Boise Centre Eyes Major Expansion After Greater Boise Auditorium District Acquires 4-Acre Site in Idaho’s Capital City
The Greater Boise Auditorium District has purchased a 4-acre lot in south downtown Boise, Idaho, setting the stage for a significant expansion of the Boise Centre — the state’s largest convention center. The acquisition, announced last week, positions the district to grow its capacity at a time when demand for the venue has reached record levels and dozens of events are being turned away each year due to limited availability.
Background: A Record-Breaking Venue Running Out of Room
The Boise Centre, operated by the Greater Boise Auditorium District using revenue from a 5% hotel tax, had a breakout year in 2025. The convention center recorded $51.2 million in revenue, hosted 278 events, and welcomed 170,000 guests — all new records for the facility. That success, however, has come with a growing problem: the venue simply cannot keep up with demand.
A 2025 study conducted by third-party firm Johnson Consulting found that the Boise Centre loses an average of 115 events annually due to a lack of availability. The consulting firm recommended the addition of a 100,000-square-foot exhibit hall to address the shortfall and make the venue more competitive on a regional and national scale.
The newly purchased land sits at the northeast corner of 11th and River streets, just north of Ann Morrison Park. The site currently contains a mix of office spaces and warehouses, which would likely be demolished as part of any development plan.
Key Details: What the Land Purchase Means for Boise
The 4-acre acquisition came after roughly a year of work by an exploratory committee evaluating options for expansion. District board chair Kristin Muchow described the move as a measured, strategic step forward.
“This is a deliberate, responsible first step,” Muchow said. “We’ve done the analysis, we’ve evaluated our options, and we’re moving toward securing land that gives us a real foundation to build from.”
While the Johnson Consulting report recommended a new exhibit hall, district officials have also explored the possibility of building a large multi-sport complex on the site. Mary-Michael Rodgers, Associate Director of Communications for the Boise Centre, noted that sports facilities can be less expensive to construct than traditional event venues, in part because they require less specialized technology infrastructure.
“These multi-sports complexes are incredibly successful because sports tourism is very much in demand,” Rodgers said. “There’s cities like Pocatello right now that have sports facilities, and they’ve been very successful.”
Rodgers added that Boise’s existing facilities fall short of what would be needed to host large-scale sporting events. “We have smaller sports facilities, for sure,” she said. “But not something that can do 15 basketball or volleyball courts under one roof.”
No final decision on the type of facility has been announced. District leaders say they will continue evaluating what development best serves the Boise community before committing to a specific project.
Impact on Ada County Residents and Taxpayers
The expansion of the Boise Centre carries real economic implications for Ada County and the broader Treasure Valley. Convention and event tourism generates spending at local hotels, restaurants, and businesses — tax revenue that supports city and county services without direct cost to residents. A larger, more competitive venue could capture a greater share of that economic activity, much of which is currently being lost to competing cities.
“A larger, more competitive Boise Centre would mean more events, more visitors and a measurably stronger economic return for the Boise community,” the district said in a statement.
District Executive Director Cody Lund emphasized that the existing convention center’s day-to-day operations will not be disrupted once a project is finalized and construction begins.
“Boise Centre is a community asset,” Lund said. “Protecting what we’ve built here is just as important as planning for what comes next.”
As Idaho’s population continues to grow and Boise cements its place as a destination city, the pressure on public event infrastructure is only expected to increase. The land purchase gives the district a concrete starting point for planning a facility that could serve Ada County for decades to come.
What Comes Next
The Greater Boise Auditorium District will now shift focus to determining the best use of the newly acquired parcel. That process will include community input and further analysis before any final project design is selected.
