(2) Upon identification by the Director of Forestry and Fire Protection pursuant to Section 51178 of the Government Code of high fire hazard severity zones and by a local agency pursuant to Section 51179 of the Government Code, the Office of the State Fire Marshal and the Department of Housing and Community Development shall propose, and the California Building Standards Commission shall adopt, expanded application of the building standards adopted pursuant to this section to high fire hazard severity zones during the next triennially occurring code adoption cycle.

(3) The State Fire Marshal and the Department of Housing and Community Development shall, after consulting with interested stakeholders, including local fire officials, consider if it is appropriate to expand application of the building standards adopted pursuant to this section to moderate fire hazard severity zones.
