Maybe I need to start at the beginning ….
I need steps to get to the second floor of the workshop.
Rise / run … no problem, I can get that and make sure they meet code.
The problem is the top step ….
My original thinking was the stringer ended at the back of the first step (one step down from the floor) and tied into the header.
So my question was going to be how to I attach a tread nose to OSB sub flooring?
And this still might be the right question …..
Then I started looking on the web ….
Some sites say to have a complete top step as part of the stairway with the last tread being the same height as the sub floor.
Some sites show half a tread as the top step even with the floor.
Some do it the way I was going to do it … but they has a solid deck and let it stick out the same distance as the nose of the other steps.
So, is there a “best way” to build steps?
It makes a difference now as I need to know where to put the header that the steps run into ….. a double LVL.
Thanks …. Mike

Your original method is the way to go. Otherwise you're extending the overall run of the stair for no reason. Well, there is a reason and it has to do with resolving how the stringers attach to the upper framing. That's a lot simpler if there's a top tread that's flush with the floor - there's a lot of meat left on the stringers then to fasten to the framing. One solution is use the Simpson stringer connector: https://www.strongtie.com/deckconnectors_decks/lsc_connect/p/lsc
Thanks so much ... I had never used a connector like that. Seems much better than toe nailing.

They're game changers, especially if you use Simpson's hanger screws with them.
I was looking at the screws .... much easier when hanging off a ladder than pounding in nails ... well at least for a guy like me who does not do this for a living.
Thanks!
