I went through the same things when I put in my pool.
The last check was to see that my backyard gate would latch itself if opened to a 90 degree angle and released. It did. It was to prevent kids from getting to the pool from an unlatched gate. The city inspector told me I was good to go.
The fence on the other side of my house was torn down because the pool company still had equipment in my backyard. An elephant could have walked into the backyard.
The inspector didn’t even mention that.
