ZIP Code 11755

ZIP code 11755, centered on Stony Brook, sits firmly in affluent territory. A median household income of $119,364 and per-capita income of $50,381 place it well above national norms, while a median home value of $601,600 reflects a high-cost housing market. That price level brings a county property tax rate of 1.73%, a substantial annual obligation on a home at that value. Add an 8.75% combined sales tax, and the overall cost of living here runs steep. Households here generally have the earnings to absorb these taxes, but the totals are far from trivial.
