Property established from the subdivision of the former Ranchos Los Guillicos, Los Alamos Ranch is an extraordinarily rare offering of 214 ± acres. Well situated in the Sonoma Valley, the Ranch is located precisely halfway between Kenwood to the East and Santa Rosa to the West.


The property consists of two APNs that are comprised of 5 separate ACCs. The smaller of the APNs (#032) measures 66.55 ± acres which are situated within Santa Rosa's "Sphere of Influence". This determination establishes the potential for annexation when the city's General Plan is updated in the year 2020.


The 'highest and best' suitability for this piece of the Los Alamos Ranch may be as a Sonoma Valley AVA estate winery and event center (with vineyard development of approximately 35 acres of vines). Yet another unique highlight of this particular portion of the property is the 15 ± acre-foot pond, suitable for irrigation or recreation.


The larger of the two APNs (#016) spans 147.61± acres and contains within, 4 ACCs that range in size from 7± acres to 119± acres. There are four potential building sites (subject to the policies and standards of the Permit Resource Management Department of Sonoma County).


The largest of the ACCs, designated number 4, has a vintage farmhouse originally built in 1930 with more recent expansion and updating. It measures 1210 ± square foot with 2 bedrooms and 2 bathrooms.
