Wow!
House sold 5 years ago without issue, so apparently GA is comparatively slack on these counts!
Kind of sad that I am not supposed to (legally) make modifications to my own home myself. However, I guess it is a sign of the times in that home are no longer life-long possessions!
Generally a home inspector (with modest knowledge of electrical) will check out the home before the sale to make sure it is of sound construction. They would check the outlets and such using one of these, and call it good if everything passed:
However, I just checked the panel for my current home (about 12 years old) and there are no certification stickers or anything like that!
Of course there is some horribly shoddy workmanship in many of the homes around here. If you look at home construction rates vs budget for Building Inspectors over the last 6 decades, it is apparent that the building inspectors are no longer able to perform proper inspections.
