This expansive commercial property sits prominently on Main Street in the heart of downtown Calais, extending all the way through to the next street - a rare and valuable footprint in the city center. With its commanding presence, generous square footage, and flexible layout, this building presents a one-of-a-kind opportunity for investors, developers, or business owners seeking visibility and growth. The property features two large street-level storefronts, each with its own entrance and oversized display windows capturing attention of steady pedestrian and vehicle traffic. One space is rented by a well known resale shop and both remain perfectly suited for a wide variety of retail, dining, or service-oriented businesses. On the second floor, remnants of the building's history remain - former offices with touches of historic character that could be reimagined into modern workspace or boutique-style professional suites. Behind the Main Street frontage, additional space unfolds, providing more room for expansion, storage, or adaptive reuse. These spaces once housed a well-known restaurant and a popular fitness studio, and they remain perfectly suited for a wide variety of retail, dining, or service-oriented businesses. A standout feature of this property is its connection to the city-owned parking lot at the rear, offering easy access for tenants and customers - a true advantage in the downtown market. Above the rear commercial section, an unfinished upper level awaits a visionary touch. With the right plan, this expansive area could be transformed into multiple apartments. The broad square footage, and flexible layout create the perfect canvas for a mixed-use redevelopment under one roof. Whether your vision is to revitalize the commercial storefronts, restore the second-floor character, or unlock the potential of residential living space above, this property offers the scale, location, and history to make it an anchor in the ongoing renewal of downtown Calais.
