The Mariner Condominium

The Mariner Condominium is a low-rise, converted waterfront condominium originally built in 1900 and reconfigured into residences in 1987. The property reads as a singular block-like structure with a distinctive ship-inspired exterior along Commercial Street on Boston’s Harbor. It contains just over 100 residences primarily configured as one-bedroom and studio plans, with occasional larger corner units and penthouses offering wraparound terraces. Typical interiors feature high ceilings, hardwood or parquet floors, generous windows that maximize harbor and city vistas, and a mix of renovated kitchens with stone counters and in-unit laundry in many homes. Building services and shared areas include a staffed 24-hour concierge, on-site management, a prominent common roof deck with panoramic harbor and skyline views, and deeded or rentable garage parking. Exterior amenities emphasize private outdoor space: many units have balconies, private decks, or access to roof terraces; the property also provides storage and enclosed patios for select residences. Practical building infrastructure includes elevator service, wired sound systems in some homes, high-speed internet availability, and thoughtful storage/linen spaces. Located steps from the North End, Faneuil Hall and the Financial District, the Mariner combines a historic waterfront address with urban convenience, promenades and immediate transit connections. Pet policies and parking vary by unit but the building historically accommodates pets and offers underground garage options.
