Delivered backyard studio or garden office cost, including foundation, electrical hookup, permits and delivery in Montana (2026)

What drives the cost in Montana

Montana has no general sales tax, which lowers the price of a prefab unit, but long freight distances, sparse installer networks and heavy snow loads tend to push the delivered cost back toward the national typical range. Deep frost and cold winters make foundation depth, roof rating and a cold climate heating solution the main technical questions, and rural lots can involve long electrical runs. Permitting is minimal in many counties but stricter in cities such as Bozeman and Missoula, where growth has also raised labor rates.

Tips for Montana buyers

• Get a written freight and placement quote, since distance from the manufacturer may be the biggest regional surcharge you face.
• Ask for a roof snow load rating suitable for your elevation and a heating system rated for very cold ambient temperatures.
• Measure the electrical run from the house carefully, as long trenches on large rural lots can dominate the site work budget.

Ranges are hedged planning estimates derived from a national typical range and a local index, not quotes. Typical all-in delivered cost for a premium prefab backyard studio or garden office, combining a unit price of roughly 5,000 to 15,000 USD with foundation, electrical run, permits and delivery; it varies widely by size, finish level, site conditions and local labor, and custom builds or large units can cost more.
