For several years, services for parishioners were held in various temporary locations. In 1935, fundraising began for the purchase of a building for the church, and by 1937, this idea was successfully realized. With voluntary donations from parishioners, the cathedral was restored, and on October 17, 1937, the consecration ceremony took place. In the following years, the cathedral expanded, with an altar and iconostasis added inside.

After World War II, when many Russians from Europe and the Far East arrived in Los Angeles, a Russian school was opened at the church.

Since the 1950s, the parish began planning the construction of a large cathedral. The Society of Zealots collected funds for 30 years, and in 1979, the construction of the new stone church began. When half of the work was completed in 1982, services began in the church, although it still lacked domes. Now, the three-altar cathedral is adorned with 10 domes, and the iconostasis contains 130 icons painted by the iconographer and choirmaster from San Francisco, Vladimir Krasovsky. Services at the Transfiguration Church are mainly conducted in Church Slavonic, with little use of English.
