In 2005, a group of Machiasport year-round and seasonal residents established the Committee to Save Liberty Hall. Following extensive discussion, the Committee engaged John Turk of ttl-Architects in Portland, a firm specializing in historic preservation, to conduct a full Building Conditions Assessment. The objective was to define the work required to save the building and to draw up a schedule of priorities necessary for its restoration.

In 2006, a multiphase plan for the restoration of Liberty Hall was launched. Phase One was successfully completed in 2007; Phase Two in 2009; and Phase Three is currently being completed (2021-22).

Preserving the building's historical integrity has been the highest priority. All restoration work has been carefully carried out in accordance with the Secretary of the Interior's Standards for the Treatment of Historic Properties.
