Where a lawful structure exists on the effective date of this Zoning Code, or any amendment thereto, which could not be built under the provisions of this Zoning Code by reason 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 regulations:
(a) No structure may be enlarged or altered in a way which increases its nonconformity, i.e. existing residences on lots of a width less than that required herein may add a rear porch, provided that other requirements relative to yard space and land coverage are met.
(b) Should a structure be destroyed by any means to an extent of more than fifty percent of its reasonable market value, it shall not be reconstructed except in conformity with the regulations of this Zoning Code.
(c) Should such structure be moved for any reason, it shall thereafter conform to the regulations for the district in which it is located after it is moved.
