(a) The lawful use of any dwelling, building, or structure on any lot or premises existing and lawful at the time of the enactment of this Zoning Code, supplement, or amendment may continue although such use does not conform with the provisions of this Zoning Code or any supplement or amendment made after the enactment of this Zoning Code. A nonconforming use of a building may be changed to another nonconforming use of the same or more restricted classification.
(b) In the event that a nonconforming use of any dwelling, building, or structure and of any lot or premises is voluntarily discontinued for a continuous period of six (6) months, any future use of the lot, building, or structure shall be in conformity with the provisions of this Zoning Code.
(c) No nonconforming building or structure shall be moved in whole or in part to any other location on the lot, or to any other property, unless every portion of such building or structure is made to conform to all the regulations of the zone in which it is located.
(d) When a nonconforming building or structure has been damaged by explosion, fire, act of God, or the public enemy to the extent of more than 60% of its fair market value, it shall not be restored or reconstructed except in conformity with regulations of this Zoning Code.
(e) When a nonconforming use qualifies for reconstruction through damage (less than 60% of its fair market value), a building permit shall be secured for that purpose and reconstruction shall be diligently completed without delay. Failure to reconstruct within one (1) year of damage revokes the right to the nonconforming use and the premises shall conform thereafter to the established district regulations.
(f) A structure or building nonconforming as to use, height and yard requirements or lot area per dwelling unit shall not be added to or enlarged in any manner unless such structure or building, including such addition or enlargement, is made to conform to the use, height, yard and area requirements of this Zoning Code.
