LV requires a permit and inspection in two areas here though no license is required
. There's a lot of office and commercial buildings but a disastrous fire at a hotel/conference center years ago got the AHJ's to strenghten requirements.
I read the article and I thought that the NEC always prohibited LV wiring on the ceiling grid. (Don't make me look it up
) My subscription to that trade journal stopped for some reason a long time ago. Just as well, old Donna wasn't always spot on with everything she wrote about and she kind of annoyed me.
