453 E 3975 S Welcome to this stunning 2019-built residence, situated in a quiet cul-de-sac on a generous .31-acre lot in Washington. This home offers a professionally designed attached Accessory Dwelling Unit (ADU) added in 2022. The ADU functions as a complete secondary residence with its own kitchen, living area, bedroom, walk-in closet and bathroom with both a tub and walk-in shower, and its own dedicated washer and dryer. While it cannot be used as a short-term rental, it is ideal for long-term rentals (30+ days), as a mother-in-law suite, or a private guest wing. There is no HOA or CC&Rs for this home. The main home boasts new hardwood flooring throughout the main level and primary bedroom, complemented by fresh paint touch-ups. In the backyard, kids will enjoy the in-ground trampoline, trees, and a sidewalk path that circles the yard. Power is already in place for a hot tub on the back patio. The home is equipped with Gemstone permanent architectural and holiday lighting, allowing you to celebrate any occasion. This rare property combines modern finishes, income potential, and a park-like backyard in one of Washington's most desirable areas.
