September 2026 Northern California Housing Market: Why Location Changes Everything

Eight months of inventory in Napa County. Just 1.3 months in San Francisco. Same region, two very different housing markets.

Is Northern California currently a buyer's market or a seller's market?

September's real estate numbers offer an interesting answer: it depends on where you're looking.

In Napa County, buyers have more homes to choose from and potentially more time to negotiate. Meanwhile, San Francisco's single-family home market continues to show strong competition, with limited inventory and homes selling well above their original asking prices on average.

And between those two markets? Counties like Sonoma, Marin, Solano and Contra Costa, each with its own combination of inventory, pricing and buyer demand.

Our September 2026 Northern California Housing Market Report examines nine counties to help buyers, sellers and homeowners understand what these numbers mean beyond the headlines.

Napa County: More Inventory Is Changing the Conversation

Napa County stands out in September's report.

Single-family homes recorded:

• Median sold price: $880,000
• Months of inventory: 8.0
• Average days on market: 63
• Sold-to-original-list-price ratio: 94%

Eight months of inventory means that, at the current sales pace, the available supply represents approximately eight months of homes.

For buyers searching in Napa, American Canyon, Yountville, St. Helena or Calistoga, that may create opportunities to compare properties, evaluate asking prices and negotiate based on individual circumstances.

But greater inventory doesn't mean every home is negotiable.

Well-priced properties in desirable locations can still attract serious interest. The difference is that buyers may have more alternatives when a property doesn't meet their expectations.

What does this mean for Napa homeowners thinking about selling?

When inventory is elevated, the first few weeks on the market become especially important.

Buyers are comparing homes online, visiting open houses and watching which properties sell versus which remain available.

A home that enters the market with an unrealistic asking price may struggle to attract the right attention.

September's 94% sold-to-original-list-price ratio suggests that initial pricing deserves careful consideration. This countywide statistic does not mean every Napa seller accepted 6% below their asking price.

For homeowners, the opportunity lies in understanding the competition before listing.

The goal is to price and prepare your home for the market you're entering, not the market you remember.

San Francisco: Single-Family Homes Remain Competitive

San Francisco's single-family housing market tells a very different story.

September's numbers included:

• Median sold price: $2,054,000
• Months of inventory: 1.3
• Average days on market: 21
• Sold-to-original-list-price ratio: 128%

With only 1.3 months of inventory, buyers have a relatively limited selection of available single-family homes.

And with an average market time of just 21 days, desirable properties may not remain available for long.

For buyers, this reinforces the value of preparation. Understanding financing, reviewing recent comparable sales and discussing offer strategies before finding the right property can make the process less stressful.

For sellers, limited inventory may support strong interest, but that doesn't mean every property will achieve the same result.

Neighborhood, condition, presentation, price point and marketing all influence how buyers respond.

What about San Francisco condos and townhomes?

This is where looking beyond the single-family numbers becomes especially important.

San Francisco condos recorded:

• Median sold price: $1,300,000
• Months of inventory: 2.2
• Average days on market: 35
• Sold-to-original-list-price ratio: 111%

Townhomes recorded a $1.4 million median sold price, 1.5 months of inventory and an average market time of 30 days.

However, only four townhome sales were included in the report, so those figures should be interpreted cautiously.

The takeaway?

Buying a condo in San Francisco may involve different market conditions than buying a single-family home—even within the same neighborhood.

That's why property type matters just as much as location.

Marin County: Buyers Are Still Competing for Limited Inventory

Marin County also showed relatively tight single-family inventory in September.

The numbers included:

• Median sold price: $1,679,000
• Months of inventory: 1.8
• Average days on market: 33
• Sold-to-original-list-price ratio: 103%

For buyers exploring San Rafael, Novato, Mill Valley, Larkspur and other Marin communities, these figures suggest that competition remains a consideration.

Homes sold for an average of 103% of their original list price, indicating that the market continued to support prices above initial asking levels on average.

For sellers, that can be encouraging.

But buyers are still making decisions based on condition, location and value. Strong market statistics don't eliminate the need for thoughtful preparation and pricing.

Alameda County: Limited Supply Continues to Influence Prices

Alameda County recorded 1.7 months of single-family inventory and an average market time of 24 days.

The median sold price was $1,250,000, and homes sold for an average of 108% of original list price.

These numbers suggest that competition remained relatively strong across the county.

However, the experience of buying a home in Oakland, Berkeley, Alameda, Castro Valley or Pleasanton can vary considerably.

Countywide statistics combine different neighborhoods, price points and property conditions.

For buyers, reviewing recent comparable sales can help establish realistic expectations.

For sellers, understanding the specific competition around their property is more useful than relying on a single countywide figure.

Sonoma County: Pricing and Preparation Matter

Sonoma County recorded:

• Median sold price: $870,000
• Months of inventory: 3.1
• Average days on market: 57
• Sold-to-original-list-price ratio: 96%

Sonoma sits between the higher-inventory Napa market and the more competitive conditions seen in Marin and San Francisco.

For buyers looking in Santa Rosa, Petaluma, Sonoma, Sebastopol or Rohnert Park, individual property circumstances may create opportunities to negotiate.

For sellers, September's numbers reinforce the importance of understanding what buyers are choosing.

A home that is well prepared and priced appropriately for its location may have a better chance of attracting serious interest.

Solano County: Buyers Have Choices, but Local Conditions Matter

Solano County's September single-family housing statistics included:

• Median sold price: $580,000
• Months of inventory: 3.0
• Average days on market: 51
• Sold-to-original-list-price ratio: 97%

For buyers considering Fairfield, Vacaville, Vallejo, Benicia or Suisun City, these figures provide useful context.

However, a home in downtown Benicia may appeal to a different buyer than a newer property in Vacaville.

For sellers, the most useful comparison isn't necessarily the entire county. It's the homes competing for the same buyers in a similar price range.

Contra Costa County: Homes Are Selling Near Original Asking Prices

Contra Costa County recorded a median single-family sold price of $859,000.

Inventory measured 2.2 months, while homes averaged 31 days on market and sold for an average of 100% of their original list price.

That relationship between asking and selling prices suggests that initial pricing remained an important part of the market.

Buyers searching in Walnut Creek, Concord, Lafayette, Brentwood and surrounding communities should still evaluate individual listings carefully.

For sellers, preparation, presentation and a pricing strategy supported by comparable sales remain important.

Sacramento and Yolo Counties: Different Price Points, Similar Considerations

Sacramento and Yolo counties offer another perspective on Northern California housing conditions.

Sacramento County recorded a median single-family sold price of $555,000, 2.6 months of inventory and an average market time of 35 days. Homes sold for an average of 98% of original list price.

Yolo County recorded a median sold price of $635,000, 2.8 months of inventory and an average market time of 32 days. Homes averaged 95% of original list price.

While the median prices differ, both counties illustrate the importance of looking at local inventory and comparable sales when making real estate decisions.

What September's Housing Market Means for Buyers

If you're planning to buy a home in Northern California, start by understanding the conditions in the neighborhoods you're considering.

More inventory may mean greater choice and potentially more negotiating opportunities.

In markets with limited inventory, preparation becomes particularly valuable.

Before making an offer, consider how long the property has been listed, how its price compares with recent sales and whether competing homes offer similar value.

A good buying strategy isn't about moving quickly on every home.

It's about knowing when to act and when to take more time.

What September's Housing Market Means for Sellers

For homeowners considering selling, September's report offers an important reminder.

Your home's value isn't determined by a national headline or even a countywide median.

It's influenced by what buyers are willing to pay for comparable properties in your neighborhood.

Napa's 8 months of inventory and San Francisco's 1.3 months illustrate how dramatically the selling experience can differ within Northern California.

Understanding active competition, recent sales, property condition and buyer expectations can help you make better decisions about timing, preparation and pricing.

Your Neighborhood Tells a More Personal Story

Market reports are valuable because they help us understand broader trends.

But real estate decisions happen one home at a time.

A downtown Napa bungalow doesn't compete with the same properties as a vineyard estate in St. Helena.

A San Francisco condo doesn't necessarily follow the same market patterns as a single-family home.

And a house in Walnut Creek may attract different buyers than one in Brentwood.

That's why we encourage homeowners and buyers to look beyond countywide averages.

At EO&A, we help clients understand the numbers that matter to their specific property and goals.
