rainwater harvesting; appropriation

Maddy summaryHB 2650 creates a state-funded rainwater harvesting grant program in Arizona to support water conservation. It allows eligible homeowners, non-profits, or organizations focused on water conservation to apply for two types of grants: Level 1 for simple passive systems (reimbursing up to $500 for materials/labor), and Level 2 for complex active systems (reimbursing up to $2,000 based on tank size). The program excludes costs like pumps, irrigation systems, unlicensed labor, and landscaping materials. Funding for the program is appropriated from the state general fund for fiscal year 2026-2027.

blue envelope program; autism spectrum

Maddy summaryHB 2651 establishes a voluntary "Blue Envelope Program" for drivers diagnosed with autism spectrum disorder in Arizona. Participants receive a standardized blue envelope (available in English and Spanish) containing their vehicle registration, insurance details, and communication tips for law enforcement during traffic stops. The program ensures confidentiality by prohibiting disclosure of participants' identities and requires collaboration between the state, University of Arizona, and community stakeholders to design the envelope's contents based on expert guidance. This directly affects individuals with autism spectrum disorder who drive, aiming to improve communication during police interactions.

terminally ill individuals; end-of-life decisions

Maddy summaryHB 2243 creates Arizona's "Medical Aid in Dying" program, allowing terminally ill adults to obtain a prescription for self-administered medication to end their life. It directly affects Arizona residents with a terminal illness (expected to die within six months) who have full decision-making capacity and meet strict safeguards. Key provisions require two non-family witnesses to sign a written request, mandatory counseling to rule out depression, physician evaluations confirming the terminal diagnosis, and detailed discussions about all treatment alternatives - including hospice and palliative care - before a prescription is issued. The law prohibits physicians from administering medication and requires patients to self-ingest the medication, with all steps documented for the Department of Health Services.

advertising; produce abortion; conception; repeal

Maddy summaryHB 2465 is a procedural bill that repeals Section 13-3605 of Arizona’s Revised Statutes. It does not create new policies or affect specific groups, as it solely removes an existing legal provision. The bill is currently in its early legislative stage, having received its first House reading on June 27, 2025. The summary cannot describe the repealed law’s content, as the bill text does not specify what Section 13-3605 previously regulated.

TPT; online lodging marketplace; reporting

Maddy summaryThis bill (HB 2354) amends Arizona's tax confidentiality rules (ARS § 42-2003) to clarify when the state tax department may disclose taxpayer information. It primarily affects businesses and individuals who interact with Arizona's tax system by expanding permitted disclosures to specific entities, such as the Arizona Commerce Authority, for administering tax credit programs (e.g., renewable energy incentives and film production credits). Key provisions allow the Commerce Authority to access taxpayer data to verify eligibility for tax credits under sections 42-12006, 43-1083.03, 43-1164.04, and related programs. The bill does not address online lodging marketplaces or reporting requirements as its title suggests; the title appears mislabeled based on the actual tax disclosure provisions.

telemedicine; abortion prohibition; repeal

Maddy summaryHB 2463 repeals Section 36-3604 of the Arizona Revised Statutes, which prohibited abortion services provided through telemedicine. This repeal removes a specific legal restriction that previously blocked telehealth providers from offering abortion care in Arizona. The bill does not create new abortion policies but eliminates an existing prohibition on telemedicine for abortion services. As a result, abortion providers could potentially offer telemedicine-based abortion care without violating this statute if the bill becomes law.

immigration; government agencies; prohibited acts.

Maddy summaryArizona's HB 2807 restricts how local government agencies interact with federal immigration authorities. It prohibits municipal law enforcement from stopping, questioning, detaining, or using local resources to enforce immigration laws, including inquiries about immigration status or sharing databases for immigration enforcement. The bill also requires law enforcement agencies to report on all federal immigration detainer requests and to inform detained individuals about compliance decisions. It specifically allows cooperation only with valid court orders and does not override federal law. This bill directly affects cities, police departments, and health care facilities administering public services in Arizona.

abortion reporting requirements; repeal

Maddy summaryHB 2743 repeals a requirement for healthcare providers in Arizona to report certain abortion-related data to the state. It directly affects healthcare facilities and providers who previously had to submit this information under Arizona Revised Statutes Title 36, chapter 20, article 2. The bill removes this specific reporting obligation by eliminating the referenced statute from state law. This is a straightforward repeal of an existing administrative requirement with no new provisions or funding.

online lodging marketplaces

Maddy summaryHB 2353 requires online lodging platforms (like Airbnb or Vrbo) to verify that listed properties comply with all applicable state, county, and local laws before offering them for rent. Platforms face a $250 civil penalty for each daily violation if they list non-compliant properties. Cities and towns can enforce this rule, collect penalties, and report violations to the state revenue department. The bill uses existing definitions for "online lodging marketplace" and "online lodging operator" from Arizona law.

interstate agreement; national popular vote.

Maddy summaryHB 2806 commits Arizona to the National Popular Vote Interstate Compact (NPVIC), requiring the state to award its electoral votes to the presidential candidate who wins the nationwide popular vote. If enough states join the compact to control 270 electoral votes (a majority), Arizona would certify its electors based on the national popular vote winner, not the state's winner. The bill adds a new chapter to Arizona law outlining how member states would coordinate to implement this system, including requiring states to share vote totals and certify electors for the national popular vote winner. This affects Arizona's election process and its presidential electors, but only takes effect once the compact reaches the required threshold of electoral votes.
