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.

ADU Potential

Massachusetts allows one accessory dwelling unit by right in single-family zoning districts statewide (M.G.L. c. 40A §3; 760 CMR 71.00, effective Feb 2025). Estimated maximum ADU size for this property: 900 sq ft (the lesser of 900 sq ft or half the 4,525 sq ft principal dwelling). Lot size: 19,602 sq ft.

Based on listing data, which indicates the property type — not the zoning district. Local dimensional, septic (Title 5), and historic-district requirements still apply. Not legal advice — verify with the municipality.
