(a) The registered interior designer shall attempt to avoid all conflicts of interest with a client or employer. If a conflict of interest is unavoidable, the registered interior designer shall immediately inform the client or employer of any business association, interest, or circumstance which may influence the professional judgment, decisions, practices, or quality of services provided by the registered interior designer.
(b) The registered interior designer may not solicit or accept any gratuity, material favor, or benefit of any substantial nature from any party, agent, servant, or employee who is not a client or employer in connection with any project for which the registered interior designer is performing, or has contracted to perform, interior design services. This solicitation or acceptance includes, but is not limited to, any act, article, money, or other item which is of such value in proportion to the interior design services that its acceptance creates a clandestine obligation on the part of the registered interior designer or otherwise compromises the ability of the registered interior designer to exercise independent judgment.
(c) Notwithstanding subsection (b), a registered interior designer may receive a fee or commission for the sale or the supervision of installation of personal property or fixtures, but may not receive both a fee and a commission without the express consent of the client.
