Welcome to Harbour Square

A Cooperative Community on Washington D.C.’s Southwest Waterfront

Harbour Square Owners, Inc., is a historic cooperative in a beautiful setting along the Washington Channel. Panoramic views of the Potomac River, complemented by beautifully landscaped gardens and large reflecting pools, offer residents a calm oasis in the nation’s capital.

Our community includes more than 440 residences, ranging from comfortable efficiencies to three-bedroom units, many with fireplaces, garden patios and balconies with exquisite views. We also have townhomes, some of which date back to the 1790’s and are listed in the National Register of Historic Places.

Harbour Square offers perfect combinations of land and sea, historic and modern, serenity and vibrancy — all in an incredible metropolitan location. It is the perfect place to call home.
