Code Enforced = NFPA 101 2015

Citation= 101:8.6.9.1

Project Description =  Interior renovation of a two-story office space. Floor area = 15,680 sf. Cost of the renovation exceeds 50% of the appraised value of the property.

Occupancy Classification = Existing Business/New Business

Construction Type = V(111) Fully sprinklered.

Corridor separation = Not required by 38.3.6.1

 

Background: See attached floor plan diagram. The proposed design includes a new convenience opening per 8.6.9.1 as permitted by 38/39.3.1.1(1).  The AHJ has disallowed it citing non-compliance with 8.6.9.1(3), separation from corridors. The AHJ has interpreted that the unenclosed passageway alongside the proposed opening leading to a stair (guard on one side and partition on the other) is a corridor and must be separated from the convenience opening by a smoke barrier per 8.6.9.1(5). The Life Safety Code does not contain a definition of "corridor" but the IBC defines it as "An enclosed exit access component that defines and provides a path of egress travel." We also note that the LSC implies that aisleways between cubicles in an open office area are not corridors (c.f. 101:38.3.6.1(1)).

 

Questions: Is the unenclosed passageway a corridor and should the non-separated convenience opening be permitted?
