PROPERTY LAW — ENCROACHMENT
Rainwater from your neighbor’s roof pours onto your property every time it storms. Or the roof overhang extends 15 cm over your garden. In Nice, where houses are often built right up against each other on the hills of Cimiez or Fabron, these encroachments are common. But they’re not just a nuisance — they are violations of your property rights. Here’s how to deal with them in practice.
1. What counts as a roof encroachment
Several situations are possible:
- Roof overhang: the frame and tiles extend over your land. Even 5 cm counts as a clear encroachment.
- The gutter: it is fixed on your side or discharges rainwater onto your property. Article 681 of the French Civil Code requires rainwater to flow onto the land of the roof’s owner.
- The gable wall: the neighbor’s roof rests on your wall, or beams are embedded in your wall. This is an encroachment because your wall is your exclusive property.
2. Calculating the encroachment: why exact measurement is critical
An encroachment of just 3 cm can justify legal action. But it must be proven with centimeter-level precision. A tape measure isn’t sufficient for a legally sound report.
The professional method: a total station or 3D scanner measures the encroachment with an accuracy of 1 to 3 mm. Field experience regularly reveals roof overhangs of up to 8 cm using a Leica TS16. Without this measurement, the neighbor would dispute the claim — with it, the court ordered the demolition of the overhang under a penalty of €50 per day.
3. The step-by-step procedure
Step 1: Official record
Have the encroachment officially recorded by:
- A court bailiff (commissaire de justice) — cost around €200, their report is presumed accurate unless proven otherwise.
- Or a building expert — a detailed report with measurements, photos and plans. Cost: €800 to €1,500.
Step 2: Formal notice
Send a registered letter with acknowledgment of receipt, setting out the facts and demanding removal of the encroachment within 30 days.
Step 3: Legal action
If the neighbor refuses, file a claim with the Nice judicial court. An action to demolish the encroachment can be brought without having to prove any damage — the mere fact that the neighbor’s property encroaches on yours is enough. This is known as a possessory disturbance. Average time to obtain a judgment: 6 to 8 months.
The available legal remedies:
- Possessory action: a fast-track procedure (3 months) to stop the immediate disturbance.
- Petitory action: to have your ownership rights recognized and obtain permanent demolition.
4. Possible damages
Beyond demolition, you can also claim:
- Damages for loss of enjoyment (inability to use your land, nuisance, loss of sunlight)
- Repair of your wall if the gutter fixings have damaged it
- Expert and official record fees (€500 to €2,000 depending on the case)
Case study: Nice, Fabron district
A villa owner in Fabron found that the neighbor’s gutter was discharging all the rainwater from their 200 m² roof directly into their garden. The sloping terrain caused erosion and infiltration. After a formal notice went unanswered, an interim injunction order was obtained. The neighbor was ordered to: (1) remove the encroaching gutter within 45 days, (2) pay €1,800 in damages, (3) cover the €1,200 expert fees. Enforcement was carried out by a court bailiff.

Frequently asked questions
What can I do if my neighbor’s gutter overhangs my property in Nice?
You can request the removal or modification of the structure if the overhang is less than 0.50 m, as it is considered a right of way. If it exceeds this limit, it must be removed. Start by approaching your neighbor amicably, then, if they refuse, take legal action to assert your rights.
What is the legal distance for a gutter overhanging a neighboring property?
In France, a gutter may overhang a neighboring property provided the overhang does not exceed 0.50 m, unless a right of way or local regulation states otherwise. Beyond this measurement, the overhang is considered an encroachment and must be removed.
How do I precisely measure a gutter overhang onto a neighbor’s land?
Measure the horizontal distance between the vertical plane of the property boundary and the furthest point of the gutter. Use a spirit level or laser to ensure accuracy. This measurement is essential to determine whether the overhang is under 0.50 m and therefore permitted.
