Opportunity awaits at 20 Madison Ave, a legal single-family Colonial offering over 3,300 square feet of interior space on a 0.23-acre lot in Mount Pleasant. Currently configured as office space, legal 4 bed 1 bath, this property presents a unique chance to restore and customize a residential layout to suit your vision. Currently has month to month commercial tenants on 1st & basement and another on 2nd-3rd floors.
The existing layout spans multiple levels and includes numerous finished rooms, providing flexibility for reconfiguration into a traditional single-family residence with multiple bedrooms, living areas, and workspace options. A full finished basement with walk-out access adds additional usable space, while the expansive lot offers room for outdoor enjoyment, parking, or future enhancements.
The property features central air, public utilities, and a driveway with an 8-car parking lot. Conveniently located near the Taconic State Pway, 2 blocks from Metro North Valhalla stop on the Harlem Line, and local amenities, the location supports a variety of residential living needs.
Important: Property is being sold as-is. There is currently no Certificate of Occupancy, and the Town reports three open/expired permits. Buyer is responsible for all due diligence, permits, and any required approvals. A rare opportunity to bring new life to a property with strong fundamentals, generous space, and long-term potential.
