North Haven sits across the bridge from Sag Harbor Village and functions, in practice, as the village's private estate extension. It is entirely residential. No commercial properties, no through traffic, and a deeply private character defined by large wooded lots and waterfront access to Sag Harbor Bay, Shelter Island Sound, and Northwest Harbor. Properties here range widely, from $3 million for a well-finished home on a two-acre parcel to $50 million for a trophy waterfront estate. For buyers who want serious privacy within minutes of the village.
