- From 1990 to 2016, the number of single-family homes in Montana grew by 50 percent, from roughly 224,000 homes in 1990 to 337,000 in 2016.
- Nearly half of homes built from 1990 to 2016, were constructed on large lots with average lot sizes exceeding 10 acres.
- Since 1990, 1.3 million acres of undeveloped land have been converted to housing, equal to the total acreage in Montana managed by the National Park Service.
- Without careful planning for our future, conversion of undeveloped land to residential housing will be detrimental to Montana’s water quality, wildlife, and heritage of open space.

Montana rapidly losing space to home building
Loss of Open Space Impacts Montana’s Future, Quality of Life
Montana home construction starts declined during the Great Recession. Since then, the state has rebounded and continues to attract new residents. Home construction has picked up again–primarily in fast-growing cities, but much of it in more rural areas of Montana as well.
The tendency to build on large residential lots—with parcels of 10, 20, and even 40 acres in size—is quickly changing Montana’s culture, economy, and natural resources. Large lot development poses challenges for wildlife, water quality, and the state’s heritage of wide open lands.
Fortunately, vast areas of undeveloped land remain and Montanans can contain the negative impacts of growth through careful discussion, coordination, and planning.
