What city planning authorization should be given to build a veranda?
Verified 11 April 2025 - Directorate for Legal and Administrative Information (Prime Minister)
To build a veranda, you must file a preliminary declaration of works (DP) or an application for a building permit (PC) in the town hall. The authorization to be deposited depends on the location of the land (in the urban area of a MORE: titleContent or not, in protected area or not) and the surface of your veranda. We're presenting the regulations.
In any case, you should consult the PLU of your municipality which may provide rules on building materials and the installation of the veranda in relation to neighboring properties. To find out about these rules, you must contact the city planning department of your city hall.
If the PLU does not provide for special rules, you must build your veranda either at the edge of your property or at least 3 meters from it.
In addition, if the veranda brings a view to your neighbor's house, you must also respect distance rules in relation to the limits of his property.
One DP or a PC is necessary depending on whether your veranda is located in an urban area of a MORE: titleContent or outside. You can get that information from your city hall.
