165A.26   NONCONFORMING STRUCTURES.
   1.   Authority to Continue. Any structure that is devoted to a use that is permitted in the zoning district in which it is located, but which is located on a lot that does not comply with the applicable lot size requirements and/or the applicable bulk regulations, may be continued, so long as it remains otherwise lawful, subject to the restrictions of this section.
   2.   Enlargement, Repair, Alterations. Any such structure described in Subsection 1 may be enlarged, maintained, repaired or remodeled, provided, however, that no such enlargement, maintenance, repair or remodeling shall either create any additional nonconformity or increase the degree of existing nonconformity of all or any part of such structure, except that as to structures located on a lot that does not comply with the applicable lot size requirements, the side yard requirements shall be in conformance with this section, and unless otherwise permitted by conditional use permit unless otherwise approved or as specified in the Residential District.
   3.   Damage or Destruction. In the event that any structure described in Subsection 1 is damaged or destroyed, by any means other than intentional destruction, to the extent of more than 50 percent of its structural value, such structure shall not be restored unless it shall thereafter conform to the regulations for the zoning district in which it is located; provided, structures located on a lot that does not comply with the applicable lot size requirements in this section shall not have a side yard of less than five feet. When a structure is damaged to the extent of less than 50 percent of its structural value, no repairs or restoration shall be made unless a building permit is obtained and restoration is actually begun within one year after the date of such partial destruction and is diligently pursued to completion. Complete reconstruction of a nonconforming structure may be allowed through a conditional use permit if the structure is damaged or destroyed by natural means and not through intentional destruction or actions of the property owner or tenant. Reconstructed structures shall not be allowed to increase the level of nonconformity with regard to setbacks or lot coverage.
   4.   Abandonment. In the event that any structure described in Subsection 1 is abandoned for a period of 12 consecutive months or more, such structure shall not be resettled and/or restored unless it shall thereafter conform to the regulations for the zoning district in which it is located, provided that structures located on a lot that does not comply with the applicable lot size requirements in this section shall not have a side yard of less than five feet.
   5.   Moving. No structure shall be moved in whole or in part for any distance whatever, to any other location on the same or any other lot unless the entire structure shall thereafter conform to the regulations of the zoning district in which it is located after being moved.
