1022.1 Enclosures

[Ktoby]

Good Morning,

I am looking for 2022 CBC/IDC code language that was in I beleive the 2016 code. Not sure if it was moved or omitted. It used to be section 1022.1 Enclosures Required, specifically exceptions 1.1 and 1.2 code as follows:

1022.1 Enclosures required. Interior exit stairways and interior exit ramps shall be enclosed with fire barriers constructed in accordance with Section 707 or horizontal assemblies constructed in accordance with Section 712, or both. Exit enclosures shall have a fire-resistance rating of not less than 2 hours where connecting four stories or more and not less than 1 hour where connecting less than four stories. The number of stories connected by the exit enclosure shall include any basements but not any mezzanines. Exit enclosures shall have a fire-resistance rating not less than the floor assembly penetrated, but need not exceed 2 hours. Exit enclosures shall lead directly to the exterior of the building or shall be extended to the exterior of the building with an exit passageway conforming to the requirements of Section 1023, except as permitted in Section 1027.1. An exit enclosure shall not be used for any purpose other than means of egress.

Exceptions:

1. In all occupancies, other than Group H and I occupancies, a stairway is not required to be enclosed when the stairway serves an occupant load of less than 10 and the stairway complies with either Item 1.1 or 1.2. In all cases, the maximum number of connecting open stories shall not exceed two.
1.1. The stairway is open to not more than one story above its level of exit discharge; or
1.2. The stairway is open to not more than one story below its level of exit discharge.

Any thoughts?
Thank you

That's not what you were looking for. Your opening post addressed enclosures for exit stairways and exit ramps. That's the corresponding section I found for you. Section 1019 addresses exit access stairways and exit access ramps.

Okay, sorry??

No need to apologize. YC doesn't mean for it to sound the way it sounds.

I looked for those exceptions
