Correct. A mezzanine BY DEFINITION occurs between stories and is NOT a story. Everybody take a deep breath - this isn't worth a long thread. The BO or FO may require standpipes but I would not agree with that interp.

Roisum, SET Sent: Wednesday, April 22, 2015 9:36 AM To: [email protected] Subject: RE: Standpipes IBC definition of a "Story" - That portion of a building included between the upper surface of a floor and the upper surface of the floor or roof next above. It is measured as the vertical distance from top to top of two successive tiers of beams or finished floor surfaces and, for the topmost story, from the top of the floor finish to the top of the ceiling joists or, where there is not a ceiling, to the top of the roof rafters. However, the commentary says, "All levels in a building that conform to this description are stories, including basements. A mezzanine is considered part of the story in which it is located." Now it seems as though you would not include a mezzanine in your measurement for standpipes as the height requirement is based on measuring to the highest story... "Class III standpipe systems shall be installed throughout buildings where the floor level of the highest story is located more than 30 feet above the lowest level of the FD vehicle access." Reed A.

There are all 1 story units on Level 1-3. Level 4 has 1½ story units. 1000 sq ft on 4th floor, then go up a set of stairs that is internal to the unit. The mezzanine/loft is about 400 sq ft. It will have a bedroom and living space up there as well as a bathroom. The architect has put confusing notes on the plan. No one can figure it out. They are conflicting about NFPA 13 then 13R then standpipes, then no standpipes. He has been asked to clarify, but it is taking longer than the builder wants. They are just trying to get some ideas to know how it may go. If this is a story that would drive standpipes, would it also not drive the building to an NFPA 13 system since it would then be 5 stories. If the mezzanine/loft does not count as a story, then it would be applicable for 13R. They are under 2010 edition. But, if the mezz/loft does not count as a story to drive it to 13, then does it count as an elevation to trigger standpipes? Lot's of questions. Not many answers yet.
