This happened to me about 3 or 4 years ago. I was wiring an addition to the back of the house, adding 2 bedrooms. I looked at the jobsite when I gave my bid. 6 weeks later GC calls and the job is now ready to rough in. I go and find the kitchen is in the process of getting remodeled and there is new wiring going on. I questioned GC, he says owner hired her own people, not his job and he has nothing to do with it. At this stage handydandy electric and drywall is covering with sheetrock. I finished my rough in, called for inspection, and informed inspector about the kitchen work. Drywall came off the next day. Owner asks me if I can cover with a permit for handydandy. Nope. Find somebody else. So she did. She was not my best friend after that, but I still work for the GC that did the addition. I just do not support unlicensed work, no way, no how. Hope she found out that cheap is not always so cheap after all......
