BCAB #1774 - Exit through Lobbies

BCAB # 1774
Re: Article 184.108.40.206. Exit through Lobbies
The project is a sprinklered building containing multiple suites of residential occupancy, with one required exit from storeys above passing through the lobby. The lobby contains an elevator and an alcove where mailboxes for the building are located. The mailboxes are located on the interior side of two exterior walls.
Reason for Appeal
There is a disagreement on whether mailboxes for residents are permitted to be located within a lobby used as an exit.
The appellant contends that the mailboxes present a level of hazard that is less than those items specifically permitted in or adjacent to an exit lobby. The presence of mailboxes is consistent with the intent of the code. The mailboxes could be interpreted as complying with the literal provisions of the code for rooms.
Building Official's Position
The building official maintains that an exit lobby must comply with all the requirements for exits and may not be designed for purposes other than accessing or exiting floor areas as indicated in Sentence 220.127.116.11.(6). Permitted exceptions are found in Subclauses 18.104.22.168.(2)(e)(i) to (iv). Mailboxes are not included in these exceptions.
Appeal Board Decision #1774
The Board considers mailboxes located in a lobby used as an exit are incidental to the purpose of access through a lobby. Similar incidentals in lobbies used as exits include fire alarm annunciators and building documents such as a fire safety plans. Therefore it is the determination of the Board that these mailboxes are permitted in this lobby used as an exit.
