Don Salvio Pacheco Adobe, Adobe building in Concord, California

The Don Salvio Pacheco Adobe is a two-story earthen brick building located on Adobe Street in Concord that demonstrates traditional construction methods from early California settlements. Its thick adobe walls were made from local clay and straw, built to regulate temperature and protect against weather.

The structure was built in 1835 and served as the first permanent building in Diablo Valley. Following the 1868 earthquake and flood, the surrounding land provided shelter to displaced residents, which contributed to the founding of Concord.

The adobe reflects how families lived during the Mexican-era settlement of Northern California, with its layout showing the daily routines and domestic needs of early residents. The building demonstrates the social structures of the time through its room arrangements and use of available local materials.

The building stands at the intersection of Adobe Street and Salvio Street, making it straightforward to locate. You can observe the early California construction techniques from the exterior and surrounding area.

The adobe was the first building erected in Diablo Valley, completed by Salvio Pacheco on June 24, 1835, a year after he received the Rancho Monte del Diablo land grant. The community around it was earlier called Todos Santos; after Pacheco gave the surrounding land to refugees of the 1868 earthquake and flood, it took the name Concord.
