Idaho new construction report — Q1 2026

The bottom line

What this means for trade operators

If you're an LBM operator, roofing contractor, HVAC company, plumber, concrete crew, or any trade serving Idaho's new single-family construction market, this quarter's data points to a few practical actions:

• If you're not actively quoting the top 6 builders listed above, that's the call list for this week.
• If your service area covers any of the top-mover counties, you have leverage right now — builders there are scaling and looking for capacity.
• If you're considering expansion into Idaho, the Idaho dashboard has all counties scored against the trade you select. Drive-time analysis from your existing yard tells you which counties are reachable today.

This report is automatically refreshed every quarter from Census Bureau Building Permits Survey data plus county public records. The methodology is documented in our Census BPS data explainer.
