(a) Except as provided for in subdivision (b), every household mover, as a condition precedent to the issuance, reinstatement, reactivation, renewal, or continued maintenance of a permit, shall have on file with the bureau a current and valid Certificate of Workers’ Compensation Insurance or Certification of Self-Insurance in the applicant’s or permitholder’s business name. A Certificate of Workers’ Compensation Insurance shall be issued and filed, electronically or otherwise, by an insurer duly licensed to write workers’ compensation insurance in this state. If reciprocity conditions exist, as provided in Section 3600.5 of the Labor Code, the bureau shall require the information deemed necessary to ensure compliance with this section.
(b) This section does not apply to an applicant or permitholder who has no employees, provided that the applicant or permitholder files a statement, under penalty of perjury, stating that, in its operations as a household mover, it does not employ any person in any manner so as to become subject to the workers’ compensation laws of this state.
(c) The workers’ compensation coverage certified to under subdivision (a) shall be effective until canceled. Cancellation shall require 30 days’ advance notice. A workers’ compensation insurer shall also report to the bureau a permitholder whose workers’ compensation insurance policy is canceled by the insurer if all of the following conditions are met:
1. (1) The insurer has completed a premium audit or investigation.
2. (2) A material misrepresentation has been made by the insured that results in financial harm to the insurer.
3. (3) No reimbursement has been paid by the insured to the insurer.
(d) If, after filing the statement described in subdivision (b), the household mover becomes subject to the workers’ compensation laws of this state, the household mover shall promptly notify the bureau that the household mover is withdrawing its statement under subdivision (b), and shall simultaneously file the certificate described in subdivision (a).
(e) The insurer, including the State Compensation Insurance Fund, shall report to the bureau the following information for any policy required under this section: name, license number, policy number, and dates that coverage is scheduled to commence and lapse, and cancellation date, if applicable.
