I'm converting the breezeway of my 1950's era house to living space. I need to make the shared wall of the garage and new living space fire-rated. I understand the insulation and sheet-rocking requirements. My question pertains to the wiring. There's a lot of wiring along the face of the top plate of the common wall that will have to be re-routed in order to put the sheet-rock up. What is the best approach for this? Can I take it off the wall and surface mount it in some way or simply staple it to the bottom the garage rafters just a few inches away from the sheet-rock?
