Arizona’s long-reliable engine of growth — new home construction — is showing signs of strain. A new report from the Arizona Legislature shows single-family building permits fell 12% between August 2024 and August 2025, marking a significant slowdown in a state where housing development has traditionally fueled economic expansion.
The decline is beginning to pressure policymakers, who are grappling with budget impacts, supply shortages and a continued affordability crisis.
Financing pressures stall new projects
Connor Devereux, market analytics director for CoStar Group/Homes.com, said builders are being squeezed by the same forces driving up costs nationwide. Higher interest rates have made borrowing more expensive, limiting builders’ ability to finance projects at a viable profit margin.
He noted that sluggish home sales in the Valley — especially among owners who would normally trade up to larger homes — reflect broader hesitation tied to economic uncertainty. Devereux expects activity to improve once interest rates ease.
Water constraints complicate development
Arizona’s housing slowdown is also tied to water policy. In 2023, Gov. Katie Hobbs directed the Department of Water Resources to stop issuing 100-year assured water certificates for certain high-growth areas on the outer edges of metro Phoenix, including Buckeye and Queen Creek. The move effectively paused new subdivision approvals.
Although Hobbs recently lifted that restriction, the effects are still rippling through the development pipeline. One project moving forward is Teravalis in Buckeye, which sold its first home and could ultimately bring as many as 100,000 residential units to the West Valley.
Economy shifts, but builders remain cautious
While Arizona’s economy has diversified beyond its traditional dependence on population growth — bolstered by major investments such as the Taiwan Semiconductor Manufacturing Co. plant in north Phoenix — analysts say builders will not ramp up construction until they are confident homes can be sold at prices buyers can afford.
For now, Devereux said, the math isn’t working in many parts of the market: if builders can’t construct homes profitably at entry-level price points, they pull back.
As Arizona continues to face affordability challenges and tight housing supply, the drop in building permits signals a complicated year ahead for both policymakers and the construction industry.
