South San Francisco, CA Housing Market 2026: What Homes Actually Sell For

If you invest in or around South San Francisco, the number that matters is what homes actually close for, not what sellers are asking. Here is what South San Francisco sale prices look like right now, built from the closings Resideline tracked over the last six months, as of August 2026.

• •Closings tracked, last 6 months: 191

What the numbers say

Resideline tracked 191 closed sales in South San Francisco over the last six months, with a median closing price of $1,240,000. That median is the midpoint of what buyers actually paid, not what sellers hoped to get, which is why it moves differently from the asking prices you see on listing sites. The middle half of those sales closed between $950,000 and $1,407,500. That spread matters more than the headline median: where a specific property sits inside it decides whether the citywide number helps you or misleads you. These are the closings Resideline tracks and may differ from complete county or municipal records. Across the 190 closings with usable living area, the middle half sold between $679 and $1,000 per square foot.

The South San Francisco angle

South San Francisco cuts both ways. The band from $950,000 to $1,407,500 is narrower than most markets we track, which makes $1,240,000 a more usable starting point than it would be elsewhere. The narrow band is the more useful fact for pricing. When closings cluster inside a compact range, a valuation that lands far outside $950,000 to $1,407,500 needs a specific, documented reason tied to the property itself. The lower part of the band, from $950,000 to $1,240,000, is the wider side, so the distribution reaches further downward from the middle than upward. A comp set built from the upper part of the range will therefore read high on a smaller or less updated property. And half of all closings sit outside the band altogether, at both ends.

From market read to offer price

A market read is the backdrop. The decision still comes down to one property and one number: what it is actually worth and what you should pay. Every Resideline report opens with this same market snapshot for the subject's exact ZIP code, then gives you the property's value, the sold comps behind it, and a market rent estimate. Pricing a specific deal? The free ARV calculator and rental property calculator run the numbers in about a minute.

And we show our work. Every estimate is frozen while the home is for sale and graded against the real closing price after it sells. As of August 2026, the public scoreboard showed 3.26% median error across 12,508+ graded closings. See the live accuracy dashboard for the receipts, or read how the Area Market Snapshot works.

Every local market figure on this page is computed from closed sales Resideline tracked in South San Francisco over the last six months, and is refreshed when the data is. The closings we track inside the city limits are not limited to listing-service sales: they also include foreclosure deeds, estate and family transfers, and other off-market sales that portal medians exclude, which is why 15% of the 191 closings in this window never appeared on a listing service, and the median of MLS-listed sales alone was $1,245,000.
