The city council may authorize in specific cases such variance from the terms of the zoning ordinances and regulations in effect as will not be contrary to the public interest where, owing to special conditions, a literal enforcement of the provisions of the zoning ordinances and regulations would result in unnecessary hardship. No nonconforming use of neighboring lands, structures or buildings in other districts shall be considered grounds for issuance of a variance. Variances shall not be granted on the grounds of convenience or profit, but only where strict application of the provisions of the applicable zoning ordinances and regulations would result in unnecessary hardship. (Ord. 341, 9-10-1996)
