The public domain consists of all "non-appropriable property": roads, sidewalks, squares, gardens, open or closed spaces for public use. As such, the private occupation of the public domain, on a temporary basis, is subject to prior authorization and must be the subject of a request to the services of the Collectivity. Violators of these rules are liable to a fine of the 5th class, described in article R 116 -2 of the Highway Code:
The penalties for fines of the fifth class will be fined:
1 ° Without authorization, have encroached on the public road domain or carried out an act which is likely to affect the integrity of this area or its dependencies, as well as that of works, installations, plantations established in the said domain ;
2 ° Have stolen materials stored on public roads and their dependencies for road purposes;
3 ° Without prior authorization and in a manner not conforming to the destination of the public road domain, have occupied all or part of this area or its dependencies or have made deposits there;
4 ° Have permitted or spilled or thrown on public roads substances likely to interfere with public health or safety or to inconvenience the public;
5 ° In the absence of authorization, trees or hedges shall be established or allowed to grow within two meters of the boundary of the public road domain;
6 ° Without prior authorization, have carried out work on the public road domain;
7 ° Without permission, have dug a subterranean under the public road domain.
For example, the amount of the fine for contraventions of the 5 class is 1500 € at most, which can be increased to 3000 € in the event of a repeat offense where the Regulation so provides.
