The Packer Building
One of Mystic’s most recognizable professional buildings, The Packer Building offers historic character, flexible suite sizes, enduring tenant loyalty, and a true downtown Mystic address. From incubator-style suites around 150 square feet to larger long-term occupancies exceeding 3,000 square feet, the building continues to serve a diverse and evolving business community.
A building with a real story
The Packer Building is more than just office space. It is a long-standing part of Mystic’s commercial fabric — a property with real history, architectural identity, and a business community that has developed over decades. Built in 1902 and later repositioned into a multi-tenant office environment, the building has continued to evolve while preserving the brick, scale, and character that make it distinct.
Over time, The Packer Building has become home to an unusually broad mix of users, including financial services, legal professionals, medical and wellness operators, counselors, therapists, consultants, creative businesses, and regional service providers. This diversity is one of the reasons the building remains so resilient.
It is also one of the reasons availability is constantly changing. With more than 40 tenants and a wide range of suite sizes, the building naturally creates opportunities as tenants expand, contract, relocate, or reconfigure. That makes this page important: it serves as a central place to tell the story of the building and to help potential tenants understand the type of opportunity that may exist now or in the future.
Why The Packer Building continues to work
Flexibility across tenant sizes
The building accommodates a wide range of users. Smaller suites help support solo professionals, startups, counselors, advisors, and boutique firms looking for a prestigious Mystic location without leasing more space than they need. Larger suites provide opportunities for established businesses that want identity, functionality, and a long-term home.
A true tenant ecosystem
This is not an empty shell waiting to be filled. The Packer Building already has a living business ecosystem, and that matters. New tenants are entering a building with momentum, daily activity, and a strong professional environment rather than trying to create one from scratch.
Long-term tenancy says a lot
One of the clearest indicators of the building’s quality is tenant longevity. While many occupancies renew on shorter cycles, a number of tenants have remained in the building for years and in some cases decades. M&T Bank has been in the building since 1988. That kind of stability is not accidental. It reflects the property’s location, functionality, and staying power.
Historic character with practical infrastructure
Tenants benefit from an experience that is hard to duplicate in newer commodity office buildings: exposed brick, architectural texture, memorable common areas, and a strong sense of place, combined with practical features like two separate elevators and a layout that supports a multi-tenant environment.

Inside The Packer Building
Leasing opportunities
Because The Packer Building serves such a broad tenant base, available space is rarely static. Some opportunities may be ideal for a single practitioner or small business looking for a polished professional setting. Others may serve larger tenants looking for a more significant Mystic presence. If your business values identity, flexibility, and being part of an established business environment, The Packer Building deserves a serious look.

Approximately 150 SF and up. Ideal for counselors, therapists, consultants, attorneys, advisors, and solo professionals who want a highly recognizable Mystic address in a professional setting.
Mid-Size Opportunities
Strong fit for growing firms needing a mix of private offices, administrative space, reception, or collaborative workspace. These suites often provide flexibility for a range of office and service uses.

The building’s mix of tenant sizes and industries helps create steady activity without sacrificing professionalism. It is one of the rare properties where smaller users and more established regional occupiers can coexist naturally.
Why tenant longevity matters
On paper, some occupancies may look short-term because they renew periodically. In reality, many tenants have been in the building for years, and some for decades. That is a critical distinction. Long-term occupancy in a multi-tenant building is a sign that businesses find real value in the location, layout, economics, and identity of the property.
The fact that M&T Bank has been in the building since 1988 is one of the clearest examples. The Packer Building is not a transient environment. It is a place where businesses often stay because it works.
Why Mystic matters
The Packer Building’s value is not just tied to its square footage or layout. A meaningful part of its appeal comes from its location in the heart of Mystic — one of the most recognizable and desirable coastal business environments in New England.
Tenants benefit from proximity to downtown restaurants, boutiques, waterfront attractions, and key regional access routes, while also enjoying the identity that comes with a true Mystic address. For clients, employees, and business owners alike, that matters.
For smaller users, the location creates credibility and presence. For larger tenants, it supports recruitment, client experience, and long-term visibility. The address itself is part of the offering.
