OK, a little advice and education here, please. Local building practice calls for your basic PT or redwood mudsill atop the stemwall, with the floor structure (rims/joists) landing immediately on top of the mudsill. Yet I see numerous photos and applications from elsewhere which clearly show another sill betweem the mudsill and the floor structure.
Can someone give me some reasoning one way or the other?
