Variances from the provisions of this title shall be granted only when, because of special circumstances applicable to the property, such as size, shape, topography, location or surroundings, the strict application of this division deprives such property of privileges enjoyed by other property in the vicinity and under identical zoning classification. Any variance granted shall be subject to conditions to ensure that the variance does not constitute a grant of special privileges inconsistent with the limitations upon other properties in the vicinity and in the same land use category as the subject property.
