Lot
The seller is offering the front portion of the property for sale under ML82028983. This front area is ideally positioned closest to the paved road cul-de-sac and existing utilities. In May 2025, sellers' civil engineer and architect to prepared a proposed lot line adjustment and subdivision plan for the development of two luxury residences, each approximately 4,500 square feet. The lot line adjustment would create two amazing lots one at approx. 27,200 sf and the second at approx. 40,000sf , the larger lot has views of the SF bay and city lights. Build a luxury home for yourself and the second for resale! Preliminary plans for the proposed lot split and building design plans are available for to view. Per the seller, the anticipated lot line adjustment process could take approximately two to three months to complete. The new owner would be fully responsible for obtaining any/all applicable costs for submission, review, permit, building fees, reports and surveys. New owner may choose to proceed with the existing architectural plans or create their own custom home design. With much of the preliminary groundwork for the lot line adjustment is already completed, this opportunity could significantly accelerate the development timeline.
