Contact the city planning department of your city hall.

Rules may be laid down by:

- The local city planning plan (PLU)

- The communal map

- Local customs (unwritten rules)

2. If no local rules exist

You must respect a minimum height for your wall, including a chaperone (top of the roof-shaped wall).

Note: the law does not provide for a maximum height.

- Commune of less than 50,000 inhabitants: minimum height of 2.60 meters

- Municipality of 50,000 inhabitants or more: minimum height of 3.20 meters

There are other rules for the location of your future fence wall. They depend on the specifics of your land (land in subdivision, close to a road...).

You have to imperative contact the city planning department of your city hall to find out if there are any local rules to respect in relation to the neighboring land.

These rules may be laid down by the local city planning plan (PLU) or by the municipal map or by local customs.

Before building the wall, it is recommended to talk to your neighbor. If he accepts, you can then build the wall on the boundary separating your 2 plots by sharing the costs by half (this also avoids a loss of land). The wall will then be adjoining. If your neighbor refuses (for example, he or she does not want to contribute to the construction costs or see a wall on his or her land), you will need to build the wall only on your land. Otherwise, your neighbor may demand that the wall be demolished or moved.

Before you build the wall, you'll have to make a preliminary declaration of works to the city hall if you are in one of the following cases:

• The local city planning plan (PLU) requires it
• The height of the wall to be built is greater than or equal to 2 meters
• Your land is located in an area where it is mandatory. It can be the vicinity of a remarkable heritage site classified or a historic monument, a registered site (classified or awaiting classification), an area delimited by the PLU, an area defined by the municipality or theEPCI: titleContent.
