There is no legal definition of the concept of commencement of work.. The judges assimilate the beginning of the work to the actual beginning of the work, that is, from the installation of fences around the place of work or the arrival of the material.

You can declare the beginning of your work directly online or on a form to send (or to deposit) to your town hall, preferably by registered letter with notice of reception.
