Basement Bathrm. fan vent - through the joist or though the wall?
Posted by David on January 21, 19101 at 22:07:05:
I'm installing a bathroom vent fan in a basement bathroom. By far the easiest way to install it is to cut a hole in the rim joist to vent it outside. But is this structurally sound (and does it pass code)? The hole needs to be 3" in dia. and the rim joist is a 2" X 8". The alternative is to drill and chisel a 3" hole into the poured concrete basement wall.

Thank you in advance?
