The segment read

94509 meets
single-family homes.

Detached single-family homes are the dominant stock in every city I work — usually 60–80% of listings. What they look like varies enormously block to block: 1960s ranch homes in the older zips, 1990s two-stories in the midlevel subdivisions, and a handful of true custom builds in the hills. Price-per-square-foot is the single best comparison metric here; if someone quotes you a median without a PSF, push back.

Inside 94509 specifically, inventory concentrates in Rivertown, central Antioch. If any of those areas interest you, I can tell you which blocks have the right lot profile for this house type and which don't.

Families who need the yard, the garage, the driveway, and room to grow into — or sellers sitting on equity in a home they raised kids in.

Questions

Single-Family Homes in
94509.

Are there many single-family homes active in 94509?
Varies. 94509 has roughly 62 total listings right now; single-family homes typically represents a portion of those. I pull exact segment counts from the MLS before each tour — fresh numbers matter.
Where do single-family homes concentrate inside 94509?
Mostly in Rivertown, central Antioch. Each block inside the zip has its own character — some neighborhoods lean more toward one house type than others. I'll steer you to the right pockets for what you're looking for.
How has single-family pricing moved in 94509?
94509's overall median sits around $491K, and single-family homes trades within that range depending on address and condition. I run segment-specific comps before any offer.
Are single-family homes appreciating in Contra Costa?
Yes, though unevenly. Central county (Walnut Creek, Pleasant Hill) is flat to up. East county (Antioch, Pittsburg) is climbing faster off a lower base. Median numbers hide neighborhood-level differences.
How much should I budget for closing costs?
Plan for roughly 2.5–3% of purchase price for a buyer. Title, escrow, loan fees, first-year insurance, and prorated taxes stack up. I walk every first-time buyer through a line-item estimate before we write.
Is new construction actually a good deal in Antioch?
Sometimes. Deer Valley builders have been offering interest-rate buy-downs and closing cost credits that move the real price. Other builders are padding the premiums. I read the incentive math before you sign anything — some are great, some aren't.
