The lawsuits are piling up at the "leaning tower" of San Francisco.
Millennium Tower is a luxury residential high-rise that has sunk 17 inches and tilted 14 inches since it was completed in 2008. Though an inspection by the city showed it's safe to occupy, the situation has sparked an exodus from the building. Residents say they're selling multimillion-dollar condos at a loss, with the value of their homes tumbling $320,000 on average.
There are at least 20 parties involved in lawsuits related to Millennium Tower, according to a "60 Minutes" segment that aired on Sunday. One disgruntled resident told producers that with so many lawyers involved, it takes the court 30 minutes just to take attendance during legal proceedings.
