UBC Section 1005.3.3 Exit enclosures, allows an exception for an exit stairway serving only one adjacent floor to not be enclosed. Section 1104.2.1, Items 1, 3, 4, 5, and 6 all state that an area of evacuation assistance shall be immediately adjacent to or directly connected to an exit enclosure. Section 101.3 states "Where, in any specific case, different sections of this code specify different materials, methods of construction or other requirements, the most restrictive shall govern. Where there is a conflict between a general requirement and a specific requirement, the specific requirement shall be applicable." With these facts in mind:

Question 1: On a floor where there is no exit enclosure due to the application of Section 1005.3.3, can any of the methods of construction listed in Section 1104.2.1, Items 1, 3, 4, 5, and 6 be used if an area of evacuation assistance is required?

1. Yes, either the vestibule of Section 1104.2.1, Item 4, or the area or room of 1104.2.1, Item 6 could be constructed adjacent to the location of an unenclosed stairway which is allowed by the code.
