Failure to Obtain Planning Permission: Can a Neighbour Demand Demolition?

Imagine: in Saint-Cyprien, facing the sea, you see your neighbour erecting a building without the 'planning permission' sign being displayed. You wonder: is it legal? And above all, can you demand its demolition?

The question is legitimate. Every year, hundreds of owners, like in Argelès-sur-Mer, discover suspicious works and want to react. But beware: the law does not allow everything.

In a decision of 15 March 1977, the Court of Cassation ruled: a private individual cannot demand the demolition of a building solely on the ground of lack of planning permission. Why? Because planning permission is an administrative authorisation, which concerns the relationship between the builder and the administration. The neighbour, on the other hand, must prove that the lack of permission causes him personal and direct harm.

The Facts: A Story Like Many Others

In this case, owners of plots in a housing development had built a complex comprising a petrol station and its annexes. The initial planning permission had been granted, then revoked by the prefect. Despite this revocation, the owners continued the works.

Another developer, a neighbour, then sued the builders, seeking demolition of the building on the ground that the planning permission had been withdrawn. He argued that the building was illegal and should be removed.

The Court of Appeal of Lyon dismissed his claim, and the Court of Cassation upheld this decision. For the judges, the mere fact that planning permission is lacking does not suffice to justify demolition at the request of a private individual. Specific harm is required, such as loss of view, excessive shading, or a breach of planning rules affecting his rights.

The Reasoning of the Court — Analysed

The Court of Cassation relies on a fundamental principle of civil law: Article 1240 of the Civil Code (formerly 1382), which provides that 'any act of man, which causes damage to another, obliges the person by whose fault it occurred to repair it'. In other words, to obtain redress, one must prove fault, damage, and a causal link.

In this case, the lack of planning permission constitutes an administrative fault, but not necessarily a civil fault towards the neighbour. The judges consider that demolition is an extreme measure, which can only be ordered if the irregularity causes direct harm to the claimant.

This decision confirms settled case law: planning permission is a matter of administrative policing, and its violation primarily concerns the administrative court or the mayor. The private individual is not entitled to substitute for the administration. He can only act if his personal rights are impaired.

The claimant's arguments — the lack of permission — were deemed insufficient. The Court held that he had not demonstrated how this lack caused him specific harm. A lesson for all those tempted to challenge a building solely on planning grounds.

What This Means for You — Practically

If you own property in Argelès-sur-Mer and your neighbour builds without permission, know that you cannot demand demolition without proving harm. For example, if his construction blocks your sea view, you can act. But if it is merely unsightly or non-compliant with the local development plan, it is up to the town hall to react.

For the landlord: if you let a building and the tenant carries out works without permission, you can terminate the lease for fault, but not necessarily obtain demolition if the tenant moves out.

For the buyer: before purchasing a property, check for planning permission for recent works. If it is missing, you may have to regularise, but not demolish if no harm is caused.

A concrete example: in Saint-Cyprien, an owner built a 3-metre wall without permission. His neighbour lost 40% of his light. The court ordered demolition of the wall, as the harm was proved. Without such harm, the claim would have failed.

Four Tips to Avoid This Type of Dispute

• Consult the land registry and the local development plan before any property purchase. Identify recent constructions and ask the seller for planning permissions. If in doubt, a lawyer can verify compliance.
• If you are a victim of an illegal construction, document your harm. Take photos, measure the loss of sunlight, estimate the decrease in value of your property. The more concrete your harm, the better your chances of obtaining redress.
• Report the infringement to the town hall. The administration can order compliance or demolition, even without your action. It has policing powers that you do not.
• Consider mediation before going to court. Legal fees and expert costs can be high. A discussion with your neighbour, possibly through a justice conciliator, can resolve the conflict at lower cost.

Further Analysis: Related Case Law and Developments

This 1977 decision is part of a consistent line of authority. For example, in a decision of 12 July 1995 (No. 93-20.851), the Court of Cassation held that non-compliance with planning permission does not automatically justify demolition, unless the infringement of the neighbour's rights is established. Conversely, in a 2001 case, the Court ordered demolition of a building that blocked a neighbour's view, as the harm was obvious.

The trend is clear: judges are reluctant to order demolition for a mere procedural defect. They require material harm or an abnormal neighbourhood disturbance. Since the ALUR Act of 2014, criminal penalties for building without permission have increased, but the civil route remains conditional on personal harm.

For the future, it is expected that courts will continue to be pragmatic: demolition is a disproportionate measure if the building can be regularised or if there is no harm.

Checklist Before Acting

• Do I have personal harm? Loss of view, shading, noise nuisance? Without harm, no demolition possible.
• Do I have evidence? Photos, witness statements, bailiff's report, land registry extracts.
• Have I contacted the town hall? The administration can act more quickly and free of charge.
• What is the cost of legal action? Expect between €2,000 and €5,000 in legal fees, plus expert costs (€1,000 to €3,000). The procedure lasts on average 18 months at first instance.
• Can I obtain damages without demolition? Yes, if you prove a decrease in value of your property or disturbance of enjoyment. The court may award a lump sum.
