A 4-bedroom, 4-bathroom single-level estate with an income-producing 1-bed/1-bath ADU - 4,260 sq. ft. on 2.65 private acres in Fallbrook, CA 92028, built in 1992 and served by a newly installed Cambridge elevator - delivers rare main-floor living with no stairs required and a self-contained dual living unit on the same footprint. For buyers weighing a move from Los Angeles, Orange County, or the Bay Area, this gated estate in North County San Diego checks every box: land ownership, agricultural income, energy independence, and a sub-two-hour drive back to the city when you need it. Positioned to capture sweeping hillside views in one of San Diego County's most sought-after rural enclaves, the main living floor features Italian tile flooring, quartz countertops, and a chef's kitchen with Viking appliances and a wine refrigerator; every bedroom includes both a walk-in and slider closet, and the 4-car garage adds four private walk-in storage rooms plus parking for trailers, boats, or RVs - practical details that suit the rural lifestyle Fallbrook has cultivated for generations. The home's open layout and high-speed infrastructure make it equally capable as a primary residence or a full-time remote work headquarters; you can run a home office, take calls from the terrace, or simply disconnect entirely - the property is built for all three. A dedicated home-office suite pairs naturally with the avocado ranch setting, giving remote-work buyers a San Diego County address without sacrificing space or productivity. The Cambridge elevator supports true aging-in-place living across the single-level floor plan, future-proofing the investment for multigenerational households. The attached 1-bed/1-bath ADU (~500 sq. ft.) has its own full kitchen and living area, purpose-built for caregiver quarters or extended-family use and fully capable of functioning as an income property (subject to local regulations) - a meaningful offset in a market where dual living flexibility drives purchase decisions. The 2.65 fully fenced acres support a working avocado grove of 100+ fruit trees - approximately 80 to 85 avocado - making this a genuine agricultural property eligible to explore Williamson Act or similar agricultural classifications; the orchard distinguishes this listing from every conventional estate in North County San Diego. The land is backed by a new well system with a variable-speed motor installed in 2023, and a 48-panel fully owned solar system with battery storage delivers the kind of energy independence that makes near off-grid capable living a real option year-round. The solar array, battery bank, and private well together push utility costs well below what comparable San Diego County properties carry. The I-15 corridor places you 35 minutes from downtown San Diego, 45 miles from San Clemente and the Orange County coast, approximately 85 miles from downtown Los Angeles, and just 30 minutes from the beaches at Oceanside and Carlsbad - you can drive to the coast for lunch and be back among the avocado ranch rows by afternoon. Fallbrook itself carries an equestrian heritage unlike anywhere else in the region; horse property buyers will find the acreage, fencing, and rural character consistent with that tradition, and the property's setting earns the town's long-held nickname as "The Friendly Village." The property sits inside Rolling Hills Estates, Fallbrook's only 24/7 guard-gated community, with tennis courts, a clubhouse, and an HOA of $550/month. Served by Fallbrook Street Elementary, James E. Potter Intermediate, Fallbrook High School, and the Fallbrook Union Elementary and Fallbrook Union High School Districts. Private showings available by appointment.
