(a) In an eminent domain or inverse condemnation proceeding, notwithstanding the provisions of Sections 814 to 821, inclusive, the following matter is inadmissible as evidence and shall not be taken into account as a basis for an opinion as to the value of property: (1) The price or other terms and circumstances of an acquisition of property or a property interest if the acquisition was for a public use for which the property could have been taken by eminent domain. The price or other terms and circumstances shall not be excluded pursuant to this paragraph if the proceeding relates to the valuation of all or part of a water system as defined in Section 240 of the Public Utilities Code. (2) The price at which an offer or option to purchase or lease the property or property interest being valued or any other property was made, or the price at which the property or interest was optioned, offered, or listed for sale or lease, except that an option, offer, or listing may be introduced by a party as an admission of another party to the proceeding; but nothing in this subdivision permits an admission to be used as direct evidence upon any matter that may be shown only by opinion evidence under Section 813. (3) The value of any property or property interest as assessed for taxation purposes or the amount of taxes which may be due on the property, but nothing in this subdivision prohibits the consideration of actual or estimated taxes for the purpose of determining the reasonable net rental value attributable to the property or property interest being valued. (4) An opinion as to the value of any property or property interest other than that being valued. (5) The influence upon the value of the property or property interest being valued of any noncompensable items of value, damage, or injury. (6) The capitalized value of the income or rental from any property or property interest other than that being valued. (b) In an action other than an eminent domain or inverse condemnation proceeding, the matters listed in subdivision (a) are not admissible as evidence, and may not be taken into account as a basis for an opinion as to the value of property, except to the extent permitted under the rules of law otherwise applicable.
