dedicated line=holes in the drywall?

What crn3371 said, +1.

It depends on where your start hole is and finish. If your going over 4ft....you will. Or Learn to spackle...

Another +1 for @crn3371 ’s post. As a homeowner who’s moved a lot, I’ve learned running power can be simple and nondestructive, or it can be a royal pain.

A reputable electrical contractor told me the only reasonable way to get grounded power into our 2nd story room here was to run lines outside in conduit from the basement breaker box to the 2nd floor. I decided against it. In another house, it was trivial to run lines through the crawl space to a first-floor room.

Good luck!
