As I said, I will check further.
It's a pretty fine line ... there's a term for the person who hires contractors to do a job; we call them "General contractors," and they need to be licensed.
Sure, there is some 'wiggle room' for others, such as architects, property managers, realtors, interior designers, etc. My preliminary chat with the contractors' board suggests that THEIR opinion is that the guy needs a GC license.
However it shakes out, it is a lesson on point: not everyone you meet is necessarily your friend. Or, as an old saying has it: Trust your mother- but still cut the deck!
