(A)   A nonconforming sign means any lawfully-erected sign or billboard that does not conform to one or more provisions of this subchapter or any amendment thereto.
   (B)   Any nonconforming sign that does not pose an imminent peril to life or property may lawfully remain subject to all the restrictions on the enlargement, alteration, relocation or reconstruction of nonconforming structures set forth in §§ 152.205 through 152.216; provided as follows:
      (1)   Merely changing the message displayed on a nonconforming sign shall not be construed as a prohibited alteration;
      (2)   Whenever any sign is nonconforming solely because it is appurtenant to a nonconforming commercial/industrial use located in the Agricultural District or in any residential district, the sign shall be treated in the same manner as it would be if it were appurtenant to a commercial/industrial use located in any business district or in the Industrial District.
