Restoration of nonconforming uses or structures.
When a nonconforming building or use which does not conform to the provisions of this chapter, is damaged for any reason, including fire, explosion, act of God or the public enemy, to the extent of fifty percent (50%) or more of its appraised value as shown on the most recent tax roll of the town, or fifty percent (50%) or more of the physical structure, whichever is most restrictive, it shall not be restored except in conformity with the regulations of the district in which it is located. When damaged by less than fifty percent (50%) of appraised value or fifty percent (50%) of the physical structure, whichever is most restrictive, a nonconforming building may be repaired or reconstructed and used as before the time of damage, provided a building permit or demolition permit has been purchased within one hundred eighty (180) days of the time such building becomes damaged, but the existing square footage or function of the nonconforming use cannot be expanded, and the above procedures in subsection (e)(4) above shall be met.
