As of Monday, April 29, the Office of the Assessor-Recorder has a new main office phone number, 628-652-8100. For the 12 months following this transition, constituents who call the Office’s prior phone number will automatically be transferred to our new line. As part of this transition, the Office is instituting key upgrades to improve the experience that San Franciscans have when calling us. To learn more, click here.

The transfer of a principal residence between grandparent and grandchild may be excluded from reassessment if the fair market value of the family home on the date of transfer is less than the sum of the factored base year value plus $1 million. If the fair market value of the family home on the date of transfer exceeds the sum of the factored base year value plus $1 million, the amount in excess of this sum will be added to the factored base year value.

The parents of the grandchild(ren) who qualify as child(ren) of the grandparent(s) must be deceased as of the date of the transfer.

Submission Deadline: The Claim for Reassessment Exclusion for Transfer Between Grandparent and Grandchild Occurring on or After February 16, 2021 form must be filed either within three years of the purchase or transfer of the property, or prior to the subsequent transfer of the property to a third party, whichever is earlier. If the claim form has not been filed by the date specified in the preceding sentence, it will be timely if filed within six months after the date of mailing of the notice of supplemental or escape assessment for the property. If a claim is not timely filed, the exclusion will be granted beginning with the calendar year in which the claim is filed.

Additionally, the transferee must file a Claim for Homeowners’ Property Tax Exemption (BOE‐266) or Claim for Disabled Veterans Property Tax Exemption (BOE‐261‐G) within one year from the date of purchase or transfer.

Note: In November 2020, California voters passed Proposition 19, which makes changes to property tax benefits for families (effective February 16, 2021). Please visit the Proposition 19 resource page for more information.

For transfers that occurred prior to February 16, 2021, please use the Claim for Reassessment Exclusion for Transfer From Grandparent to Grandchild form (BOE‐58‐G).
