Cooper Arms Apartments is a registered historic building located on Ocean Boulevard in downtown Long Beach, California.

Cooper Arms is a twelve-story steel-reinforced concrete building[2] with exterior walls of brick finished with stucco.

Located on Ocean Boulevard (at the corner of Linden Avenue) in the East Village near downtown Long Beach, the structure was designed by Los Angeles architects Curlett & Beelman.

With a construction budget of $1,350,000, the Cooper Arms was the most expensive development in Long Beach history to that time.

[2] Another popular feature was the ground-level garden along Ocean Boulevard which opened onto a Spanish loggia extending through the structure to Linden Avenue.

[5] A promotional brochure published in 1922 noted that the Cooper Arms would have the latest amenities, including steam heating, high-speed elevators, "instantaneous hot water at all times," "Iceless Frigidors," "Disappearing beds," and "Dustless roller screens.

When construction started in March 1923, the Los Angeles Times published a drawing of the Cooper Arms and described it as "an apartment-house which when completed, will be one of the most imposing structures of its kind west of Chicago.
