Millennium Tower is a luxury residential skyscraper located in San Francisco, California. Completed in 2009, it stands 645 feet tall and has 58 stories. The building features high-end amenities, including a fitness center, pool, and private dining rooms, catering to affluent residents. Despite its luxurious offerings, Millennium Tower has faced significant issues, including structural sinking and tilting. The building has settled over 18 inches since its completion, leading to legal disputes and concerns about safety. These challenges have raised questions about construction practices and building regulations in urban environments.
