ZIP Code 11746

Households in the Stony Brook area's 11746 ZIP code earn a median of $164,589, with per-capita income at $71,105 — figures that position most families comfortably above national norms. That earning power meets a steep housing market, where the median home value is $695,200. At the county's 1.73% effective property tax rate, owners of such a home would owe roughly $12,000 annually, a substantial recurring cost. Sales tax in the area totals 8.75%, adding to everyday expenses. Together these figures show a high-income, high-cost corner of Long Island where salaries stretch further than the price tags might imply, though property taxes claim a meaningful share.
