The second paragraph of Article L. 145-18 reads as follows:
“The same applies to property restoration operations involving restoration, conservation, modernisation or demolition work resulting in the transformation of the habitable conditions of a group of buildings requiring the evacuation of the premises. These operations may be decided upon and carried out in accordance with local regulations, either by the local public authorities with jurisdiction, or at the initiative of one or more owners, whether or not grouped together in a building association. In the latter case, the owner(s) is (are) specially authorised to carry out the work under conditions laid down by the competent local authorities, which specify in particular the commitments required of the owner(s) with regard to the nature and extent of the work. Buildings acquired by a renovation body may, after restoration, only be sold by mutual agreement under the conditions of standard specifications approved by the said authorities. “
