Arizona school districts keep building despite falling enrollment and mounting debt

Scottsdale Unified School District in Arizona continues to approve large construction bonds even as student enrollment has dropped sharply, leaving taxpayers to fund underused facilities.

Across the United States, K-12 construction and renovation spending reached a historic $89.2 billion in the 2025-26 fiscal year, even as total enrollment fell by roughly 2 million since 2019. In Arizona, Scottsdale Unified School District exemplifies this trend: a 2012 audit showed the district was using only about 66 percent of its building capacity, yet voters approved a $229 million bond in 2016 that funded, among other projects, a $20,419,424 rebuild of Pima Elementary.

The new school was designed for 700 pupils but enrolled just 452 before reconstruction, later dropping to 296 in 2025-26, prompting a closure announcement for 2026 while debt service will continue until 2036. Despite enrollment falling to 19,472 in 2025-26—about half of its 2012 capacity—the district is pursuing an additional $375 million bond. Statewide, the Arizona School Facilities Board shows enough physical space for 1.3 million students, yet only 850,000 are enrolled, leading experts to call for minimum-capacity standards and broader co-location policies to let charter, magnet, private and micro-schools share vacant facilities.
