I don’t know whose bright idea it was to build garages and put only one electrical outlet in them. But it’s common in houses built before the 1970s. I don’t need to put the Taj Mahal out there, but I don’t like snaking extension cords across the garage to plug a tool in. So here’s how to add an outlet to the garage from the adjacent room.
To add an outlet to the garage from the adjacent room, knock out the metal knockout in the electrical box in an existing outlet, then drill through the drywall on the other side. Run a wire from the outlet to the other side. The project only requires a wall-mounted electrical box, a short length of wire, a cover plate, and a GFCI outlet if the circuit isn’t already GFCI-protected.
