It sits in the grounds of the California Nursery Co. at Niles Boulevard and Nursery Avenue in the Niles District of Fremont, Alameda County, California.","why_significant":"The adobe is described as the first of the Vallejo adobes built in the area, tied to Jose de Jesus Vallejo and his Rancho Arroyo de la Alameda. It is also called a picturesque reminder of the adobe era, set within the gardens of the California Nursery, founded in 1865. Areas of significance are checked as agriculture and architecture.","narrative":"This small adobe house stands in the grounds of the former California Nursery Company in the Niles District of Fremont. Built around 1855 of sun-dried brick made from native soil, it has a single room, about 1100 square feet, and exterior walls 28 inches thick at the foundation. It is described as the first of several adobes built in the area by Jose de Jesus Vallejo, who received the 17,705-acre Rancho Arroyo de la Alameda in 1842 and was active in military and civil affairs, including service at Mission San Jose. The building was later restored for use as a guest house in the nursery gardens. The nursery, founded in 1865, helped shape the state's fruit industry and home landscaping. The tile roof, beams, floor and fireplace may not be original, though the building is thought to resemble its early appearance. The listing covers the adobe and about 0.35 acres, not the wider nursery grounds, which were threatened by subdivision.","period_of_significance":"19th Century (est. 1855)","architect_builder":"Built by Jose de Jesus Vallejo (as one of the Vallejo adobes)","architectural_style":"Adobe","criteria":[],"status_note":"Described as in fair condition, restored and maintained over the years as a guest house, needing continued maintenance, with some spots beginning to deteriorate.
