Frequently Asked Questions
What is the property tax rate in Sonoma County by city?
Across Sonoma County the ad-valorem property tax rate for most cities runs about 1.1087% to 1.158% of assessed value, with a median near 1.1347% — the 1% Proposition 13 base plus each area's voter-approved debt. It's highest in Cloverdale (1.1905%) and lowest in Bodega Bay (1.0616%), because voter-approved school, city, and special-district bonds differ from area to area.
Why is Sonoma property tax shown by city and not by ZIP code?
Sonoma County's public parcel file publishes each parcel's situs city but not its situs ZIP code, and its mailing ZIP is protected taxpayer information we don't use. So this page keys the typical rate and bill on the situs city — the honest use of the data the county actually publishes. Within a city, rates still vary by Tax Rate Area; use the rate explorer to see your exact TRA or look up your parcel by APN.
Why does the property tax rate differ by city?
The 1% Proposition 13 base is the same everywhere, but each Tax Rate Area adds its own voter-approved bond debt — school districts, the Santa Rosa Junior College District, water and sanitation districts, and city bonds. Cities in areas with more approved bonds have higher total rates. A single city spans several Tax Rate Areas, so the figure shown is typical for the city, not your parcel's exact rate.
Are Mello-Roos and special assessments included in these rates?
No. These are ad-valorem rates only (the 1% base plus voter-approved debt). Mello-Roos / Community Facilities District special taxes, parcel taxes, and fixed direct assessments are billed separately and can add hundreds to a few thousand dollars a year.
Are the typical values single-family only?
The headline typical value and bill are for single-family homes. Where there's enough data, the calculator also shows condos/townhouses and 2–4 unit residential-income properties for your city, using each type's median assessed value from the Sonoma Assessor use code — an existing-owner Proposition 13 figure, not a buyer's price.
