1001 17th Street, the 26-unit 2015 building on the north slope of Potrero Hill: one closing this year, a one-bedroom at its $800,000 list, $5,000 under its 2016 developer price

1001 17th Street sold one condominium this year at the lowest per-foot figure in its record. One unit closed between January 1 and October 15, 2026, against one in the same window of 2025; $800,000 of volume against $620,000. The price per square foot is $856, against $1,049 on last year's sale, $1,002 in 2024, $1,138 across two sales in 2022, $1,078 across three in 2020 and $1,212 across the ten developer sales of 2016, the most in any year.

#101, a 935-square-foot one-bedroom with radiant floor heat and in-unit laundry, was listed on March 16 at $800,000 and closed at $800,000 on April 20; the MLS feed records no days on market, and the listing record shows 25 days from listing to contract with the same agent on both sides; its dues run $562 a month and include internet; the listing record also shows the unit sold new in June 2016 for $805,000 after a $895,000 ask was cut to $799,000, a pairing the site's record does not hold (Redfin; Redfin, 2016 record). The building's #303 sold in February 2022 at $625,000 with dues of $438 (Redfin, #303).

The building is a 2015 elevator building of 26 units on the north slope of Potrero Hill, with a courtyard with a fire pit and barbecue, a bike room and a small park outside; the building record on this site lists 12 units and 2016 as the year, which the assessor also uses (Redfin, #101; HotPads; Redfin street index).

17th Street, the north slope of Potrero Hill

The listing places the building between Potrero Hill, Mission Bay and Dogpatch, with Plow, Philz, Whole Foods and UCSF in the walk (Redfin, #303). Across the hill's north face, 146 Missouri, a fire-destroyed 1913 Queen Anne between Mariposa and 17th, has permits filed for a four-story two-unit replacement, reported in March 2025, and 210 Mississippi at Mariposa offered a 3,573-square-foot second-floor creative office at $6,800 a month in May 2026 (SF YIMBY; LoopNet brochure).

The nearest AI office is Resolve AI's top floor at 350 Rhode Island, the converted recycling plant in Showplace Square about four blocks west, reported in August 2025; OpenAI's Mission Bay buildings at 550 Terry Francois and 1800 Owens are half a mile northeast (CoStar; Bisnow).

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.
