After all the studies we talked about earlier, the next step is to obtain the authorization to carry out the intervention works (a building permit). The procedure has several stages: a local planning certificate is requested from the local town hall, indicating what is permitted according to the local regulations and what other authorities must analyse in advance (mandatory bills) the project before issuing the permit. In the case of works on historic buildings (monuments) the views of the Directorate for County Culture and the State Inspectorate for Construction are mandatory.
The divisions responsible for culture evaluate (in theory) the way in which, through the project, the heritage value of the building is preserved and may request modifications of the solution so as to ensure a quality intervention in compliance with the principles of heritage protection. The culture divisions consult with the Regional Monuments Commission, composed of specialists in the field, for these approvals in order to issue relevant points of view. Unfortunately, in practice, more and more often, these opinions are conditioned by various interests, divergent from those of heritage conservation and enhancement. The project presented to the Directorate for Culture and implicitly to the Regional Commission contains the preliminary studies and the proposed architectural solution in which all the intervention works, repairs and possibly additions, modifications with the related justifications are made explicit.
