Anyone who contracts to perform work that is valued at $500 or more for materials and labor must hold a current, valid license in the specialty for which he/she is contracting. Section 7030.5 of the California Business and Professions Code requires that licensed contractors include their license number in “(a) all construction contracts; (b) subcontracts and calls for bid; and (c) all forms advertising, as prescribed by the register of contractors, used by such person.”
A contractor's license can be verified through the Contractor License Board.
