Discover distinctive urban living at Harbor Lofts, an exclusive 46-unit boutique condominium community housed in a carefully restored 19th-century warehouse in San Francisco’s vibrant South Beach neighborhood.

Historic Warehouse Architecture & Restoration
Harbor Lofts occupies the meticulously rehabilitated Hathaway Warehouse, one of San Francisco’s most significant surviving industrial buildings. The structure’s foundation dates to the mid-19th century, with the ground-level brick construction originating around 1856. Subsequent additions to the Harrison Street façade were completed in 1875, with the upper sections finished by approximately 1900. The distinctive cream-colored brick exterior features projecting hood moldings along the Spear Street frontage, with brick pilasters and corbelled capitals dividing the facade into paired window bays. This architectural detail creates the building’s signature character and historical presence.
The 1996-1997 restoration by architectural specialists transformed the warehouse into 46 residential lofts while preserving original structural integrity. Interiors showcase exposed brick walls, exposed timber beams and trusses, soaring 16 to 18-foot ceilings, and substantial windows providing abundant natural light and cross-ventilation. Units range from 650 to 1,700 square feet, accommodating studio, one-bedroom, and two-bedroom configurations. All residences feature direct access to a dramatic two-story central courtyard, creating an intimate community environment within the urban setting.
Contemporary Finishes & Premium Features

Custom renovations feature wide-plank hardwood flooring, designer lighting fixtures, custom fireplace accents, gourmet kitchen appointments with premium stainless steel appliances, marble countertops and backsplash, oversized windows showcasing city views, and spa-quality bathrooms with soaking tubs and separate shower enclosures. Corner units offer distinctive panoramic windows, while generous bedroom closets and in-unit laundry facilities add everyday convenience. The building benefits from covered parking options, a rare amenity in central San Francisco.
