Commercial Property for sale in East Setauket, NY

for $1,500,000. This 15,000 square foot building was built on a lot size of 1.5.

Rare opportunity to acquire a unique property in the heart of historic Setauket within the Town of Brookhaven, Suffolk County, NY. Situated on an expansive parcel within the A-1 Residence District, the property offers a distinctive combination of existing improvements and potential future uses, subject to town approvals. The site is improved with a main church building along with several additional structures. An auxiliary residential building containing four bedrooms historically supported the church’s operations. A second residential structure fronting Main Street, previously used as a monastery, is currently vacant. The property also contains several smaller free-standing structures that appear to be used for storage purposes. The generous lot size and prominent Main Street location present a compelling opportunity for a variety of potential uses including continued institutional use, residential conversion, or possible redevelopment, subject to zoning regulations and approvals from the Town of Brookhaven. With substantial site area and frontage along Main Street, the property offers a scale that is rarely available in the historic Setauket area. The depth of the parcel and the presence of multiple existing structures may provide flexibility for estate-style residential use, adaptive reuse, or other redevelopment concepts, subject to Town of Brookhaven zoning regulations and approvals. Properties with this combination of land size, location, and existing infrastructure are seldom offered in this established North Shore community. Ideally located within the highly regarded Three Village School District and just minutes from Stony Brook University, Stony Brook Hospital, Port Jefferson Village, and the Long Island Sound, the property benefits from strong surrounding home values and a desirable North Shore setting. Buyers are encouraged to perform their own due diligence regarding zoning, permitted uses, and potential subdivision or redevelopment opportunities.
