Jay, Did you use a faced insulation? If you did --that's enough vapor barrier for this area.
Further north (Canada) a full plastic vapor barrier is expected.
There are a couple of members with more knowledge on this. Code allows faced insulation as a vapor barrier in Kane and DuPage county--not sure about Will county,but I'll bet it's the same.---Mike---
