Standard for granting a use variance

In granting a use variance, the zoning board of review shall, in addition to the above general standards, require that evidence be entered into the record of the proceedings showing that the subject land or structure cannot yield any beneficial use if it is required to conform to the provisions of this zoning ordinance. Nonconforming use of neighboring land or structures in the same district, and permitted use of lands or structures in an adjacent district shall not be considered in the granting of a use variance.
