I am running some new romex for a couple of electrical outlets. One of the outlets is on one side of a wall in one bedroom and the other outlet is on the other side of the wall in another bedroom. When I went in my crawl space to see what was below the wall cavity, I found two floor joists running right underneath it. Based on my measurements, I'm fairly certain I have no room underneath on either side of the double floor joist to drill up into the cavity. If I were to drill right next to the joists, I'd be going up into my button board rock lath walls.
Do people drill vertically through floor joists? If so and if there are two floor joists together, does one drill the hole in one of the joists or right at the seam between the two? Or do I drill a hole diagonally through one or both? In case it would affect the hole size, I'm using 12-2.
