San Francisco home prices, August 2026
The monthly home-price refresh, from the two measures that disagree usefully. Case-Shiller put the San Francisco index at 366.0 in August 2026, up 3.4% on the year. Zillow’s index valued the typical metro home at $1,120,379 in September 2026, up 3.1% on the year. They measure different things — Case-Shiller tracks repeat sales of the same homes and reports a three-month average two months late; Zillow values the entire housing stock monthly — so treat Case-Shiller as the shape and Zillow as the level.
The second chart shows the tier split, and it is the reason this post carries Case-Shiller at all: S&P divides the metro’s repeat sales into thirds by price.
