§ 20.3-12  PRE-EXISTING CONDITIONAL USES.
   (A)   A conditional use legally established prior to the effective date of this zoning code or prior to the effective date of subsequent amendments to the regulations or zone boundaries, shall be permitted to continue; provided that, it is operated and maintained in accord with the conditions prescribed at the time of its establishment, if any.
   (B)   Alteration or expansion of a pre-existing conditional use shall be permitted only upon the granting of a use permit as prescribed in this section; provided that, alterations not exceeding in value 25% of the valuation of the existing use or building as determined by the town staff shall be permitted without the granting of a conditional use permit.
   (C)   A conditional use permit shall be required for the reconstruction of a structure housing a pre-existing conditional use if the structure is destroyed by fire or other calamity, by act of God or by the public enemy to a greater extent than 50%. The extent of damage or partial destruction shall be based upon the ration of the estimated cost of restoring the structure to its condition prior to such damage or partial destruction to the estimated cost of duplicating the entire structure as it existed prior thereto. Estimates for this purpose shall be made by or shall be reviewed and approved by the town staff and shall be based on the minimum cost of construction in compliance with the Building Code.
