Primary SB 1117

barbering and cosmetology fund; enforcement

Maddy summarySB 1117 amends Arizona's barbering and cosmetology licensing law to clarify how enforcement costs are handled. It requires that fees assessed against licensees for violations (including investigation and hearing costs) be deposited into a dedicated "barbering and cosmetology fund" established under Section 32-505. These funds may be used by the regulatory board without annual legislative approval for enforcement activities like investigations, training, and administrative hearings. The bill directly affects barbering and cosmetology licensees and the state board overseeing their licensing. The legislature intends this funding to be ongoing, referencing prior appropriations.

unbuilt certificates; assured water supply

Maddy summarySB 1521 allows developers and landowners to transfer or sell unused water rights certificates (tied to undeveloped land) to other parcels within the same water basin, with specific conditions. It requires that the new parcel uses the water for the same purpose, meets construction deadlines (5 years outside master planned communities, 10 years inside), and notifies state officials. Municipal water providers can transfer these certificates freely within their service area, regardless of the original water source. This law directly affects developers purchasing or selling water rights for future construction projects in Arizona's designated water management areas.

subsequent AMAs; groundwater portability

Maddy summarySB 1518 allows farm owners with existing irrigation water rights (established before current regulations) to sell, lease, or transfer the unused water rights associated with portions of their land they choose not to irrigate. It enables these owners to retain or convey the unused water volume for use anywhere within the designated "subsequent active management area" for irrigation purposes. The bill requires owners to notify the state director using specific forms detailing the land not irrigated, the water volume, and the type of transfer (sale, lease, etc.). This bill was passed by the Arizona legislature in May 2025 but was vetoed by the governor on May 12, 2025, so it did not become law.

groundwater model; receipt; written findings

Maddy summarySB 1116 requires Arizona's groundwater department director to notify submitters within five days of receiving an alternative groundwater model and provide a detailed written response within 60 days. The response must specify whether the department accepts or rejects each finding in the model, along with the rationale for any rejections. This bill directly affects developers, environmental groups, or others submitting alternative groundwater models for review. The bill passed the legislature but was vetoed by the governor on May 12, 2025, so it did not become law.

Primary SB 1319
Signed into law · Arizona Senate · Lead sponsor
election officer certification training; yearly

Maddy summarySB 1319 requires Arizona county election officers to hold a valid certification from the Secretary of State before specific deadlines (January 1 before general elections in odd years, or June 1 in even years), with certifications expiring December 31 after each general election. It mandates the Secretary of State to provide annual training programs covering election procedures, law, and administration, and to submit an annual training plan to state legislators. The bill establishes an election training fund to reimburse cities and towns for training their election staff, which they can use instead of the state program. It exempts elected officials, precinct board members, and certain clerical personnel from these certification requirements. This policy directly affects county-level election staff responsible for managing voting processes.

gender transition procedures; provider liability

Maddy summarySB 1586 creates strict liability for healthcare providers who perform gender transition procedures on minors in Arizona. It requires providers to cover all costs of subsequent detransition procedures (reversing gender transition care) for 25 years after treatment begins, and allows minors to sue for medical expenses, damages, and attorney fees up to age 26. The bill prohibits providers from using contracts to waive this liability, stating such waivers violate public policy. The legislation was passed by the Arizona legislature in May 2025 but was vetoed by the governor on May 12, 2025, preventing it from becoming law.

Primary SB 1448
Passed · Arizona Senate · Lead sponsor
appropriation; on-farm irrigation efficiency fund

Maddy summarySB 1448 appropriates $10 million from Arizona's state general fund for fiscal year 2025-2026 to the existing on-farm irrigation efficiency fund established in 2022. This funding directly supports Arizona farmers and agricultural operations seeking to upgrade irrigation systems for improved water efficiency. The bill provides dedicated financial resources for projects that reduce water usage on farms, using the previously created fund structure. The appropriation is exempt from standard budget lapse rules, ensuring the funds remain available for the intended purpose.

minerals; metals; supporting domestic supply

Maddy summaryHCR 2044 is a non-binding resolution passed by Arizona's legislature affirming the state's mineral resources (including copper, uranium, and others) as critical to national security, economic growth, and the transition to green energy. It calls on federal and state governments to streamline mining permitting, support domestic production, and reduce reliance on foreign mineral imports. The resolution does not create new laws but formally expresses legislative support for policies fostering Arizona's mining industry and a domestic supply chain for critical minerals. It directly addresses government agencies and policymakers, not specific businesses or residents.

health profession regulatory boards; membership

Maddy summarySB 1235 amends Arizona statutes governing membership on three health regulatory boards (podiatry, chiropractic, and dental). It standardizes requirements including mandatory fingerprint-based criminal background checks for all members, specifies composition rules (e.g., requiring some members to be retired practitioners or laypersons), and sets term lengths and vacancy procedures. The bill directly affects the boards themselves by defining who can serve and how appointments are handled, with no changes to patient care standards or licensing requirements. Key mechanisms include requiring criminal checks via state/federal databases, limiting consecutive terms, and clarifying how vacancies are filled. The bill focuses solely on procedural governance of these boards, not on healthcare policy or patient outcomes.

epinephrine delivery systems

Maddy summaryThis bill allows trained school staff to administer epinephrine auto-injectors to students or adults showing signs of a severe allergic reaction during school hours or school events. Schools must stock at least two juvenile and two adult doses of epinephrine auto-injectors, obtain medical standing orders from qualified providers, and establish clear emergency protocols. It provides legal immunity for school personnel acting in good faith under these provisions, except in cases of gross negligence. The law applies to all Arizona public and charter schools.
