Why Great Falls
Great Falls is Montana's third-largest city, sitting on the Missouri River along the Rocky Mountain Front where the plains meet the mountains. It is anchored by Malmstrom Air Force Base and has a stable, working-class economy with some of the most affordable housing in Montana — median home prices in the low-$300,000s. The climate is colder and drier than western Montana, with long winters and short, warm summers. Tiny home buyers are drawn to Great Falls for land affordability, proximity to the Rocky Mountain Front and Glacier National Park, and a city commission that has been publicly receptive to tiny-house villages as part of its workforce-housing response.
Zoning & Placement
Great Falls, the seat of Cascade County on the Missouri River, applies all statewide Montana housing rules. Appendix Q of the IRC (adopted statewide December 7, 2019) makes foundation tiny homes of 400 sq ft or less legal under the state building code. HB 246 (2023) defines tiny dwelling units of 350–750 sq ft and authorizes cities to create dedicated zoning districts for them. SB 528 (effective January 1, 2024) requires Great Falls to allow at least one ADU by right on any single-family lot, and SB 532 (2025) removed size caps and added a mandatory 15-day expedited permit review for parcels already served by public water and sewer. SB 252 (2025) requires equal zoning treatment of manufactured and factory-built homes. The Great Falls City Commission has discussed tiny-house villages as a workforce-housing and homeless-services strategy. THOWs are registered as travel trailers with the Montana MVD and restricted to licensed RV parks for long-term residency. Verify current requirements with your local planning department before purchasing land or beginning construction.

What to verify locally
- • Confirm whether your tiny home will be treated as an ADU, a site-built dwelling, or a recreational vehicle.
- • Ask about utility hookup requirements, especially sewer, electrical service, and emergency-access setbacks.
- • Check whether long-term occupancy is allowed on the lot type you are considering.
- • Verify minimum square footage requirements for your zone classification.
ADU & Backyard Tiny Homes
ADUs are allowed by right on any single-family residential lot under state law SB 528 and SB 532. No owner-occupancy requirement. State size caps were removed in 2025; local standards on setbacks, height, and parking still apply. Parcels on public water/sewer are entitled to a 15-day expedited permit review. Build cost for a 600–800 sq ft detached ADU in the Great Falls market typically runs $140,000–$220,000, below Bozeman and Missoula pricing.
Where to Park
Communities, RV parks, and parking options in and near Great Falls.
Great Falls does not permit full-time THOW residency on standard residential lots. THOWs must be placed in licensed RV parks or campgrounds for permanent occupancy. Several long-term RV parks operate in the Great Falls area with monthly rates generally in the $400–$700 range — among the more affordable markets in Montana. On unincorporated Cascade County land, THOW placement is more permissive, though counties may still require setback and utility compliance.
