Sam Altman's infinity pool flooded his $27 million Russian Hill mansion, according to a lawsuit

    • Sam Altman's $27 million mansion is plagued by defects, according to a lawsuit.

    • The lawsuit also alleges that developer Troon Pacific was aware of significant problems before the home was sold.

    • According to the complaint, Altman was dealing with sewage problems, water leaks and mold.

    Sam Altman isn't happy with his $27 million mansion.

    In a recent lawsuit filed in San Francisco Superior Court on behalf of a home at 950 Lombard St. that public records show is linked to the CEO of OpenAI, local developer Troon Pacific is accused of overselling one of San Francisco's most expensive homes.

    The complaint alleges that developers failed to disclose that the home was riddled with construction defects. It also alleges that the CEO of Troon Pacific “was aware of widespread and significant defects” in the home but sold it to Altman anyway.

    The San Francisco Chronicle was the first to report the lawsuit, and the SF Standard reported on Altman's connection to the house.

    The OpenAI CEO experienced multiple incidents at home, including raw sewage dumping on the side of his house, “a crushed sewer pipe running from the laundry system to the toilet causing water to overflow,” and multiple water leaks, the lawsuit said.

    In August, flooding penetrated the “entire subfloor of the lower level” of the home, causing widespread mold, the complaint said. The lawsuit said it would cost $4 million to repair the home.

    According to the complaint, the water source was the much-advertised infinity pool, the design and installation of which were “poor and substandard in terms of water tightness.”

    “In short, the owner was deceived into purchasing a $27,000,000 ‘lemon,’” the indictment said.

    The ostentatious San Francisco mansion has been featured in several news and magazine articles. It features a Batcave-like garage with a turntable for cars and views all the way to Alcatraz Island.

    There is also a coyote problem in the house.

    “This coyote has come into my house and is scratching on the door outside,” Altman told Time in a December interview. “It's very cute, but at night it's very annoying.”

    Representatives for Altman, 950 Lombard LLC and Troon Pacific did not immediately respond to a request for comment.
