Right idea but wrong lobby. I looked back at information from the
code change (ROP and ROC).

Thanks for the background, it was informative.

No, a "dwelling" is a building with a "dwelling unit", so your
attached garage is still part of a dwelling.

But a detached garage is a commercial space? Industrial? It is
really difficult to write any code that applies to 'every
thing'. That is one reason the NEC changes every 3 years. And why
the AHJ is given final authority.

I don't know what a detached garage is (Occupancy U in the building
code?) but it is not a dwelling as far as the NEC is concerned. From
Article 100:

Dwelling, One-Family. A building that consists solely of
one dwelling unit.

Dwelling Unit. A single unit, providing complete and independent
living facilities for one or more persons, including permanent
provisions for living, sleeping, cooking, and sanitation.
