§ 151.05  EXISTING SIGNS.
   (A)   Reconstructing Signs.
      (1)   No sign heretofore approved and erected shall be substantially repaired, altered or moved, nor shall any sign, or any substantial part thereof, which is blown down or destroyed, be re- erected, reconstructed or rebuilt unless it is made to comply with all applicable requirements of this chapter.
      (2)   For the purpose of this section, SUBSTANTIAL REPAIR shall refer to:
         (a)   Any change in copy face not designed to bring the existing sign within compliance with this chapter; or
         (b)   Actual repairs made (not designed to bring the sign within compliance), the test being the actual cost of any such repair.  Such cost of repair, if in excess of 25% of the original cost of the sign, shall be sufficient for the purpose of this chapter to qualify same as a SUBSTANTIAL REPAIR.
      (3)   Any sign in existence at the time of the enactment of this chapter and for which a proper permit has been granted by the city, which permit shall not have been revoked at the time of the passage of this chapter, shall be allowed to remain in its present form.
   (B)   Repair of unsafe signs.  This section shall not be construed to prevent the repair or restoration to a safe condition as directed by the Building Official of any non-substantial part of an existing sign when damaged by storm or other accidental emergency.
   (C)   Relocating signs.  Any sign that is moved to another location either on the same or to other premises shall be considered a new sign and a permit shall be secured for any work performed in connection therewith when required by this chapter.
