For Immediate Release

2019  Flood Information from the Assessors Office

Santa Rosa, CA  –  March 7, 2019  –  Sonoma County Assessor Deva Marie Proto announced today that property owners who have suffered damage to their business property, structures or land over $10,000 due to the 2019 Floods should file a “Calamity Damage Reassessment Form” to provide property tax relief. 

Property owners have 12 months from the event date to file the Calamity Damage Reassessment form. Property owners may want to wait until they have information from insurance providers, or have contractor’s bids for repair work before filing. Reassessments of property will be conducted by the Assessor’s Office and supplemental adjustments will be processed retroactively and sent out to property owners in fall 2019.

It is important for property owners to know that they will still need to pay the 2nd installment of the 2018-19 secured tax bill so as not to incur penalties. The 2nd installment will become delinquent if not paid by 5:00PM on April 10, 2019. Due to annual assessment roll processes mandated by the California Constitution and the Board of Equalization, the Assessor’s Office will begin processing the calamity reassessments in late summer and, if applicable, prorated tax refunds will be issued by the Auditor-Controller-Treasurer-Tax Collector’s Office approximately 30 days after reassessments are completed.

Property owners that have relocated due to the 2019 Floods need to make sure the Sonoma County Assessor’s office has their correct mailing address. The Assessor’s Office is working with Sonoma County Auditor-Controller-Treasurer-Tax Collector, Erick Roeser, to ensure that all property tax mailings are up to date. Ms. Proto asked that all relocated property owners fill out a “Change in Mailing Address” form and return it by mail to the Assessor’s Office.

Assessor Proto asked property owners who are unsure if they have already completed a “Change in Mailing Address” form to call her office at (707) 565-1888 to confirm their updated address.

The Calamity Damage Reassessment Claim form as well as the Change in Mailing Address form can be found here.
