The Board of Zoning Appeals shall have the power to authorize changes of lawful nonconforming uses as follows.
(A) A nonconforming use which occupies a portion of a structure or premises may be extended within the structure or premises as they existed when the prohibitory provision took effect, but not in violation of the area and yard requirements of the district in which the structures or premises are located. No change of a nonconforming use shall entail structural alterations or any additions other than those required by law for the purpose of safety and health.
(B) The Board may impose those conditions as it deems necessary for the protection of adjacent property and the public interest.
