Funding for the modernization and renovation of the Prince Jonah Kuhio Kalanianaole U.S. Courthouse and Federal Building is made available through the American Recovery and Reinvestment Act (ARRA) of 2009.

The modernization and renovation of the nine-story Federal Building and five-story U.S. Courthouse will include a comprehensive replacement of the core mechanical, electrical, life-safety, and plumbing infrastructure. Repairs and alterations will include replacement of most of the air cooling and circulation systems, major upgrades to the electrical power systems, and other life-safety capabilities; new ceilings and lighting; extensive renovation of the restrooms and associated plumbing; sealing and re-finishing of deteriorated areas; and reworking of the fire sprinkler systems.

Improvements will also include accessibility for disabled people to be more efficient and functional. Once complete, the Federal Building and U.S. Courthouse project will reduce energy consumption by 30 percent and will be registered with the LEED certification goal of Silver through United States Green Building Council (USGBC).
