(a) MINIMUM CONTENTS OF "MACHINE-PREPARED" OR "ELECTRONIC" LOCAL ROLLS. "Machine-prepared" roll within the meaning of Revenue and Taxation Code Section 109.5 includes any preparation of the local roll by the assessor of each county by an electronic medium. In accordance with Revenue and Taxation Code Section 601 et seq., each local assessment roll shall contain, at a minimum, the following information:

(3) An explanation of abbreviations and legends appearing on the roll.

(4) On the secured roll, the assessor's parcel number or other legal description that identifies each parcel of taxable land, each parcel for which an exemption is enrolled, and each taxable possessory interest in tax-exempt real estate to which the exemption authorized by Section 218 of the Revenue and Taxation Code has been applied. The assessment of the taxable possessory interest shall not be a lien on the tax-exempt real estate and that fact shall be noted on the secured roll.

(5) On the unsecured portion of the roll, the assessor's parcel number or other legal description that sufficiently identifies the location of each taxable possessory interest, improvement, and personal property.

(8) The separately stated assessed values of all land, improvements, and personal property subject to taxation at general property tax rates (or payments in lieu of property tax computed by applying general property tax rates to fixed or variable "assessed values"), and the separately assessed values of any privately owned land, improvements, and personal property of a type that is exempt from taxation, but is subject to ad valorem special assessments when within a district levying such assessments. If real property is situated within a resource conservation district that is levying a special assessment, the assessed value of mineral rights must be separated from the land value.

(13) The total net taxable value.

(14) In a separate section of the roll, the assessed value of any personal property for which tax revenues are subject to allocation in a manner different from that provided for general property tax revenues (e.g. general aircraft).

(15) On the secured roll, a cross-reference notation made pursuant to Revenue and Taxation Code section 2190.2 that is adjacent to the assessment of any taxable land when a possessory interest in such land or an improvement thereon is separately assessed to another owner pursuant to section 2188.2 of the Revenue and Taxation Code.

(16) Whenever the assessor determines that a change in ownership or the completion of new construction has occurred, the assessor shall place a notice of the pending supplemental billing on the roll being prepared and shall notify the auditor, who shall place a notation on the current roll or on a separate document accompanying the current roll that a supplemental billing may be forthcoming.

(17) After each assessment of tax-defaulted property, the assessor shall enter on the roll the fact that it is tax-defaulted and the date of declaration of the default.

(18) Any other items required by the State Board of Equalization for the purpose of identification and valuation of all locally assessed property and the collection of property taxes thereon.

(b) EXEMPT VALUES NOT REQUIRED TO BE ENROLLED. Parcel numbers or other legal descriptions of exempt real property may be entered on the roll without values. Alternatively, such exempt real property may be listed with values shown in a separate column or field (e.g., a comments field) or in the exemption column or field on lines that are coded in such manner as to preclude the addition of the values when the exemption column or field is totaled; the exempt values shall not be shown in land or improvement columns or fields.
