Section § 170

Explanation

If your property in California gets damaged without your fault, you might get a property tax break through reassessment thanks to a special county law. To qualify, the damage must be from a major disaster, like a state-declared emergency, a regular calamity, or a specific issue with government land access. Apply for the reassessment within the timeframe set by your county, or at most one year after the disaster. This application needs details about your property's condition and its value loss, and it must be done under oath. If the county agrees, your tax can be adjusted based on the reduced property value. You can also appeal the reassessment if you're unhappy with it. Additionally, owners of properties damaged by certain wildfires have up to two years to apply for reassessment.

(a)CA Revenue & Taxation Code § 170(a) Notwithstanding any other law, the board of supervisors, by ordinance, may provide that every assessee of any taxable property, or any person liable for the taxes thereon, whose property was damaged or destroyed without the assessee’s or liable person’s fault, may apply for reassessment of that property as provided in this section. The ordinance may also specify that the assessor shall have the discretion to determine the appropriate date of damage and may initiate the reassessment where the assessor determines that within the preceding 12 months taxable property located in the county was damaged or destroyed.
To be eligible for reassessment the damage or destruction to the property shall have been caused by any of the following:
(1)CA Revenue & Taxation Code § 170(1) A major misfortune or calamity, in an area or region subsequently proclaimed by the Governor to be in a state of disaster, if that property was damaged or destroyed by the major misfortune or calamity that caused the Governor to proclaim the area or region to be in a state of emergency, pursuant to Section 8625 of the Government Code, or a state of disaster. As used in this paragraph, “damage” includes a diminution in the value of property as a result of restricted access to the property where that restricted access was caused by the major misfortune or calamity.
(2)CA Revenue & Taxation Code § 170(2) A misfortune or calamity.
(3)CA Revenue & Taxation Code § 170(3) A misfortune or calamity that, with respect to a possessory interest in land owned by the state or federal government, has caused the permit or other right to enter upon the land to be suspended or restricted. As used in this paragraph, “misfortune or calamity” includes a drought condition such as existed in this state in 1976 and 1977.
The application for reassessment may be filed within the time specified in the ordinance or within 12 months of the misfortune or calamity, whichever is later, by delivering to the assessor a written application requesting reassessment showing the condition and value, if any, of the property immediately after the damage or destruction, and the dollar amount of the damage. The application shall be executed under penalty of perjury, or if executed outside the State of California, verified by affidavit.
An ordinance may be made applicable to a major misfortune or calamity specified in paragraph (1) or to any misfortune or calamity specified in paragraph (2), or to both, as the board of supervisors determines. An ordinance shall not be made applicable to a misfortune or calamity specified in paragraph (3), unless an ordinance making paragraph (2) applicable is operative in the county. The ordinance may specify a period of time within which the ordinance shall be effective, and, if no period of time is specified, it shall remain in effect until repealed.
(b)CA Revenue & Taxation Code § 170(b) Upon receiving a proper application, the assessor shall appraise the property and determine separately the full cash value of land, improvements and personalty immediately before and after the damage or destruction. If the sum of the full cash values of the land, improvements and personalty before the damage or destruction exceeds the sum of the values after the damage by ten thousand dollars ($10,000) or more, the assessor shall also separately determine the percentage reductions in value of land, improvements and personalty due to the damage or destruction. The assessor shall reduce the values appearing on the assessment roll by the percentages of damage or destruction computed pursuant to this subdivision, and the taxes due on the property shall be adjusted as provided in subdivision (e). However, the amount of the reduction shall not exceed the actual loss.
(c)Copy CA Revenue & Taxation Code § 170(c)
(1)Copy CA Revenue & Taxation Code § 170(c)(1) As used in this subdivision, “board” means either the county board of supervisors acting as the county board of equalization, or an assessment appeals board established by the county board of supervisors in accordance with Section 1620, as applicable.
(2)CA Revenue & Taxation Code § 170(c)(2) The assessor shall notify the applicant in writing of the amount of the proposed reassessment. The notice shall state that the applicant may appeal the proposed reassessment to the board within six months of the date of mailing the notice. If an appeal is requested within the six-month period, the board shall hear and decide the matter as if the proposed reassessment had been entered on the roll as an assessment made outside the regular assessment period. The decision of the board regarding the damaged value of the property shall be final, provided that a decision of the board regarding any reassessment made pursuant to this section shall create no presumption as regards the value of the affected property subsequent to the date of the damage.
(3)CA Revenue & Taxation Code § 170(c)(3) Those reassessed values resulting from reductions in full cash value of amounts, as determined above, shall be forwarded to the auditor by the assessor or the clerk of the board, as the case may be. The auditor shall enter the reassessed values on the roll. After being entered on the roll, those reassessed values shall not be subject to review, except by a court of competent jurisdiction.
(d)Copy CA Revenue & Taxation Code § 170(d)
(1)Copy CA Revenue & Taxation Code § 170(d)(1) If no application is made and the assessor determines that within the preceding 12 months a property has suffered damage caused by misfortune or calamity that may qualify the property owner for relief under an ordinance adopted under this section, the assessor shall provide the last known owner of the property with an application for reassessment. The property owner shall file the completed application within 12 months after the occurrence of that damage. Upon receipt of a properly completed, timely filed application, the property shall be reassessed in the same manner as required in subdivision (b).
(2)CA Revenue & Taxation Code § 170(d)(2) This subdivision does not apply where the assessor initiated reassessment as provided in subdivision (a) or (l).
(e)CA Revenue & Taxation Code § 170(e) The tax rate fixed for property on the roll on which the property so reassessed appeared at the time of the misfortune or calamity, shall be applied to the amount of the reassessment as determined in accordance with this section and the assessee shall be liable for: (1) a prorated portion of the taxes that would have been due on the property for the current fiscal year had the misfortune or calamity not occurred, to be determined on the basis of the number of months in the current fiscal year prior to the misfortune or calamity; plus, (2) a proration of the tax due on the property as reassessed in its damaged or destroyed condition, to be determined on the basis of the number of months in the fiscal year after the damage or destruction, including the month in which the damage was incurred. For purposes of applying the preceding calculation in prorating supplemental taxes, the term “fiscal year” means that portion of the tax year used to determine the adjusted amount of taxes due pursuant to subdivision (b) of Section 75.41. If the damage or destruction occurred after January 1 and before the beginning of the next fiscal year, the reassessment shall be utilized to determine the tax liability for the next fiscal year. However, if the property is fully restored during the next fiscal year, taxes due for that year shall be prorated based on the number of months in the year before and after the completion of restoration.
(f)CA Revenue & Taxation Code § 170(f) Any tax paid in excess of the total tax due shall be refunded to the taxpayer pursuant to Chapter 5 (commencing with Section 5096) of Part 9, as an erroneously collected tax or by order of the board of supervisors without the necessity of a claim being filed pursuant to Chapter 5.
(g)CA Revenue & Taxation Code § 170(g) The assessed value of the property in its damaged condition, as determined pursuant to subdivision (b) compounded annually by the inflation factor specified in subdivision (a) of Section 51, shall be the taxable value of the property until it is restored, repaired, reconstructed or other provisions of the law require the establishment of a new base year value.
If partial reconstruction, restoration, or repair has occurred on any subsequent lien date, the taxable value shall be increased by an amount determined by multiplying the difference between its factored base year value immediately before the calamity and its assessed value in its damaged condition by the percentage of the repair, reconstruction, or restoration completed on that lien date.
(h)Copy CA Revenue & Taxation Code § 170(h)
(1)Copy CA Revenue & Taxation Code § 170(h)(1) When the property is fully repaired, restored, or reconstructed, the assessor shall make an additional assessment or assessments in accordance with subparagraph (A) or (B) upon completion of the repair, restoration, or reconstruction:
(A)CA Revenue & Taxation Code § 170(h)(1)(A) If the completion of the repair, restoration, or reconstruction occurs on or after January 1, but on or before May 31, then there shall be two additional assessments. The first additional assessment shall be the difference between the new taxable value as of the date of completion and the taxable value on the current roll. The second additional assessment shall be the difference between the new taxable value as of the date of completion and the taxable value to be enrolled on the roll being prepared.
(B)CA Revenue & Taxation Code § 170(h)(1)(B) If the completion of the repair, restoration, or reconstruction occurs on or after June 1, but before the succeeding January 1, then the additional assessment shall be the difference between the new taxable value as of the date of completion and the taxable value on the current roll.
(2)CA Revenue & Taxation Code § 170(h)(2) On the lien date following completion of the repair, restoration, or reconstruction, the assessor shall enroll the new taxable value of the property as of that lien date.
(3)CA Revenue & Taxation Code § 170(h)(3) For purposes of this subdivision, “new taxable value” shall mean the lesser of the property’s (A) full cash value, or (B) factored base year value or its factored base year value as adjusted pursuant to subdivision (c) of Section 70.
(i)CA Revenue & Taxation Code § 170(i) The assessor may apply Chapter 3.5 (commencing with Section 75) of Part 0.5 in implementing this section, to the extent that chapter is consistent with this section.
(j)CA Revenue & Taxation Code § 170(j) This section applies to all counties, whether operating under a charter or under the general laws of this state.
(k)CA Revenue & Taxation Code § 170(k) Any ordinance in effect pursuant to former Section 155.1, 155.13, or 155.14 shall remain in effect according to its terms as if that ordinance was adopted pursuant to this section, subject to the limitations of subdivision (b).
(l)CA Revenue & Taxation Code § 170(l) When the assessor does not have the general authority pursuant to subdivision (a) to initiate reassessments, if no application is made and the assessor determines that within the preceding 12 months a property has suffered damage caused by misfortune or calamity, that may qualify the property owner for relief under an ordinance adopted under this section, the assessor, with the approval of the board of supervisors, may reassess the particular property for which approval was granted as provided in subdivision (b) and notify the last known owner of the property of the reassessment.
(m)CA Revenue & Taxation Code § 170(m) Notwithstanding subdivision (a), in the case of property damaged or destroyed by the 2025 Palisades Fire, Eaton Fire, Hurst Fire, Lidia Fire, Sunset Fire, or Woodley Fire, or the 2024 Mountain Fire or Franklin Fire, for which the Governor proclaimed a state of emergency, the application for reassessment may be filed within the time specified in the ordinance or within 24 months of the misfortune or calamity, whichever is later.

Section § 170.1

Explanation

This law says that any property within five miles of the Chiquita Canyon Landfill in Los Angeles County must have its value reassessed to reflect any decrease in value due to the landfill's high-temperature event. This new assessment should apply retroactively from January 1, 2022. The property owner will get a notice if there's a change in their property's assessed value, and if they overpaid taxes before, they can apply for a refund.

(a)CA Revenue & Taxation Code § 170.1(a) Notwithstanding any law, as authorized by subdivision (b) of Section 2 of Article XIII A of the California Constitution and paragraph (2) of subdivision (a) of Section 51, each property located within a five-mile radius of the center of the Chiquita Canyon Landfill in the County of Los Angeles shall be reassessed so that the full cash value base of the property reflects any decline in value of the property arising from the Chiquita Canyon elevated temperature landfill event.
(b)CA Revenue & Taxation Code § 170.1(b) Reassessments pursuant to this section shall be retroactive to the January 1, 2022, lien date. Following reassessment, the assessor shall send notice of the assessment value change to the taxpayer. The notice shall state both the amount of the assessment value change and, if property taxes were paid at the higher assessment value, that a refund claim may be filed with the auditor-controller pursuant to Chapter 5 (commencing with Section 5096) of Part 9.
(c)CA Revenue & Taxation Code § 170.1(c) For purposes of this subdivision, “Chiquita Canyon elevated temperature landfill event” means the elevated temperature landfill event that occurred beneath the Chiquita Canyon Landfill in the County of Los Angeles.

Section § 171

Explanation

This law section states that for property taxes from the 1992-93 fiscal year on certain residential properties, no interest or penalties will be charged for late payments. These rules apply to properties affected by the Los Angeles unrest in 1992, where taxes were not delinquent by the end of the 1991-92 fiscal year, and the owner experienced an economic hardship from the unrest. This requires the property to qualify for a homeowner's exemption. Owners claiming 'economic hardship' need to sign a declaration, and the property should be in the Los Angeles Revitalization Zone. Collection actions by the county treasurer or tax collector regarding these taxes were paused until January 1, 1994, after which interest and penalties could apply if taxes remained delinquent. Affected homeowners can seek refunds for any interest or penalties paid on these taxes by filing the appropriate claim forms.

(a)CA Revenue & Taxation Code § 171(a) Notwithstanding any other provision of law, no interest or penalties shall be imposed or collected with respect to any delinquent installments of property taxes levied for the 1992–93 fiscal year on qualified residential real property.
(b)CA Revenue & Taxation Code § 171(b) The county treasurer or tax collector shall not take any collection action, and shall cease any collection action that has commenced, with respect to any delinquent property taxes for the 1992–93 fiscal year that were levied on qualified real property, until on or after January 1, 1994. The treasurer or tax collector may impose any applicable interest and penalties on any delinquent property taxes levied on qualified real property for the 1992–93 fiscal year beginning on or after January 1, 1994, if those taxes or any portion thereof remain delinquent on or after that date.
(c)CA Revenue & Taxation Code § 171(c) For purposes of this section:
(1)CA Revenue & Taxation Code § 171(c)(1) “Qualified residential real property” means any residential real property that meets all of the following conditions:
(A)CA Revenue & Taxation Code § 171(c)(1)(A) No amount of property taxes levied on that property was delinquent at the close of the 1991–92 fiscal year.
(B)CA Revenue & Taxation Code § 171(c)(1)(B) The owner of the property suffered economic hardship as a result of the civil unrest that occurred in Los Angeles in April and May 1992.
(C)CA Revenue & Taxation Code § 171(c)(1)(C) The property is eligible for a homeowner’s exemption.
(2)CA Revenue & Taxation Code § 171(c)(2) An owner shall be deemed to have suffered “economic hardship” if both of the following occur:
(A)CA Revenue & Taxation Code § 171(c)(2)(A) The owner signs a declaration under penalty of perjury under the laws of this state that he or she suffered economic hardship as a result of the civil unrest that occurred in Los Angeles in April and May 1992.
(B)CA Revenue & Taxation Code § 171(c)(2)(B) A business owned by the taxpayer, the taxpayer’s primary place of work, or the taxpayer’s residence that qualifies for the homeowner’s exemption is located in the area designated as the Los Angeles Revitalization Zone pursuant to Government Code Section 7102.
(d)CA Revenue & Taxation Code § 171(d) A claim for relief under this section shall be filed by an owner on a form and in the manner as the treasurer or tax collector shall prescribe.
(e)CA Revenue & Taxation Code § 171(e) The treasurer or tax collector shall permit any individual entitled to relief under this section who has paid any interest or penalties in connection with delinquent taxes levied for the 1992–93 fiscal year on qualified residential real property prior to filing a claim for relief to also file a claim for refund of the interest and penalties paid on a form and in the manner as the treasurer or tax collector shall prescribe.

Section § 171.5

Explanation

This law says that for certain properties damaged in the 2025 Palisades, Eaton, Hurst, Lidia, Sunset, or Woodley fires, the property's full cash value on January 1, 2025, will be based on its market value right before it got damaged or destroyed. This considers any value reduction due to damage, wear and tear, or removal.

The properties in question must have had an emergency declared by the governor due to the fires, and the decrease in value due to damage must be at least $10,000. It's specifically for properties that aren't qualified for other relief programs.

(a)CA Revenue & Taxation Code § 171.5(a) Notwithstanding Section 51, for purposes of determining the full cash value of qualified real property, the fair market value of that qualified real property on January 1, 2025, shall be its full cash value as of the date the property was damaged or destroyed, taking into account reductions in value due to damage, destruction, depreciation, obsolescence, removal of property, or other factors causing a decline in value.
(b)CA Revenue & Taxation Code § 171.5(b) For purposes of this section, “qualified real property” shall mean real property impacted by the 2025 Palisades Fire, Eaton Fire, Hurst Fire, Lidia Fire, Sunset Fire, or Woodley Fire, for which the Governor proclaimed a state of emergency, if the sum of the full cash values of the land, improvements, and personality before the damage or destruction exceeds the sum of the values after the damage by ten thousand dollars ($10,000) or more, and if the property is not eligible for relief under Section 170.
