The Don Fernando Pacheco Adobe is significant for its adobe construction and for its place in the exploration and settlement of California.

The adobe house is sited on what was the Rancho Monte del Diablo. It was built between 1845 and 1855 on a 1500-acre tract given to Fernando Pacheco by his father Salvio Pacheco. The senior Pacheco had held high offices in the government of Mexican California and was granted 18,000 acres, which today encompass the City of Concord and its environs.

The Salvio Pacheco Adobe (California Landmark 515) is located in what is now the downtown section of the City of Concord near other structures. It has been significantly altered so that its former rural setting and character have been drastically changed. The Fernando Pacheco Adobe is situated on more than five acres of land and is adjacent to a 25 acre City park, so that it still retains the ambience of early California living. The architectural style and setting of the house are excellent examples of Mexican California architecture.
