Where a lawful structure exists at the effective date of adoption or amendment of this subchapter that could not be built under the terms of this chapter by reason of restrictions on area, lot coverage, height, yards, its location on the lot, or other requirements concerning the structure, such structure may be continued so long as it remains otherwise lawful, subject to the following provisions.
   (A)   No such nonconforming structure may be enlarged or altered in a way which increases its nonconformity, but any structure, or portion thereof, may be altered to decrease its nonconformity.
   (B)   Nothing in this chapter shall prevent the reconstruction of a building or structure, wholly or partly, destroyed by fire, flood, explosion, wind, and the like; provided such reconstruction is begun within six months and completed within two years.
   (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.
