As of August 2026, Contra Costa County remains a seller-favorable market. Inventory sits at just 2.1 months of supply, homes are selling at or near full list price, and East County medians range from $545,000 to $760,000 depending on city. Conditions favor listing now, though your specific outcome depends on pricing, condition, and timing.
Yes, as of August 2026, Contra Costa County still leans seller-favorable. Inventory sits at 2.1 months of supply countywide, homes are selling at 100% of original list price on average, and East County cities like Brentwood, Oakley, and Antioch are posting median sale prices well above pre-pandemic norms. It is not the frenzied 2021 market, but the fundamentals still favor a prepared seller over a waiting one.
What the Numbers Actually Say Right Now
- I get this question from homeowners constantly: "Has the window closed?" The short answer is no. The longer answer is in the data.
A July 2026 Bay Area market update reports 995 new single-family listings in Contra Costa County against only 662 sales that month. That gap sounds like buyer leverage, but the resulting inventory is just 2.1 months of supply. A balanced market sits around six months. At 2.1 months, sellers still hold meaningful negotiating power.
The same report shows a countywide median sold price of $875,000, average days on market of 27, and a sale-to-original-list-price ratio of 100%. Homes are not flying off the shelf in 48 hours the way they did in 2021, but they are selling at asking price, and that matters enormously to your net.
For historical context, a Contra Costa market archive shows that during an earlier tighter period, the county had only about 50 days of inventory versus a 180-day standard for a balanced market. Even with today's slightly looser conditions, the county is nowhere near buyer territory.
On the listing-price side, the Federal Reserve's FRED housing data pegs the median listing price in Contra Costa County at $774,713 for July 2026. That is the ask. The fact that homes are closing at or above that figure tells you demand is real, not aspirational.
East County Specifics
East County tells a slightly different story than the countywide numbers, and that difference matters if you own in Brentwood, Oakley, Antioch, or Pittsburg.
Recent Zillow market data (trailing approximately 90 days, as of August 2026) shows Brentwood's median sale price at $760,000 with a median of 46 days on market. That is slower than the countywide average of 27 days, which reflects East County's position as the more affordable, higher-inventory end of the county. But 46 days is still well within normal selling range, and 174 active listings with 61 new listings in the last 30 days tells me the pipeline is moving, not stalling.
Here is how the other East County cities stack up, using the same Zillow trailing data:
| Area | Median Sale Price | Median Days on Market | Discovery Bay | $750,000 |
|---|---|---|---|---|
| 39 | Antioch | $575,000 | 41 | Oakley |
| $685,750 | 17 | Pittsburg | $545,000 | 49 |
Oakley stands out at just 17 median days on market, which is exceptionally fast for any market. Pittsburg and Brentwood are moving more slowly, but both are still well under the 90-day threshold that would signal real softness. These are area-level medians. Your home's actual value depends on condition, street, build year, and how it is priced relative to current competition.
For additional context on how East County price points compare to central Contra Costa, a 2026 East County housing analysis ranks dollar-per-square-foot from lowest to highest as Oakley/Brentwood, then Antioch, then Pittsburg, then Concord. East County's relative affordability within the county is a feature for sellers, not a liability. It is exactly what draws buyers who are priced out of Walnut Creek and Concord.
If you want to understand why buyers make that trade-off, I walk through it in detail in Walnut Creek vs. Brentwood: Why Some Buyers Look East. The short version: newer housing stock, larger lots, and a lower entry price point are powerful draws, and they work in your favor as a seller.
What These Numbers Mean for Your Decision
Two things stand out to me when I look at this data together.
First, the sale-to-list ratio at 100% countywide is not a coincidence. It means sellers who price correctly are not leaving money on the table through reductions. Overpriced listings are sitting. Well-priced listings are closing at ask. That dynamic rewards preparation and honest pricing, and it punishes the "let's test the market high" strategy that sometimes worked in 2021.
Second, the FRED median days-on-market data for Contra Costa showed 37 to 40 days in mid-2025. The July 2026 countywide average of 27 days suggests the market has actually tightened slightly on that metric year-over-year, even as inventory has grown modestly. That is not the trajectory of a market rolling over.
Your specific outcome, though, depends on factors the county median cannot capture: your home's condition, your street, your school district, your HOA situation if applicable, and how aggressively you prepare and price. That is where a local market analysis earns its keep.
What Could Change the Calculus
I want to be straight with you here, because I think sellers deserve honesty more than they deserve cheerleading.
The 2.1-month inventory figure is still tight, but it is not as tight as it was during the 2020-2022 run. Mortgage rates remain a real friction point for buyers, which limits the pool of qualified offers compared to a lower-rate environment. And East County's longer days on market relative to the countywide average means you should plan for a realistic timeline, not a weekend bidding war.
The factors that could shift conditions toward buyers: a meaningful rate drop that pulls more inventory to market as move-up sellers finally list, or a broader economic slowdown that softens demand. Neither is happening as of this writing, but they are worth watching if you are considering a 6-to-12-month delay.
Here is the honest framing I give every seller who asks me whether to wait: waiting for a "better" market means betting that rates drop, demand holds, and inventory does not surge. That is a three-variable bet. The market in front of you today is known. The one in six months is not.

- Selling in Contra Costa: What to Factor In Beyond the Data
Market timing is only one piece of the sell-now-or-wait decision. The other pieces are preparation time and seller obligations.
California sellers are required to complete a Transfer Disclosure Statement and other mandated disclosures, including a natural hazard disclosure and lead-based paint disclosure for homes built before 1978. These are standardized statewide forms governed by California law and the California Association of REALTORS. They do not need to be a reason to delay, but they do take time to compile correctly. Factor two to four weeks of preparation into your timeline before you are ready to list.
On the cost side, Contra Costa sellers should know that a documentary transfer tax applies to the sale under California Revenue and Taxation Code Section 11911, with incorporated cities potentially adding a local component. How that cost is allocated between buyer and seller is negotiable in the purchase contract. The Contra Costa County Recorder's Office is the authoritative source for current rates and city-specific add-ons. We always recommend confirming these figures directly rather than relying on portal summaries, which sometimes conflict.
Broker compensation is fully negotiable and not set by law. There is no standard or customary rate. The listing fee is agreed between you and your agent in the listing agreement, and any compensation you choose to offer a buyer's agent is a separate, optional decision. If you want to know what makes sense for your situation, that is a conversation to have directly, not something to benchmark from a blog.
Every situation is different, and the only way to know your actual net is to run the numbers with someone who knows this market and your specific property. That is exactly what a no-obligation consultation is for.
Frequently Asked Questions
Is Contra Costa County still a seller's market in 2026, or has it shifted toward buyers?
It is still a seller's market as of August 2026. Inventory sits at 2.1 months of supply countywide, well below the six months that defines a balanced market, according to a July 2026 Bay Area market update. Homes are selling at 100% of original list price on average, which confirms buyers are not gaining significant negotiating leverage yet.
How long are homes taking to sell in East Contra Costa right now?
It depends on the city. Recent Zillow market data (trailing approximately 90 days, as of August 2026) shows Oakley at a median of 17 days, Discovery Bay at 39, Antioch at 41, Brentwood at 46, and Pittsburg at 49. These are area-level medians, and individual homes can move faster or slower depending on pricing and condition.
What do current months of supply in Contra Costa County mean for my chances of selling quickly?
At 2.1 months of supply, the county is firmly in seller's market territory. A balanced market typically requires around six months of supply. The low inventory means fewer competing listings and more buyer competition for available homes, which generally supports faster sales and stronger pricing for well-prepared sellers.
Are buyers still paying over asking price in Contra Costa County this summer?
The countywide sale-to-original-list-price ratio is at 100% as of July 2026, per a Bay Area market update. That means the average home is selling right at asking price, not dramatically over. Some well-priced, well-prepared homes in high-demand areas attract multiple offers and close above list, but the days of routine 5-10% overbids are not the norm across the county right now.
Should I list my Brentwood or Oakley home now, or wait until inventory is lower?
The data available as of August 2026 does not suggest waiting improves your position. Inventory is already low at 2.1 months countywide, and Oakley in particular is moving at a median of just 17 days. The risk in waiting is that rate changes or economic shifts could alter demand in either direction. Your best move is to get a current market analysis on your specific property and make the decision from real numbers, not assumptions about future conditions.
The Bottom Line
The data points in one direction: Contra Costa County, including East County, is still a market where a prepared seller can achieve a strong outcome. Low inventory, a 100% sale-to-list ratio, and sub-30-day average selling times countywide are not the metrics of a market that has turned against sellers.
What they are is a market that rewards preparation and honest pricing. If you want to know where your home fits in this picture, I can put together a current market analysis for your specific address. No pressure, just real numbers.
