If the old siding is not being removed and the new sidiing and the old are plywood decorative siding a vapor barrier should not be placed.

If the new siding is plank style like cedar siding or cedar shakes a vapor barrier should be placed .

NOTE: should read moisture barrier .
A true vapor barrier is on the heated side of the wall in the house .
Expert:  Machinc replied 23 days ago.
A moisture barrier like "Tyvec or Hardie house wrap would be used . An airtight product should not be used as it can condensate and create moisture
