Anyone know about AR2a zoning and tiny home short term rentals?

[Neil Tidwell]

I have been looking at the Nashville market to buy 5+ acres, owner occupy the main dwelling and build tiny homes or other accessory dwellings on the property for short term rentals.

From what I gather, AR2a zoning (which nearly all these sorts of properties are) disallow accessory dwellings, but somehow allow mobile homes, accessory apartments, and two-family dwellings. I know getting permitted as an owner occupied short term rental is possible in the zone, but not sure if any sort of detatched structure would be allowable. 

Is detatched short term rentals just not feasible within Nashville zoning?
