Where a lawful structure exists upon the effective date of the adoption or amendment of this Zoning Ordinance that could not be built under this Zoning Ordinance because of restrictions on area, lot coverage, height, yards or other characteristics of the structure or its location on the lot, such structure may be continued, so long as it remains otherwise lawful, subject to the following provisions:
(a) No such structure shall be enlarged or altered in a way that increases its nonconformity, but such structures may be enlarged or altered in a way that does not increase its nonconformity. An alternation or enlargement of a structure that would not increase the nonconformity could include adding a bay window or other architectural features (i.e. dormer), providing it does not increase the floor area of the use, and changing exterior facade treatments. Consideration of other such changes shall be within the purview of the Zoning Administrator in coordination with the Building Official. However, an unenclosed porch or portico may be added to a legally nonconforming structure of greater than fifty (50) years in accordance with the provisions of Section 4.05(d).
(b) Should such structure be destroyed, by any means, the same may be reconstructed within one (1) year from the date of destruction, without regard to conformity with this Zoning Ordinance, so long as the same type and style of structure are rebuilt in the same location and area of the destroyed structure.
(c) Should such structure be moved for any reason for any distance, it shall thereafter conform to the regulations of the district in which it is located after it is moved.
