The brain seizure is that you're combining several things that don't really combine well.You've got the Primary/investment distinction down. 

In my opinion, a duplex constitutes two distinct dwelling units, and consequently the restrictions imposed by this section do not apply. 

Our audit is asking us to list all subcontractors, but there seems to be a distinction in TN between a subcontractor (who has to carry his/her own workers comp insurance) and an independent contractor, who works by themselves and does not have to carry workers comp.Do any of you TN folks have a knowledge base on this from past experience?

Something like a duplex to start, maybe a B class property (I honestly don't know exact distinctions of each class, but definitely want something safe in exchange for less cashflow at least for the first time).

There is a often a frustrating game of "herding cats" that can happen when trying to use a separate contractor AND a management company that is capable of integrating with construction thanks to both of the groups having distinctly different processes. 

The majority of single family homes in the district can be converted to duplexes (two family flat) or can have legal ADUs added, but the distinction depends on the underlying zoning.

It certainly has a discretionary aspect to it, but, if you include the area as more of a vestibule/coat closet area and make a clear distinction on the plans for the area you will be OK.
