Do you want to enjoy your garden in complete privacy, but the current fence doesn’t hide anything? The temptation is great to hang a screen directly onto the existing mesh. Be careful, however: if this structure does not belong to you, you legally have no right to touch it without prior agreement. Between respect for property rights and technical constraints related to wind, here is what you need to know before you start to avoid any neighborhood conflict.
Key takeaways
- If the mesh fence is on the neighbor’s exclusive land, it is forbidden to attach anything to it. If the fence is shared (jointly owned), installation is possible but must not harm the solidity of the structure.
- Adding a privacy screen considerably increases wind resistance (sail effect). If the fence gives way under pressure, your civil liability will be engaged for the repairs.
- In the event of installation on a shared or neighboring fence, a simple oral agreement is not enough. Formalize the authorization in writing, specifying the material and the loads involved.
- To avoid any conflict, the best solution remains to “double” the fence (install your own posts on your land) or to plant a hedge while respecting legal distances.
Identifying the owner of the fence
The first step is to determine the legal status of the separation. If the mesh is installed entirely on your neighbor’s land (set back from the boundary line), it is their exclusive property. In this case, the law is strict: it is formally forbidden to attach anything to it, neither a privacy screen, nor reed screening, nor even a climbing plant, under penalty of being forced to remove everything at your expense and repair any damage.
If the fence is installed across the boundary of the two lots, it is presumed to be shared (jointly owned). You then have the right to use it, but with one major restriction: your installation must not compromise the solidity of the structure or cause abnormal disturbance to the other co-owner.
What is a shared fence?
A shared fence is a separation installed across the boundary of two lots, therefore presumed to belong to both neighbors. Each can enjoy it, but neither of the two can carry out an installation that would compromise the solidity of the structure. Conversely, a fence placed set back from the boundary, entirely on one plot, remains the exclusive property of its owner.
The technical danger: wind resistance
This is the point most often neglected by individuals. A flexible mesh or a standard rigid panel is designed to let air through. By attaching a privacy screen (woven fabric, PVC slats, heather), you transform this ventilated surface into a real “sail.” The wind resistance increases considerably, exerting enormous pressure on the posts and the concrete footings.
If you install a screen on the neighbor’s fence (even with their oral agreement) and the fence bends or is torn out during the next storm, your civil liability will be engaged. You will have to reimburse the full cost of the fence. This is why at Districlos, we always recommend checking the sizing of the posts before any installation of privacy screening.
Obtaining a written agreement to avoid disputes
If you maintain good relations with your neighbor, discussion is the best approach. It is possible that they also want more privacy. If they agree to you putting a privacy screen on their fence or on a shared fence, do not settle for a handshake.
Formalize this agreement in writing, specifying:
- The type of privacy screen installed (weight, material).
- The distribution of any costs.
- Recognition that the current structure is deemed fit to support the load.
The ideal solution: doubling the fence
To be completely free with your landscaping and avoid any legal risk, the safest method remains to install your own fence. This involves installing new posts and panels on your land, parallel to the neighbor’s mesh fence. You can place them a few centimeters from the boundary line (check your local urban planning regulations, or PLU, however).
This technique has two major advantages:
- You choose the aesthetics and the height (within the legal limit) of your screening.
- You install posts adapted to windy areas, guaranteeing the durability of your installation without depending on the existing one.
To prepare your own fence
- How deep should a fence post be set? : sizing foundations before installing screening in a windy area.
- Rigid mesh: how many posts to provide per panel? : calculating the number of posts for your second fence.
- How long does it take to install 100 m of rigid mesh fencing? : estimating the duration of the doubling project.
- Claustra or privacy screen: what is the difference and which should you choose? : comparing types of screening before purchase.
The alternative of a natural hedge
If installing a second rigid fence does not fit your budget or your tastes, planting remains an effective option. Planting a living hedge or shrubs allows you to create a natural visual screen without touching the neighbor’s fence.
Simply respect the planting distances imposed by the Civil Code (or local customs):
- Minimum 50 cm from the boundary line for plantings less than 2 meters high.
- Minimum 2 meters from the boundary for trees exceeding 2 meters in height.
Which option to choose according to your situation
| Solution | Authorization required | Risk in case of breakage | Freedom of choice (height, aesthetics) |
|---|---|---|---|
| Attachment to a fence located entirely at the neighbor’s | Forbidden, even with climbing plants or reed screening | Removal at your expense and repair of damage | None |
| Attachment to a shared fence | Written agreement from the co-owner of the structure | Civil liability engaged if the fence bends or is torn out | Limited: the installation must neither weaken the structure nor create abnormal disturbance |
| Doubling the fence with your own posts on your land | None, but check the local urban planning regulations (PLU) | At your expense, on your own structure | Total, within the legal height limit |
| Living hedge or shrubs | None, planting distances to be respected | No risk of wind resistance on the neighboring fence | Natural visual screen, progressive growth |
In short: if the mesh fence is installed entirely on the neighbor’s land, you are forbidden to attach a privacy screen, reed screening, or a climbing plant to it. If the fence is shared, installation is possible provided that the solidity of the structure is not compromised and a written agreement is obtained. The privacy screen creates a sail effect: in case of breakage, your civil liability is engaged. Doubling the fence on your land or planting a hedge remains the risk-free solution.
FAQ
Can I attach a privacy screen to a fence that belongs only to my neighbor?
No. If the mesh is installed entirely on the neighbor’s land, set back from the boundary line, it is their exclusive property. You cannot attach a privacy screen, reed screening, or climbing plant to it, under penalty of having to remove everything at your expense and repair any potential damage.
What if the fence is shared?
A fence placed across the boundary of two lots is presumed to be shared: it belongs to both neighbors. You have the right to use it, but your installation must not compromise the solidity of the structure or cause abnormal disturbance to the other co-owner.
What happens if the fence gives way because of the privacy screen?
The privacy screen transforms a ventilated surface into a sail and greatly increases the pressure exerted on the posts and footings. If the fence bends or is torn out during a storm, your civil liability is engaged and you must reimburse the full cost of the fence.
Is an oral agreement from my neighbor enough?
No, a handshake protects against nothing. Formalize the authorization in writing, specifying the type of privacy screen installed (weight, material), the distribution of costs, and the recognition that the existing structure is deemed fit to support the load.
At what distance from the boundary line can I plant a hedge?
The Civil Code, or local customs, requires a minimum of 50 cm from the boundary line for plantings less than 2 meters high, and a minimum of 2 meters for trees exceeding 2 meters in height.
Can I install my own fence in front of the neighbor’s?
Yes, this is the safest solution. You install your posts and panels on your land, parallel to the existing mesh, a few centimeters from the boundary line after checking your local urban planning regulations (PLU). You then choose the aesthetics, the height, and posts adapted to windy areas.
