To ensure compliance with House Bill 37, which designates execution by firing squad as the primary method of execution in Idaho as of July 1, 2026, the Idaho Department of Correction is set to begin phase two of the retrofit of the execution unit in F-Block at the Idaho Maximum Security Institution to implement this method.

The current estimated time frame to complete this retrofit is approximately 6 to 9 months. Following completion of the remodel, the execution team will need time to conduct training to be ready to carry out an execution by firing squad beginning July 2026. The Department is confident it will meet the required timelines and will do so on budget.

As of May 23, 2025, F-Block will be taken completely offline due to construction. As a result, all executions and execution-related procedures will be unavailable, including execution by lethal injection.
