Garage placement rules on a plot

France · Auxiliary · usually permanent

A garage is a garden annexe: déclaration préalable from 5 to 20 m² and permis de construire above 20 m²; it may sit on the boundary or at least 3 m from it when the PLU sets no rule, with any extra constraints fixed by the local PLU.

Permit and notice

5–20 m² declaration; >20 m² building permit

Placement rules

A garage is usually treated as an outbuilding; the main planning issues are boundary setback and driveway access.

Boundary setback

Setbacks from plot boundaries and neighbouring buildings.

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.
