Where, on the effective date of adoption or amendment of this Chapter, a lawful structure exists that could not be built under the regulations and standards of this Chapter as adopted or amended by reasons of restrictions on lot area, lot coverage, floor area ratio, heights, yards, spacing between buildings or other characteristics of the structure or its location on the lot, such structure may be continued so long as it remains lawful subject to the following provisions:
1.
No such structure may be enlarged or altered in a way which increases its non-conformity. On a non-conforming structure work may be done in any period of twelve (12) consecutive months on ordinary repairs or on repair or replacement of non-bearing walls, fixtures, wiring or plumbing, provided that the volume of such building or the size of such structure as it existed at the effective date of adoption or amendment of this Chapter shall not be increased.
2.
Should such structure be destroyed by any means to an extent of more than sixty percent (60%) of its replacement cost at the time of destruction, it shall not be reconstructed except in conformity with the provisions of this Chapter.
3.
Should any structure be moved for any reason for any distance whatever, it shall thereafter conform to the regulations and standards for the district in which it is located after it is moved.
