Why do you need 2 step high, how much did you have before insulating?
Or are you talking about the bottom of the main stairs?
Why do you need 2 step high, how much did you have before insulating?Installing 2 winger steps at the bottom of an existing basement staircase because insulating a wall in the basement is not leaving a 36" landing at the bottom.
However, doing so will require me to "create" headroom to achieve the 80" required on these bottom two steps.
The first floor joists that are "in the way" are beneath a tiny closet that is inside the box that is created by the sistered floor joists used to create the stair opening.
1) Can I reduce the two existing floor joists to 2x4's with hangers legally since the span of these 2x4's is so short? I'm guessing the answer is no.
2) Do I have to lose the closet entirely and just open up the rest of the opening?
3) Or, do I just have to give up the bottom of the closet on the first floor by adding some kind of 2x8 "deck" above the floor to keep LL intact?
This is finishing a basement in MA. Can add pictures/dimensions, just not sure what the best grandfathered play is.
The pictures I added should help, its the bottom of the main stairs. There was about 30" there before I added the R-5 foam board and 2x4 wall, which even if I left it there bare cement would not qualify as a legal landing as it was < 36".Why do you need 2 step high, how much did you have before insulating?

You can do just about anything with the floor under the closet.![]()

Here are some pictures to see the challenge.
Yes, All I could see was the beam so I went for that.Thanks yes, very clear on how the bottom should be built. It's the headroom problem at the top that I am challenged with. Thank you for your engagement and feedback, the challenge is how to solve for the 80" on the 2nd step.
That's the part I'm stuck on solving.
If your goal is to meet Code so that it passes inspection, then please note this:
"Winder stairs are permitted in the building code as of 2019. The code says the minimum tread width on the inside radius needs to be 6 inches. It also says that the tread depth at walk line of the stairs measured 12 inches in from the inside tread edge must be no less than 10 inches."
You do not meet minimum tread width on the inside radius. Yours is zero inches, but min. tread width is 6 inches.
