I'm doing placement of electrical boxes for my basement. In the case of a lightswitch, should it go immediately on the double stud for a door frame (3 inches off the door), or should I add a small piece of 2x4 onto the double stud and place the light switch box on that (4.5 inches off the door)? My door trim will be about 2.75 inches, covering part of the door jamb and part of the studs. Would like to know what the standard practice is of folks, TIA!

Go around your house and decide which light switch is your favorite to use, then make the new ones that far away from the door.

I find that if they're too close to the door, they feel awkward, like, I have to stop and actually hit the darn thing, where as if they are a reasonable distance away, I can just flick my hand back and get them on the way in.

Check the nfpa code on this one to be sure your choice is okay

Unless something has changed drastically in the code in the last edition, there isnt a set distance from the doorway for light switches, at least in the US. Besides, it's old construction, and code device distancing doesn't really apply.

Height matters more than anything. As long as the trim doesn't interfere with your switch plate, it's good. You can always leave extra wire to the box and see how it feels in one spot, and then move it if you have to.

If you're getting it inspected, put it where you want and see what the inspector says. If you left extra wire it should be trivial to move.

Just make sure your trim doesn’t interfere

Add the blocking first is pretty standard

Nothing worse than a switch in the way of the casing

I would add the blocking. Sure 3 inches is enough for your casing but down the road if you go to a bigger casing you'll be glad you left wiggle room

Its not a standard distance:

Its usually mounted to the nearest stud to the doorway that isnt part of the door frame. That usually puts it within a foot of the doorway. Standard stud gaps are 16", but the doors tend to encroach on that a bit.

But sometimes it ends up mounted to the doorframe stud, anyway. If the frame is thick enough, and there isnt much trim, thats not a problem.

As close to the door as possible
