BlueLine Development Breaks Ground on $109 Million Rocky Mountain Flats, Montana's Largest Affordable Housing Bond Development

BOZEMAN, Mont. — June 25, 2026 — BlueLine and its partners officially broke ground on Rocky Mountain Flats, a $109 million affordable multifamily development in Bozeman that will deliver 296 income-restricted apartment homes and is described as Montana's largest tax credit bond-financed housing development. The financing partnership includes Enterprise Community Partners, JPMorgan Community Development Banking, the Montana Board of Housing, Impact Development Fund, and the Montana Department of Commerce.
BlueLine Development's leadership described the coalition of nonprofit, private-sector, and public financing partners as essential to executing a project of this scale in one of Montana's fastest-growing housing markets.
Project Overview: Scale, Unit Mix, and Affordability Bands
Rocky Mountain Flats will offer one-, two-, three-, and four-bedroom apartment homes targeting households earning between 30% and 70% of Area Median Income (AMI). Of the 296 total units, 34 are designated as deeply affordable, serving households at 30–40% AMI, according to statements from the Human Resource Development Council of Bozeman, which is serving as the nonprofit general partner on the development.
At a total development cost of $109 million across 296 units, the implied all-in cost is approximately $368,000 per unit.
