Cal. Business and Professions Code § 7187

When a building owner or operator contracts with an asbestos consultant or site surveillance technician for performance of the activities described in Sections 7181 and 7182, that asbestos consultant or site surveillance technician shall not have any financial or proprietary interest in an asbestos abatement contractor hired for the same project. However, this section shall not preclude the hiring of a consultant by a contractor for the purpose of providing health and safety services for the personnel of the contractor. This section shall not apply when a licensed contractor or registered asbestos abatement contractor takes no more than 12 bulk samples of suspected asbestos-containing material that is required to be removed, repaired, or disturbed as part of a construction project in a residential dwelling solely for any of the following purposes: (1) bid preparation for asbestos abatement; (2) evaluating exposure to its own employees during construction or asbestos abatement; or (3) determining for its own purposes or for the purpose of communicating whether or not a contract for asbestos abatement has been satisfactorily completed. Persons taking samples for the purposes described in this section shall be certified building inspectors under the Asbestos Hazard Emergency Response Act, as specified in Section 763 of Title 40 of the Code of Federal Regulations, appendix (c) to subpart (e). No licensed contractor or asbestos abatement contractor may provide professional health and safety services or perform any asbestos risk assessment. A licensed contractor or asbestos abatement contractor may seek compensation for bid preparation, including the cost of laboratory analysis of asbestos-containing material. It is the intent of the Legislature in enacting this section to make certain that the asbestos-related work performed by a consultant, including, but not limited to, clearance air monitoring, project design, and contract administration, is performed in a manner which provides for independent professional judgment undertaken without consideration of the financial or beneficial interest of the contractor.
