For a garden shed of less than 5 m², you will generally not have to do anything. The Local Urban Plan (PLU) sometimes provides for specific provisions linked to the residential area.
Any new installation in the garden may require prior authorization and result in a change in taxation. It is important to choose the location of the garden shed carefully so that it is sufficiently protected, while remaining practical. The garden cabinet, like larger sheds, is made of different materials, each with its advantages and disadvantages.
