Summit Estates is a gated community of 30 luxury single-family homes in La Mesa developed by Cornerstone Communities, the largest privately held homebuilder in San Diego County with 9,000-plus homes constructed across 90-plus California developments since 1994. Three floor plans range from 2,473 to 3,901 square feet with up to six bedrooms and five-and-a-half bathrooms, and every home includes a multi-generational suite with a private entrance — a layout requiring site grading and hardscape coordination from landscape contractors like Botanically Crafted Landscapes for each lot's private fenced backyard. Prices start at $1,378,990 under DRE license #01451200 through The Cove Realty Group. Each home ships with pre-installed solar panel arrays and two-or-three-car garages sized for La Mesa's east-county commuter patterns, and the architectural permit set feeds through design review with DesignX Architecture + Interiors for buyer-requested customization packages. Highest-specification builds include premium crest-view lots with engineered retaining walls, moment-frame steel connections, and Title 24 energy-compliance packages exceeding CalGreen baseline requirements.
