Redneck smoke test. Light a sealed pack of cigarettes, and
drop in. If that doesn't show any leaks, have Clark Griswold
pour in a gal of gasoline.

First, I'd call the city and ask if it is, in fact, "the
law", and
second, I'd ask if I could do my own smoke test. Can't be
too hard.
Just find your cleanout and insert smoke bomb. Also, you
might try
calling a couple more plumbers.

If you do your own smoke test, suggesting you put it into a
small can
with a wire through holes in the sides. Otherwise, the bomb
can melt
a portion of a plastic pipe.
