A Rare Bethesda Home with a Licensed ADU and Income Potential A rare opportunity to own a renovated detached home with a licensed accessory dwelling unit (ADU) in the heart of Bethesda. Just a short walk from downtown Bethesda, 7909 Tilbury Street offers something increasingly hard to find: a versatile property that can provide rental income, multigenerational living, guest accommodations, or additional space for your own needs. The main residence offers approximately 2,200 finished square feet across two levels, with 4 bedrooms and 2.5 baths. The renovated gourmet kitchen features quartz countertops, a large center island, and updated appliances, opening seamlessly to the dining area with views of the backyard. The main level also features a welcoming living room with fireplace and a spacious family room that connects to the dining area, creating a comfortable setting for both everyday living and entertaining. Upstairs, the generous primary suite includes a large walk-in closet and updated en-suite bath. Three additional bedrooms, a hall bath, and conveniently located laundry complete the upper level. The licensed lower-level ADU offers approximately 1000 finished square feet with its own private exterior entrance, two bedrooms, a full bath, kitchen, laundry, and living area. For buyers looking to offset their housing costs, the setup offers the opportunity to live in the main home while renting the ADU. It also provides an excellent option for extended family, guests, an au pair, or a private home office and living suite. Prefer one larger home? The lower level may offer the potential to be incorporated into the main residence through the addition of an interior staircase, creating even greater flexibility for a variety of living arrangements. Outside, enjoy a welcoming front porch, ample off-street parking, and a detached garage with electricity and water. Currently used as a recreation and sports space, the garage could easily become a home gym, studio, workshop, hobby space, or additional storage. And then there is the location. Walk to Bethesda's restaurants, shopping, entertainment, parks, Metro, and neighborhood amenities, with easy access to major commuter routes. A renovated detached home. A licensed ADU. A walkable Bethesda location. And the flexibility to create rental income or space for the people and priorities that matter most.
