Marcus & Millichap is pleased to present for immediate sale 6 Griffin Road, a mission-critical United States Postal Service (USPS) Northeast Area Operations administrative facility. Since 1990, USPS has operated regional functions for much of the Northeast from this location. In December 2025, the tenant executed an early lease extension through 2031, with options to extend for 10 years or more, ensuring its long-term presence in the building. As part of the extension the owner will be completing over $300,000 in building renovations. This two-story building includes 257 private parking spaces and one elevator. Divided into two wings the building is easily configured to be subdivided for four separate tenants, or for redevelopment as multi-family. The property is located within a major business park, 12 miles from Downtown Hartford. This park includes 375,616 SF of office space and is home to major companies including The Hartford and Cigna. A redevelopment of several buildings in the park is expected to create 200+ multifamily units of housing, creating a live/work environment that is hard to find in the Hartford market. The pro-active Windsor Government has been a leader in pushing new zoning that will allow widespread conversions of vacant office to residential and potentially industrial uses, further enhancing the value of the occupied properties.
