BCAB #1658 - Stair dimensions for handrails, Sentence 184.108.40.206.(1)
May 28, 2009
Re: Stair dimensions for handrails, Sentence 220.127.116.11.(1)
The subject is a stairway.
Reason for Appeal
Sentence 18.104.22.168.(1) requires handrails on both sides of a stairway which is 1 100 mm or more in width.
Sentence 22.214.171.124.(1) indicates that where a building is altered or repaired, the building performance shall not be decreased below a level that already exists.
The appellant contends the width of the stairway can be measured from the handrail and not from the wall which it is attached, as the portion of the stairway below the handrail is not usable.
Building Official's Position
The Building Official’s contends the width of the stairway should be measured from the ends of the stair tread, i.e. the width of the stair tread.
Appeal Board Decision #1658
It is the determination of the Board that the width of a stair is measured as the width of the stair tread. Therefore, the stairway(s) in question would require a handrail on both sides.
