. The buyer could have submitted a planning application and then, if necessary, applied for subdivision approval later. But he chose the wrong box, and he pays the price.

What This Means for You — Practically

If you are the owner of a plot of land and you plan to build several buildings on it (for example, two houses in La Ciotat to rent out), know that the procedure to follow depends on the future use. If you divide the land into plots to sell or lease them separately, you will need planning permission for each building, and possibly subdivision approval if the division is prior. But if you keep sole ownership and lease the buildings to different tenants, planning permission generally suffices.

For buyers, the lesson is clear: strictly comply with the undertakings in the promise to sell. If you promise to submit a planning application, do not submit something else, even if you think it is more appropriate. You risk losing your deposit, which can amount to 5% to 10% of the sale price. On a plot worth €200,000, that is €10,000 to €20,000 lost.

If you are a seller, you can insist on strict compliance with the conditions. Case law protects you. In case of doubt, do not hesitate to specify in the promise the type of permission expected.

For real estate professionals (agents, notaries), this decision reminds of the importance of advising the parties properly. A qualification error can lead to costly disputes.

Four Tips to Avoid This Type of Dispute

• Clearly identify your project: before signing a promise, determine whether you are building one or several buildings, and whether the land will be divided. Consult an architect or a town planner to find out what permission is required.
• Draft the obligations precisely: in the promise to sell, specify the type of permission to be obtained (planning permission, development consent, etc.) and the deadline. Avoid vague terms like "planning authorisation".
• Strictly adhere to deadlines: a single day's delay can be enough to lose the deposit. If you are unsure, submit a preliminary application or request a written extension from the seller.
• Get assistance from a lawyer: a property law professional can verify the compliance of your project and save you from costly mistakes. A 30-minute consultation can save you months of litigation.

This 1985 decision is part of a consistent line of the Court of Cassation. For example, in a judgment of 12 July 1994 (no. 92-17.211), the Court held that the lack of planning permission for a construction requiring a division of the land renders the sale void. More recently, the Court confirmed that subdivision approval cannot replace planning permission when the buildings are constructed before the division (Civ. 3e, 19 May 2016, no. 14-29.783).

The trend is therefore towards rigour: judges verify the exact nature of the permission applied for and penalise any error. Since 1985, the Urban Planning Code has evolved, but the principle remains the same: when construction and division are linked, planning permission is required, subject to limited exceptions. In the future, it is likely that courts will continue to apply this rule strictly, especially in high-demand areas where abusive divisions are common.

Key Points to Remember

FAQ:

• What is the difference between planning permission and subdivision approval? Planning permission authorises the construction of a building. Subdivision approval authorises the division of land into plots intended for building. When both operations are concurrent, planning permission generally takes precedence.
• Can I apply for subdivision approval after obtaining planning permission? Yes, if the division occurs after construction. But be careful with the order of operations: if the division is prior, you must first obtain subdivision approval, then planning permission.
• What should I do if I have used the wrong procedure? If you have already submitted an incorrect application, withdraw it and submit the correct one. If you have signed a promise, renegotiate the terms with the seller to avoid losing the deposit.
• What are the risks if I make a mistake? Besides losing the deposit, you may be sued for non-performance of contract, or even face annulment of the sale. Penalties may apply.
• Can a notary advise me on this point? Yes, but a lawyer specialising in property law is often better equipped to handle disputes. For simple advice, a consultation with a lawyer is recommended.
