BCAB #1375

Re: Stair Design for Single Family Dwelling, Sentence 3.3.1.15.(2)

Project Description

This appeal concerns the design of the primary stair (see Fig. 1) serving the three floors of a new single family dwelling.

Reason for Appeal

Article 3.3.1.15. provides the design criteria for stairs And Clause 3.3.1.15.(2)(d) requires the front edge of the treads to be at right angles to the direction of travel.

Appellant's Position

The appellant contends that the stair meets the requirements Sentence 3.3.1.15.(2). This contention is at least partly based on previous acceptance by another building authority.

Building Official's Position

The building official maintains the stair does not meet the requirements of Clause 3.3.1.15.(2)(d).

Appeal Board Decision #1375

It is the determination of the Board that the stair design in question does not meet the requirement of Clause 3.3.1.15.(2)(d) because even when using the handrail the path of travel may not be at right angles to the front edge of the tread.
