ZIP Code 11951

Stony Brook's 11951 ZIP code sits in solidly upper-middle-income territory, with a median household income of $110,862 and a per-capita figure of $36,849. Homes here carry a median value of $355,400, and the county-level property tax rate of 1.73% means owners pay a substantial share of that value each year in taxes. Add an 8.75% combined sales tax on purchases, and the overall cost of living reflects a community where earnings are strong but so are the taxes that come with owning property and spending locally.
