Acceptable cuts in 2x10 band joist


I need to cut a semi-circle out of 2x10 band joist so I can run conduit up from my first floor (I'm installing coax and network cable). Can I safely cut a 1 inch diameter semi-circle out of the inside edge of the 2x10 or will that ruin the integrity of the board? This cut will fall about center between two joists.

Here's a link to a rough drawing of what I'm talking about in case I can't figure out how to attach the picture to this post. Thanks for any help!

You should be fine with that.

In NY, this would be a rim joist over a sill plate.

I doubt you need to use conduit for coax and network cable. If you want to set it up so you can add additional cables later you could just include a pull line with the initial bundle you snake through.

The primary things to watch for would be the attachment of something (for example a porch ledger) through the thinned portion of the band joist, or a highly concentrated point load (for example the post supporting one end of a heavily loaded header) applied at that point.

Not likely problems, but still things to keep in mind....
