Who was this guy from? Was he a building inspector, zoning, "code enforcement" (the "junk car in the yard" guys) or was he the tax man?
It is unclear from your post what he wanted.
On my remodel, I saw the various trade inspectors and the tax man but that was right on schedule. They look at everyone every 2 years.
Sometimes our code enforcement people use the life safety excuse to look over a place when they suspect a non-conforming occupancy.
