A one-room schoolhouse was built in 1830, which is the current site of the Uniondale Public Library. Hofstra University was established in the estate of William S. Hofstra (now Netherlands Hall) in 1935.
In the early 1970s, several Uniondale residents attempted to incorporate their hamlet as a village, citing dissatisfaction with the way their community was being represented on the board of the committee for redeveloping Mitchel Field, regarding matters like policies and the plans. Their incorporation plans were unsuccessful, and Uniondale remains an unincorporated hamlet governed by the Town of Hempstead.
Until 2015, the area of Uniondale north of the Hempstead Turnpike was a separate census-designated place called East Garden City.
