The NC law requires sanity for publicly owned sex-exclusive areas. But private businesses can still choose to let men into their women’s bathrooms if that’s what they want to do, at least to my understanding. Which is fine, I personally don’t think it’s too swift for culture, but hey women can choose not to do business with them if they think it is a big deal.

I think anyone offering the public a facility has to have them properly marked. That was true when we last built. The inspector had that on the check list, so it had to be part of some law someplace.
They can, of course, have single person facilities that are marked for use by either sex. But they have to be marked.
