East stair proportion?

[matt]

West corridor could be a dead end if >20' to midpoint of stair door? just move west corridor wall back like 10.'

[Coach]

East stair proportion?

Nope. Stair proportions are irrelevant as long as you have 8' min clear.

[Coach]

West corridor could be a dead end if >20' to midpoint of stair door?

Of course, but it isn't even close.

just move west corridor wall back like 10.'

Huh?

[Riety]

2nd floor is overhanging? Cause I do not see the floor below?

[Coach]

2nd floor is overhanging? Cause I do not see the floor below?

Nope. First floor is irrelevant in this exercise.

[fare75]

Recess depth at the west side between LM and SM, and recess depth at the north side between SM & OB?

[matt]

Distance between exits is closer than half of the overall building diagonal.

Nope.

[Coach]

Distance between exits is closer than half of the overall building diagonal.

That's it!

Now, what is the longest applicable diagonal.

[matt]

Probably net floor so LM corner to ST corner or SW corner to SM corner, whichever is longer.

[teelee]

This red diagonal is longer.

Distance is measured from stair door to stair door, right?

What are the max recess proportions allowed, btw?

Thanks.

OB doesn't count. It's not 2nd floor space.

Distance is measured from stair door to stair door, right?

Measure to center of doors, yes.

What are the max recess proportions allowed, btw?

I recommend depth no more than twice width.
