Peralta Home, Spanish Colonial residence in San Leandro, California, US

The Peralta Home at 561 Lafayette Avenue in San Leandro is a brick house built in 1860 in the Spanish Colonial style. A.C. Peachey added a large wood extension at the back in 1875. Technically a 2+1⁄2-story building, its main reception rooms are on the second story, and Peachey treated the ground floor as a basement.

The Peralta Home was built in 1860 for Ignacio Peralta, an early San Leandro Spanish settler, by his son-in-law William P. Toler. It was the first brick house in Alameda County. Ignacio's father, Luís María Peralta, had received the Rancho San Antonio land grant from Governor Pablo Vicente de Solá on October 20, 1820. In 1875 A.C. Peachey bought the house from Ignacio's widow, Rafaela Sanchez Peralta, and added a large wood extension at the rear.

The house is also called Alta Mira Club House and Casa Peralta. Since November 1926 it has belonged to the Alta Mira Club, which bought it from Daniel and C.L. Best and still owns it. The name recalls the Peralta family, whose Rancho San Antonio grant came from Governor Pablo Vicente de Solá in 1820.

The house sits on Lafayette Avenue where visitors can easily view its exterior details from the street and appreciate its construction style. The building has been preserved in good condition, making it possible to examine its architectural features at any time of day.

The 1875 wood extension by A.C. Peachey kept the main reception rooms on the second floor and treated the ground floor as a basement, so the house is technically 2+1⁄2 stories. The Alta Mira Club, owner since November 1926, still occupies the building.
