Missoula Zoning & Land Use Guide
Key Zoning Facts
Missoula Zoning Overview
Missoula is Montana's second-largest city, nestled in a valley at the confluence of five mountain ranges in western Montana. Home to the University of Montana, the city has a distinctive character blending college-town culture with outdoor recreation and a growing technology sector. Missoula's zoning code is administered by Development Services and reflects the community's emphasis on walkability, infill development, and environmental stewardship.
The city adopted a major zoning update as part of its "Our Missoula" growth policy, which encourages higher-density housing near transit corridors, mixed-use development downtown, and preservation of open space and agricultural lands on the urban fringe. Missoula's geographic constraints -- surrounded by mountains and bordered by the Clark Fork and Bitterroot rivers -- make efficient land use particularly important.
Key Zoning Districts
Missoula's zoning code includes residential districts from R-21.6 (large-lot) to RM-1 (high-density multi-family), commercial districts from C-1 (Neighborhood Commercial) to C-3 (Central Business), and industrial zones. The city has also created special overlay districts for the university area, the riverfront corridor, and historic neighborhoods.
ADU Regulations
Missoula has been a leader among Montana cities in supporting accessory dwelling units. Under state law (SB 528 and HB 211), the city must allow ADUs and cannot impose owner-occupancy or additional parking requirements. Missoula has developed pre-approved ADU design plans to make the permitting process faster and more affordable for homeowners.
Development Process
The Missoula development process starts with a pre-application meeting with Development Services staff. Building permits require plan review and inspections. Larger projects may need subdivision review, conditional use permits, or planned unit development approval through the Planning Board and City Council.
