Thirty-Year Limitation Period for Project Managers: Beware of the Deadline to Act in Case of Defect

Imagine: you own a plot of land in Montdidier, in the Somme. You instruct an architect to obtain planning permission for two buildings. Contrary to all expectations, only part of the project is approved. You build one block of flats, but you lose the opportunity to build the second. Years later, you realise that you could have claimed damages. But what is the time limit for taking action? This is the question that the Court of Cassation settled in a judgment of 26 September 2007.

This decision is fundamental for all those who, in Péronne or elsewhere, engage a professional for a limited mission to obtain planning permission. Whether you are an owner, developer or even a tenant of a property that should have been larger, the limitation period is not what you think.

The High Court indeed held that when the damage does not result from a construction defect but from a loss of profit (inability to build as planned), the action is barred after thirty years, not ten years. A nuance that changes everything, especially when many professionals invoke the ten-year limitation period to escape liability.

The facts: a story that happens every day

Mr Y., an owner in Montdidier, entrusts a project manager with a very specific mission: obtaining planning permission for two buildings on his land. The professional submits the applications, but meets with refusals. Finally, planning permission for a single building is granted on 6 March 1980. Mr Y. builds the authorised building, but he is frustrated: the second building never saw the light of day.

Years later, believing that the project manager performed his mission poorly (by failing to obtain permission for both buildings), Mr Y. sues him to recover his loss of profit. The project manager, for his part, claims his fees for the refused applications.

The Amiens Court of Appeal is seised. The project manager raises the limitation defence: according to him, the liability action is subject to the ten-year limitation period for builders, which runs from the date of completion of the works. However, more than ten years have passed since construction. The case is therefore time-barred, he argues.

But Mr Y. retorts that his damage is not a construction defect, but a loss of chance to realise his original project. It is pure economic loss, unconnected with any construction defect. The applicable limitation period would therefore be the ordinary thirty-year period.

The Court of Cassation, seised of the matter, rules in favour of Mr Y. in its judgment of 26 September 2007. It confirms that the action, in the absence of any defect, targeted the damage resulting from a loss of profit. Consequently, the thirty-year limitation period applies. But attention: this period begins to run from the date of the causative event, i.e. at the latest on the day the disputed planning permission was granted, namely 6 March 1980. However, the action was brought more than 23 years later, which was within the thirty-year period. The action was therefore admissible.

The reasoning of the court — analysed

The crux of the reasoning lies in the characterisation of the damage. The Court of Cassation recalls that the ten-year limitation period (Article 1792 of the Civil Code) only applies to damage that compromises the solidity of the structure or renders it unfit for its purpose. Here, nothing of the sort: the building constructed is perfectly solid and habitable. The damage is purely economic: Mr Y. was unable to build the second building, and therefore lost the rents or the added value he could have derived from it.

The Court also uses Article 1240 of the Civil Code (the former Article 1382), which provides that "any act whatever of man which causes damage to another obliges him by whose fault it occurred to make reparation." To establish the liability of the project manager, it is necessary to prove a fault (here, failing to obtain permission for both buildings), damage (the loss of profit) and a causal link.

In doing so, the Court of Cassation excludes the application of the ten-year limitation period, which is shorter (ten years) and more favourable to builders. It applies the ordinary rules of civil liability, whose limitation period is thirty years (now reduced to five years since the 2008 reform, but for facts prior to that, the thirty-year period still applied).

This decision is a confirmation of previous case law: when the project manager's mission is limited to obtaining planning permission, and the damage does not result from a construction defect, the rules of ordinary contractual liability apply. No change in direction, but a welcome clarification.

The trial judges (Court of Appeal) had already adopted this reasoning, and the Court of Cassation approves them. The judgment therefore dismisses the project manager's appeal.

What this means for you — practically

Concretely, this decision has major implications for all property stakeholders.

For the landlord owner: if you entrust a professional with a mission to obtain planning permission for a project involving several buildings, and you only obtain partial permission, you have thirty years (now five years since 2008) to claim compensation for your loss of profit. Numerical example: in Péronne, an owner had planned to build two blocks of 6 flats each. The permission only authorises one. He builds the first, but loses the potential rents from the second (about €60,000 per year). He can claim this loss, provided he acts within the limitation period.

For the tenant: indirectly, if you rent a property that should have been larger (e.g., commercial premises with an extension), you could be concerned if the owner assigns you his right to sue. But most often, it is the owner who acts.

For the purchaser: if you buy land with planning permission obtained by a professional, and you later discover that the permission should have authorised more floor area, you can claim against the professional, within the limitation period.

For the co-owner: if the co-ownership suffers damage due to insufficient permission (e.g., reduced number of parking spaces), the managing agent can act.

What to remember: do not delay. Even if the period seems long (thirty years, or five years today), it runs from the causative event. Consult a lawyer as soon as you notice damage.

Four tips to avoid this type of dispute

• Have a precise mission contract drafted: the contract must clearly define the scope of the project manager's mission. If he is responsible for obtaining permission for a specific project, mention the number of buildings, floor areas, etc. This will avoid disputes over the extent of his obligation.
• Require regular progress reports: ask your architect or project manager to keep you informed of the progress of the permission applications. In case of refusal, you can react quickly, for example by modifying the project or changing professionals.
• Keep all documents: carefully keep correspondence, permission applications, refusals, the permission obtained, and the contract. These documents will be essential to prove fault and damage.
• Consult a lawyer at the first signs of difficulty: if you notice that the permission obtained does not match your project, do not wait. Prompt action can avoid limitation and maximise your chances of obtaining compensation.

Further reading: related case law and developments

This decision is part of a series of judgments by the Court of Cassation distinguishing between damage falling under the ten-year guarantee and that falling under ordinary law. For example, in a judgment of 28 November 2001 (No. 99-21.074), the Court held that damage resulting from a project manager's failure to advise (non-compliance with planning rules) was not a construction defect and fell under the thirty-year limitation period.

Another decision, of 12 July 2000 (No. 98-19.736), applied the same reasoning to an architect who had poorly advised his client on the feasibility of the project. The trend is therefore consistent: as soon as the damage is economic and unrelated to the solidity or purpose of the structure, the ordinary limitation period applies.

Since the reform of limitation by the Law of 17 June 2008, the ordinary period has been reduced from thirty to five years. For contracts concluded before 19 June 2008, the old thirty-year period may still apply. For contracts after that date, the five-year period runs from the date the damage becomes apparent.

This development makes the need for prompt action even more crucial: if you discover damage today, you have five years to act, not a day more.

Checklist before taking action

• Do I have a written contract with the professional? Yes → check the scope of his mission. No → gather evidence of his involvement (invoices, emails, etc.).
• What is my damage? Is it a loss of profit (lost rents, diminution in value) or a construction defect? This determines the applicable limitation period.
• When did the causative event occur? Usually, it is the date of the planning permission or refusal. Calculate the time elapsed.
• Do I have evidence? Gather all documents relating to the original project, the permission obtained, and communications with the professional.
• Should I act quickly? If you are within the time limit, consult a lawyer specialising in property law to bring an action.
