Renting Commercial Office Space in Seaport District
The Seaport remains Boston’s most resilient commercial submarket, characterized by the city’s newest and highest-quality Class A inventory. A landmark milestone for early 2026 is the full operational stabilization of 400 Summer Street, where toy giant Hasbro recently filled 265,000 square feet after relocating its headquarters from Rhode Island (Source: CoStar Analytics, Dec 2025). The Seaport has solidified its status as the city's primary "Live-Work-Play" destination. With the market favoring trophy assets, the Seaport is expected to maintain some of the lowest vacancy rates in the city. Investors are targeting the submarket for its high concentration of blue-chip life sciences and tech firms, though rental premiums for quality space are projected to rise as new supply slows down (Source: Cushman & Wakefield 2026 Forecast).
