Exception 4 of Section 708.4.1 is applied to a 3-story Group R1/R2 building. The building is protected throughout with an automatic sprinkler system and the corridors have a ½ fire-resistance rating. Hence, an enclosed elevator lobby is not required. Is the elevator shaft enclosure door opening required to comply with the smoke and draft control requirements for a door assembly in a corridor of Section 715.4.3.1 when opening into the fire-resistance rated corridor?
