Custom single-level home on nearly an acre in Atascadero featuring a spacious private guest apartment above the garage, offering exceptional flexibility for extended living, guests, or potential income. Set among mature oaks on a gently sloping lot, the property captures sweeping views across East Atascadero from nearly every room. The main residence offers 2 bedrooms and 2 bathrooms with a highly functional single-level layout, vaulted ceilings, and an abundance of natural light. The detached guest apartment is a true standout, complete with its own private entrance, parking, living area, kitchenette, bathroom, balcony access, and dedicated laundry below. Recently updated with new flooring, the space is large enough to potentially accommodate an additional bedroom while still maintaining comfortable living space, making it an ideal option for multi-generational living or added versatility. Inside the main home, the living room features cathedral ceilings, a stone-surround fireplace, expansive windows, and new flooring. The remodeled kitchen includes quartz countertops, stainless steel appliances, ample bar seating, and an adjacent dining area. The primary suite opens to a private balcony and includes a remodeled bathroom with dual sinks, a walk-in glass shower, and a freestanding soaking tub. Recently painted inside and out, the property also offers low-maintenance landscaping, front garden beds, terraced gardening areas, fruit trees including a mature Meyer lemon tree, a gazebo with spa, a shed, oversized driveway, 2-car garage, and covered carport. There is also room for future expansion, subject to city approval. Located just minutes from downtown Atascadero, approximately 10 minutes to Paso Robles, and close to shopping, restaurants, wineries, and the new Valley Fresh Market, this property offers a rare combination of privacy, usability, and convenience.
