25770 E GRADE ROAD, Santa Ysabel, CA 92070

11+ Acres in San Diego County's most coveted mountain range, Palomar Mountain. NO STR restrictions. Short-term rentals permitted. | Set within the quiet valley between Palomar Mountain and Lake Henshaw, this 11+ acre property offers a rare expression of mountain living in San Diego County.

Located along the eastern slope of Palomar and surrounded by the protected landscapes of Cleveland National Forest and the San Jose Valley watershed, the setting feels deeply removed from the pace of coastal life while remaining within reach of North County communities.

This region is known for something increasingly rare in San Diego: true seasonal change. Spring brings wildflower-covered meadows and migrating birds across the valley. Summer days are warm but tempered by elevation. Autumn arrives with golden oak canopies and crisp mountain air.

In winter, occasional snowfall transforms the surrounding peaks of Hot Springs Mountain and Palomar into a quiet alpine landscape. The residence itself was designed as an artist’s retreat—an off-grid sanctuary where architecture and landscape remain in quiet conversation.

Spanning approximately 2,150 square feet, the home is framed by open meadow and distant ridgelines overlooking the Lake Henshaw Basin. A wraparound patio invites daily life outdoors, where morning light moves across the valley and evenings settle into expansive starlit skies.

Inside, vaulted ceilings and classic Post & Beam architecture create a warm, open interior anchored by a brick-lined fireplace with soapstone wood stove. Newly refinished red oak floors run throughout the main living spaces, while the kitchen has been thoughtfully updated with warm wood finishes and curated lighting designed for gathering.

The primary suite offers a peaceful vantage point over the surrounding landscape with a walk-in closet and reading nook. A second primary bedroom in the finished lower level includes its own entrance, den, and access to the one-car garage, creating flexible space for guests, studio work, or extended stays.

A loft conversion offers potential for a third bedroom. Designed for true off-grid living, the property includes a private well and a temperature-controlled solar power house supporting the home’s independent energy system. In late 2025, the system was significantly upgraded with approximately $45,000 in new solar infrastructure, further strengthening the property’s long-term efficiency and reliability.

Outdoors, groves of Coast Live Oaks shelter local wildlife while open meadowland offers room to roam. Direct trail access leads into Love Valley, a historic equestrian community known for its riding culture and extensive horse trails. From the property, riders can access miles of backcountry terrain without loading a trailer.

Beyond the property, the surrounding region offers a lifestyle defined by nature and quiet exploration. Hiking and mountain biking trails wind through Cleveland National Forest. Fishing and boating await at nearby Lake Henshaw. The historic towns of Santa Ysabel and Julian provide local markets, bakeries, and small-town gathering places.

Palomar Mountain’s general store and post office remain a reminder of the area’s rural heritage. Despite its sense of seclusion, the property remains connected. Valley Center and Escondido are roughly 50 minutes away, offering convenient access to North County amenities while preserving the rare tranquility of San Diego’s mountain backcountry.

For those seeking space, silence, and a deeper relationship with the land, this property offers an uncommon opportunity to live within one of Southern California’s most quietly extraordinary landscapes. Shown by appointment only. Property is occupied.
