I have a new construction 5-story residential (dormitory) being constructed under UFC.
The architect inquired if lobbies need to be provided for the elevators, and, if not, do smoke protection (draft-curtains) need to be provided?
My immediate thought was of course, something needs to be provided. However, when I follow the code track of NFPA 101, it is not exactly clear in comparison to IBC.
The IBC is very clear, Section 3006 regarding the protection of hoistway openings.
Without going through the entire NFPA 101 code-track here, we end up back at NFPA 101 Chapter 8. Section 8.5.3 states a fire barrier can be used as a smoke barrier, provided it meets the requirements of Section 8.5. Hoistway openings, specifically elevator doors are not specifically mentioned in NFPA 101 Section 8.5. The only thing I can point to is Section 8.5.2 Continuity and Section 126.96.36.199 Joint Systems for Fire Barriers.
Other items: The hoistway is to be protected with a 2-hour fire rating, which requires the elevator door to be 1.5 hour rated (Section 8.6.5), and the building is protected throughout with automatic fire sprinklers, including the elevator shaft.
By definition, the building is not considered a high-rise. The hoistway height is ~57 feet.
What are everyone's thoughts on this?
Thanks in advance.

I recommend clarifying with the Design Professional what the adopted Code(s) (IBC? NFPA 1? NFPA 101?) the project is required to meet ... “UHC” is no longer maintained :

I'm thinking that the UFC being referred to is the Unified Facility Criteria developed by the Department of Defense, which for construction specifies the use of the International Codes for construction, except that NFPA 101 be used for egress requirements.

Dwight - You are correct.

Since the 2021 NFPA 101 does not include prescriptive requirements for “hoistway protection” as the IBC does, the fire-resistance rating (FRR) of the shaft enclosure would need to meet 2021 NFPA Chapter 8 Features of Fire Protection and Chapter 28 New Hotels and Dormitories ...

Todd - Correct. We arrived at a similar conclusion. We will be providing a 2 hour rated elevator hoistway based on the requirements of 8.6.5 and 188.8.131.52.2.
