One America Plaza is the tallest building in San Diego, California and a prominent fixture in the waterfront district of the downtown San Diego skyline. The 34-story, 500 ft (150 m), 623,000 sq ft (57,900 m2),[5] obelisk-shaped tower was designed by Helmut Jahn of Murphy/Jahn Architects and KMA Architecture. The top of the building bears a striking resemblance to the end of a Phillips head screwdriver and has a similar appearance to Two Liberty Place in Philadelphia also designed by Jahn, which is a year older.[6][7][8] The building is the maximum height permitted by the US Federal Aviation Administration for a structure in downtown San Diego due to its close proximity to San Diego International Airport.[8][a]

One America Plaza was purchased by the real estate development firm, Irvine Company, in February 2006 for US$300 million.[2]

The America Plaza San Diego Trolley station is located on the ground floor of the building between the main building and the Museum of Contemporary Art San Diego.[9]

The building's elevators are supplied by Mitsubishi Electric and travel at a little over 7 m/s (1400 fpm), making them the fastest in San Diego.
