(1) A nonconforming structure is destroyed or substantially destroyed or neglected by an intentional act of the owner or an agent without a proper permit. If this occurs, the nonconforming structure shall lose its nonconforming status and thereafter shall be required to be in conformity with existing codes. If a nonconforming use was in the destroyed or substantially destroyed structure, the nonconforming use and all site improvements shall lose their nonconforming status and be required thereafter to come into compliance with existing codes.

(2) A use, structure, or site improvement occurs to a nonconformity without being lawfully authorized in accordance with the provisions of this section. Such use and/or structure shall therefore cease all operations until such time that the required plans and/or permits are approved.
