The Sonoma County housing market is firmly in seller’s market territory. With only 2.9 months of inventory, down 34.5% from a year ago, and homes closing at a median of 100.5% of their asking price, the county-wide picture is one of compressed supply and persistent buyer demand. The median sold price reached $875,000 in May 2026, up 2.53% from April, with the average home spending just 30 days on the market before going under contract.
Compare that to the broader California market: Sonoma County’s velocity and above-ask closing ratio reflect a supply-demand imbalance that continues to reward sellers who price correctly and buyers who move decisively.
Two numbers define this market heading into summer: 477 new pending contracts signed in May (up 38.3% from April), and only 2.9 months of available supply. Demand is outrunning inventory, and there is no current data to suggest that reverses soon.

What Are the Current Average Home Prices in the Sonoma County Housing Market?
The median sold price for single-family homes in Sonoma County in May 2026 was $875,000, based on 337 MLS-recorded closed transactions. Sellers received 100.51% of their asking price on average, meaning the typical home sold above list.
| Segment | Median Price | # of Properties | Median $/Sqft |
|---|---|---|---|
| Active Listings | $1,150,000 | 947 | $607 |
| New Listings (May) | $879,000 | 503 | $539 |
| New Pending | $860,000 | 477 | $513 |
| Pending (all) | $850,000 | 286 | $498 |
| Sold (MLS) | $875,000 | 337 | $530 |
| Sold (Public Records) | $872,500 | 228 | $526 |
| Median Estimated Value | $792,640 | — | — |
Unlike Healdsburg, where a large gap separates listed from closed prices, Sonoma County shows remarkable alignment between what sellers ask and what buyers pay. The $875K median close versus $879K new listing median confirms that the market is pricing accurately and buyers are accepting those prices, often exceeding them.
The median estimated property value of $792,640, up 0.6% month-over-month but down 1.4% year-over-year, reflects a modest, ongoing correction in estimated values that is not yet visible in transaction prices. This divergence between estimated and transacted values is a feature of seller’s markets: active buyers absorb available inventory at or above the asking price, while the broader estimated-value base adjusts more slowly.
Sonoma County Average Home Price Trends
A Seller’s Market Holding Steady Near Peak Velocity
Sonoma County single-family prices climbed steadily from 2012 through a peak in 2022, tracking closely with California’s statewide appreciation curve but consistently trading at a premium. The current median sold price of $875K reflects a market that has softened modestly from its 2022 highs without giving back the structural gains built over a decade of undersupply.
Key trend data from the current report:
- New listings came to market at a median of $879K in May, down 7.5% from April, with fewer and cheaper new entries, keeping available-to-buyer selection tight
- Active inventory stands at just 947 properties across the entire county with a total listed value of $1.8B; the median active list price is $1.15M, up 2.2% MoM, reflecting the composition of unsold higher-end stock
- Months of supply at 2.9 is 6.8% below April and 34.5% below May 2025, this is the single most important number in the report. At 2.9 months, Sonoma County is comfortably in seller’s market territory (anything under 4–5 months favors sellers)
- Sold volume totaled $378.8M across 337 MLS transactions, a substantial, healthy market at scale

Price Per Square Foot
MLS-recorded sold homes closed at $530/sqft in May, essentially flat from the prior month (-1.5%). Public records data corroborates with $526/sqft across 228 transactions. Active listings are priced at $607/sqft, and new listings came to market at $539/sqft, the tightest spread between new list $/sqft and closed $/sqft seen in recent months, reinforcing that sellers and buyers are aligned on value.
Market Type: Seller’s Market
The RPR market type indicator places Sonoma County single-family firmly in seller’s market territory with 2.9 months of supply. Homes are selling in 30 days at 100.5% of asking, metrics that should inform every buyer’s strategy and every seller’s pricing conversation.
Inventory and Supply: The Core Constraint
Active single-family inventory across Sonoma County is 947 properties, down 4.1% from April, with a median of 45 days on market (up 25% MoM, but still fast). Total active value is $1.8B.
The more telling numbers are in pending activity. 477 homes went under contract in May, up 38.3% from April, at a median pending price of $860K and a total pending volume of $537.2M, up 45.1% MoM. This surge in pending activity, against a backdrop of shrinking active inventory, is what drives the under-3-month supply figure.
Pending-to-active ratio: 477 new pendings vs. 947 active listings = roughly 50%. One in every two listed homes found a buyer in May. That is not a balanced market.
The year-over-year inventory decline of 34.5% means this supply constraint is not a temporary blip, it reflects a structural reduction in available homes that has been building over the past 12 months. Until new listing volume increases meaningfully above the current 503/month pace, the supply-demand gap will remain tilted toward sellers.
What This Market Means for Buyers
The Sonoma County data from the Realtors Property Resource (RPR) is direct: this is a seller’s market, and buyers need to approach it as one.
- 100.5% sold-to-list ratio means expecting to negotiate below asking is not a default strategy; many homes are fielding multiple offers
- 30-day median time on market leaves little room for extended due diligence before another buyer moves
- 477 new pendings in May (up 38.3% MoM) confirm that competition is real and active — not theoretical
- 2.9 months of supply means roughly 1 in every 2 homes listed is going under contract in a given month
- The $860K median pending price is only 1.7% below the median active list price, but buyers are not finding significant discounts
The practical implication: buyers should have financing locked before touring, know their ceiling before making an offer, and not expect extended counter-offer cycles on well-priced homes.

What This Market Means for Sellers
Sonoma County sellers are in a favorable position heading into summer 2026, but the data comes with a nuance worth noting:
- The 100.5% sold-to-list ratio means correctly priced homes are not just selling, they’re generating competition that pushes final prices above ask
- 30 days on the market is the median for homes that sold; this figure rewards accurate pricing on day one. Overpriced listings are skewing the upper end of days-on-market data and sitting
- New listing volume dropped 12.8% month-over-month (503 properties in May vs. a higher prior month). Fewer competitors coming to market means now is a good window to list
- Active inventory is down 4.1% MoM and 34.5% YoY, with reduced competition and persistent buyer demand
The sellers who will capture above-ask prices in June 2026 are those who list at fair market value, not above it. The 100.5% ratio reflects homes priced correctly; it does not mean that any price will attract multiple offers.
