Mike:
I have to look into appliance repair guys here (NJ) as to what (if any) licences are required.
As to permits/stickers, I can only recall seeing a "call me' type label from the smaller repair guys. Permits are not required. There are also factory (mfg) repair/service guys, and large (Sears) retail ops that provide service/repair.
I see your point about shoddy repairs, and possibility of injury or worse.
Most, if not all the sparkies that I know....don't touch appliances. My personal thoughts over the years was and still is....do only what you do best; leave what you don't know alone.
