I would consider a carport to be a damp location as it exposed to the outdoor environment.
NMC is allowed in a damp environment, NM and NMS are not.

Have you looked at 334.10(1). The issue I see is the damp location

I do!
Now I do see an issue with it being a damp area.

OK. You changed my mind.

I think a car port qualifies. Whether it is a damp area or not is something else. Since a covered porch is considered outside and thus damp, I am thinking a car port is as well.

I really don't see how a carport is not a damp location. If it is exposed or if the nm is run in conduit than UF- IMO. Of course most crawl spaces are damp and I have never seen nm affected by it-- I think NM should be rated damp location

I agree with Dennis.
