In determining the appraised value of any nonconforming structure, the cost of land or any factors other than those concerning the nonconforming structure itself shall not be considered.
Appraised value, for the purpose of this section, shall mean the market value of the structure as reported by the owner, based upon the market value of comparable structures in the City. Where the City and owner do not agree upon the appraised value based on said comparable, appraised value shall mean the value reported by a qualified appraiser, approved by the City, hired by the owner to determine the value of the structure.
