I am working a project in my home where we are remodeling our wall where our fireplace is. I removed all the brick fixed some dry rot. Now I am getting ready to sheetrock, but before I do, I wanted to run some power to that side of the wall so we can hang out TV over the fireplace ( which we do not use). Anyway in my stupidity I used my 1 in bit to bore through the two corner studs (load bearing) to run the wire. Because the studs are offset from each other the hole is very close to the edge of each stud. Essentially creating a one inch notch. Living in earthquake land I would like the corner of my house to be as strong as possible. My first thought was just to sister in a stud, but the bottom plate bolt is real close but I can squeeze one in, and to make matters worse there must of been a repair to that wall before I owned the house because there is a 2x4 nailed horizontally to the sheathing any sistered stud will need to be notched 1.5 to accommodate the 2x4. The 2x4 is about 18 off the ground and the notch is about 12 off the ground. If I scab in a 2x4 that is 18 high it probably would do any good? Any Ideas?
