Contra Costa Housing Market Update

County-wide picture: The median list price county-wide is $922,811 as of May 25, 2026, with inventory rising to 1,409 homes and the Market Action Index sitting at 48 — still in seller's territory, but down slightly from 49 last month. Buyers are finding more room to negotiate, particularly in the mid-market and move-up segments, with days on market lengthening and price reductions appearing on overpriced listings.

Notable takeaways by tier:

Luxury segment — Danville is the standout performer, with home prices up 8.2% year-over-year in March 2026, reaching a median of $1.9M, though homes are now taking 14 days versus 10 days last year. San Ramon is softening: prices were down 10.9% year-over-year in March 2026 at a median of $1.5M, with days on market stretching to 20 days from 12 last year. Lafayette's typical home value sits at approximately $1.9M, down 6.9% over the past year.

Mid-market — Concord continues to see strong activity: homes sold for a median of $739,475 in April 2026, with 303 homes sold — up from 280 last year — and days on market tightening to 22 days from 24. Brentwood shows a notable shift toward a buyer-friendly pace: the median sale price hit $824,300 in April 2026 with days on market jumping sharply to 56 days, compared to just 34 days last year. Martinez dropped 10.5% year-over-year to a median of $725,000 in March 2026.

Affordable segment — Richmond is holding strong: home prices were up 3.8% year-over-year over the three months ending April 2026, with a median of $644K, and the price per square foot rising 7.8%. Oakley is the weakest performer in this tier: prices fell 5.2% year-over-year in March 2026 to $635K, with days on market rising from 18 to 28 days. Antioch edged up 1.5% to a median of $601K in March 2026, with days on market actually improving from 31 to 21 days. Pittsburg was essentially flat, up just 0.9% to $561K, while homes there now sell in about 11 days.

The overarching theme: the higher-end markets (San Ramon, Lafayette, Martinez) are cooling noticeably, while more affordable cities like Richmond and Antioch are showing modest resilience. Rising inventory and longer days on market across most cities signal a gradual shift toward buyer leverage heading into summer.
