I'm 99% sure these stairs are good, but please tell me if I messed up!


Recommended Posts

I'm on IRC 2018.

 

I'm detailing out my floor heights. I've got a really big family room in the walk out, so we're using 16" trusses to avoid posts.

So I've very carefully stacked my basement and 1st floor defaults with the exact heights of everything we're using and then I reran the stairs.

 

I've got 6'11" from the nose of the step that hits the ceiling and the next step up has all air overhead, so I think that means I got an extra 3" overhead.

And my rise and run are within limits, but treads are < 11" so I have 1" nosing as required.

 

I'm not required to have a landing, but I do because it looks nicer from the great room.

 

So did I get it right?

I'd think about going to a 7 3/4" riser.  This would eliminate one tread and, IMHO is more comfortable to climb than a 6 13/16" riser.

Thank you, thank you.

That was a great suggestion. It auto calculated to 7-1/4" rise and I ended up with a few more inches of headroom and a slightly smaller stairwell.

Win, win!
