What Are Montana Impact Fees?
Montana authorizes impact fees under Mont. Code Ann. §§ 7-6-1601 to 1604, requiring a documented service-area report and advisory committee review. Cities such as Bozeman, Missoula, Kalispell, and Belgrade charge fees across water, wastewater, streets, and fire.
The Gallatin Valley's boom has made Bozeman one of the mountain West's most fee-intensive small metros, while much of rural Montana charges only utility hookups. Montana figures on impactfees.org are model estimates scaled to community size; confirm adopted schedules with each city.
Montana figures are illustrative estimates from our statewide cost model — calibrated to local construction costs and community size — rather than verified fee schedules. Use them for early budgeting and site comparison, and see our methodology for how estimates are built.
