Any person obtaining a special exception or variance from the Zoning Hearing Board or by final, unappealable order of any court shall commence use or construction of the property for which such special exception or variance was obtained within one year following the date of the order of the Zoning Hearing Board or court; provided, however, that the Zoning Officer may issue extension beyond the one-year period if the Zoning Officer finds good cause therefor. If a landowner fails to comply with this timing requirement, the landowner shall not be permitted to use the premises or commence any construction or alterations in furtherance of such special exception or variance, and the Building Inspector may not issue a building permit in furtherance thereof, and it shall be necessary for the landowner to apply again to the Zoning Hearing Board for a special exception or variance the same as if no special exception or variance had been granted.
