Ed, The appendix of NFPA13R, 2019 has this that may clear things up for you. A.6.6.5 An example of an open or exterior corridor, stair, or breezeway is one that is exposed to the outside atmosphere (temperature). Another example is an exterior wraparound corridor that is typical in a two- to three-story motel.

One of the changes is in section 6.6.5 part (7) where it says "Corridors that are open to the outside atmosphere and are separated from the exit stairwell". In the 2022 edition, this is revised again to read "Corridors that are not part of a means of egress". The 2022 edition also has a new section 6.6.5.2 that says "Sprinkler protection shall be provided for corridors and balconies that are part of a means of egress." We're seeing more and more of these: 3-story 13R apartment building with 1 or more breezeways. Breezeways are open on each end, combustible construction, and have open stairs from 1st to 3rd floors. The ceiling of the 3rd level is smooth/flat gyp board. The ceiling of the 1st and 2nd levels are exposed wood joists. I assume the breezeway/stairs are part of the means of egress. Our area is subject to freezing. [cid:[email protected]] Is an open breezeway a corridor? IBC's definition of corridor says it's enclosed. If it's not a corridor then we don't have to sprinkler it because it falls in the "other similar features" category of section 6.6.5, right? Really curious how other jurisdictions are interpreting this. I appreciate your insight!
