Does it make sense that someone is required to sell both sides of a duplex in NC?

I toured a duplex that is a new build and the developer said that he had to sell the units together, that it was required. Any insight on if this is a Charlotte or North Carolina limitation? I wasn't sure if it was just a limitation that he encountered as a developer or if as the new owner I would run into that should I ever need to sell in the future, just want to make sure that I knew more before jumping in.

Just a little broader comment on the topic....I've seen quite a few new construction homes that are 1/2 of a duplex. They're calling them duet homes. There's no HOA, the parcel is subdivided into two parcels so each home conveys with land.

Our new UDO for Charlotte is encouraging more higher density housing, so we may start seeing this more as builders are trying to build more housing on the same amount of land. If the zoning department requires a specific amount of road frontage for each lot, and that prevents the lot from being subdivided, then we may start seeing that more. 

Good question! I don't think I've run across that yet.
