The United States Courthouse at 350 W. First Street in the Civic Center district of downtown Los Angeles opened in October 2016.

It is 10 stories tall with 533,000 square feet (49,500 m2) of floor space, containing 24 courtrooms and 32 judicial chambers and stands out in the downtown skyline with its impressive glass façade.
