Yucaipa Adobe

Diego Sepulveda, nephew of Antonio Maria Lugo, put this adobe up in 1842 on land the Lugos had just been granted, and it is generally called the oldest house in San Bernardino County. It stands on the Yucaipat village site, which is the other plaque here. After Sepulveda it passed to John Brown senior, then James Waters, then the Dunlap family, and in 1955 the county bought it. Two hundred years of ownership, and the first owners are the ones without a deed.

What the plaque says

Constructed in 1842 by Diego Sepulveda, nephew of Antonio Maria Lugo, this is believed to be the oldest house in San Bernardino County. The land, formerly controlled by San Gabriel Mission, was part of Rancho San Bernardino, granted to the Lugos in 1842. Later owners included John Brown, Sr., James W. Waters, and the Dunlap Family before acquisition by San Bernardino County in 1955.
