Please explain.

I know a local house wired and inspected in 1981 with no GFI. The NEC
required GFIs for bathrooms as of 1975. Evidently the local code hadn't
yet adopted that.

THE GFI outlets I've seen require a grounding wire. My bathroom would
have to be rewired from the breaker box. The NEC didn't require
grounding wires in bathrooms until 1962. In many areas, the change may
have come years later.
