(1) If such use is discontinued for six consecutive months, any future use of the building premises shall conform to this chapter.
(2) Uses or adjuncts thereof that are or become nuisances shall not be entitled to continue as non-conforming uses.
(B) If any non-conforming use or structure is destroyed by any means, including flood, it shall not be reconstructed if the cost is more than 50% of the market value of the structure before the damage occurred, unless it is reconstructed in conformity with the provisions of this chapter. This limitation does not include the cost of any alteration to comply with existing state or local health, sanitary, building or safety codes or regulations or the cost of any alteration of a structure listed on the National Register of Historic Places; provided that, the alteration shall not preclude its continued designation.
