Building an ADU in Montana means accounting for its distinct seasons. The long winters can impact project timelines, especially for foundation work and exterior framing. We plan for these conditions to keep your project moving forward. The type of existing home you have—whether it's a traditional single-family house or a cabin—will influence the ADU design and how it integrates with your current utilities. Understanding these factors helps determine the scope of work.
