Versatile property with significant upside potential at 20 Madison Ave in Valhalla. Currently utilized as offices but legally classified as a single-family residence, this property offers a compelling opportunity for conversion to a multi-family, subject to local approvals. Currently has month to month commercial tenants on 1st & basement and another on 2nd-3rd floors. Spanning approximately 3,300 square feet across multiple levels, the existing layout includes numerous private rooms, bathrooms, and separate workspaces—providing a strong foundation for reconfiguration. The finished basement with walk-out access and multiple entry points further enhances flexibility for a variety of layouts. The property sits on a 0.23-acre lot and includes a driveway and additional parking area. Separate electric meters are already in place, adding to the property’s potential for future use scenarios. Central air and public utilities are in place. Conveniently located near the Taconic State Pway, 2 blocks from Metro North Valhalla stop on the Harlem Line, and local amenities. Important: Property is being sold as-is. There is currently no Certificate of Occupancy, and there are three open/expired permits with the Town of Mount Pleasant. Buyer is responsible for verifying use, obtaining approvals, and resolving any outstanding permits. This is an opportunity for buyers seeking a value-add project with multiple potential end uses in a well-located Westchester setting.
