Sonoma County property owners whose homes suffered more than $10,000 in damage from the October firestorm will begin receiving reassessment notices in the mail over the coming weeks, the county assessor’s office announced Thursday.

Residents will receive notices, which will result in new 2017-2018 tax bills, over a staggered period as the office sends them out in batches. Property owners can choose to pay the first installment of their original tax bill or wait until they get a new one, after which they’ll have at least 30 days to make the initial payment, according to the assessor’s office.

The county says it will also include information about how properties’ assessed values will be prorated to account for the period before the fires and the period afterward.

Anyone with questions should call the assessor’s office at 707-565-1888 or check online at sonomacounty.ca.gov/CRA/Assessor.
