Where a lawful structure exists at the effective date of adoption or amendment of this zoning ordinance that could not be built under the terms of this zoning ordinance by reason of restrictions on area, lot coverage, height, yards, its location on the lot, bulk, 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 non-conforming structure may be enlarged or altered in a way which increases its non-conformity, but any structure or portion thereof may be altered to decrease its non-conformity;
(b) Should such non-conforming structure or non-conforming portion of structure be destroyed by fire or an Act of God, it may after approval by the Board of Zoning Appeals, be reconstructed as it previously existed. All remaining debris shall be cleared away and disposed of properly within two months of the time of destruction;
(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.
