Since the transfer of ownership from the U.S. Government, Sebastian Municipal Airport has undergone numerous facility changes and improvements.

The noted championship Sebastian Municipal Golf Course was built in 1981 on a 155-acre plot of land occupying a large portion of the airport property and local area flight training greatly increased operations at the airport in the mid- to late 1980s.

The addition of a number of commercial and private general aviation hangars and related aprons were developed along the west quadrant of the field.
