BCAB #1487 - Sliding Door Exit from Secondary Suite, Sentence 126.96.36.199.(3) ('92 BCBC)
June 28, 1999
Re: Sliding Door Exit from Secondary Suite, Sentence 188.8.131.52.(3) ('92 BCBC)
The project in question is a new secondary suite in an existing house. An existing sliding glass patio door provides the only exit from the suite.
Reason for Appeal
Sentence 184.108.40.206.(2) requires every required exit door to swing on a vertical axis in the direction of exit travel. Sentence 220.127.116.11.(3) is an exception to the above and permits an exit door serving a dwelling unit to swing inward.
The appellant contends that the code does not prohibit a sliding door as an exit from a dwelling unit. Sentence (2) requires the door to swing outward and on a vertical axis "except as permitted in Sentence (3)" which "permits" the door to swing inward. The appellant contends dwelling unit exits are permitted to swing inward but could also slide because they are exempted from Sentence (2).
Building Official's Position
The building official maintains exit doors from dwelling units are only exempt by Sentence (3) from the requirement to swing in the direction of exit travel and must still swing on a vertical axis.
Appeal Board Decision #1487
It is the determination of the Board that the exit door from the secondary suite must swing on a vertical axis in accordance with Sentence 18.104.22.168.(2). Sentence 22.214.171.124.(3) only exempts doors to dwelling units from the requirement to swing outward, it does not exempt the requirement for swinging on a vertical axis. The Board noted that editorial changes have been made to the wording in the 1998 BC Building Code that has made this intent very clear.
