Cal. Code Regs. tit. 18, § 324
(b) Jurisdiction. The board's authority to determine the full value of property or other issues, while limited by the laws of this state and the laws of the United States and usually exercised in response to an application for equalization, is not predicated on the filing of an application nor limited by the applicant's request for relief. When an application for review includes only a portion of an appraisal unit, whether real property, personal property, or both, the board may nevertheless determine the full value, classification, or other facts relating to other portions that have undergone a change in ownership, new construction or a change in value. Additionally, the board shall determine the full value of the entire appraisal unit whenever that is necessary to the determination of the full value of any portion thereof.
The board is not required to choose between the opinions of value promoted by the parties to the appeal, but shall make its own determination of value based upon the evidence properly admitted at the hearing.
An appraisal unit of property is a collection of assets that functions together, and that persons in the marketplace commonly buy and sell as a single unit or that is normally valued in the marketplace separately from other property, or that is specifically designated as such by law.
(d) Comparable Sales. When valuing a property by a comparison with sales of other properties, the board may consider those sales that, in its judgment, involve properties similar in size, quality, age, condition, utility, amenities, site location, legally permitted use, or other physical attributes to the property being valued. When valuing property for purposes of either the regular roll or the supplemental roll, the board shall not consider a sale if it occurred more than 90 days after the date for which value is being estimated. The provisions for exclusion of any sale occurring more than 90 days after the valuation date do not apply to the sale of the subject property.
The board shall presume that zoning or other legal restrictions, of the types described in Revenue and Taxation Code section 402.1, on the use of either the property sold or the property being valued will not be removed or substantially modified in the predictable future unless sufficient grounds as set forth in that section are presented to the board to overcome that presumption.
