   A.    Alterations: A nonconforming building or structure shall not be reconstructed or altered to an extent exceeding twenty five percent (25%) of its market value for assessment purposes unless said building or structure is changed to conform with the regulations of this Chapter.

   B.    Enlargement: A nonconforming building or structure shall not be added to or enlarged in any manner unless such additions or enlargements are made so as to bring said building or structure into conformity with the regulations of this Chapter.
