If the authorised project is completed or marketed in stages, a certificate is drawn up for each stage, in proportion to each completion or marketing, within the limit of the period of validity of the commercial development authorisation as set out in article R. 752-20. The provisions of this article are set out in each certificate of conformity.
All certificates issued in this way are subject to the conditions of this sub-section and bear the endorsement of the authorisation to operate a business as well as the references of previously issued certificates.
