Servitude of View in Paris: Why Your Neighbour Does Not Have to Endure Your Windows

Imagine you own a beautiful villa in Cannes, with a sunny terrace overlooking your garden. Your neighbour decides to construct a new building and installs windows that look directly into your property. You think they do not have the right, that it violates your privacy. But what is the reality? Does the law automatically protect you against these intrusive views?

This question is asked by thousands of owners each year on the French Riviera, whether in Cannes, Mougins, or Grasse. New constructions are multiplying, land is becoming denser, and with them, neighbourhood conflicts. Must one endure the neighbour's windows simply because they exist? The answer is not as simple as one might think.

A decision by the Court of Cassation (the highest French judicial court) dating from 1975 provides crucial clarification on this issue. It specifically concerns Paris, but its principles resonate far beyond. This decision recalls a fundamental rule: not all constraints between properties are servitudes (real rights that burden one property for the benefit of another). And sometimes, what you take for a violation of your rights is not one.

The Facts: A Story as Common as Any

Let us go back to 1975. In Paris, in the 16th arrondissement, two owners face each other. On one side, Mr. Dupont, owner of an old building constructed at the beginning of the century. On the other, the Société Immobilière du Parc, which acquires an adjacent plot and decides to construct a new building with luxury apartments.

During the works, the Société Immobilière du Parc installs several windows on the façade overlooking Mr. Dupont's courtyard. These windows, according to the decree of 13 August 1902 (a regulatory text specific to Paris), must respect minimum distances for direct views (openings that allow direct sight into the neighbour's property). But here is the issue: Mr. Dupont believes that these windows, even if compliant with the decree, violate his rights. He invokes a continuous and apparent servitude of view (a right acquired by prescription after 30 years of peaceful existence) that he claims to have held since 1932.

The conflict escalates. Mr. Dupont sues the Société Immobilière du Parc, seeking an order to block up the windows and payment of damages. At first instance, the court partially rules in favour of Mr. Dupont. The company appeals. The court of appeal reverses the decision: it considers that Mr. Dupont has not proven the existence of this servitude and that the 1902 decree does not create rights in favour of neighbours.

Mr. Dupont, obstinate, appeals to the Court of Cassation. He argues that servitudes of view can be established not only by title (written deed) but also by prescription, and that the court of appeal misappreciated his evidence. It is at this stage that the Court of Cassation intervenes, with a decision that will clarify the regime of views in Paris for the long term.

The Court's Reasoning — Analysed

The Court of Cassation, in its judgment of 4 February 1975, dismisses Mr. Dupont's appeal. Its reasoning rests on two essential pillars, which I will explain in clear language.

First pillar: the nature of the decree of 13 August 1902. The judges recall that this text, applicable only to the city of Paris, serves a purpose of public health (improving hygiene and living conditions). It imposes construction rules to guarantee light and ventilation in Parisian buildings, often dense and dark. But — and this is crucial — this decree does not have the effect of imposing reciprocal burdens on adjacent plots. In other words, it does not automatically create rights and obligations between neighbouring owners.

Second pillar: the distinction between regulation and servitude. Article 10 of this decree certainly sets rules for direct views from habitable rooms onto courtyards. But this provision does not confer any right and does not create any obligation for the neighbouring owner. Why? Because a servitude (such as a servitude of view) requires a title (a notarial deed, for example) or thirty-year prescription (30 years of peaceful use). A mere planning regulation does not create one.

In clear terms, the Court of Cassation says this: if your neighbour constructs in compliance with the 1902 decree, you cannot oppose a servitude simply because their windows bother you. You would need to prove that you already had an acquired right before their construction. In Mr. Dupont's case, the court of appeal had considered that he had not provided this proof — and the Court of Cassation validates this analysis.

This reasoning confirms prior case law. It recalls that property law is strict: one can only impose on others what the law or an agreement explicitly provides. A planning regulation, even if binding on the builder, does not transform neighbours into creditors of new rights.

What This Changes for You — Practically

But what does this change exactly for you, an owner in Cannes, Mougins, or elsewhere? A lot, in reality. This decision has practical implications depending on your situation.

If you are a landlord (who lets your property) and your neighbour constructs: you cannot oppose their windows simply because they overlook your property. Unless you hold a written or prescribed servitude, you will have to tolerate these views. undefined in Grasse, I have seen tenants complain about loss of privacy — but without a servitude, the landlord cannot demand anything from the neighbour. This can affect rental value: a terrace exposed in this way may see its value decrease by 10 to 20%.

If you are purchasing an old property: systematically check for the existence of servitudes in the sale deed or technical survey. In Mougins, for example, a villa from the 1950s may have acquired servitudes over the neighbouring plot. If that plot is buildable, the future neighbour will have to respect them — otherwise, you can take action. Without a servitude, as the decision reminds, you will have no recourse against new constructions.

If you are a co-owner: the rules are similar. The co-ownership regulations may provide additional restrictions, but they only bind the co-owners, not external neighbours. A new building constructed next door will have to respect the Local Urban Plan (PLU), but not necessarily your wishes.

However, be careful: this decision concerns Paris and its 1902 decree. On the French Riviera, it is the PLU of each commune that applies. In Cannes, for example, the PLU imposes distances for openings, but the principle remains the same: these rules do not create automatic servitudes. One must distinguish between infringement of the PLU (which the town hall can sanction) and private law between neighbours.

Four Tips to Avoid This Type of Dispute

How to react to prevent these costly and stressful conflicts? Here are four practical tips, drawn from my experience of over 15 years in real estate law.

• Before purchasing, have existing servitudes verified: instruct a notary or solicitor to examine the property's history. A servitude not mentioned in the deed may exist by prescription — but it must be proven. Cost: expect €500 to €1,000 for an in-depth study.
• If you are constructing, obtain an operational planning certificate: this document, issued by the town hall, indicates the rules applicable to your plot. In Grasse, this takes 1 to 2 months. It does not guarantee the absence of conflict, but reduces risks.
• Document any agreement with your neighbours in writing: if you accept views in exchange for consideration (for example, a contribution to fence costs), make a notarial deed. A simple email exchange is not sufficient to create a servitude.
• Monitor prescription periods: a continuous and apparent servitude is acquired after 30 years of peaceful use. If your neighbour installs an illicit window, act within 30 years, under penalty of it becoming an acquired right. In the Alpes-Maritimes, the courts are strict on this point.

Deep Dive: Related Case Law and Developments

The 1975 decision fits into a consistent line of case law. Already in 1956, the Court of Cassation had ruled that planning rules do not create servitudes (judgment of 7 March 1956). In 2008, it confirmed this principle for the PLU (judgment of 9 July 2008).

What few people know is that this case law also protects older owners. Imagine: you have had a house in Mougins for 40 years, with an unobstructed view. A developer buys the neighbouring plot and wants to construct a building that blocks your view. Without a servitude, you cannot prevent this — but they also cannot impose retroactive constraints on you. It is a delicate balance.

The trend in the courts, particularly in the Grasse jurisdiction, is toward strict evidential requirements. To establish a servitude, solid proof is needed: old plans, witness statements, notarial deeds. Mere assertions are insufficient. This means that, in the future, conflicts may become more complex with the digitisation of archives.

Summary and Next Steps

To summarise, here is what to remember in FAQ form:

• My neighbour installs windows that look into my property, what should I do? First check if they comply with the PLU. If they are in breach, alert the town hall. If they are compliant, check if you have a servitude. If not, you will have to tolerate it.
• What exactly is a servitude? It is a real right (that follows the property) that burdens one plot for the benefit of another. Example: right of way, right of view, right of water drainage.
• How to prove a servitude? By title (notarial deed) or by prescription (30 years of peaceful, continuous, and apparent use).
• Does the PLU create servitudes? No. The PLU is a planning regulation. It binds constructors, but does not create rights between neighbours.
• What are the time limits for taking action? To challenge a construction, generally 5 years from the end of works. To prescribe a servitude, 30 years.
