Greenhouse placement rules and setbacks
France · Auxiliary · usually lightweight
A greenhouse follows the same garden-annexe rules: no permit up to 5 m², déclaration préalable from 5 to 20 m², permis above 20 m², and placement on the boundary or at least 3 m away unless the PLU requires otherwise.
Permit and notice
≤5 m² none; 5–20 m² declaration; >20 m² building permit
Placement rules
A light garden structure for growing plants. The main planning issues are boundary setback, shade and water runoff.
Important limitation
The catalog is a planning aid, not a legal opinion. Before construction, check the land plot category, local land-use and development rules, easements, utility protection zones and neighbour buildings.
Sources
The editor will use the same source-backed passport for short in-canvas hints.
