The house was built in 1836 by Roberto Balermino (Tamien of the Ohlone tribe), fourteen years before California's admittance to the Union.

The California Pioneers of Santa Clara County, a non-profit organization, obtained this property with the intention of establishing a no-cost museum for the public's benefit.

[7] Spanish-born businessman Don Antonio Suñol (1796–1865) obtained the Rancho Los Coches in 1847 from Balermino in payment of a debt.

Splivalo made several modifications to the property, including adding a second story, a balcony, and covering the brick walls with wooden siding.

John Bruzzone Sr. eventually inherited the family business and became the owner of the land situated behind the adobe home site.

[3] The California Pioneers of Santa Clara County, a non-profit organization, established a no-cost Roberto Adobe & Suñol House Museum in August 2016.
