One of the last premium buildable homesites in the Mount Helix area with potential for two detached primary residences under SB 9. This expansive 14,636-square-foot parcel offers a rare opportunity to create a custom estate, family compound, or multigenerational retreat in a proven luxury market, including the neighboring residence that recently sold for over $2.3 million. Enjoy a rare sense of privacy and open space with expansive undeveloped land surrounding the property and nearby Eucalyptus County Park, creating a peaceful country-estate setting rarely found so close to shopping, dining, schools, and freeway access. Significant development work has already been completed, including a dedicated 1-inch water lateral, existing ¾-inch water meter, and county-approved private improvement plans incorporating the private road and engineered sewer improvements. Parcel may allow up to two detached primary residences under SB 9; buyer to verify all development potential with the County of San Diego. This property was created through an SB 9 Urban Lot Split and may offer the potential to construct up to two detached primary residences, subject to buyer's independent investigation and approval by the County of San Diego. Unlike an ADU, a second primary residence may not be subject to the typical 1,200-square-foot ADU size limitation, creating a unique opportunity for multigenerational living, a family compound, or additional income potential. Significant development work has already been completed, including the installation of a dedicated 1-inch water lateral and existing ¾-inch water meter. County-approved private improvement plans incorporating the private road and engineered sewer improvements are available, potentially saving substantial time and development costs. The property enjoys a rare sense of privacy and open space with surrounding undeveloped land and nearby Eucalyptus County Park, creating a peaceful country-estate atmosphere that is increasingly difficult to find in such a central location. The neighboring residence recently sold for more than $2.3 million, further demonstrating the strength and desirability of the surrounding luxury home market. Seller has assembled an extensive due diligence package, including approved improvement plans, survey, utility information, and additional property documents, all of which are available upon request. Buyer and Buyer's Agent are advised to independently verify all information, including zoning, density, SB 9 development rights, utility availability, development standards, building requirements, and all matters affecting the property's intended use.
