Property Overview & History A century ago, this resilient waterfront structure served the bustling ferry trade between Greenwich, Connecticut and Bayville NY through the Long Island Sound. Following World War II, this historic commercial property was meticulously transformed into a premier two-family residence. Today, it stands as a modernized seaside retreat, offering a versatile floor plan surrounded by sweeping water views. Whether utilized as a private family compound or a strategic investment, this property represents a rare blend of historical charm and modern luxury.
Interior Sophistication * Expansive Space: Over 3,500 square feet of airy interior living space within a 5,000-square-foot total structure.
The Private Shoreline Experience true exclusivity with approximately 80 feet of private beach frontage and over 11,000 square feet of deeded land extending to the "mid-high tide line."
Owner/Broker Assurance To ensure a seamless transition, the property includes:
HOA – No Dues The Greenwich Avenue Home Owners Association is comprised of myself and the other few property owners on Greenwich Avenue. There are no mandatory Association Dues because street management is on a volunteer basis. I serve as president of the Association. Upon a sale, I can recommend the new owner as president to interact with the Village; or the several other owners can make the selection. A copy of the Greenwich Avenue Property Owners Association designation is available on request.

What are the taxes and major operating costs? Approximate Annual Expenses:
How will the Flood Insurance be "Pre paid" by seller at closing? To simplify the closing process, the seller will prepay the first year of this insurance premium in full in the form of a "credit" of $3,973 to be applied to the purchase price.
Is the flood insurance transferable? Yes. The current FEMA-backed flood insurance is fully assignable to the new owner.
What are the boundaries of the private beach? Unlike many coastal properties where ownership ends at the bulkhead, this deeded property extends approximately 80 feet wide and runs north all the way to the "mid-high tide line." This ensures your quarter-acre of deeded land provides a level of shoreline privacy and space that is rare for the area.
How is parking managed on Greenwich Avenue? Greenwich Avenue is a private-feel corridor with permit-only street parking for residents who live on Greenwich Avenue, with summer weekend day parking prohibited on the property side of the street. All enforceable by the Village Constable and Nassau County under NY Public Parking Law 2015-7. Additionally, the property features a private front gate for secure on-site parking.
What are the other neighboring beaches? To the east is the Bayville Soundside Beach, a gated community park with a playground available only to Bayville residents with a village permit. To the west is the private beach controlled by the Sound Beach Avenue property owners. This creates a quiet, residential buffer around the property.

How flexible is the floorplan? The approximately 5,000 sq. ft. structure with 3,500 sq. ft. of living space has a flexible two-family floor plan with soundproofing between the units. It can be utilized as an owner's duplex with 3 bedrooms and 2.5 baths, plus a rental duplex with 2 bedrooms, private terrace, full bath, separate central AC,
How flexible is the floorplan? The approximately 5,000 sq. ft. structure with 3,500 sq. ft. of living space has a flexible two-family floor plan with soundproofing between the units. It can be utilized as an owner's duplex with 3 bedrooms and 2.5 baths, plus a rental duplex with 2 bedrooms, private terrace, full bath, separate central AC, and zoned heat with built-in washer/dryer; or a rental studio with separate kitchen, washer/dryer, and full (tub) bath.
\
What does the Premium Home Shield Warranty cover? The property will be delivered with a one-year Premium Home Shield Warranty paid for by the seller. This covers the repair or replacement of major home systems, including the dual central air units, plumbing, and electrical systems, providing the buyer with absolute peace of mind for the first year of ownership.
How is the climate and hot water managed for a two-family setup? The home is engineered for total independence and redundancy. It features two separate Central Air units (one for each apartment) and dual hot water heaters, ensuring that both living spaces have dedicated, high-capacity utilities without interference.
What kind of outdoor shade is available? The deck and outdoor living areas are equipped with large, remote-controlled rollup awnings. These have been recently fully rebuilt by the factory to "as-new" condition, providing instant shade and protection at the touch of a button.
Are the living spaces truly private and quiet? Yes. To ensure maximum privacy between the two-family living areas, the shared walls have been soundproofed on both sides, significantly reducing noise transfer and creating a peaceful environment for both occupants
What are the storage and natural light features? The home is bathed in natural light via multiple skylights. For storage, there is a clean, stand-up attic with ample space—a rare feature in waterfront homes that often lack storage depth.
How is the property secured? A comprehensive online security camera system is installed, allowing for remote monitoring of the property from anywhere in the world. This is in addition to the remote-controlled front gate

How is the property secured? A comprehensive online security camera system is installed, allowing for remote monitoring of the property from anywhere in the world. This is in addition to the remote-controlled front gate
Does the home have fireplaces? Yes. The wood-burning fireplace is in the entry room with expansive windows facing the beach (currently serving as a formal dining room). It features a fully serviced chimney, chimney cover, cap, and flashing. The ceiling joists around the fireplace were professionally replaced. There is also a lifetime warranty on the custom-made stainless steel chimney cover that applies to any owner of the property. Receipts and warranty information are provided on request.
There is also a removable ventless gas fireplace in the other beach-facing room with expansive views of Long Island Sound (currently serving as the living room). This gas fireplace looks like a "built-in," but it can be removed if a new buyer wishes to remove the wall between the two large beach-facing rooms to create a massive open room on the ground floor.
What is the relationship with the neighboring restaurant? Walls Wharf is a long-standing local landmark that has been family-owned for generations. We maintain a positive relationship with the owners; they utilize valet parking seasonally to ensure the 20 Greenwich Avenue driveway remains clear. Their proximity offers a unique "amenity" feel, allowing for easy waterfront take-out and dining just steps from your door.
Are there noise restrictions for the nearby Crescent Beach Club? Yes. The Crescent Beach Club is a premier wedding destination, but it operates under a Memorandum of Understanding (MOU) with the local community. This agreement includes strict limitations on music volume, end times, and dates. 20 Greenwich Avenue is specifically included in this MOU, and a copy of the agreement is available for review upon request.
