This beautifully updated, 3 bed, 2 bath, 1372 sq ft, 1940s bungalow with detached 2 bed, 1 bath, 710 sq ft Guesthouse/ADU (without permits), & separate 2-car garage, sits in a quiet residential neighborhood in the heart of Valley Glen. Lots of possibilities! Blending vintage appeal & modern convenience, the house boasts a newer AC, raised foundation, hardwood floors, decorative wood siding, & covered front porch, while a wide driveway with an RV/car gate provides access to the detached 2-car garage. Enter directly into a spacious, light-filled living room with a large picture window. A graceful archway connects the living & dining area seamlessly. The kitchen boasts a sleek, black & white aesthetic with recessed lighting, tile floors, white cabinets, a white tile backsplash, black granite counters, black appliances, & back door leading to the yard. Down the hall is a freshly updated ¾ bath with new counter, mirror & shower enclosure & an extra-large laundry room for added utility & storage. Two good-sized bedrooms share the hall bath while a sizable primary suite has brand new carpet, as well as dual walk-in closets, a glass slider to the yard, & an en-suite bath with new flooring, mirror, light fixture, counter, & faucet. Storage abounds throughout the house with closets, linen cabinets, a pantry, & the garage, making the most of the space! The spacious backyard includes several patio areas, walkways, a lawn, a mature shade tree, & abundant fruit trees allowing you to take advantage of fresh produce, better than a farmer’s market, just out your back door. A detached guest house adds versatility with an open-concept great room combining kitchen, dining, & living areas. The two guesthouse bedrooms both have mirrored closets & ceiling fans & share access to a full hall bath. The guest house has its own heater, AC, water heater, & storage shed, making it a perfect space as an ADU or casita, studio space, a home office, gym, or really, whatever you can imagine. A detached 2-car garage provides space for parking & storage. Take advantage of the R2 zoning in the area to further develop the property, utilize the existing guest house, or convert the detached garage to an additional ADU space, all to add additional means of income to the property. The home is well situated near to shopping, dining, entertainment, recreation, & major transportation routes. Don’t miss the opportunity to tailor the space to suit your needs & make this your new home!

Pros & Cons

Pros

High Available Lot Utilization: The property has a large lot size, which is more than 4 times of its living area. lot size in square feet = 8101, living area = 1372.
Versatile Guesthouse/ADU: The property includes a detached 2-bedroom, 1-bath, 710 sq ft guesthouse with its own AC, heater, and water heater, offering significant flexibility for multi-generational living, rental income, or dedicated workspace.
Income & Development Potential: R2 zoning provides opportunities for further property development, conversion of the detached 2-car garage into an additional ADU, and leveraging the existing guesthouse for substantial rental income.
Recent Updates & Modern Conveniences: The main house features a newer AC, raised foundation, hardwood floors, and recently updated bathrooms and primary suite, blending vintage charm with contemporary comfort.
Spacious & Productive Backyard: The large backyard offers multiple patio areas, a lawn, a mature shade tree, and abundant fruit trees, providing excellent outdoor living space and fresh produce.
Desirable Location: Situated in a quiet residential neighborhood in Valley Glen, the home is well-located near shopping, dining, entertainment, recreation, and major transportation routes.

Cons

Unpermitted Guesthouse/ADU: The guesthouse/ADU is explicitly stated as 'without permits,' which presents legal risks, potential for fines, and may require significant investment to bring it up to code or legalize, potentially impacting financing and resale.
Age of Main Structure: Built in 1944, despite updates, the primary residence's age could imply potential for older infrastructure (e.g., plumbing, electrical) not explicitly mentioned as fully replaced, leading to future maintenance concerns.
Modest Main House Square Footage: At 1372 sq ft for the main house, some buyers might find the living space relatively modest for a 3-bedroom home, especially if they are not fully integrating the detached guesthouse into their primary living needs.
