In 1988, the administration of Governor Robert D. Orr proposed that the Indiana General Assembly renovate the state house as part of "Hoosier Celebration '88", the year of the building's 100th anniversary.
The General Assembly approved, and the building had an extensive, $11 million renovation that continued until 1995.

During the renovation process, all of the state house's stonework, consisting of marble, granite, and limestone columns and blocks, was cleaned and polished.
All of the building's woodwork was repaired or replaced.
Broken glass in the central dome skylight was replaced.
 The building's lighting was updated with new chandeliers based on the original designs, and most interior walls were repainted.
The building was wired for a new data network to make the building ready for 21st-century technology.

In 1984, the Indiana State House was added to the National Register of Historic Places, and it remains a protected building.
The state house is open for public tours during the work week and with limited tours during weekend mornings.
