Stearns established a stagecoach route connecting San Pedro Bay with the Pueblo de Los Ángeles.

Casa de San Pedro is described as an adobe hide house in the book Two Years Before the Mast by Richard Henry Dana published in 1840.

Casa de San Pedro was part of the beginning of the Port of Los Angeles.

In 1846 the Mexican governor of Alta California, Pío Pico, directed that a 500-vara-square of land (43 acres) facing onto San Pedro Bay be set aside as a government reservation.
