The alternative to building a new courthouse is based off of a 2009 study presented to the Johnson County Board of County Commissioners during a Committee of the Whole session on October 22, 2009. This study evaluated the viability of continued use of the existing courthouse. The least costly option in this 2009 study included a four-story addition on the south side of the courthouse and included renovation to the existing facility. This option indicated six stages of construction occurring over 13 years.

This alternative to a new courthouse did not fully address systemic inadequacies with the existing facility such as ADA, security, circulation separation, and the addition of waiting & meeting space. Should a new courthouse not be approved, County staff will need to revisit this alternative to update the scope of work, via a concept development study, and re-evaluate the total cost of this alternative. Costs for this approach are expected to exceed those estimated in 2009.
