Reconstruction of Nonconforming Building or Structure. In the event that any nonconforming building or structure is destroyed or partially destroyed by fire, explosion or other cause, such nonconforming building structure may be reconstructed and the nonconforming use thereof continued if such reconstruction is commenced within six months of the date of the destruction or damage thereto and is pursued diligently to completion. Provided, however, that in such reconstruction the said building or structure destroyed or damaged shall not exceed the size of the nonconforming building or structure destroyed or damaged and, shall be placed in the same location on the ground as the nonconforming building or structure destroyed or damaged and, the nonconforming use thereof shall not differ from that existing prior to such damage or destruction unless a variance is applied for and obtained under this chapter, except that the repair, renovation or modernization of such nonconforming building or structure authorized by Subsection 1D of this Part shall nevertheless be permitted. Any such reconstruction shall be subject to and in accordance with existing Building [Chapter 5, Part 1, § 5-101], Electrical [Chapter 5, Part 1, § 5-105], Fire and Plumbing [Chapter 5, Part 1, § 5-102] Codes, safety regulations or laws. If reconstruction does not commence within six months after the occurrence of the damage or destruction, or is not thereafter diligently completed, then any further use, buildings or structures on the lot shall be in conformity with the provisions of this chapter.
