Stair "flare" and handrail extensions

[Yikes]

Both an exit code and a CBC 11B accessibility question - -
Is a commercial stair allowed to "flare" to one side on its first riser+tread?
If "yes", is the bottom handrail extension allowed to turn to follow the flare?

It is similar to this:

Interesting question. At first glance I would say no that is not allowed. I am frequently wrong when it comes to plan check dilemmas.....but I would bet on this one.....just not a lot.

No, if the step was a curved radius and the handrail followed the radius of the step flare (think monumental stairs in old southern houses) where the stair tread ratio of width X length is maintained perpendicular to the handrail - this should not be an issue, but having the walking surface drastically reduce from 11 " to less than 9" is going to break a lot of ankles - especially for people who are dependent upon the handrail for stability.

CBC 1011.5.4 Dimensional uniformity: "...Stair treads and risers shall be of uniform size and shape...."
CBC 1014.6 Handrail extensions: "...The extensions of handrails shall be in the same direction of the flights of stairs at stairways ...."

The step can flare, but the handrail &extension need to stay straight, otherwise provide a landing.

Thanks, everyone!
