Re: Egress / Exiting from Multi Level Residential Suites, Sentences 18.104.22.168.(2), 22.214.171.124.(1), 126.96.36.199.(8) and (9)
The subject is a sprinklered multiple suite residential building constructed under Article 188.8.131.52. The fourth and fifth storeys contain only twelve two level suites, each suite having an internal stairway connecting the two storeys. On the upper level (fifth storey), each suite has an egress door that enters onto a public corridor served by two independent exits. On the lower level, each suite has an egress door that enters onto a public corridor (dead end) served by one exit.
Reason for Appeal
Sentence 184.108.40.206.(8) requires each suite in a floor area that contains more than one suite to have an egress door into a public corridor. Sentence 220.127.116.11.(2) requires both the uppermost storey and the lowest storey of a dwelling unit containing more than one storey to have an egress door located not more than 1.5 m above or below its floor level. Sentence 18.104.22.168.(1) requires every floor area intended for occupancy to be served by at least two exits.
The appellant contends that Sentence 22.214.171.124.(6) states if a dwelling unit has a second and separate means of egress, one means of egress from a dwelling unit is permitted to pass through an interior corridor served by a single exit. The Code does not specify whether the interior corridor must be within the dwelling unit or could be a public corridor.
Building Official's Position
The Building Official contends that each level (storey) of the residential suite must have an egress door that enters onto a public corridor, and that each public corridor must be served by two exits.
Appeal Board Decision #1597
As the floor areas contain only dwelling units complying with Sentence 126.96.36.199.(2), they are exempt from the requirements of Sentence 188.8.131.52.(1). In addition, as the dwelling units comply with the requirements of Sentence 184.108.40.206.(6), they are exempt from the requirements of Sentences 220.127.116.11.(8) and 18.104.22.168.(7).
Therefore it is the determination of the Board that this design for egress from these two level dwelling units comply with the requirements of the Code.
