Highlands Mobile Home Park in Santee is an age-restricted 55-and-older manufactured-home community established in 1973 on Mission Gorge Road at the western gateway to East County San Diego. The 306-site cooperative runs on a membership-ownership model that allows lot holders to build equity, and the community's pet-permitted policy connects residents to the Mission Gorge Road pet-supply corridor anchored by All 4 Pets. On-site amenities include a clubhouse, swimming pool, and recreational facilities spread across paved streets designed for low-speed residential traffic. The 7467 Mission Gorge Road address sits less than half a mile from the San Diego River corridor and roughly one mile from the southwestern entrance to Mission Trails Regional Park, giving the community foot-and-pedal access to the Cowles Mountain and Father Junipero Serra trail networks. Multisection homes dominate the park with floor plans typically spanning 1,200 to 1,600 square feet across two-bedroom, two-bath configurations, and the Mission Gorge Road frontage puts independent mechanics—including Import Auto Service half a mile east—within a short drive for routine vehicle maintenance. The community's infrastructure includes well water, septic sewer service, and 100-percent multisection-home sites with off-street parking pads sized for full-length vehicles and storage sheds wired for electrical service.
