Upon completion of any building project, the property owner shall apply to the Construction Official in writing for a certificate of occupancy. If the building is one requiring site plan approval, the Construction Official shall then request the following officials and agencies to make an on-site inspection of the project to assure that all conditions of the site plan approval and the applicable ordinances and codes of the Borough have been complied with: Sewerage Authority, Borough Engineer, Plumbing Inspector, Police Chief, Fire Chief, Shade Tree Commission, Zoning Officer, State Building Officer (where applicable), and Site and Design Committee. The listed officials and agencies shall report their findings in writing within 30 days. If their reports are favorable and if the Construction Official finds that all the requirements of the Building Code have been met, he shall issue a certificate of occupancy within 10 days thereof. If the building project is one which does not require design and site plan approval, the Construction Official shall determine compliance with the applicable codes and ordinances without reference to other officials and agencies, and thereupon grant or deny the certificate within 10 days thereafter.
