Other considerations aside (such as increased fire area as well as
the whole issue of mixed occupancies) let's say we are starting with
a building that a 13R system is acceptable. The answer is that you
are on the right path but 1500 sf is not the only answer. Outside
the dwelling unit (barring exceptions), you do have to follow 13 for
the discharge criteria ALONG WITH ITS MODIFIERS. Although not part
of the question allow me to say (due to extensive misunderstandings)
that you do not apply all of 13, ie locations such as concealed
combustible spaces or hose demand.

Dwelling
Unit" as essentially requiring me to do a 1500 sq. ft. calc for the
most
remote portion of the common area? The conditions of 6.7.2.2 are
not met in
that many rooms exceed 500 sq. ft.
