About This Property
Developers and multi-generational families, don't miss this rare 31+ acre mountaintop opportunity in San Marcos. Significant infrastructure is already in place, including a producing private well, water meters, electrical service with poles installed, paved access roads, multiple entry points, graded building pads, and over $1 million in seller improvements. A previous residence existed on the property, but there are currently no homes on site. Comprised of two parcels totaling over 31 acres, this private estate offers breathtaking ocean views, panoramic valley vistas, and exceptional privacy. Zoned A70 with the desirable "L" Animal Designator, the property may offer the potential for up to seven estate-sized homesites (buyer to verify). The seller is actively pursuing building plan approvals and anticipates approval soon, with septic installation planned in the near future. Whether you're envisioning a luxury estate, family compound, agricultural operation, or future development project, this property offers a rare combination of views, infrastructure, and opportunity in one of North County's most desirable rural settings.
