Sonoma, CA Real Estate Market Update: Prices, Inventory, and Trends
By Matthew Martinez, Founder, CEO & Managing Broker, Diamond Real Estate Group. California DRE #01869679.
As of October 2026, the Sonoma market is moving faster than a year ago but isn’t overheated: City of Sonoma homes spent a median of 40 days on the market in the three months ending September, down from 76, and sold at about 98% of list price.
The city’s median sale price was about $1.02 million, down 21% on a small number of sales, while the median price per square foot rose almost 16%. Mortgage rates are above 7%. Here’s the full picture on prices, pace and inventory, and what it means if you’re buying or selling.

Prices: read the median carefully
The City of Sonoma has only about 40 to 50 home sales a month, so the median moves with the mix of homes that sell. Over the latest three months, the median sale price fell 21.2% while the median price per square foot rose 15.7%. That combination means more smaller homes sold, not that the same homes lost a fifth of their value. The county figures are steadier: Redfin’s county median rose 6.6%, and C.A.R.’s single-family median rose 10.1% from September 2025, though C.A.R.’s also jumped 10.8% from August alone, another sign of month-to-month noise.
For a specific home, recent sales of similar homes nearby matter far more than any of these headlines. Our guide to Sonoma vs Sonoma County explains why city and county numbers differ.
Pace: faster than last year
Median days on market fell from 76 to 40 in the city and from 57 to 45 in the county. Sale-to-list ratios rose to 98.3% in the city and 100.3% countywide, and 38.3% of county homes sold above list compared with 19.5% in the city. In short, buyers are more active than a year ago, and the competition is stronger at lower price points than in the higher-priced city. We break this down further in how competitive the Sonoma market is right now.
Inventory
Statewide, C.A.R.’s Unsold Inventory Index was 3.7 months in September 2026, with active listings up 0.5% from a year earlier; in the Bay Area it was 2.6 months (C.A.R.). C.A.R. doesn’t publish an inventory figure for Sonoma County in that report. In the city, the number of homes for sale changes week to week; we track it from the MLS and can tell you how many homes compete with yours in a given price range and area.
Longer-term supply stays tight. The city’s urban growth boundary runs through 2040 (City of Sonoma), and the biggest planned projects nearby, at the Sonoma Developmental Center campus and in the Springs, are still in environmental review (Permit Sonoma).
Rates and insurance
At 7.32%, each $100,000 borrowed costs about $690 a month in principal and interest over 30 years. That keeps payment-sensitive buyers careful and makes seller credits and rate buydowns useful negotiating tools. On insurance, the California Department of Insurance reported in May 2026 that new FAIR Plan residential policies had slowed to about 16,000 in the first quarter, down from 35,000 to 50,000 a quarter in 2024 and most of 2025, as more insurers returned to writing policies (California Department of Insurance). Buyers should still get a quote early in escrow, especially in higher fire zones.

What buyers should do now
Get preapproved at today’s rate, line up an insurance quote, and focus on comparable sales rather than list prices. Homes that have been on the market a while and had a price cut often leave room to negotiate. If you’re new to buying, see our first-time homebuyer’s guide and our guide to buying a home in Sonoma County.
What sellers should do now
Price from today’s competing listings and recent sales, not a past peak. Handle inspections and the defensible-space inspection before listing, fix obvious issues, and be ready to negotiate terms such as credits. Start with a home valuation, and read our guide to selling a home in Sonoma.

Questions people ask
Are Sonoma home prices falling?
The city’s median fell over the latest three months, but price per square foot rose and the county median rose. Prices for comparable homes look closer to flat or up than the headline median suggests.
Is it a buyer’s or seller’s market?
It depends on the home. Well-priced, move-in-ready homes sell quickly; others negotiate.
How often should I check the numbers?
If you’re actively buying or selling, look at the competing listings every week. The monthly statistics are better for spotting trends.
