Green Hill Tower, 1070 Green, the 1961 doorman tower on Russian Hill's Paris Block: one closing this year, a two-terrace two-bedroom at $2,160,000 after 22 days, 55 percent over its 2006 price

Green Hill Tower sold one condominium this year, a 20-year hold closing out at 55 percent over its purchase. One unit closed at 1070 Green Street between January 1 and October 15, 2026, against one in the same window of 2025; $2,160,000 of volume against $1,700,000. The price per square foot is $1,301, against $1,137 on last year's window sale, $1,413 across the four sales of 2024, the most in any year, when a $4,800,000 sale closed, $1,392 across three in 2022, $1,813 across two in 2021, when a $6,200,000 sale set the building's high, and $2,139 across the two sales of 2016.

#302, a 1,660-square-foot two-bedroom renovated by an architect, facing south over two private terraces, with a deeded space with an EV charger and storage, was listed on May 21 at $2,149,000, went pending on June 12 and closed at $2,160,000 on July 10, 22 days from listing to contract; its dues run $2,976 a month and cover cable, the door person, insurance, maintenance, management, trash, water and the gym; it was bought in June 2006 for $1,395,000, up 54.8 percent, and it is the year's one paired resale (Redfin). The building's #1501, bought at $3,650,000 in 2014 in original condition, sold at about $6,900,000 in 2015 after a remodel, and #902 was relisted at $1,695,000 in 2010 after a confidential 2008 sale near $1,910,000 (SocketSite; SocketSite, Sep 2010).

The building dates from 1961, 21 stories and 48 units of 1,000 to 2,825 square feet with a 24-hour door person, on-site management, a gym and guest parking, with board approval for buyers (RubyHome; Structurae).

Green Street, the Paris Block

The tower faces the Russian Hill-Paris Block Architectural District, the 1000 block's eleven buildings at 1017 to 1067 Green listed on the National Register in 1988, among them Lewis Hobart's Bos Apartments at 1050 Green and the Feusier Octagon House of 1857 at 1067, city landmark 36, which was listed at $8,600,000 in 2021; Macondray Lane runs behind the north side of the street (Wikipedia; Wikipedia; Cottages and Gardens). Two blocks east at Royal Towers, 1750 Taylor, the penthouse was listed on August 14, 2026 at $19,998,000 (Sereno). Three blocks west on Polk, Lord Stanley closed on May 31, 2025 and the Jupiter Room martini bar is taking its space at 2065 Polk, and Bageletto is taking the former Peet's at 2193 Polk, announced in April 2026 (Wikipedia); What Now SF; SF Standard).

No AI office of any size is on Russian Hill; the nearest downtown lease is Hex's 20,000 square feet at 100 Montgomery, and the office figures in the paragraphs below describe SoMa (Traded).

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.
