So I had my house completely replumbed, but I am concerned that my plumber may have screwed up.
As far as I can tell, I have a single cast iron vent stack (at least 4" and the house is wet vented. Everything that drains (save the basement floor drain) is close to the main stack. But the toilet and bathtub are on the second floor and the kitchen sink is on the first floor. This means the toilet is draining into the main stack that also drains the kitchen sink which is situated one floor below the toilet. The kitchen is directly below the bathroom, and both the bathroom and kitchen are being drained (and vented) by the single main stack.
Is this a problem?

if the plumber is planning on using AAV's you should be OK.
check with the inspector as he/she has the final say.

AAVs may meet MINIMUM code but, IMO, are NOT good practice
they are mechanical devices with MOVING PARTS which will, eventually, fail
if they fail closed they merely need replacement
if they fail open they will pass sewer gasses into your living space
or
simply vent the fixtures as per good practice from the get go

my friend from SC...
i could not agree more !
we are looking at a new generation of plumbers who wouldn't know how to vent a 2 1/2 bath house with kitchen, bar sink and laundry.
just slap an AAV behind the trap and collect your check.

depends on how the plumber spent their apprenticeship.
If they completed their OJT hours working service with no new construction I'm inclined to agree with you about not knowing how to vent per code.
But anyone who went through the apprenticeship working new construction (residential or commercial) will know how to vent.
