U.S. Bank Tower, known locally as the Library Tower and formerly as the First Interstate Bank World Center, is a 1,018-foot (310.3 m) skyscraper in downtown Los Angeles, California. It is, by structural height, the third-tallest building in California, the second-tallest building in Los Angeles, the 24th-tallest in the United States, the third-tallest west of the Mississippi River after the Salesforce Tower and the Wilshire Grand Center, and the 129th-tallest building in the world, after being surpassed by the Wilshire Grand Center. However, the U.S. Bank Tower does surpass both the Salesforce Tower and the Wilshire Grand Center in roof height, making it the only building in California whose roof height exceeds 1,000 feet (300 m). Because local building codes required all high-rise buildings to have a helipad, it was known as the tallest building in the world with a rooftop heliport from its completion in 1989 to 2010 when the China World Trade Center Tower III opened. It is also the third-tallest building in a major active seismic region; its structure was designed to resist an earthquake of 8.3 on the Richter scale. It consists of 73 stories above ground and two parking levels below ground. Construction began in 1987 with completion in 1989. The building was designed by Henry N. Cobb of the architectural firm Pei Cobb Freed & Partners and cost $350 million to build. It is one of the most recognizable buildings in Los Angeles, and often appears in establishing shots for the city in films and television programs.

1100 Wilshire is a 37-story, 151.18 m (496.0 ft) residential and commercial skyscraper completed in 1987 in Los Angeles, California. It is the 24th tallest building in the city, the 2nd tallest residential building in the entire Southern California region, and the 4th tallest residential building in the state of California. The 35,262 m2 (379,560 sq ft) tower was designed by AC Martin Partners. The bottom 16 floors are primarily parking, with commercial space on the ground floor/street level. 1100 Wilshire was unsuccessful as an office building and sat nearly vacant for almost two decades. It was purchased by Hampton Development, TMG Partners and Forest City Residential for $40 million, and from 2005 to 2006 the property was converted to owner-occupied residential condominiums with 228 units.
Wilshire Grand Center is a 1,100-foot (335.3 m) skyscraper in the financial district of downtown Los Angeles, California, occupying the entire city block between Wilshire Boulevard and 7th, Figueroa, and Francisco streets. Completed in 2017, it is the tallest building west of Chicago. Though the structural top of the Wilshire Grand surpasses L.A.'s U.S. Bank Tower by 82 ft (25 m), the roof of the U.S. Bank Tower is still 90 ft above the Wilshire Grand's. The Skyscraper Center lists the Wilshire Grand Center as the 15th-tallest building in the U.S. and the 95th-tallest in the world. It won the Structural Engineering Award 2019 Award of Excellence from the Council on Tall Buildings and Urban Habitat.
