(A) Neither the Commission nor the Council may grant a variance from the terms of this title, including any requirement provided therein, unless it has first found from the evidence admitted during the hearing before the Commission or Council that because of special circumstances, applicable to the subject property, including size, shape, topography, location or surroundings, the strict application of the terms of the zoning regulations from which the variance is being sought deprives the subject property of privileges enjoyed by other properties in the vicinity and under identical zone classification.
(B) At the time of granting any variance, the Commission or Council shall impose thereon such conditions as will assure that the adjustment authorized by the variance shall not constitute a grant of special privileges inconsistent with the limitations upon other properties in the vicinity and zone in which subject property is located and further assure that the variance shall not adversely affect property and the use thereof in the vicinity of subject property and the public health, safety and general welfare.
