All-Inclusive Waterfront Living in SW Washington

The Harbour Square cooperative sits at the intersection of SW Washington’s established residential fabric and its evolving waterfront identity. Unit W602 is a one-bedroom, one-bath residence spanning 960 square feet — a footprint that accommodates comfortable living without the compromises typical of smaller urban condominiums.

What distinguishes this residence most is the scope of its monthly fee. Electricity, gas, heat, air conditioning, water, sewer, cable television, real estate taxes, insurance, parking, pool access, and reserve contributions are all included. For buyers accustomed to layering utility bills atop a mortgage, the all-in cost structure here warrants careful comparison against conventionally structured alternatives.

The Waterfront Metro station is close at hand, placing the National Mall, Capitol Hill, and the broader DC core within easy reach. The SW Waterfront — home to The Wharf development, waterfront dining, and the municipal fish market — is a short walk away, offering a concentration of dining, entertainment, and outdoor amenity that has reshaped this quadrant’s daily rhythm.

Assigned parking is included, a meaningful advantage in a city where parking often carries a separate premium or is unavailable entirely. The building’s 1966 construction reflects the mid-century planning vision that gave SW Washington its distinctive character — larger footprints, mature landscaping, and a community-oriented site plan that newer developments rarely replicate.

The Residence
Unit W602 at Harbour Square is a one-bedroom, one-bath residence measuring 960 square feet. The floor plan provides proportions that support genuine daily living — room for a dedicated dining area, a proper living space, and a bedroom that accommodates standard furnishings without compromise.
HOA Fee Structure
The monthly cooperative fee at Harbour Square is among the most comprehensive in DC. Electricity, gas, heat, air conditioning, water, sewer, cable, real estate taxes, insurance, and parking are all covered. Buyers should model the all-in monthly cost against comparable properties where utilities are paid separately.
Waterfront Location
SW Washington’s waterfront corridor has become one of the district’s most active neighborhoods. The Wharf and the historic fish market anchor a stretch of the Potomac that now draws residents and visitors alike. The Waterfront Metro station provides direct access to the broader city without a car.
Parking and Building
Harbour Square was developed in 1966 as part of SW Washington’s urban renewal era, and its site plan reflects that period’s emphasis on open space and community amenity. Assigned parking is included with this residence — a practical benefit that adds tangible value in the DC market.

Property Location

About 490 M St SW #W602

Harbour Square is a mid-century cooperative community in SW Washington, developed in 1966 as part of the neighborhood’s urban renewal era. The complex is known for its generous unit footprints, mature landscaping, and a site plan that prioritizes open space — qualities that distinguish it from more recently constructed condominium buildings in the area. Unit W602 offers 960 square feet of interior space configured as a one-bedroom, one-bath residence. Assigned parking is included, and the building provides pool and recreation facility access to residents.

SW Washington occupies a distinct position in the district — bounded by the National Mall to the north, the Anacostia River to the east, and the Potomac to the south and west. The quadrant’s residential character is anchored by its mid-century planned communities, and its public amenity has expanded significantly with The Wharf development along the waterfront. The historic SW fish market, one of the oldest continuously operating markets in the country, remains a neighborhood institution. The Waterfront Metro station connects residents directly to the Green and Yellow lines.

Daily life in SW Washington is shaped by proximity to the water and to the city’s core institutions. The Wharf provides a concentrated stretch of dining, retail, live music venues, and waterfront access that draws residents throughout the year. The National Mall is accessible by Metro or on foot, placing the Smithsonian museums, memorials, and federal buildings within easy reach. Local grocery options, neighborhood parks, and the waterfront trail system support a walkable, amenity-rich routine without requiring a car for most daily needs.

Frequently Asked Questions About This Property

Key details about the residence, building, and location to help you evaluate this opportunity.

The monthly fee at Harbour Square is among the most comprehensive in DC. It includes electricity, gas, heat, air conditioning, water, sewer, cable television, real estate taxes, building insurance, parking, pool access, recreation facilities, snow removal, trash, and reserve fund contributions. Buyers should request the current fee amount and review the cooperative’s financials before making an offer.
Harbour Square is structured as a cooperative, meaning buyers purchase shares in the corporation rather than fee-simple real estate. This distinction affects financing — not all lenders offer co-op loans — and may involve board approval of buyers. A Wardman team member can walk you through the practical implications and connect you with lenders experienced in DC cooperative transactions.
The Waterfront Metro station, served by the Green and Yellow lines, is the closest station to Harbour Square. The Green Line provides direct access to Columbia Heights, U Street, and points north, while the Yellow Line connects to Pentagon City, Alexandria, and Reagan National Airport. Both lines serve downtown DC and L’Enfant Plaza.
Assigned parking is included with this residence and is covered within the monthly cooperative fee. In DC, where parking frequently carries a separate monthly cost or is simply unavailable, this is a meaningful practical and financial benefit. Buyers should confirm the specific space assignment and any associated rules with the cooperative management.
Because the Harbour Square fee includes utilities, taxes, insurance, and parking, the true monthly cost comparison requires adding those line items to the mortgage and fee of any alternative property. A Wardman team member can model this comparison using recent SW Washington and broader DC comparables to help buyers evaluate the full picture.
SW Washington offers a walkable, waterfront-oriented daily environment. The Wharf development and the historic fish market provide dining, retail, and outdoor activity along the Potomac. The National Mall and its museums are accessible by Metro or on foot. The quadrant has a distinct mid-century residential character shaped by its planned community origins.
Harbour Square was built in 1966, and prospective buyers should review the cooperative’s reserve fund study, recent capital improvement history, and any pending assessments. A well-funded reserve is a positive indicator in a building of this age. Buyers are encouraged to engage a qualified inspector and review the cooperative’s financial disclosures thoroughly.
A Wardman team member and the Wardman Residential team at Compass have experience navigating DC’s cooperative market, including the due diligence specific to all-inclusive fee structures and board approval processes. We can provide recent comparable sales, help model true monthly costs, and guide you through the cooperative purchase process from offer to closing.
