Down the hall is a freshly updated bath with new counter, mirror & shower enclosure & an extra-large laundry room for added utility & storage.

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!
