The NRC's decommissioning rule does not distinguish between residential and 
industrial per se.  The limit is 25 millirem per year TEDE to the "average 
member of the critical group."  The difference between residential and 
industrial sites would be taken into account during the process used to 
determine how much material can be left behind before exceeding the 25 
millirem annual dose limit.  Such considerations are built into the D and D 
code, which I believe is the NRC code designed to assist imlentation of the 
25 millirem per year rule.  See 10 CFR 20.1401 et seq.
