nesparky it all depends on where you live.
It's up to the AHJ and prosecuters. Even if the adopted laws and regulations allow other trades to be prosecuted the AHJ has to get them to court.
Here in MA licensing issues are not handled by the local inspector although he certainly can turn you in to Board of Registration of Electricians.
I know RI works in much the same way.
The following quote comes from Massachusetts Board of Registration of Electricians
http://www.mass.gov/dpl/consumer/press2004/el102904.htm If you follow the link you can read about a few of the hearings.
The Board of Registration of Electricians licenses more than 29,300 electricians throughout the Commonwealth. In fiscal year 2004, investigators completed 764 inspections. The Board received 446 new complaints and resolved 262 complaints, held forty-six formal hearings, entered into twenty-three consent agreements, suspended three licenses, revoked 19 licenses and placed eight licenses on probation. The Board also ordered licensees to return $6,100 in refunds to consumers.
