About Nassau County, NY
Nassau County sits immediately east of Queens on Long Island and is home to approximately 1.4 million residents, with its county seat in Mineola. The county is organized into three towns, Hempstead, North Hempstead, and Oyster Bay, two cities, Glen Cove and Long Beach, and dozens of incorporated villages, each with its own local government and, in most cases, its own building department.
Nassau holds a singular place in American history as the birthplace of the modern suburb. Levittown, begun in 1947, became the model for postwar suburban development nationwide, and the housing built during that boom still defines much of the county: capes, ranches, colonials, and split-levels on quarter-acre lots. The county is known for its highly rated school districts, its shoreline destinations including Jones Beach State Park, and consistently ranks among the highest median household income counties in New York State. Homeownership is the norm, and homes are commonly held for decades.
