The Hay Gaol is in fair condition. The paintwork in the cell block is generally poor and the site has problems with rising damp and white ants. The eastern perimeter wall is considered to be in an unstable condition. At some early stage, part of the isolation block was demolished. After 1974 a large steel shed was added to the rear of the cell block and two large sheds built outside the eastern perimeter wall. These elements are intrusive rather than of heritage significance.
