Boston, MA office market
Office space in Back Bay.
Back Bay extends from Arlington Street west to Massachusetts Avenue, anchored by the Prudential Tower, 200 Clarendon (Hancock Tower), and the Copley Place / Prudential Center retail complex. Inventory is ~25 million square feet. Asking rents run $65–$90/SF on Class A, with the Prudential and Hancock towers commanding $80–$110/SF on top floors. Availability is in the mid-teens — among the tightest of any major-city submarket in the post-COVID environment.
Back Bay's resilience comes from its tenant mix. Anchored by life sciences (the Boston/Cambridge corridor is the global biotech capital), top-tier law (Ropes & Gray, WilmerHale, Foley Hoag), management consulting (BCG, Bain, McKinsey Boston), and asset management (MFS, State Street satellite). These industries returned to office faster than average and continued absorbing space through 2023–2025 while peer markets softened.
The trophy stock is concentrated. The Prudential Tower (52 floors, 1.2M SF), 200 Clarendon (Hancock Tower, 60 floors, 1.7M SF), and One Boston Place form the Class A core. Beyond those three, Back Bay Class A is mostly mid-rise (10–20 stories) along Boylston and Newbury — attractive build quality but with smaller floor plates (12,000–20,000 SF common).
Tenants comparing Back Bay to the Seaport (Boston's other major submarket) face a clear tradeoff. Back Bay is more expensive ($10–$20/SF Class A premium), more established, and has a denser amenity stack. Seaport is newer, water-adjacent, lower-density, and has more available large blocks for full-floor tenants. For 5,000–15,000 SF tenants Back Bay typically wins; for 30,000+ SF tenants Seaport often delivers better value.

Broker perspective
Back Bay is one of the few major-city submarkets where I'd describe the leasing environment as still favoring landlords on trophy product. Free rent and TI are negotiable but compressed vs. peer markets — 8–12 months free rent and $80–$120/SF TI on a 7-year deal is realistic. Tenants who try to extract Manhattan-grade concessions here will lose deals to competing tenants. Set expectations accordingly.
Frequently asked
People also ask
Why is Back Bay so resilient post-COVID?
Tenant mix — life sciences, top-tier law, consulting, and asset management all returned to office faster and continued absorbing space. Combined with limited new supply (Boston builds slowly), the demand-supply balance has stayed in the landlord's favor.
Should I lease in Back Bay or Seaport?
Back Bay if you're under 15,000 SF, value the established neighborhood and amenity stack, and can absorb a $10–$20/SF premium. Seaport if you're over 30,000 SF, want larger floor plates with newer construction, and are happy with the waterfront-but-emerging neighborhood feel.
What's typical lease term in Back Bay?
7–10 years on Class A. Boston tenants tend to take longer terms than coastal peers because of high build-out costs and slower market change. 5-year terms are negotiable but landlords reduce concessions accordingly.
Is Back Bay more expensive than Cambridge?
Different markets. Cambridge / Kendall Square is the life-sciences capital with $90–$130/SF lab/office hybrid pricing. Back Bay is generalist Class A office at $65–$90/SF. They're not direct substitutes; tenants pick based on whether they need wet-lab capability.
