The Board of Zoning Appeals may allow the nonconforming use of a building or structure to be changed to another nonconforming use of the same or of a more restricted classification, provided no structural alterations except those required by law or ordinance are made. However, in an “R” District, no change shall he authorized by the Board of Zoning Appeals to any use which is not a permitted or conditional use in any “R” District, and in a nonresidential district, no change shall be authorized to any use which is not permitted or conditional use in that district where the nonconforming use is first listed.
