Background of Arizona's Homebuilding Permits Dispute
In 2023, the Arizona Department of Water Resources (DWR) implemented a policy rejecting new homebuilding permits in areas lacking a 100-year assured groundwater supply. This move aimed to safeguard water security for new housing developments, but drew legal challenges over the state's process in changing development rules.
Court Ruling Overturns Water Policy
Maricopa County Superior Court Judge Scott Blaney ruled earlier in 2026 that DWR had acted illegally by not following required legal procedures in altering homebuilding policy. Specifically, Judge Blaney determined the department failed to use the proper public process and legal procedures for rule making before imposing the new restrictions on granting homebuilding permits based on basin-wide groundwater supply concerns.
Request for a Stay Denied During Appeal
After the ruling, DWR—represented by attorney Bo Dul—appealed Judge Blaney’s decision and asked for a stay to keep the overturned policy in effect while the appeal is considered. Dul argued that allowing immediate resumption of home construction in affected areas could cause “irreparable damage” by undermining protections under the Groundwater Management Act. She maintained that more accurate modeling and updated data had showed groundwater was overallocated in some basins, necessitating stricter review measures for new developments.
However, Judge Blaney declined to grant a stay. He stated in his new order that DWR must continue using the 2023 rules for homebuilding permit decisions, and that the agency’s concerns about negative impacts were not supported by evidence. The judge emphasized that his decision simply restores the previous rules for determining where homes may be built, without prohibiting DWR from considering new water data within existing legal procedures.
Implications for Developers and Housing Development
This ruling carries immediate effects for developers planning new housing projects on the edges of the Phoenix metropolitan area and potentially other parts of the state. The court reaffirmed that any significant policy change regarding homebuilding permits and groundwater supply must be made through formal rule making, with required public hearings and opportunities for feedback—not through unilateral agency decisions.
The Homebuilders Association of Central Arizona, which filed the lawsuit leading to Judge Blaney’s original decision, had argued that DWR overstepped its authority by unilaterally changing policy. Their attorney, Sean Hood, held that while the department can consider new hydrological data, it cannot alter development rules or restrict home construction without following established legal processes. Hood disputed any agency suggestion that the ruling would force permits for sites lacking sufficient groundwater, stating that only the previously valid rules can be applied until new ones are lawfully adopted.
Looking Ahead: Broader Policy and Legal Ramifications
Judge Blaney’s refusal to stay his ruling during the appeals process sends a clear message that state agencies must adhere to established legal procedures when revising development and water use policies. The decision also serves as a reminder of the legal complexities that can arise between state regulatory bodies, developers, and environmental considerations surrounding groundwater supply and housing growth in Arizona.
The case continues as the state’s appeal is reviewed, keeping the spotlight on how Arizona manages water resources and future housing development. Any lasting change in policy will hinge on either new rule making by DWR or higher court decisions affirming or overturning the current ruling on policy procedures.
