About $813,000 is the middle of the market. The median Martinez home sold for $813,462 in August 2026, up 4.3% from a year earlier, and a typical single-family house went for $849,502 (Redfin, Martinez housing market page, August 2026, checked September 24, 2026).
That’s the city number. Your number depends on the house, the street and the shape it’s in. Here’s what the August data says and how to use it.
What did Martinez homes sell for in August 2026?
Close to asking, and a bit slower than last summer. These are Redfin’s figures for all home types in Martinez (Redfin, Martinez housing market page, checked September 24, 2026):
- Median sale price: $813,462, up 4.3% from August 2025. Redfin’s own summary frames the $813K as the median over the three months ending August 2026.
- Median price per square foot: $485, up 0.7% from a year earlier.
- Homes sold: 102 in August 2026, compared with 97 in August 2025.
- Median days on market: 20, compared with 14 a year earlier.
- Sale-to-list price: 100.1%, down 0.9 points. The typical home closed right at its asking price.
- Sold above list price: 44.5% of homes, down 11.2 points.
- Homes with a price drop: 31.2%, down 0.62 points.
So prices held up, but the bidding cooled. Fewer homes went over asking than a year ago, and they took almost a week longer to sell.
How do single-family homes, townhouses and condos compare?
Big gaps by type, so compare like with like. Redfin’s August 2026 figures by home type (Redfin, Martinez housing market page, home type tabs, checked September 24, 2026):
| Home type | Median sale price | Change from Aug 2025 | Sold in Aug 2026 | Median days on market |
|---|---|---|---|---|
| Single-family | $849,502 | up 3.7% | 83 | 18 |
| Townhouse | $677,545 | down 1.2% | 10 | 31 |
| Condo or co-op | $449,864 | up 4.6% | 7 | 25 |
Read the townhouse and condo rows carefully. With only 10 and 7 sales, one unusual sale can move the median a lot. Single-family homes were 83 of the 102 August sales, which is why the all-types median sits close to the single-family number.
Is the Martinez market competitive right now?
Yes, by Redfin’s measure, but less than a year ago. Redfin gives Martinez a Compete Score of 85 out of 100, which it labels “Very Competitive.” It says the average home sells for about 1% over list and goes pending in about 21 days, while its “hot homes” sell for about 3% over list in about 10 days (Redfin, Martinez housing market page, checked September 24, 2026).
The honest read: a clean, well-priced house still draws offers. A house priced above the recent sales on its street is more likely to join the 31% that cut their price.
How far are prices from their peak?
Still below it. Redfin’s monthly median sale price for Martinez hit $915,000 in May 2022. The August 2026 median of $813,462 is about 11% under that high (Redfin, Martinez housing market page, five-year history, checked September 24, 2026).
For county context, C.A.R. puts the Contra Costa County median for single-family homes at $875,000 in August 2026, up 2.9% from a year earlier, with county sales down 4.1% (C.A.R., August 2026 home sales and price report, September 16, 2026). That county figure uses a different method than Redfin’s, so don’t subtract one from the other.
Why might a Martinez house cost more or less than the median?
Because Martinez homes vary a lot. A median is just the middle sale of whatever sold that month. Things that move a single price:
- Home type and size. The single-family and townhouse medians above are about $172,000 apart.
- Age and condition. Older houses near downtown sit a short drive from newer tracts. Updated systems and a clean inspection matter to buyers.
- Commute setup. Martinez has no BART station. The Amtrak station on Marina Vista Avenue and County Connection buses to Concord, Pleasant Hill and Walnut Creek BART are the transit options, so buyers weigh the drive to the station, Highway 4 and I-680.
- What’s nearby. The Martinez Refining Company refinery, owned by PBF Energy, is next door to the city. Buyers will ask about it. Contra Costa County posts its oversight records for the plant, and you can read them yourself (Contra Costa County Fire Protection District, Martinez Refining Company Oversight page, checked September 24, 2026).
How do I find what my house or the one I like is worth?
Pull the recent sales of homes like it. Same type, similar size, same part of town, sold in the last few months. That tells you more than any city-wide median, including this one. Get a free home value estimate as a starting point, then have an agent walk the house.
