Drilling through jackstuds

[Jacksnap]

Have a 18' horizontal supporting beam, 12 X 4 I think, and on one end it has 2 jackstuds for support with also a king stud next to it. So, there is three 2 X 4's side by side, two of which are supports for the overhead beam (single story resi). I'm doing renovation to kitchen area and when I removed the sheetrock I found 3 runs of NM (12 & 14) going through a 1 inch hole drilled through one of the 2 jack studs and the hole continued through the adjoing king stud. The hole is drilled into the narrow face of the jack stud at a 45 degree angle, then continues through the king stud wide face. The second jack stud adjoing is untouched and the beam is untouched. Can I reuse this hole in the jackstud? :confused:

Jack studs, king studs, cripples, and normal bearing studs are grouped together in the same boring and notching rules. When you drill through the edge of a stud of any kind you created a notch.

Any bearing stud is allowed to be notched not to exceed 25% of its width.

Any bearing stud is allowed to be drilled not to exceed 30% of the width of the stud and is required to have that hole not closer than 1 1/2" from the edge or the stud.

You have a combination notch and bored hole both meeting the above rules as you have discribed it. You should be fine with this type condition.

However I wonder if your truly have a bearing header. Is the ceiling joist, floor joist, rafter bearing directly on this header. If not you could have installed as minimum size a 2 x 4 on its side. If this is truly a bearing header supporting a rafter, or floor or ceiling joist then I greatly doubt your header is adequate sized to carry your load. I would need the width of the building of the building [length of supported span or heal to heal of rafters to tell for sure and whether this is supporting a floor, roof, ceiling. Also would need to know location geographically to set the span per the IRC. Might want to recheck that header size and what it is truly carrying.

Wg,

Thanks for reply. I was definitly confused on code interpertation and if I could not reuse this bore, it would create a good day's extra work (working alone).
Yes, this beam is definitly what I described. The house is cement block all the way around with poured rebar reinforced header poured around top perimeter, and is generally 'L' shaped, 1 story FL style ranch with slab foundation. Has 'W' rafter system sitting on this beam for 18' and rest of same rafter system sits on cement block walls of house perimeter. The 'beam' has a 4 X 4 soild post in center (at 9') for mid-span support. This section of house extends beyond the 'W' rafter system to a 14' wide flat roof with 2 X 8's at 16" OC. One end of these 2 X 8's rests on the 'beam', the other end on the extended cement block wall. Thanks, again! :)
