There are two separate detached single-family 2 story homes on one lot/parcel. They are spaced far enough apart to not require exterior wall ratings, assuming an imaginary FSD line is established mid-way between the two. They do, however share a common, uncovered wood deck that connects the two upper stories, about 9 feet above grade. The deck also has stairs that serve as the means of egress for one of the homes. Since the shared deck extends to and over the FSD line, would it be correct to consider the deck a violation of Table R302.2.1(1) – a projection less than 2 feet to the line? 2021 IRC. Thanks in advance for looking.
