Rebuilding. A nonconforming structure may be rebuilt in the event of its total or partial destruction, to occupy the same or a lesser amount of footprint, but may not exceed the original height of the totally or partially destroyed structure. Such rebuilding shall require site plan review and approval by the Planning Board.

Expansion. The Planning Board may issue a special use permit allowing an expansion of a nonconforming structure by up to 50% of its area in gross square feet at the time of the effective date of this chapter, provided that all other requirements for a special use permit can be met and that such expansion does not reduce any nonconforming setbacks by more than 20%. No use prohibited by § 108-4.3D may be expanded.

Repair. A nonconforming structure may be repaired or restored to a safe condition.
