I need to add a dryer vent pipe in my crawl space and route it to an outside wall.
Currently there is no connection under the floor - just a hole (see picture).
There is a narrow gap (about 1.5 inches) between the floor joist (right side of picture) and the termite shield.
Someone suggested adding a sister to that joist and then cutting a notch in it to allow vent pipe access.
Alternatively, I wonder if it makes any sense to notch the cinder block below the termite shield, patch the shield, and not have to notch the joist.
It seems like less work than putting in a sister. Would that violate code or be wrong in some other way?
