One Hawthorne: seven closings this year at $914 a foot, in half the days of last year, one block from Harvey's 150,000 square feet
Every 2026 closing at One Hawthorne, the 2010 EHDD tower at Howard and Hawthorne, against the record since 2012
Seven closings at 1 Hawthorne Street through October 15, against six in the 2025 window; $7.3 million of volume against $7.0 million. Median sale $797,004; median $914 a square foot against $967, and 31 percent under the building's 2016 high of $1,327. Median days to contract fell from 50 to 21.
One Hawthorne sold the same number of condominiums as last year in less than half the time. Seven closed at 1 Hawthorne Street between January 1 and October 15, 2026, against six in the same window of 2025; $7,296,804 of volume against $7,024,000. The median listed sale went into contract in 21 days, against 50 last year.
The median sale, $797,004, is under last year's $1,222,500 because four of the seven were one-bedrooms, at a median of $719,500 and $870 a foot. The two two-bedrooms went at a median of $1,575,400 and $1,141 a foot. Across all seven the figure is $914 a foot, against $967 in the 2025 window and the building's high of $1,327 in 2016; the tower has sat under $1,000 since 2024 after a decade above it.
The two paired resales on record run in opposite directions, and the unit explains more than the year. #17F, a 1,381-square-foot two-bedroom on a high floor, was bought in November 2022 for $1,515,000 and sold on April 17 for $1,651,800, up 9 percent, after 21 days; it is the high sale of the year. #3G, 860 square feet on the third floor, was bought in March 2021 for $899,000 and sold on July 14 for $710,000, down 21 percent; it is the low sale, and it never listed.
#4H, 1,380 square feet, closed at $1,499,000 on July 31 after 82 days. Two transfers under $300,000 are left out of every median. The tower is 24 stories and 165 units, designed by EHDD for Jackson Pacific Ventures and MacFarlane Partners on an eight-story limestone-clad podium, and finished in 2010 with the Transbay center still a hole in the ground (EHDD; SocketSite).

Howard and Hawthorne, between Second and Third
One Hawthorne stands on Howard at Hawthorne, the short street between Second and Third, with the Yerba Buena gardens around the corner. One block west at Third and Howard is 201 Third, the 13-story Kilroy building where Harvey AI signed 92,000 square feet in June 2025 and, as reported on April 6, 2026, took two more floors for about 150,000 in total; Amplitude has 57,500 square feet in the same building, and a Sextant coffee bar opened in its ground floor in March 2025 (CoStar; CoStar; Yerba Buena Partnership). One block south, ZIP signed at 680 Folsom in 2025 (Yerba Buena Partnership).
Two blocks east along Howard, the four Foundry Square buildings at First Street, 400, 405, 500 and 505 Howard, are all leased to Anthropic, and the company took the whole of 300 Howard at Beale in February 2026 (Bisnow; Business Wire). The 2025 openings on the surrounding blocks were SHOJI at 140 New Montgomery in April and the Golden Eye Social darts bar at 311 Third at Folsom in May (Yerba Buena Partnership).
The timetable that every South of Market building now sits inside is the public-offering calendar. Anthropic filed a confidential draft registration with the SEC on June 1, 2026, a week after a funding round that set its valuation at $965 billion (TechCrunch). As of this week the Standard reports the Anthropic listing has been pushed to November, after the midterms, that OpenAI's has moved to 2027, and that Anthropic is weighing a lockup longer than the usual six months (SF Standard). The same piece carries a Redfin estimate that current and former OpenAI and Anthropic employees could in theory buy close to a third of the metro area's homes with their proceeds, and the counter-argument from UC Berkeley's Enrico Moretti and the Bay Area Council's Jeff Bellisario that the money is concentrated in fewer hands than past booms and that these firms create fewer jobs per dollar because so much goes to data centers rather than headcount. The record in this report ends on October 15. None of it reflects a single share that has been sold.
Two citywide facts frame every building figure here. First, the office recovery is lopsided: CBRE put Q3 2026 vacancy at 27.7 percent citywide, down 6.6 points in a year, but Avison Young splits that into roughly 12 percent for Class A and north of 31 percent for Class B, and a Presidio Bay executive told Bisnow the headline number is misleading for that reason (Bisnow). Second, the condo market is still digging out: the Chronicle's May analysis found that only eight Bay Area ZIP codes showed inflation-adjusted condo gains over the year, all of them in San Francisco, and that Noe Valley's typical condo remained close to $400,000 below its 2019 level in real terms (SF Chronicle).
How this was counted
Two records feed this review. The MLS layer is one row per listing and carries days on market and square footage. The county layer reaches back further and catches transfers that never listed, but records the same closing once per data source, so the two were merged on unit, date and price and each closing kept once. Below-market-rate units and transfers under $300,000 are listed but excluded from every median. "Same window" means January 1 to October 15 of each year. Nothing here is a valuation of any unit, and nothing here is advice.
