Section 11.02   Nonconforming Buildings, Structures, and Uses
   (1)   No structural or physical alteration shall be made to any nonconforming building, structure, or lot unless otherwise allowed by these regulations. This requirement does not prohibit routine repairs or maintenance.
   (2)   No expansion shall be made of any nonconforming building, structure, or use unless such expansion conforms to the regulations specified for the district in which it is located. In cases where the nonconforming use occupies a building, structure, or any portion of a site, expanding the use into an additional building or land area shall constitute an extension and shall not be allowed.
   (3)   Any nonconforming building, structure, or use, or one (1) or more of a group of nonconforming buildings, structures, or uses related to one (1) industry and under one (1) ownership, which has been damaged by war, riot, fire, flood, explosion, earthquake, or other act of God may be reconstructed and used as before, if commenced within six (6) months of such calamity. The Town Council, after review and recommendation by the Planning and Zoning Commission, may determine that any delay in reconstruction beyond six (6) months was caused by unforeseen circumstances beyond the control of the owner of the premises and permit a reasonable extension of time for reconstruction. Any district requirements may be waived by the Town Council provided the area restored is not more nonconforming than existed at the time of the calamity.
   (4)   Any nonconforming building, structure, or use which ceases to be used for a period exceeding six (6) months or is superseded by a conforming use shall never again be devoted to the nonconforming use except as otherwise provided in the preceding paragraph. A nonconforming use shall not be changed to a different nonconforming use. This shall not prevent a name change or change in ownership of the same nonconforming use.
