ZIP Code 11786

Households in the 11786 ZIP code, centered on Stony Brook, bring in a median of $163,466 a year, with per-capita income at $59,971. That earning power sits alongside a median home value of $604,700, and the county's 1.73% effective property tax rate means owning at that level carries a substantial annual bill. Sales tax of 8.75% adds to the cost of everyday purchases. Together these figures describe an area where incomes are high but so are housing costs and the taxes tied to them, so residents' spending power depends heavily on how much of their earnings goes toward property taxes and daily consumption.
