YMCA Building, Community center in Riverside, California, US

The YMCA Building is a 40,000-square-foot structure in downtown Riverside, California, designed in the style of an Italian Renaissance palazzo. Its main floor holds three halls rented for wedding receptions, business events, graduations and quinceañeras, while the top floor has 25 studios rented by artists. The ground-floor gymnasium now stands vacant.

Built in 1909, this was Riverside's second YMCA building. The YMCA left in 1968 for premises at 4020 Jefferson Street. In 1974 Bent Corydon bought and refurbished the 40,000-square-foot structure as a Church of Scientology franchise, then the church's largest Mission; he left a few years later and won a ten-year legal battle for ownership in 1992.

The building's name survives in its current use: the Life Arts Center rents three main-floor halls for wedding receptions, business events, graduations and quinceañeras. The top floor holds 25 artist studios, once the hotel rooms where YMCA guests stayed. The former gymnasium on the bottom floor stands vacant.

The building stands in downtown Riverside at 33.94060, -117.42000. The three halls on the main floor are rented for events, so entry depends on a booking; the 25 artist studios on the top floor and the vacant former gymnasium on the bottom floor are not open to casual visitors.

The building's 40,000 square feet made it the largest Mission of the Church of Scientology when Bent Corydon bought and refurbished it in 1974. Corydon later left the church and won a ten-year legal battle for ownership in 1992; he is now president of Life Arts Center Incorporated, which owns the building.
