When purchasing a property (apartment, garage, commercial premises etc.) it is always necessary to check that it is in order from the point of view of the building ordinances, i.e. the existence of a building permit for its construction or “concessions” for any work subsequently carried out (it is often the case that work done without authorization was subsequently the subject of an amnesty by way of a corrective building concession).
For vacant land, it is always important to check its status (whether it is agricultural, whether building is permitted or whether there are scenic, archaeological or other types of restrictions) by way of a Town-Planning Certificate and to check that any subdivision was legally approved.
For all kinds of property, it is necessary to check that land registry records are in order.
For buildings, it is fundamental to ascertain that usage complies with the planning permit and the land registry specifications.
