Health & Saf. Code, § 34281

A commissioner or employee of an authority shall not acquire any direct or indirect interest in any housing project or in any property included or planned to be included in any project, nor shall he have any direct or indirect interest in any contract or proposed contract for materials or services to be furnished or used in connection with any housing project. If he owns or controls a direct or indirect interest in any such property, he shall immediately make a written disclosure of it to the authority and the disclosure shall be entered upon its minutes. Failure so to disclose his interest constitutes misconduct in office.

Nothing contained in this section or in any other provision of law shall be construed as precluding a tenant of an authority from serving as a commissioner of that authority, provided that the fact of such tenancy is disclosed to the authority in writing and entered upon its minutes immediately upon his assuming office; nor shall any provision in this code or elsewhere be construed as in any manner inhibiting the right of such tenant commissioner to exercise the full powers vested in his office.
