According to jimbob :
I have been rewiring a dining room in a 1930's home. In new
construction outlets are linked together by wires running horizontally
through the studs. I haven't been able to find any guidelines for how
to run wires when rewiring. The most logical way seems to be running
wire through floor joists underneath the room in the unfinished
basement. I have a couple of choices. I can run wire from outlet to
outlet, passing the wire under the floor, or I can wire to junction
boxes under each outelt with a wire extending to each outlet. The
latter would allow me to use less wire and fewer holes through the
joists. The first way would mean that I would use fewer junction
boxes. Is there any advantage or disadvantage to either way? Anyone
know of any guidlines for rewiring? Most of the info I have found is
on wiring new construction.

I've done the j-box approach myself. The feeds to each outlet
box were AC armor, because it was thru a wall that was just
lathe over masonry. Saved a fair bit in armor cable costs.

Inspectors don't like seeing lots of unnecessary J boxes. J boxes
also may present some difficulties if you want to finish the basement.

An inspector probably wouldn't mind this.

However, for a single room you're unlikely to save enough money
to notice. Indeed, the jbox approach may be more expensive.
But quicker.
