Paramount, San Francisco, Residential skyscraper in South of Market, San Francisco, United States.

Paramount is a residential skyscraper in the South of Market district of San Francisco, standing at the corner of Mission Street and Third Street. The tower rises 40 floors and holds around 500 apartments a short walk from the city center.

The Paramount was completed in 2001 as a 40-story, 420-foot (128 m) concrete-framed rental tower at 680 Mission Street. It was the tallest all-residential building in San Francisco from 2001 to 2008 and, at completion, the tallest concrete-framed structure in Seismic Zone 4. It is one of several highrises built on Mission Street since 2000, alongside 555 Mission Street, the St. Regis Museum Tower and Millennium Tower.

The tower's name comes from its developer, and its address, 680 Mission Street at Third, is how locals identify it. Since 2000 it has stood among a cluster of new Mission Street highrises, including 555 Mission Street, the St. Regis Museum Tower and Millennium Tower. Its roughly 500 rental apartments keep the block occupied day and night.

The building sits in a well-connected part of San Francisco, close to bus lines, train stations, restaurants, shops, and entertainment venues. Many neighborhoods and landmarks are easy to reach on foot or by public transit from here.

When it was completed, the building was the tallest concrete-framed structure in its seismic zone, which set it apart as an engineering feat in earthquake-prone San Francisco. This construction method allows the tower to absorb ground movement in ways that many older downtown buildings cannot.
