LK,

Being in NJ you know that we have the UCC which exceeds the NEC. However even here in NJ emergency work is allowed to start prior to permits being issued. However you must report to the local construction office as soon as possible to notify them of the work being done. After that you have 36 hours (I believe) in order to come into the office and pull a permit. After that you still have to get inspections and meet the code.
