A structure that is otherwise lawful and appropriate in the district in which it is located but which is nonconforming solely by reason of its failure to comply with restrictions on lot area, lot coverage, height, yards or other similar restrictions, may be continued so long as it remains otherwise lawful, subject to the following provisions.
   (a)   Expansion. Such structure may be enlarged or altered only in a manner that does not increase its nonconformity. Expansion is a change in the structure that extends a structure further into a required yard, further above the maximum height requirements or larger than the maximum cubical contents allowed by this chapter, or an increase in the mass of the structure in a required yard or above the maximum height allowed in this chapter.

   (b)   Repair or reconstruction. Should such structure be destroyed or damaged by any means to the extent of 51% or more of its replacement cost, exclusive of the foundation, it may be reconstructed only if it thereafter conforms with all the regulations of the district in which it is located and with applicable building codes.
   (c)   Relocation. Should such structure be moved any distance for any reason, it shall thereafter conform to the regulations of the district in which it is located after being moved.
