(a) The Contractors License Board may adopt rules and regulations necessary to effect the classification of contractors and shall require a written examination in a manner consistent with established usage and procedure as found in the construction business, and may limit the field and scope of the operations of a licensed contractor to those in which the licensed contractor is classified and qualified to engage, as defined in § 70106.

(b) A licensee may make application for classification and be classified in more than one (1) classification if the licensee meets the qualifications prescribed by the Board for such additional classification. For qualifying or classifying in additional classifications, the licensee shall pay the appropriate application fee but shall not be required to pay any additional license fee.

(c) This Section shall not prohibit a specialty contractor from taking and executing a contract involving the use of two (2) or more crafts or trades, if the performance of the work in the crafts or trades, other than in which the specialty contractor is licensed, is less than thirty-five percent (35%) and supplemental to the performance of work in the craft for which the specialty contractor is licensed.
