Also called a sill plate, what is the name of the piece of wood attached to the foundation that has joists on top of it?
Answer Sole Plate
The sole plate, or sill plate, is usually attached to the foundation by bolt or strap. Joists that help create the floor system are then nailed to the sole plate to connect the frame of the house to the foundation.
