15.7.3: NONCONFORMING STRUCTURES:
Where a structure exists on the effective date hereof, that could not be built under the provisions hereof by reason of restrictions on area, lot coverage, height, yards, location on the lot, or other requirements concerning the structure, it may be continued so long as it remains otherwise lawful, subject to the following provisions:
   A.   Alteration: No such nonconforming structure may be horizontally or vertically enlarged or altered in a way which increases the nonconforming floor area, or moved in a way which increases its nonconformity.
   B.   Remodeling Or Addition: A nonconforming structure may be remodeled or added to, provided that the remodeling or addition or the use thereof, will not create a violation of any provisions of this title.
   C.   Reconstruction: In the event more than fifty percent (50%) of such nonconforming structure shall be rendered unusable, it shall not be reconstructed except in conformity with the provisions of this title or with action taken by the zoning board of appeals.
   D.   Exception; R-1 District: Structures located within the R-1 low density residential district which existed in 1974 may be reconstructed utilizing the existing footprint. The structure may not be reconstructed if it was built over a property line when originally constructed or is not in compliance with the permitted uses allowed within the R-1 low density residential district. Any reconstructed structure shall comply with all current building codes adopted by the city.
   E.   Exception; Location: Structures that were previously located in land outside of the city's zoning jurisdiction, but were later zoned as part of the zoning expansion in 1998, or as part of a future expansion, may be reconstructed utilizing the existing footprint. The structure may not be reconstructed if it was built over a property line when originally constructed or is not in compliance with the permitted uses allowed within the existing zoning district. Any reconstructed structure shall comply with all current building codes adopted by the city. (Ord. 2014-09)
