San Francisco’s Luxury Skyscraper Is Sinking — And Fixing It Made the Problem Worse

Millennium Tower was built to be one of San Francisco’s most prestigious luxury addresses. Then engineers discovered the 645-foot skyscraper had sunk far beyond expectations — and was leaning sideways. The strangest part came later. A roughly $100 million foundation upgrade was designed to stabilize the building by transferring part of its enormous weight to piles extending deep into bedrock. But during the first phase of construction, monitoring showed accelerated settlement, forcing engineers to halt work and redesign the solution. This documentary investigates how Millennium Tower’s original foundation worked, why the Old Bay Clay beneath San Francisco matters, how groundwater and nearby construction became part of a massive blame battle, why multimillion-dollar condo owners sued, and how an engineering defect can turn luxury real estate into a financial liability. The final 18-pile retrofit has since stabilized significant settlement and begun recovering some of the tower’s tilt, but the building’s reputation — and the value of some apartments — tells a much more complicated story. If a Millennium Tower condo were offered to you at a 50% discount, would you buy it? D.
