Owner's electricity cut off, hasn't paid dues...

We have an owner who hasn't paid his dues in 3 months and who apparently has also had his electricity cut off recently for non-payment. He is still 'living' in the unit without electricity. We have a process to handle the delinquent dues once owners hit 90 days late so that part is covered. Our concern is that waterlines might burst during some of our cold nights and create a bigger problem. If he isn't paying dues or electric bill, I'm guessing he won't pay it just to keep the pipes from bursting, even if we require it under owner required repairs.

Has anyone ever had this situation? We are in NC.

Thanks in advance.
