Residential Land for Sale in Sag Harbor, New York

Set on 1.92 acres in North Haven, this property offers two compelling paths: a comfortable, fully livable home as it stands today, or the chance to create a remarkable new Hamptons estate. In one of Sag Harbor's most sought-after waterfront communities, surrounded by $20M+ estates, the scale of the parcel supports a true compound with room for a substantial residence, accessory structure, pool, and tennis. A conceptual site plan illustrates a 7,118+- SF main house and 1,067+- SF accessory structure, demonstrating the full development potential. Beach access is just moments away, ideal for kayaking, paddleboarding, and enjoying the harbor. The neighborhood is beautifully maintained, quiet, and private - an elegant, established enclave with generous spacing between homes and mature natural landscape. The current residence is in excellent condition and can serve as your home base while you design, permit, and build, or it can be renovated to suit your style. Whether you choose to enjoy it immediately or shape an entirely new vision, the property offers rare flexibility and significant upside. Separated but only minutes from Sag Harbor Village, this location combines peace, prestige, and opportunity in equal measure.
