The median property tax rate of 0.69% matches the state figure of 0.69% and is below the national 0.74%. Because the rate is typical, the differences in what owners pay come mostly from the high home values.

Median household income is $99,350, higher than $78,109.75 in California and $65,108 nationally. The unemployment rate is 3%, lower than the state's 3.72% and slightly above the national 2.87%.

Renters live in 33.51% of occupied housing, almost identical to the state's 33.49% and far above the national 21.81%. About a third of households rent.

In short, Sonoma County pairs strong incomes and low unemployment with expensive homes and rents, an average tax rate and a renter share in line with the rest of California. For households, the practical takeaway is that housing consumes a large part of the budget even with healthy incomes. Buyers and researchers can use property records, assessments and recent sales to understand how an individual parcel compares with these county-wide figures.

Assignment and release records follow a mortgage after it is recorded. An assignment shows that a loan was transferred from one lender or holder to another, and a release shows that the loan was paid off and the lien removed from the property.

Sonoma County has 525,713 assignment and release records available for research. They include 65,003 assignment documents, recorded from December 29, 2003, through September 3, 2025, and 460,249 release documents, recorded from March 8, 1999, through September 3, 2025, along with 461 other documents.

These records help show who currently holds a mortgage and whether earlier loans were cleared. Buyers, owners and researchers can use them to confirm that past mortgages were released, follow a loan as it moved between lenders, and spot liens that may still be open before a sale or refinance. The date ranges also make it easier to focus on a particular period in a property's history.
