Rough cut lumber vs dimensional lumber

1

Hi,
As I’m sure all you guys have found on inspections rough cut framing and of course the home owner says " it’s rough cut full 2x6 so it’s fine for floor joist".
What resources have you guys found for this? Materials that talk about the difference?
Thanks

there is quite a difference between old growth lumber and new growth lumber, which in particular are You talking about ???

This appears to be new growth yellow pine

Not knowing the grade of lumber can be a design issue, so to be safe I would have to use Grade 3 as a safety factor.

I’d ask the homeowner to produce the span table he used.

I wouldn’t. I would just note what I see and move on.
