A Once-in-a-Generation Hudson River Waterfront Opportunity Positioned directly on the Hudson River within Sleepy Hollow's coveted Riverfront Development District (RDD), 42 River Street represents one of the rarest commercial real estate opportunities currently available in Westchester County. Offering approximately 6,670 square feet across two levels on a 0.28-acre waterfront parcel, the property combines immediate usability with extraordinary long-term upside in a location experiencing one of the most significant redevelopment cycles in the New York metropolitan area. Unlike most commercial properties, 42 River Street benefits from something that cannot be replicated: permanent, unobstructed Hudson River and Mario M. Cuomo Bridge views, immediate adjacency to the transformative Edge-on-Hudson master-planned community, and direct exposure to a rapidly expanding population of affluent residents seeking dining, entertainment, wellness, retail, and lifestyle amenities. As the surrounding neighborhood continues its evolution into one of Westchester's premier waterfront destinations, the value proposition of this asset becomes increasingly compelling. The property sits at the doorstep of Edge-on-Hudson, the former General Motors campus redevelopment that has already transformed nearly 70 acres of industrial land into a vibrant mixed-use waterfront community. More than 1,100 residential units have already been delivered or sold, including luxury condominiums, townhomes, and apartments that command some of the highest residential pricing in the region. The recent opening of the 50,000-square-foot DeCicco & Sons flagship market, complete with rooftop dining and entertainment offerings, has further cemented the area as a destination rather than simply a residential neighborhood. What makes this opportunity particularly attractive is that the growth story is still unfolding. Additional residential phases, retail components, medical office development, hospitality projects, public parks, and RiverWalk expansions remain in the pipeline through 2026 and beyond. Every new residential unit, every new amenity, and every public improvement expands the property's customer base and strengthens its strategic position within the waterfront corridor. From an operational perspective, the building offers exceptional flexibility. The ground floor consists of approximately 3,700 square feet of warehouse and flex space with a 10-foot by 13-foot drive-in door, making it ideal for owner-users, contractors, specialty trades, artisans, distribution operations, showrooms, experiential retail concepts, breweries, fitness operators, or creative production uses. The second-floor loft space, comprising approximately 3,000 square feet, enjoys panoramic river views rarely found in commercial assets at this price point and could support office, hospitality, gallery, studio, wellness, restaurant, event, or creative workspace uses. The true value driver, however, is the Riverfront Development District zoning. The RDD designation provides a broad framework for mixed-use and waterfront-oriented development, allowing a future owner to capitalize on changing market conditions over time. Potential uses include restaurants, breweries, wine bars, galleries, health clubs, studios, boutique hospitality concepts, showroom space, mixed-use redevelopment, loft residential conversion opportunities, and a wide range of commercial applications. Few properties in Westchester offer this combination of zoning flexibility, waterfront location, and immediate access to an affluent customer base. For investors, the property presents an opportunity to acquire a scarce waterfront asset in the early stages of a long-term neighborhood appreciation cycle. For developers, it offers a strategic foothold adjacent to one of the most successful redevelopment projects in the Hudson Valley. For hospitality operators, restaurateurs, brewers, and experiential retailers, it delivers an irreplaceable waterfront setting with built-in demographics and virtually no direct waterfront competition. For owner-users, it provides functional space today while preserving substantial future redevelopment optionality. Perhaps most importantly, supply remains extremely limited. Commercial waterfront properties with direct river frontage, flexible zoning, and proximity to commuter rail are nearly impossible to replicate. With Tarrytown Metro-North Station only an eight-minute walk away and immediate access to Route 9, I-87, and the broader New York metropolitan region, the property combines destination appeal with practical accessibility. As Edge-on-Hudson continues to mature, the surrounding district is expected to transition from a redevelopment story into an established waterfront downtown environment. Buyers who recognize this trajectory today have the opportunity to secure a unique position before the area's next phase of appreciation is fully reflected in pricing. 42 River Street is more than a building. It is a strategic waterfront asset positioned at the intersection of location, scarcity, flexibility, and growth—qualities that increasingly define the most successful real estate investments throughout the New York region. In a market where comparable waterfront opportunities are virtually nonexistent, ownership of 42 River Street offers both immediate utility and long-term upside that few assets can match. The zoning allows for an array of uses including industrial and mixed use with retail and residential. This property is in the Riverfront Development District.
