Does *all* contract work require a "commercial license"?

[Tamas Z.]

Hello,

I own a commercial property, and am wondering if there is a line in the sand as to when I am required to get a contractor with a commercial real estate license. For instance, if I'm doing anything mission-critical, like getting a new roof, of course I need a commercial contractor.

But what if it's a 'little' job, like installing a fence with a gate around some small area I want to protect? Is there such a line in the sand, or am I basically stuck with having to go commercial (i.e. more expensive for the same-ish quality), no matter how menial the job?

Thanks!
