And now it's time for the Covid "I guess" lumber shortage

Thanks, The stringers are not cut(solid) which as you know makes them stronger than cut. A notched stringer is limited to 6' without support or a center stringer. A solid stringer can span up to 16' horizontal using 2x12 #2SYP or better, I did it that way on purpose. 75# PLF total load along the 12' horizontal face of the stringer is well within the carrying capacity of the lumber. Cutting stringers is a dreaded job. Plus I may redo it seems a bit steep to me, I think it is about 40+ degrees. Thanks for the input.

Lumber is priced similar to gasoline, you are charged the replacement price or "todays" price typically.
Yeh, but....
Your talking about strength of the stringer. The treads should be supported every 16" min for 2x's.

I used 2x12x36" SYP PT treads, I wanted more depth on the tread.

Got me 2nd guessing myself, I'm within limits 2x12x36" tread attached to solid 2x12 stringers w/2x4 ledgers(now I can sleep)
Edit: Found the charts

Sir, I deal with degree engineers on a daily basis. They will pull out a book answer on me all the time. In practical application it doesn’t work. Here is why...You are relying on that 2x12 and tread to carry the load. However, the design is wrong because the single point of failure is the 2x4 scrap piece holding the tread. Therefore, when they dry-rot or split they will fail because you do not have a second point of failure. Which would be the middle stringer. They will be solid for a yr maybe two, but after that I would not trust those stairs. I hope none of your family weights over 200lbs. I’m sorry to point this out. I been doing construction for over twenty years. I just want your family to be safe. That’s all, I’m not trying to be over critical of your work. Here is an example I fixed last week.

LOL I ain't a carpenter. My Gramps was, worked for the Forest Service for decades and built a number of lookout towers around here, some of them twice. And he's built a few stairs!!!!

This is/ was the "Clear Jo," was a work boat on Priest Lake (North Idaho). Gramps built/ rebuilt the cabin. For decades, a large print of this very photo hung in our living room. Those windows were cut with hand keyhole saws, and my aunts and my Mom had the cores, to use for butcher boards

I get your point, nice work by the way!
 
SE Texas is called the Piney Woods, trillions of cares of Pine timber. We pickup needed pressure treated lumber at the site, that is the mill and the vat right there. The is no shortage. Perhaps a shortage of trucks delivering to the retailer??
Demand at Lowe's et has been high ever since the stay at home Covid crap but there is NO shortage. I bet the mark up and profit from everything else in their store is way higher than LUMBER!!!!
 
I bought un-treated 2X4X8' at Lowes last week. $4.51 a board. I'd hate to build a house right now.
