2015 IBC/IFC FIRE AREA. The aggregate floor area enclosed and bounded by Fire Walls, Fire Barriers, Exterior Walls or Horizontal Assemblies of a building. Areas of the building not provided with surrounding walls shall be included in the fire area if such areas are included within the horizontal projection of the roof or floor next above.
Fire Walls etc are italicized in printed code, meaning they’re code defined terms. But this is work product of the architect, as approved by the building department. Plans for a building permit that do not show any Fire Area’s, except for a Fire Area that includes the entire building, are not accepted for submittal. Without this information even the fire plans reviewer can’t start work on their part of building permit review. If I had questions conflict between shown Fire Areas, allowable areas calculations or some other basic problems with submitted plans expect me representing fire to stand at the building reviewers desk to talk about it. That’s what elevators are for. You can’t do a review down to say, talking about detection for fire/smoke dampers if the basic design is flawed or incomplete. Best.
