What city planning authorization to deposit to settle a garden shelter?
Verified 21 March 2025 - Directorate for Legal and Administrative Information (Prime Minister)
To settle a garden shelter, you must file a prior declaration of works (DP) or an application for a building permit (PC). 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), the layout of the garden shed (independent or not) and its surface. We're presenting the regulations.
In any case, you should consult the PLU of your municipality which can provide rules on building materials and the installation of the shelter compared 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 distances, you must build your garden shelter either at the edge of your property or at least 3 meters from it.
One DP or a PC is necessary depending on whether your garden shed is independent or not:
