Columbia Falls Zoning & Land Use Guide
Key Zoning Facts
Columbia Falls Zoning Overview
Columbia Falls is a small city in the Flathead Valley of northwestern Montana, located at the west entrance to Glacier National Park. Once an aluminum smelting town, the community has transitioned toward tourism, recreation, and wood products as its economic base. Columbia Falls has grown alongside the broader Flathead Valley boom, though it remains more working-class in character than nearby Whitefish.
The city's zoning framework accommodates a mix of residential, commercial, and light industrial uses. Columbia Falls has worked to attract commercial development along its Highway 2 corridor while maintaining the livability of its residential neighborhoods. The proximity to Glacier National Park makes the community a natural base for visitors.
Key Zoning Districts
Columbia Falls uses R-1 through R-3 residential districts, B-1 and B-2 business districts, and industrial zones. The Highway 2 corridor is the primary commercial strip, and the city has provisions for planned developments.
ADU Regulations
Montana state law (SB 528 and HB 211) requires Columbia Falls to allow ADUs. No owner-occupancy or parking mandates can be imposed. ADUs help address the housing needs of workers in the tourism and recreation economy.
Development Process
Building permits are processed through the city's Building Department. The Planning Board and City Council handle zoning changes and major development proposals.
