Yeah, fire departments don't do that here in Germany as well... legal requirement is that the licensed professional has a license according to the norm DIN 14 406 pt. 4. I had a quick google about the situation in the US, turns out there seem to be zero requirements on who does an inspection [1] - utterly mind-boggling.

In your case I'd search for a company that is certified by NICET [2].
