SAN FRANCISCO (AP/KTVU) -- 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, TMZ reported Monday.

According to the website Montana says his fancy condo is "slanted" and he's going after the developers, Millennium Partners. 

Montana says he bought a unit in 2013 for $2.7 million. 

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.

In March the homeowners association for Millennium Tower filed a lawsuit to force the fix for the sinking.
