Sag Harbor prices by position more than by named street. The trophy market is the bay and harbor waterfront, the houses with a dock and a sunset over the water on the North Haven side and the village edges. The walk-to-village houses in the historic district, the captain's houses and their neighbours within a stroll of the wharf, the bookshop, and the restaurants, hold a different premium built on walkability rather than water frontage. The historic bay-beach communities of Azurest, Sag Harbor Hills, and Ninevah on the eastern shore, and the Redwood peninsula, fill out the middle of the market.
You pay most for a dock and a bay view, next for a short walk to Main Street, and least for an inland house a drive from both. North Haven, the wooded peninsula reached by a short causeway, holds the largest waterfront estates and the South Ferry crossing to Shelter Island.
The Suffolk County occupancy tax
Suffolk County charges a hotel and motel occupancy tax of 5.5 percent on short-term rentals, in effect since June 1 2023 and collected by the host from the renter. On a $70,000 August week that is $3,850. Unlike a hotel stay, a whole-house rental let as a residence is generally outside New York State sales tax, which applies to hotel-style occupancy, so the 5.5 percent county tax is usually the main tax line. Confirm how the operator shows it on the invoice.
The village permit and the two-town wrinkle
The Village of Sag Harbor requires a rental permit, in force since January 1 2024, and a house cannot be lawfully let without it. The wrinkle is that the village straddles the town line, with part in the Town of East Hampton and part in the Town of Southampton, so a house may also fall under a town rental rule depending on its exact location. The Town of Southampton requires its own rental permit with a 14-day minimum let. Ask which town your house sits in and confirm it carries the village permit and any town permit before you sign, because an unpermitted let is an enforcement risk that can disrupt a booking.
The chef, the clean, and the deposit
Most Sag Harbor houses let self-catered with a turnover clean of $800 to $2,500 depending on size. A private chef, the upgrade most summer renters want, runs $600 to $1,200 per day plus food and books up early for July and August. Expect a refundable security deposit of $7,500 to $35,000 by check or card hold on the larger houses, returned within two to four weeks of checkout, and a 50 percent deposit at booking on a peak-season week.
