(b) Disclosure is required pursuant to this section only when one of the following conditions is met:
1. (1) The transferor, or the transferor’s agent, has actual knowledge that the property is within a very high fire hazard severity zone.
2. (2) A map that includes the property has been provided to the local agency pursuant to Section 51178, and a notice is posted at the offices of the county recorder, county assessor, and county planning agency that identifies the location of the map and any information regarding changes to the map received by the local agency.
(c) In all transactions that are subject to Section 1103 of the Civil Code, the disclosure required by subdivision (a) of this section shall be provided by either of the following means:
1. (1) The Local Option Real Estate Disclosure Statement as provided in Section 1102.6a of the Civil Code.
2. (2) The Natural Hazard Disclosure Statement as provided in Section 1103.2 of the Civil Code.
(d) If the map or accompanying information is not of sufficient accuracy or scale that a reasonable person can determine if the subject real property is included in a very high fire hazard zone, the transferor shall mark “Yes” on the Natural Hazard Disclosure Statement. The transferor may mark “No” on the Natural Hazard Disclosure Statement if he or she attaches a report prepared pursuant to subdivision (c) of Section 1103.4 of the Civil Code that verifies the property is not in the hazard zone. Nothing in this subdivision is intended to limit or abridge any existing duty of the transferor or the transferor’s agents to exercise reasonable care in making a determination under this subdivision.
(e) Section 1103.13 of the Civil Code shall apply to this section.
(f) The specification of items for disclosure in this section does not limit or abridge any obligation for disclosure created by any other provision of law or that may exist in order to avoid fraud, misrepresentation, or deceit in the transfer transaction.
