Homes of this caliber seldom come to market. Located in one of Yucaipa's most desirable custom-home neighborhoods known for its quiet streets and elevated views, this 3,077 sq ft residence delivers the quality, space, and design buyers expect at the top of the market. The great room is warm and inviting, anchored by a beautiful fireplace and flowing seamlessly into the entertainer's kitchen - the perfect setting for gatherings, celebrations, and everyday living. Two full primary suites provide exceptional versatility for multi-generational families, long-term guests, or private quarters for aging parents. The main suite features dual walk-in closets and a spacious bath, offering everyday luxury. Purpose-built accessibility upgrades include 36-inch doorways throughout, no interior thresholds, a wheel-in shower, and a whole-house fan system - features rarely found together and costly to add later. Outside, a large, covered patio captures mountain mornings, golden evening skies, and sweeping views. The expansive lot offers privacy, space, and rare functionality with gated RV parking on both sides, including full hookups (50-amp, water, sewer) on the west side and additional hookups on the east. A 2-car-attached garage and wide side yards complete the layout.
