It’s the leaning tower of San Francisco.

The Bay Area’s Millennium Tower has only continued to tilt further and sink deeper west in spite of architects’ best efforts to steady the ritzy building.

The multimillion-dollar-per-unit tower is now leaning more than 29 inches at the corner of Fremont and Mission streets — a slant over half an inch deeper than previously revealed, according to monitoring data reviewed by NBC Bay Area’s Investigative Unit.
