What is a subdivision ?
It is the fact of dividing a plot into several lots to allow the construction of several individual houses. The owner must ensure that his plot is in a building zone and that the reorganization connections can be made in accordance with the regulations in force before the sale.
It will then be necessary to carry out an act of demarcation, then it is preferable and common to draft (or to have written) a specification and the regulation of the subdivision.
