1301.06   EXISTING STRUCTURES.
   (a)   Alterations or Repairs. Alterations or repairs may be made to any structure without requiring the existing structure to comply with all the requirements of this Code, provided the alteration or repair conforms to that required of a new structure; however, if the structure is increased in floor area or number of stories, the entire structure shall be made to conform with the requirements of the applicable Code in respect to means of egress, fire protection, light and ventilation.
   (b)   Unsafe Alterations. No building, or building service equipment therein, shall be so altered or repaired as to be less safe or sanitary.
   (c)   Change of Occupancy. If the occupancy of an existing building is entirely changed, the building shall be made to conform to the requirements of the applicable Code for the new occupancy. If the occupancy of only a portion of an existing building is changed and that portion is separated from the remainder, then only that portion need be made to conform. (Ord. 46-13. Passed 5-28-13.)
