I am the fail at the Googles, as I ended up on some random pages that cited article 800 from a dated copy of the NEC.
When I spoke to Joe Holebrah (Delaware County) he stated anything lower than 50V is not inspected per state and he mainly inspects the cold air returns to verify no cable is run.
Plans for work: Running Cat6 to all the rooms, putting a small wall mount cabinet for a POP, running the Coax connections, HDMI in-wall - that stuff.
Now it's just dealing with Time Warner, ugh.
