Just 800 feet from Keyes Memorial Beach and .7 sidewalked miles to Main Street Hyannis, 388 Sea Street is a rare coastal compound with scale, flexibility, and proven rental appeal. Set on .45 acres with two driveways and ample parking, the extensively renovated property offers approximately 4,525 sf, 9 bedrooms, and 8.5 baths across several distinct living areas: a 6 bedroom, 4.5 bath main home with an attached 2 bedroom, 2 bath guest suite, a private studio with bath, and a separate two-car garage with a 1 bedroom, 1 bath apartment above. Currently used as a successful blend of vacation and year-round rental housing, the property holds a Town of Barnstable lodging house license allowing up to 10 individual rental rooms and 20 people on site. Residential Congregate Housing zoning further supports potential inn, bed and breakfast, or flexible income-producing use. A compelling Hyannis offering near beach, downtown, harbor, ferries, restaurants, and Cape Cod summer energy.
