My guess is that if someone does something for free the Florida law wouldn't apply to them. If I mow my neighbors lawn I'm not a lawn care company, fix is sink I'm not a plumber. You can require a lot of someone when they are getting paid as that becomes a contract, but when it is free it is harder. My guess is that if there was a problem it would end up being a civil issue, not a criminal one. Not that it wouldn't suck in either case.
The absolute reality is you have a zillion laws on the books, more everyday. Most are not enforced. Not saying anyone should break any laws, you shouldn't.
