A new administration building was constructed between 1931 and 1947 and was designated a Federal Heritage Building (FHBRO) in 2002.

In 1962, Rockwood Institution, a minimum-security facility, was established immediately adjacent to Stony Mountain Institution.

Stony Mountain is a clustered institution, with a residential-style minimum facility, consisting of small group accommodation houses; a dome-style medium facility with direct observation cell ranges, and the range-style maximum facility with direct observation cell ranges.
