Hi there.
I am buiding a room in my garage and I am now framing an opening for a prehung door. I decided that one side of the door (the hinged side) will be exactly against an already existing 2X4 upright stud between my top and sole plates. do I need to double up the stud with another stud or attaching the jamb to the pre-existing stud is good enough??

Obviously on the other side I will frame a new stud to the full length and a support horizontal at the top to be attached to the top jamb.

Thanks in advance,

Is this in a new wall or an existing wall? Is the wall load bearing?

I believe you'll need to make https://www.flooringclarity.com/what-ha ... etime-com/ to "support the header and transfer structural weight from the header down to the floor. Trimmers serve as framing for nailing side jambs."

Here's a door framing how-to. I think only Step 1 applies in your case, since Steps 2 and 3 apply to those who aren't using a prehung door.

Knightfly and I both own Builder's Essentials: Framing & Rough Carpentry by Scot Simpson, and we both recommend it highly.

HI there and thanks for te reply.
I don't think the wall is load bearing... It is a new wall I framed inside my garage so it doesn't support the ceiling or anything.
I attached the bottom plate using read head concrete bolts and simmed the top plate and nailed it to the ceiling studs.
That's what makes it not load bearing right?

As for the framing of the diir, I know about trimmer studs but I was puzzled whether I should double the studand nail the jamb to it or I can use the frame stud for that purpose.

Any thoughts?

I'm not the expert on this, but I would suggest following the trimmer stud illustration on the linked page above. I'm pretty sure that's what code requires.

Depending on the weight of the door, its a good idea to put an extra stud there. The hinge side of the door takes the brunt of the doors weight.

The extra stud also helps to keep things rigid and straight in that area. The other side of the door frame is not as critical but should also have an extra stud. Framing lumber has a way of twisting and bowing when it drys, nailing 2 studs together keeps things straight and true over time.

Thanks for the tips guys.
OK I would put extra studs but since my frame is already upright in place attached to the ceiling and concrete floor, how do I nail a stud to the top and bottom plates

L brackets?

Thanks,

You toenail it. Drive a nail on an angle up or down into the plate. 2 nails on each end.

Then at 12"- 16" intervals you'll nail 2 nails ,side by side, up the face of the stud so that the 2 studs essentially become one solid member.

how wide and how tall is the prehung door you are puting in. some pics would be nice also to make it easier for us to help you.
