Primary HB 4021
Introduced · Arizona House · Lead sponsor
appropriation; medical marijuana; veterans; fees

Maddy summaryHB 4021 allocates $10 million from Arizona's state general fund for fiscal year 2026-2027 to the Department of Health Services. This funding specifically covers the issuance and renewal of medical marijuana registry identification cards for veterans of the U.S. armed forces. The bill directly affects eligible Arizona veterans who use medical marijuana and are registered under Arizona law. The appropriation is exempt from standard budget lapse rules, ensuring the funds remain available for this purpose. This is a funding measure, not a policy change to medical marijuana or veteran benefits.

nuclear power plant; employees; requirements

Maddy summaryHB 2937 requires nuclear power plant contractors and subcontractors in Arizona to use a skilled workforce, mandating that skilled journeymen (experienced workers who completed approved training programs) make up 30% of the workforce by 2027, 45% by 2028, and 60% by 2029. It also requires contractors to pay skilled journeymen at least the prevailing wage for their occupation, which must meet or exceed the minimum wage. The Arizona Industrial Commission will create rules to verify worker qualifications and handle workplace violations. This bill directly affects contractors performing maintenance, repair, or installation work at licensed nuclear power plants in Arizona.

rural groundwater management areas; establishment.

Maddy summarySB 1742 establishes "rural groundwater management areas" in Arizona, requiring new subdivisions in these areas to prove adequate water supply before approval. It directly affects developers and local governments building housing in rural regions relying on groundwater, mandating either a water adequacy report from the state director or a written commitment from a designated water provider. Key provisions include strict conditions for exemptions (like water transported by vehicle/train) and require counties to report approvals to state agencies. The bill does not change existing water rights but adds a layer of review for new developments outside designated groundwater management zones.

municipal tax increment financing

Maddy summaryHB 4007 allows Arizona municipalities to create designated "municipal improvement areas" (up to 30 years) where they redirect tax revenue growth from increased property values to fund public infrastructure projects like roads, sewers, parks, and transit. It requires areas to meet specific criteria (e.g., blighted, needing redevelopment, or suitable for housing) and mandates approval from county, school, and community college districts. The bill specifies that captured tax increments - defined as the difference between current and original property tax values - must finance approved projects outlined in a development plan, including feasibility studies and revenue sources. This directly affects cities/towns seeking to finance public improvements through local tax growth, while prohibiting areas where residential taxes exceed state limits without state fund reimbursement.

Primary HB 2987
Introduced · Arizona House · Lead sponsor
income tax credit; historic preservation

Maddy summaryHB 2987 creates a new state income tax credit for owners rehabilitating certified historic structures in Arizona. It establishes a $30 million annual tax credit limit (increasing to $60 million after 2035) for projects meeting federal rehabilitation standards, requiring a cost-benefit analysis proving positive economic impact. The state historic preservation officer certifies projects based on a point system evaluating job growth, economic impact, and community support, with 60% of funds reserved for projects in cities/towns under 150,000 residents. Property owners must grant a restrictive covenant to preserve the structure for 24 months after certification, and larger projects require certified public accountant verification.

Primary HB 2988
Introduced · Arizona House · Lead sponsor
municipal tax increment financing; infrastructure

Maddy summaryHB 2988 allows Arizona cities to designate specific "Municipal Improvement Areas" within their boundaries to fund public infrastructure projects using redirected property tax increases. It authorizes municipalities to capture tax revenue growth (above the original assessed value) within these designated areas for projects like transit systems, water/sanitation infrastructure, streets, and public recreation facilities. The bill requires cities to adopt development and financial plans demonstrating community need, secure county/school district approvals, and limit area size based on city population. Projects must be completed within 30 years, and cities must reimburse the state if tax increases exceed constitutional limits for school funding in residential areas.

energy costs; large data centers

Maddy summaryHB 2949 requires large data centers (defined as facilities with at least 100 megawatts of peak demand) to directly pay for all energy costs related to their operations, including fuel, generation, and transmission. This applies to both public power entities (like municipal utilities) and public service corporations (like investor-owned utilities). The bill prohibits these data centers from passing these costs onto other utility customers, ensuring ratepayers aren’t burdened by the facilities’ energy expenses. The law aims to address cost allocation for high-energy data infrastructure without altering broader utility rate structures.

coverage; family and medical leave

Maddy summaryHB 2945 establishes Arizona's first state-administered family and medical leave insurance program, effective January 1, 2029. It provides wage replacement benefits for eligible workers needing time off for reasons including childbirth/adoption, caring for a family member with a serious health condition, pregnancy recovery, military family needs, or safe leave due to domestic violence, sexual violence, abuse, or stalking. The program guarantees up to 26 weeks of benefits for pregnancy or inpatient health conditions and up to 24 weeks for other qualifying reasons, with employers required to provide at least 12 weeks of leave. Benefit payments must begin within two weeks of a claim and continue every two weeks, applying to both employees and self-employed individuals who meet the defined eligibility criteria.

public policy; wage contracts; repeal.

Maddy summaryHB 2936 repeals Arizona's requirement that construction projects subject to environmental review must include labor agreements (like neutrality agreements) as a condition for approval. This directly affects construction companies and developers seeking environmental permits for facilities like power plants or transmission lines. The bill removes a provision that previously forced applicants to negotiate or comply with certain labor agreements before receiving approval. It does not change environmental review standards or requirements for pollution control. The repeal simplifies the approval process for construction projects by eliminating this labor-related condition.

perimenopause; menopause; task force

Maddy summaryHB 2929 establishes a 16-member task force focused on perimenopause and menopause care in Arizona. The task force includes health professionals, hospital representatives, educators, and community health stakeholders appointed by state officials. Its key duties are to identify ways to improve treatment and education for women experiencing these conditions, review health care curricula, and recommend changes to health care providers and institutions. The task force must submit findings to state leaders by December 2027 and 2028, and the bill expires on June 30, 2029. This is a procedural bill creating a study group, not a direct policy change affecting specific laws or funding.
