St. Luke’s Boise Development Plan

Building on Our Promise

St. Luke’s roots of caring for people in Idaho trace back to 1902. Over the past 120 years, we’ve grown into a national leader in quality — a top 15 health system in the U.S. for nine consecutive years — and the state’s only Idaho-based, not-for-profit health system. Each year, St. Luke’s clinics across the region see nearly 2 million patient visits. In the most recent fiscal year, more than 4,000 babies were delivered at our Boise Medical Center and more than 20,000 surgeries were performed — approximately 56 every day. As Idaho’s population continues to grow — Idaho was the second-fastest growing state in the nation in 2022, according to U.S. Census Bureau reports — we remain committed to meeting the health care needs of our communities.  

Throughout this multi-year project, we have collaborated with city and county officials, health care providers, patients, neighbors, donors, businesses, nonprofits and more. In 2015, the city of Boise approved St. Luke's master plan to update the Boise Medical Center. This led to the construction of the innovative and kid-friendly St. Luke’s/Idaho Elks Children’s Pavilion, connected to Idaho’s only children’s hospital via a skybridge, and the new, state-of-the-art auxiliary facilities, including a new shipping and receiving building, designed and programmed to support future additions to the medical center, including the new hospital tower and medical office plaza.  

New Phase: Hospital Tower and Medical Office Plaza

St. Luke’s will soon launch efforts to construct a new hospital tower and adjoining medical office plaza. These new buildings, all part of the city of Boise-approved master plan, will directly improve access to care for patients, while increasing St. Luke’s ability to care for the growing number of patients in our communities.

Bannock Street Corridor

After several years of planning and testing, Boise City Council approved the public access easement for Bannock Street corridor running through the St. Luke's Boise Medical Center campus. The collaborative efforts have transformed the one-block corridor into a dynamic shared space.

Master Plan Overview

The St. Luke's Boise development project will evolve over several years. This is not a “single project” proposal, but a multi-phase plan that will occur in stages over the years to come. At its core is our commitment to create an environment in which we can provide the best possible care for patients and families—an environment geared toward safety, healing, and comfort, following the most proven, effective, and efficient practices in healthcare facility design.
