ok
here is how it goes
you put in plans and prints for what you do
local area building code accepts them
they inspect your work
it is all up to local area code and inspectors as to what it is
ie when I started welding in Los Angeles
aws cert was a waste of money
LA city cert was the one you wanted
now times have changed
but still local building code apply
hope this helps
sincerely,
Kent
