After the date for the vacation of the structure, it is unlawful for any public utilities corporation or company to furnish gas or electrical service to any  structure which has been posted with notice by the inspecting official as unsafe or unfit, when the inspecting official in his discretion has notified the public utilities corporation or company in writing of his action in posting the structure as of the date and services shall be discontinued.  The utility service shall not be restored to a posted structure until notice in writing is received from the inspecting official authorizing the restoration of such service by the utilities corporation or company.  The inspecting official may authorize restoration of service to be used in connection with the revocation, repair or remodeling of the structure to comply with the provisions of this title. The inspecting official shall give such written authorization for the restoration of service when the posted notice is removed pursuant to the provisions of this chapter.  (Ord. 84/T-3098).
