Arizona’s HB 2999, signed by Governor Hobbs on June 5, 2026 (Laws 2026, Chapter 123), creates a new State Affordability Infrastructure District framework for financing public infrastructure tied to development. Districts may be formed by petition to the Arizona Finance Authority until June 30, 2036. The core idea is straightforward: qualifying landowners can spread the cost of roads, water, wastewater, sewer, drainage, mobility, broadband, public safety, and public-realm infrastructure over time through district bonds, assessments, taxes, fees, and other district revenues, rather than absorbing costs up front.
For real estate and infrastructure practitioners, the bill is significant because it pairs a new financing tool with guardrails. District obligations belong to the district alone, not the State, the Arizona Finance Authority, nor any city, county, or other political subdivisions. The statute also preserves local zoning and land-use authority, and it leaves utility service territories and certificates of convenience and necessity untouched.
The practical implications extend beyond housing. Master-planned communities, mixed-use projects, and potentially energy-adjacent or industrial developments may gain a more flexible path to finance backbone infrastructure. In turn, municipalities and counties will need to account for district-provided infrastructure when setting development fees. For environmental and ESG-focused stakeholders, the covered categories make water, wastewater, stormwater, transportation, open space, digital infrastructure, and environmental remediation central diligence issues.
The law also builds in transparency through public websites, annual reports, property-tax line-item disclosure, recorded formation documents, and residential seller disclosure notices. In short, HB 2999 gives Arizona a new infrastructure-finance platform with real consequences for land acquisition, entitlement strategy, public finance, environmental diligence, and consumer disclosure.
