Idaho recorded the fastest housing unit growth rate in the country in 2025, marking the second consecutive year the state has claimed that distinction, according to new data from the Idaho Department of Labor released Sunday.

The state’s housing stock expanded by 2.1% last year, adding more than 17,000 units. The growth rate was the highest of any state in the nation.

Five-Year Trend

Zooming out, Idaho’s housing inventory has climbed 12.3% since 2020, representing the construction of more than 93,000 units over that span. That five-year rate ranks second nationally, trailing only Utah at 12.9% and outpacing Texas at 10.4%. Idaho’s cumulative growth is more than double the national rate of 5.3% over the same period.

Since 2020, Idaho has ranked either first or second among all states in annual housing unit growth every year.

County-Level Leaders

Five counties — Teton, Canyon, Ada, Bonneville, and Kootenai — each grew their housing supply by more than 14% over the five-year period. In 2025 alone, Ada County added the most units in raw numbers at 5,026, while Clark County added just one unit at the low end.

The fastest growth rates last year belonged to Teton County at 5%, Bonneville County at 4.4%, and Canyon County at 3.7%. All three ranked in the top 30 nationally among counties with at least 5,000 housing units — a distinction those same counties also held in 2024.

Governor’s Response

Governor Brad Little credited permitting reform and workforce development for driving the numbers. “Idaho’s nation-leading housing unit growth is no accident,” Little said, pointing to the state’s LAUNCH career training initiative and efforts to reduce regulatory barriers in the construction sector.

Little also acknowledged that strong growth figures do not by themselves resolve the state’s affordability challenges. “Housing affordability and accessibility remain top concerns for Idaho families, and we have more work to do,” he said.

What’s Next

The data arrives as housing costs continue to be a central concern for policymakers and residents across the Treasure Valley and other fast-growing parts of the state. Idaho’s population growth has placed sustained pressure on housing supply in the Boise metro area and in communities like Rexburg and Coeur d’Alene, making construction output a closely watched indicator for state economic planners.

Whether the momentum in new construction translates into improved affordability for working families remains an open question heading into the second half of 2026. State officials have indicated housing policy will remain a priority in the executive branch, though the Idaho Legislature adjourned earlier this spring.
