California Code, Health and Safety Code - HSC § 18933

(a) The commission may give affected state agencies reasonable time, as specified by the commission, to adopt amendments to building standards submitted for approval. If the agencies do not do so within the reasonable time as specified, the commission shall convene a committee composed of a representative from each of the agencies affected and any other qualified persons who are selected by the commission. This committee shall prepare a recommendation for commission action upon the building standards. Upon the recommendation, or if the committee does not prepare a recommendation and deliver it to the commission within 30 days after being appointed, the commission may rewrite, edit, amend, or adopt, and approve the building standards consistent with the intent of this part and in accordance with the Administrative Procedure Act and the criteria for approval provided in Section 18930. It shall not, however, be required that hearings or other administrative procedure be duplicated on unchanged portions of building standards previously adopted and approved by the commission.
