SAN FRANCISCO (AP) – Former San Francisco 49er Joe Montana has filed a lawsuit against the developers of a luxury high-rise condominium tower that is sinking at an unexpected rate. San Jose television station KNTV reports Montana filed the last suit last week alleging Millennium Partners hid the building’s troubles when he and his wife bought a unit in 2013. The high-rise that opened its doors in 2009 has sunk about 16 inches into landfill and is tilting several inches to the northwest. Montana’s is the latest in a string of lawsuits against the tower that became a haven for the well-heeled. Tenants have included the late venture capitalist Tom Perkins and Giants outfielder Hunter Pence. The building has a sprawling indoor lap-pool, a health club and spa, an in-house cinema, and a restaurant and wine bar run by celebrity chef Michael Mina. Penthouses have sold for more than $13 million.
