Group A-3 on 2nd floor

[Michael Lukacs]

Is an exit to the exterior required for a group A-3 space on the second floor with and occupancy of less than 100?

Yes but you will have to sprinkle the entire building or create a 2 hour horizontal fire barrier which includes supporting construction of the horizontal assembly

[F] 903.2.1.3 Group A-3.
An automatic sprinkler system shall be provided for Group A-3 occupancies where one of the following conditions exists:

1. The fire area exceeds 12,000 square feet (1115 m2);

2. The fire area has an occupant load of 300 or more; or

3. The fire area is located on a floor other than a level of exit discharge serving such occupancies.

Thank you for your response.
To clarify:
-The building is sprinklered
-The Group A-3 is an Accessory to B Assembly occupancy on second floor with less than 300 occupants.

Is a dedicated exit to the exterior required or is it acceptable to share the other exit stairways on the floor? (per IBC/CBC)

Stairs can always be shared with all floors unless there is some very limited exception that I have never come across....But it may have to DISCHARGE to the exterior if that is the question...I assume we are talking about enclosed stairs?

Yes, the exit stairs would have to egress directly to the outside - only 50% of
the stairways are allowed to exit inside the building which leads directly to
the outside.
