What regulations apply to garden greenhouses in France?
In France, greenhouse regulations depend mainly on their ground surface area and height. The rules are established to ensure safety, urban planning, and respect for neighbors.
Small garden greenhouse (< 5 m²)
-
No declaration necessary: Small garden greenhouses under 5 m² and less than 1.80 m high do not require a prior declaration.
-
Practical advice: Even if a declaration is not mandatory, check your commune's Local Urban Plan (PLU).
Garden greenhouse (5 to 20 m²)
-
Prior declaration of works mandatory for these greenhouses, according to article R*421-9 of the Town Planning Code.

The form to be filled out is submitted to the town hall and allows information on the location and orientation of the greenhouse.
Practical advice: Take the opportunity to check the rules for positioning relative to neighbors and avoid conflicts.
Large garden greenhouse (> 20 m²)
-
Building permit mandatory, as for an extension or a garden building.
-
This permit ensures that the structure complies with urban planning and safety rules.
Practical advice: For large greenhouses, prepare a precise plan of the location, materials, and dimensions for the town hall application.
Greenhouse height and location
-
The maximum height for certain small greenhouses may be limited by the PLU.

The distance to property boundaries or neighbors must be respected to avoid any disputes.
