As my next move, I would send an e-mail to the 
Nantucket Building Inspector Mr. Alan Noll

Title: Local Building Inspector
Phone: 508-325-7587, ext. 7029
Email: anoll@nantucket-ma.gov

informing Mr. Noll:
a) that the framing at 3 Red Barn Road had been inspected in 2008,
and that approval had been withheld until rough wiring and rough
plumbing had been inspected and approved, and
b) that the rough wiring and rough plumbing has since been inspected
and approved.

asking Mr. Noll whether the framing inspection of 2008 suffices 
or whether it should now be repeated.

I would not ask for a repeated framing inspection unless I was told 
that a repeated framing inspection was necessary.
