Overview
This fully renovated, well-maintained property is a four-unit quadplex with approximately 5,760 square feet of heated interior space, plus deep-water access to the St. Lawrence River. The main level includes expansive commercial space spanning half of the main level, with additional commercial space nearly filling the lower level. The four residential units include a furnished 1-bedroom, 1-bath unit currently operating as an Airbnb, a 2-bedroom, 1-bath apartment with long-term tenants, and an additional 1-bedroom, 1-bath unit rented monthly to medical professionals. Each unit is heated with an efficient natural gas furnace. Recent updates completed in 2023–2024 include a new roof, updated electrical with four separate meter options, modern PEX plumbing, and new water heaters.
The property provides 85 feet of level waterfront frontage along the St. Lawrence River and includes a private dock for boating access. Paved parking is available in both the front and rear of the building, supporting tenant and customer use depending on the configuration.
The layout supports multiple operating strategies, including maintaining the current multi-unit mix, converting space between commercial and residential uses, establishing a live-work arrangement, or using the property as one large unit. Separate electric meters and the existing commercial footprint may be particularly useful for tenants or owner-operators seeking flexibility while preserving income-producing residential units.
