Sometimes they check on home owners and some times they don't.
I got an inspector stopping work on my basement, a conditioned space,
because it didn't have enough insulation in the ceiliing - the floor of
my living room. The guy across the street had me design an addition
which was approved by board of architects and building department, then
built something different.. Complaints to the City produced shrugs and
"we can't be bothered with little stuff."
