You wish to fence your land and maximize your available space by installing your gate directly on the property boundary? This is a logical approach to secure access to your home without losing valuable square meters. In theory, every property owner has the right to enclose their land. However, installing a gate along a public road or at the boundary with a neighboring property is subject to strict regulations. Between the Civil Code, the Local Urban Development Plan (PLU), and respecting your neighbors, here is what you need to know to avoid having to dismantle everything.
The right to enclose and its legal limitations
According to Article 647 of the Civil Code, you have the absolute right to fence your property, which includes installing a gate. You can therefore technically position your structure on the extreme boundary of your land. However, this right ends where another person’s property or public space begins.
It is essential to know the exact location of the boundary line. If you are uncertain of the demarcation, only a boundary survey conducted by a licensed surveyor can officially define the limits of your parcel. Installing a gate, even by a few centimeters, on a neighbor’s land or on the sidewalk is illegal and may result in an immediate demolition order.
Consult the Local Urban Development Plan at the town hall
Before digging foundations or setting your posts, the first practical step is to consult the Local Urban Development Plan (PLU) of your municipality. This document sets out the specific regulations for your residential zone and may impose stricter constraints than the Civil Code.
The PLU may notably require:
- A mandatory setback from the public road (alignment) to ensure visibility or allow a vehicle to park in front of the entrance without obstructing traffic.
- A maximum height not to be exceeded for the gate and pillars.
- Aesthetic restrictions (colors, materials) if you are in a classified zone or near a historic monument.
The prohibition against encroaching on public space
This is the golden rule for an installation along a street: your gate must never, when opening, extend onto public property. This means that a swing gate cannot open outward (onto the sidewalk or roadway). This is a safety matter for pedestrians and motorists.
If you install your gate strictly on the property boundary, you must necessarily opt for inward opening into your courtyard. If your land slopes upward or lacks depth for the swing clearance of the leaves, installation on the boundary will become technically complex with a standard swing model.
The sliding gate solution for limited spaces
When one wishes to install a closure on the property boundary, it is often to save space. In this configuration, the sliding gate is the most suitable technical solution offered by Districlos. Unlike the swing gate, it requires no setback for opening since it slides laterally along the fence.
This mechanism allows the installation to be positioned right on the boundary line without concern for the opening radius, while complying with the prohibition against encroaching on the street. It is the ideal option for roadside entrances or short driveways where every centimeter counts for parking a vehicle.
Precautions in case of shared ownership
If your future gate must be attached to an existing wall or pillar that also belongs to your neighbor (shared wall), you cannot act alone. The installation must not compromise the structural integrity of the common structure.
It is mandatory to obtain written consent from your neighbor before drilling or anchoring hinges on a shared fence. If the gate is installed on your own pillars, built strictly on your land but positioned against the neighbor’s boundary, ensure that no element (pillar cap, motorization, stop) extends onto their property.
Must the work be declared?
Installing or replacing a gate modifies the external appearance of your dwelling. As such, a prior declaration of works (DP) is generally required at the town hall. It is during the review of this application that the planning services will verify whether your project complies with the setback and alignment regulations mentioned above. Do not neglect this administrative step: in case of non-compliance, the fine can be substantial and forced compliance may be required.
