ADU Design in Montana: what governs your project
Montana's 2023 legislature passed HB 492, which requires municipalities to allow at least one accessory dwelling unit by right on any lot zoned for single-family residential use. The law bars cities from imposing owner-occupancy requirements, excessive minimum lot sizes, or design standards stricter than those for the primary home.
Energy code
Local jurisdictions set size caps and utility connection rules; state law limits the fees and review hurdles cities can impose. Expect straightforward administrative approval rather than conditional-use hearings in Montana's cities.
Permitting & plan check
Billings, Missoula, Bozeman, and other larger cities run their own building departments with published review processes. Many smaller jurisdictions rely on third-party reviewers or county-level review. Rapid growth in Bozeman and the Flathead has stretched review capacity in recent years.
