Unlicensed contracting is part of California’s estimated annual $60 to $140 billion dollar underground economy. These individuals lack accountability, do not pay taxes, have bonds, insurance or workers compensation. It is not unusual for them to be involved in other illegal activities as well. They are unfair competition for licensed contractors who operate with bonds, insurance and other responsible business practices. The California State License Board requires every contractor to put his/her license number in every advertisement, including Craigslist.
