It was not until the 1950s that the courthouse undertook major renovations. In 1955, the distillate stoves were replaced with butane heaters allowing the chimneys to be reduced to roof level while the roof was also replaced. In 1956, the roof would be replaced again for the fifth or sixth time since the building's completion in 1911. New flooring was installed in the courtroom and some offices, and the courtroom ceiling was lowered for acoustics and heating. In the courtroom, theater-style seating was installed while the upper gallery was removed. A new plywood bench for the judge and a jury box with matching railing were built. The stained glass window behind the judge's bench was boarded and plastered. Downstairs, exterior steel doors were installed, and a counter shelf was built for the office of the sheriff and tax-assessor collector along with five fire extinguishers provided for the premises. In 1957, two gas heaters with electric blowers were installed in the space formerly occupied by the courtroom's upper gallery to heat the courtroom. The building's roof would require replacement in 1974 and again 1975.
