How does Idaho compare with the national average for a basement remodel?

Homeowners in Idaho typically recoup about 68% of the project's cost at resale, versus ~71% nationally. Idaho is part of the Mountain Census division, which has the 4th-lowest renovation resale returns of the 9 U.S. divisions.

What most affects the actual return in Idaho?

Recency and condition. In Roots' model, work under 2 years old counts fully toward resale value, then depreciates toward ~20% after 10 years. A home with a documented maintenance record also typically sells closer to asking. Market conditions in the Mountain division set the regional baseline.

Where do these numbers come from?

Roots calibrates the national baseline for a basement remodel against the 2025 Cost vs. Value Report (Zonda), then applies a Mountain-division adjustment derived from division-level averages in the 2024 Cost vs. Value Report, plus the model's own age and condition factors. Figures are modeled estimates, not appraisals.

Is a basement remodel worth it in Idaho?

Quick answer: Only partly, in dollar terms. In Idaho, a basement remodel typically returns about 68% of its cost at resale, below the ~71% national average. It adds real value, but treat it as an improvement you'll enjoy rather than an investment that pays for itself.

How Idaho compares

Idaho is part of the Mountain U.S. Census division, which has the 4th-lowest renovation resale returns of the 9 divisions in Roots' valuation model. In practice that means a basement remodel that returns ~71% of its cost nationally typically returns ~68% for a Idaho home.

The same regional adjustment applies across the division (Idaho plus AZ, CO, MT, NM, NV, UT, WY). Nationwide, the spread for this project runs from ~58% in the West North Central division to ~83% in the Pacific division. See the national breakdown for every region.

The Mountain market

The Mountain West has drawn steady in-migration for years, and its housing stock skews newer than the national average. The dry, high-sun climate is gentler on some parts of a home and harder on others: sun exposure ages roofs and finishes, while low humidity spares basements and framing.

With so much recent construction, interiors that match new-build standards hold their value best here.

Protect the value you add

Whatever the project returns on paper, condition decides what you actually get: in Roots' model the value of completed work fades as it ages, and a documented maintenance record helps a home sell closer to asking. If you're planning around resale value, start with upkeep. The free maintenance checklist generator builds a seasonal schedule for Idaho homes in about a minute.
