We’re glad you are considering living at Harbour Square. Harbour Square Owners, Inc. is a majority owner-occupied housing cooperative. Purchasing a cooperative unit is very similar to purchasing a single-family house or a condominium unit; still, cooperative living has some significant differences.

Harbour Square offers gracious living at a competitive price. When comparing costs to other properties, remember that not all condo/co-op fees are alike. Condo fees do not include property taxes, and some condo and co-op fees do not include all utilities. Be sure you know what is and is not included in the fee to help you decide whether the fee is reasonable.

At Harbour Square, the co-op fee includes:

  • Property taxes

  • All utilities

  • Internet and cable TV

  • Trash and recycling, including periodic bulk trash removal

  • Storage lockers for apartment units

  • Annual preventive maintenance on in-unit HVAC

  • Indoor swimming pool

  • Fitness center

  • Other amenities

We look forward to welcoming you to Harbour Square!


Harbour Square boasts over 140 different floor plans, each with unique features and views.


All 447 units have generous square footage and plenty of closets, reflecting its innovative mid-century modern design. Top-floor units often include private roof decks, and all townhouses and some first-floor units have private patios. This site provides typical floor plans reflecting the original architecture. Some units retain the original features, while other units have been completely reconfigured. Harbour Square offers endless possibilities to make your unit your own.

The property map shows the two 9-floor towers, mid-rise buildings, and townhomes that comprise the 8-acre complex.
