Art. 45 Decree Concerning the Building Permit (DPC)

1 If it concerns a project of significant importance or if the legal situation is unclear, a preliminary building permit application may be submitted, with the agreement of the municipal authority, before the actual application. The preliminary application only addresses the integration of the structure into the surrounding land (location, exterior appearance) and the land's facilities.

2 The preliminary application is accompanied by two copies of the site plan in accordance with Articles 12 and 13, as well as preliminary project plans at a scale of 1:100 or 1:200 analogously applying Article 14. For the rest, the procedure follows the provisions applicable to ordinary applications.

3 The general building permit binds the authorities dealing with the subsequent application for the building permit, provided that the latter is submitted within six months from the issuance of the general permit. The new application is only published if it affects public interests more than the general application. If no publication is made, notification is given to the neighbors of the public filing of the execution project according to Article 21.
