All decks are required to have inspections according to NY state building codes. They inspected the depth of the holes before the concrete was poured, then the framing, and a final inspection when it's complete.
Just seems nuts to me! The thing is out in the middle of a field and not anywhere near an occupied structure!
You would understand if the deck was attached to a house. The state would have a legitimate need to ensure that a domicile which may be sold to someone else meets code. But, as you say, a deck out in the middle of a field???? Where is the state's legitimate interest in that? Talk about government overreach! Oops! Gotta be careful here that I don't get on a soapbox and violate the TOS!
Deck looks good and the observatory is going to be great! Good work, Dan!
