245 Summer Street, Boston

Quick answer: 245 Summer Street, Boston, MA 02210 is a 14-story office building next to South Station. It has been Fidelity Investments’ corporate headquarters address since 2012. In 2026, Fidelity opened a new campus at Commonwealth Pier in the Seaport, but said it would keep its Summer Street office, so the building remains in use.

The address gets searched by people who want a mailing address, a location, a bit of history, or a status check. Some directory pages still describe the building without mentioning the 2026 changes, so this guide covers the facts and the update. Everything is current as of October 2026.

Where Is 245 Summer Street in Boston?

The building is at the edge of downtown Boston, close to the Fort Point area. It is next to South Station, one of the region’s major transportation hubs. In practice, that makes it one of the more reachable large office addresses in the city for people arriving by rail or transit.

Two details are worth knowing:

• Neighborhood framing. Reports describe it as near South Station and Fort Point Channel. It is not in the Seaport, although Fidelity’s newer campus is.
• Distance to the new campus. The Boston Globe describes Fidelity’s Commonwealth Pier complex as nearly a mile away from the Summer Street headquarters.

I could not verify current parking arrangements or building-specific access rules, so check official sources before planning a trip.

Is 245 Summer Street Fidelity’s Headquarters?

Yes. It is Fidelity’s long-standing headquarters address, and it is still in use. The picture has two parts.

How Fidelity Came to Occupy the Building

Fidelity has a long history here. It moved into 245 Summer St. in 1999 after acquiring the property. The building became the company’s official headquarters later. In 2012 Fidelity announced it would move its Boston headquarters to 245 Summer St. and eventually vacate 82 Devonshire St. At that point, about 2,900 employees already worked at Summer Street.

What Changed in 2026

Fidelity built a new campus at Commonwealth Pier in the Seaport, the redeveloped former Seaport World Trade Center. For a time, it planned to leave Summer Street. In 2025, Fidelity put its 803,000 sq ft of space at 245 Summer St. up for sublease.

Then the plan changed. Fidelity said in April 2026 that it would maintain its main corporate office at 245 Summer Street while moving workers to Commonwealth Pier. The Globe reported that the company needed more space for workers after announcing a five-day office requirement.

By September the new campus was open. Fidelity began requiring its 6,000-plus Boston-based employees to work in person five days a week, with many returning to the new Seaport headquarters.

The official designation is still developing. Fidelity told the Boston Business Journal that it plans to file paperwork naming Commonwealth Pier its new headquarters, without giving a timeline. I found no confirmation that the filing has been made. For now, a precise way to put it is that 245 Summer Street remains a major Fidelity office and has been its headquarters address since 2012, and Commonwealth Pier is becoming the company’s new headquarters campus.

The Building’s History and Ownership

The ownership story is a useful reminder that a tenant and an owner are not always the same:

Year	Event
1974	Building completed
1999	Fidelity moves in after acquiring the property
2004	Fidelity sells to Benderson Development and leases the space back
2012	Fidelity formally makes it the corporate headquarters
2020	A Fidelity affiliate buys the building back
2025	Fidelity lists its space for sublease
2026	Fidelity keeps the building and opens Commonwealth Pier

The financial details come from Banker & Tradesman. Fidelity sold the property to Benderson in 2004 for $307 million and leased the space back. An affiliate, Horizon Real Estate Investors, reacquired it for $728.5 million, and Fidelity signed a 20-year lease for the entire building. That 2020 price was just over $800 per square foot.

Sources differ slightly on some earlier details, such as which street Fidelity’s prior headquarters was on. The 2012 reporting from Boston.com identifies 82 Devonshire Street, which is the version used here.

Fidelity in Boston Today

Fidelity is a very large private financial services company. Wikipedia lists about 80,000 employees worldwide in 2025, revenue of $37.7 billion, and assets under management of $7.1 trillion. Older directory pages cite lower employee counts, so use current figures if you reference company size.

Boston is one of its largest hubs. The 6,000-plus local workforce figure above matters for the surrounding area. Reporting from WBUR noted that the five-day office requirement was expected to benefit nearby businesses such as lunch spots and barbershops.

245 Summer Street vs. 245 Sumner Street (East Boston)

These are different addresses and different properties:

• 245 Summer Street is the downtown office tower described above.
• 245 Sumner Street is a newly built rental apartment property in East Boston, according to its own website, which lists two- and three-bedroom units near Maverick Square.

The names differ by one letter, and people searching for one sometimes land on the other. If you are looking for Fidelity, you want Summer with a double “m.”

Visiting or Contacting Fidelity

245 Summer Street is a corporate office, not a public attraction. I could not verify a public visitor policy, so do not assume you can walk in. Practical steps:

1. For account help, branch locations, or contact options, use Fidelity’s official website at fidelity.com.
2. For business correspondence, confirm the correct department and mailing address with Fidelity before sending anything.
3. Do not rely on third-party directory listings for current details. Some of those pages carry generic or outdated descriptions.

Why HQ Addresses Matter for Sales Research

Sales teams routinely use headquarters addresses to build account lists and territories. This address shows why that data goes stale. One company can have an official headquarters, a historic headquarters address, and multiple large offices at the same time. When you build or enrich account data:

• Check the date on any directory listing.
• Compare it against recent news or official company sources.
• Record separate fields for headquarters, major offices, and mailing addresses where your tools allow it.
