1990 Green, the 1926 Edwardian with the 360-degree roof deck near Union Street: one closing this year, a raised-corner one-bedroom listed at $949,000 and sold at $1,030,000 in four days, $1,241 a foot

1990 Green's one sale this year took four days and went $81,000 over its list. One condominium closed between January 1 and October 15, 2026, on $1,030,000 of volume; nothing closed in the same window of 2025. The price per square foot is $1,241, against $1,117 on the 2023 window sale, $1,267 across the two 2023 sales in all and $1,533 across the two sales of 2022, when a $2,300,000 sale set the building's high.

#107, an 830-square-foot corner one-bedroom raised above the street with ten-foot ceilings, a bay window and two walk-in closets, was listed on January 23 at $949,000, went pending on January 28 and closed at $1,030,000 on February 10, four days from listing to contract; its dues run $699 a month, and there is street parking only; the listing record shows it sold at $877,500 in 2017, $800,000 in 2013 and $630,000 in 2005, pairings the site's record does not hold (Redfin). The building's top-floor #601 sold at $2,125,000 in 2023 with dues of $1,150 (Warrin).

The building dates from 1926, an Edwardian elevator building with original picture-frame moldings, a community laundry and a roof deck with views of the Golden Gate, Alcatraz and Coit Tower, on the north side of Green between Laguna and Buchanan; the listing record counts 29 units, and the building record on this site lists nine (Redfin; Redfin street index).

2026 so far, against the same window in 2025

Closings at 1990 Green St between January 1 and October 15, 2026, set against January 1 to October 15, 2025. Days on market is median days from listing to contract on MLS-listed sales; "under 15 days" counts how many of those went into contract inside two weeks.

By bedroom count, 2025 against 2026

Every closing in 2026

All 1 closings through October 15, 2026, highest price first. Square footage and days on market are as recorded on the MLS; county-recorded transfers that never listed show no days.

Green Street, around the corner from Union

Union Street's shops are around the corner, with Moscone Park, Fort Mason and the Marina Green a short walk north (Redfin). On Union, the Mission burrito shop Breakfast Little announced in April 2026 that it is taking the former Gamine space at 2223 Union, and two blocks north at 1973 Greenwich a four-story front building is adding a one-bedroom and a four-bedroom townhouse (Hoodline; SF YIMBY). A block west at 2100 Green, the 1927 cooperative on the corner of Webster, the penthouse transferred at $5,320,000 in May (Redfin, 2100 Green #800).

No AI office of any size is within walking distance; the nearest are startup house headquarters in the Marina and on Russian Hill reported without addresses, and the office figures in the paragraphs below describe SoMa, three miles southeast (SF Standard).

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.
