The old building on the corner of NY 300 and Gardnertown Road dates back to the early 20th century and was originally Gardnertown Elementary School. When the current school, now called Gardnertown Magnet School, was built in the mid-1950s, this building became Newburgh Town Hall. It remained so until 1973, when the current town hall was built right next door. At that point, the historic old building became police headquarters. When the current police headquarters was built in the late 1980s, adjacent but in the other direction, facing Gardnertown Road, this building became a secondary town hall, housing the code compliance, building, zoning, and planning board offices.
