Who Will Pay for San Francisco's Tilting, Sinking Millennium Tower?

Who Will Pay for San Francisco's Tilting, Sinking Millennium Tower? - Bloomberg:
"...Nina Agabian, a retired director of research in global health science at the University of California, bought a 29th-floor apartment in San Francisco’s Millennium Tower in 2010.
...The building, which opened in 2008 and was touted as the most luxurious tower in San Francisco, became a beacon of the city’s burgeoning wealth, attracting tech millionaires, venture capitalists, and even the San Francisco 49ers retired quarterback Joe Montana.
The 58-story tower's shine faded on May 10, 2016, when Agabian attended a homeowners association meeting and was informed that the building had sunk 16 inches into the earth and tilted over 15 inches at its tip and 2 inches at the base, according to suits filed by residents and the city of San Francisco.
“You can imagine how distressed we were to know that, for one, our lifetime investment and savings are at risk,” she said.
“And we have no idea whether or not there’s a fix to it, and if there is a fix to it, what it will entail.”
The building, meanwhile, continues to sink.
As Agabian and more than 20 other residents file multiple lawsuits against the building’s developer, the city of San Francisco, and the Transbay Joint Powers Authority, another, potentially more ominous development has emerged.
...But according to experts, fixing whatever is causing the building to tilt could cost far more than that amount.
Further adding to residents' woes is that it's not even clear if coverage will be available under the liability policy: It might have been voided by the flaws in the building.
“I don't foresee a scenario where anyone writes a check under any policy,” said Sarah Sherman, the U.S. property practice leader at JLT Specialty USA, an insurance broker in San Francisco. “There's no way to avoid litigation at this point.”
It's possible, in other words, that homeowners already under water on their damaged real estate investments may have to cover millions in costs to repair the building.
And that's not even the extreme worst-case scenario—in 1989, some buildings on loose San Francisco soil collapsed during an earthquake.
The city has asked Millennium Partners for information on how much the building can further settle without compromising the building's stability and how it will perform during a quake.
In a letter dated January 13, 2017, MP declined to supply the city with that data, citing ongoing litigation and mediation..."
