NEC 210.12(A)

[kgault]

I am trying to fully understand this section. From my understanding in simple terms the home run needs to be protected with either MC, AC, or metallic conduit needs to be used as stated in section 210.12(A)(5), but I was looking at some new build homes last week and they obviously don't have any of that ran. The panel was still new and there were no outlets yet.
If they used AFCI breakers does the branch circuit still need to be protected? If the first receptacle in the line is AFCI does the branch circuit still need to be protected(on this new home)?

I understand that on existing wiring the branch circuit does not need to be protected, but any modifications to the circuit requires a AFCI receptacle to be installed at the front of the line, but this house didn't even have drywall or insulation yet so I am trying to figure out how that plays into this code since it's a new build.

Surely not every home builder around here is going to run EMT or MC/AC so there has to be something I am missing

Each of the six list items in 210.12(A) stand alone. You only need to use one of the six permitted methods. The most common, by far, is the method in list item (1).

Okay, thanks. So all new homes are required to install AFCI breakers to the area defined by 210.12(A). Thank you
