How close to the stairs can I put a door?

[DIYMyLifeAway]

I am remodeling the upstairs and would like to move the wall (red arrow wall) between the bedroom and bathroom as far into the bathroom as possible to make the bedroom bigger. How close to the lip of the top stair can I frame in a door?
Or if someone sees a better way to lay this out I'm open to all ideas. The grey box in the bathroom is a stairhead to provide headspace for stairs going down.

You will gain 2”. Is it really worth the effort? All the plumbing is in that wall, it is going to be difficult and expensive. And the doorknob will hit the wall when the door is opened. Bad idea.

I agree with e hilton - don't move the wall because the ROI isn't worth the expenditure. If anything, I'd spend the money on reversing the door swing of the bedroom door. That would also allow more natural light to spill into the hall from the bedroom.

Thanks for the replies. The drawing with the red arrow is my best shot of an "after". I'll post the current layout here. There's an odd angled hallway and I want to straighten that out to more of an "L". I'm hoping to shave off any area out the bathroom that I can since there's so much unused space in there. Even if it's only moving the door 7" closer to the stairs. But I'm also concerned that people will fall down the stairs coming out of the bathroom. I wasn't sure if there was code on that.

Good catch on the door swing! Thanks!

As long as there is a legitimate landing for the bathroom door you are able to do as you wish.
I posted your plans side by side for clarity. The first one is the before and then the aftewr.

Your did not state the project location, so we don’t know the locally adopted code.
Assuming this is a private residence under some variation if the International Residential Code, you can move the door all the way over until its opening aligns with the top riser of the stairs. Typically, on private residences handrail is only required along one side of the stairs, so you could put the hand rail on the opposite wall to help avoid conflict with the door trim.

P.S. You might find it more convenient to flip the door swing on the larger bedroom:

Thank you for the sketch! Good to know I have that room to play with the door location. The project is in Minnesota, hope that doesn't change anything.

My thought:



If the closet in the bedroom at lower right can be a tad smaller, you could also put that bedroom door on the diagonal. Or you could use that triangular alcove as a small linen closet.
