Where the Zoning Administrator finds that floor area is an inappropriate measure of damage or destruction, he or she shall determine the cost of repair or reconstruction of the building or structure to its previous condition. If such costs exceed fifty percent of the reconstruction cost of the entire building to the condition existing on the date of the damage or destruction, the right to maintain and operate such nonconforming use shall terminate immediately.
(b) If a building or structure occupied by a nonconforming use becomes obsolete or substandard, as determined by any applicable provision of the Codified Ordinances of the City of South Euclid, and the cost of bringing the building or structure into conformity with such provision exceeds fifty percent of the replacement cost of such building or structure on the date it is lawfully determined to be obsolete or substandard, the right to maintain and operate such nonconforming use shall terminate immediately.
(c) The lawful repair of any nonconforming use, as determined by application of the provisions of this section, shall commence within one year of the date of damage or destruction, or within one year of the date such use is lawfully determined to be obsolete or substandard, or the right to maintain such use shall be terminated.
