What sets 740 Clipper Hill apart is not simply its acreage, but how much of the property you can actually use and enjoy. With two separate residences set on substantial usable land, the property offers a combination of flexibility, privacy and setting that is difficult to replicate. Positioned at the top of the hill, it enjoys direct Mount Diablo views and adjacency to Las Trampas Regional Park. Just as importantly, it offers features rarely found in a setting like this: public water, generous access and parking, and a newer, separate 900± square-foot, 2BR/2BA ADU with carport.
