   (a)   No such structure may be enlarged or altered in a way which increases the nonconformity.
   (b)   Should such structure be destroyed by any means to an extent of more than 50% of its replacement cost at time of destruction, it shall not be reconstructed except in conformity with the provisions of this Zoning Code.
   (c)   Should such structure be moved for any reason for any distance whatever, it shall thereafter conform to the regulations for the district in which it is located after it is moved.
