Use and occupancy certificates shall be granted or refused within ten days after date of application; and in case of refusal, the applicant shall be informed of his right of appeal to the Zoning Hearing Board. Before the Building Inspector issues such use and occupancy certificate, he shall make or cause to be made such investigation as he may deem necessary to ascertain whether the requirements of the original building permit, accompanying plans, specifications and documents and other requirements of this Zoning Ordinance and other applicable ordinances or regulations of the Borough have been fully complied with. In the event that such application is refused, the Building Inspector shall submit, in writing, a statement of the reasons upon which such refusal is based.
