A. 
Continuation. Any lawful building or structure or any lawful use of a building or structure or land existing on the effective date of this chapter or any amendment thereto which does not conform to the provisions of this chapter or any subsequent amendment shall be considered a lawful nonconforming building, structure or use and may be continued, except as otherwise provided herein.

(1) 
Any lawful nonconforming use of a portion of a building may be extended throughout the entire building area in existence upon the date of the subsequent amendment which rendered the use nonconforming.
(2) 
A lawful nonconforming use may be expanded no more than 25% of the area of an extension, expansion, or alteration of a building constructed after the effective date of this chapter or the date of the subsequent amendment which rendered the use nonconforming, and further provided that the expanded or altered building conforms with all height, setback, yard, and coverage requirements of the district in which the use is located.
(3) 
Nonconforming structures, including buildings, being used for a conforming use may continue in the current form of the structure and may be extended or altered if the extension or alteration does not increase the nonconformity of the building or structure with respect to the height, setback, yard or coverage requirements of the district in which it is located.
(4) 
The voluntary demolition, razing, or removal of a nonconforming structure or building, or portion thereof, shall be considered an abandonment of the nonconforming structure or building or the nonconforming portion of such building or structure. In such an instance, a nonconforming structure or building shall not be permitted to be replaced, reconstructed, or rebuilt with another nonconforming structure or building or otherwise maintain any preexisting nonconformity.
C. 
Restoration.[1] Any lawful nonconforming building or other structure which has been involuntarily damaged or destroyed by fire, explosion, windstorm or other similar active cause to an extent of not more than 75% of its fair market value may be reconstructed in the same location, provided that the reconstructed building or structure shall not exceed the height, area or volume of the damaged or destroyed building or structure, except as provided in Subsection B of this section hereinabove, and that reconstruction shall begin within one year from the date of damage or destruction and shall be carried on without interruption.
