I'm Lucy, and I'd be happy to answer your questions today.
North Carolina law allows 14 and 15-year-olds to work during non-school hours in specified non-hazardous, non-manufacturing jobs, for up to 40 hours a week when school is not in session. They're only allowed to work from 7 am to 9 pm (until Labor Day, then that drops to 7 pm). During school, they can work up to 18 hours a day, no more than 3 hours on a school day. A 15-year-old cannot work more than 8 hours on a non-school day.
There are several jobs a 15-year-old is prohibited from doing. The primary one that could be relevant to working in the home is baking (but they can prepare food). Take a look at this site to get an idea of what they may or may not do.
The child will have to get a work permit, even if they're working for a family business. Here is a link to the application:
