BOZEMAN, Mont. — June 25, 2026 — BlueLine Development and its partners officially broke ground on Rocky Mountain Flats, a landmark $109 million affordable housing development that will bring 296 affordable homes to Bozeman and is the largest tax credit bond-financed housing development ever undertaken in Montana. As Montana’s largest tax credit bond-financed housing development and one of the state’s largest affordable housing investments, Rocky Mountain Flats marks a major milestone in addressing Montana’s growing housing shortage while substantially expanding the supply of income-restricted housing in the Bozeman region.
Rocky Mountain Flats will offer a mix of one-, two-, three-, and four-bedroom apartment homes designed to serve working families, individuals, and households increasingly priced out of one of Montana’s fastest-growing housing markets. Serving households earning between 30% and 70% of Area Median Income (AMI), the development will provide high-quality, affordable housing options for residents at a variety of income levels. Upon completion, the community will help expand long-term affordable housing opportunities for nearly 300 households in the Gallatin Valley.
The project is being developed by BlueLine Development, a Missoula-based affordable housing developer, with Human Resource Development Council of Bozeman serving as the nonprofit general partner. Financing for Rocky Mountain Flats was made possible through a partnership among Enterprise Community Partners, JPMorgan Chase, the Montana Board of Housing, Impact Development Fund, and the Montana Department of Commerce.
“Bringing Rocky Mountain Flats to life required an exceptional collaboration among nonprofit, private-sector, and public financing partners. Together, those organizations assembled the resources necessary to create affordable homes in a market where housing affordability continues to be one of the community’s most pressing challenges,” said Maddy Mason, Development Director at BlueLine Development. “We’re grateful for the partnership and shared commitment that made this historic project possible.”
“Rocky Mountain Flats reflects our community’s commitment to accessible, high-quality housing,” said Lila Fleishman, Community Development Director for HRDC. “By offering 34 deeply affordable one-, two-, three-, and four-bedroom homes for households earning 30 to 40 percent of Area Median Income, we are ensuring families of all sizes have a stable place to call home. We are grateful to BlueLine Development and all our partners for bringing this vision to life and look forward to welcoming our new neighbors.”
“We’re proud to support Rocky Mountain Flats, bringing nearly 300 new affordable homes to Bozeman and marking a historic milestone for affordable housing in Montana,” said Isaac Silver, Executive Director, J.P. Morgan Community Development Banking. “At J.P. Morgan, our affordable housing investment work is rooted in the idea that strong communities create opportunity. Rocky Mountain Flats is a testament to what’s possible when we work with experienced developers like BlueLine Development to address critical housing needs and strengthen the fabric of the Bozeman community for years to come.”
For many future residents, Rocky Mountain Flats will provide access to stable housing near employment, schools, healthcare, and other essential services, helping families establish long-term roots in the Bozeman community.
