Cost to Build a 2,000 sq ft Home in Montana (2026)
A 2,000 sq ft two-story home in Montana costs about $350,056 to build at mid-range quality — $175/sq ft, land excluded. The median new home in the West is 2,090 sq ft, so this build is right at the regional median.
Is 2,000 sq ft a normal size for Montana?
29% of new homes completed in the West fall in the 1,800–2,399 sq ft range that a 2,000 sq ft build sits in — the single most common size bracket in the region.
The Census Bureau measures every new single-family home completed in the country. In the West — the region Montana sits in — the median came in at 2,090 sq ft and the average at 2,336 sq ft. A 2,000 sq ft build is therefore right at the regional median.
