HB 4028: accessory dwelling units; requirements

HB 4028 requires Arizona municipalities with over 75,000 residents to allow accessory dwelling units (ADUs), or secondary housing units, on single-family lots. It mandates that municipalities permit at least one attached and one detached ADU per lot, with size limits (no larger than 75% of the main house or 1,000 sq ft), and prohibits restrictions on long-term rentals, tenant relationships, or extra parking. The bill sets a January 1, 2027 deadline for municipalities to adopt compliant regulations, after which ADUs would automatically be permitted without limits. The bill failed to pass in the legislature on February 23, 2026, and does not apply to tribal land, military airport areas, or high-noise airport zones.

HB 4130: growth zones; housing and economic

HB 4130 creates a framework for Arizona municipalities to establish "housing and economic growth zones" for up to 20 years. These zones, designated in areas with deteriorating infrastructure, affordable housing shortages, or economic stagnation, allow local governments to use increased property tax revenue ("increment revenue") generated within the zone to fund specific public improvements like affordable housing, water/sewer infrastructure, broadband, and business-supporting facilities. The bill requires municipalities to adopt detailed project plans, hold public hearings, and form a governing board with local officials and residents to oversee zone implementation. It prohibits using these funds for general government expenses or projects primarily benefiting single private entities (e.g., luxury sports facilities). The policy directly affects municipalities that create these zones and residents/businesses within them, aiming to spur targeted development without new taxes.

SB 1779: mandatory inclusionary zoning; prohibition

SB 1779 repeals Arizona’s mandatory inclusionary zoning requirement, which previously required municipalities to mandate affordable housing units in new residential developments. This repeal directly affects Arizona cities and developers by removing a legal obligation to include affordable housing in new construction projects. The bill amends zoning statutes to eliminate the specific provision (Section 9-461.16) that enforced this requirement, giving local governments discretion over whether to adopt such policies. The change shifts housing policy authority from state mandate to local decision-making without altering general zoning powers.

HB 2375: housing; zoning; historic neighborhoods

HB 2375 requires Arizona cities with over 75,000 residents to allow duplexes, triplexes, fourplexes, and townhomes by January 1, 2026, on single-family lots within one mile of downtown and on at least 20% of new developments over ten acres. It prohibits cities from imposing extra parking requirements, height limits, or special permits that would make these housing types harder to build. The law does not apply to historic districts, airport areas, or rural zones without residential services. Cities failing to comply by 2026 must allow middle housing on all single-family lots without restrictions.

SB 1601: zoning; housing; historic neighborhoods

This bill requires Arizona municipalities with over 75,000 residents to permit duplexes, triplexes, fourplexes, and townhomes in two specific areas by January 1, 2026: (1) all single-family zones within one mile of downtown, and (2) at least 20% of new developments over 10 acres. It prohibits local governments from discouraging these housing types through excessive rules, such as requiring more parking than single-family homes or applying commercial building codes. The bill excludes historic districts (per state law), areas without water/sewer services, airport zones, and unincorporated areas. If a municipality fails to adopt these rules by 2026, middle housing becomes allowed everywhere zoned for single-family homes.

HB 2430: short-term rentals; online lodging marketplace

HB 2430 prevents Arizona cities from banning short-term rentals (like Airbnb) and limits local regulations to specific safety and zoning concerns. It requires cities to issue rental permits within 7 days for owners who provide basic contact info, property address, and proof of compliance with existing laws, with fees capped at $250. Key provisions include mandatory neighbor notification before renting, display of permit numbers in ads, $500,000 liability insurance (or equivalent coverage through platforms), and new residency rules for accessory dwelling units approved after September 2024. The bill directly affects rental property owners, online platforms, and city governments managing housing regulations.

SB 1096: religious institutions; allowed use; zoning

SB 1096 allows religious institutions in Arizona to develop senior living communities on their existing properties without needing rezoning approval or a rezoning hearing. The bill defines "eligible sites" as contiguous parcels owned by religious institutions (like churches or nonprofit religious organizations) and "senior living communities" as facilities for adults 55+ years old, including independent and assisted living. Municipalities and counties may still require standard permits, site improvements, and impact fees that apply to similar developments but cannot impose additional zoning restrictions. This policy change directly affects religious organizations seeking to expand senior housing on their owned land.

SB 1619: municipal zoning; maximum density; residential

SB 1619 would require Arizona municipalities to establish a maximum density for residential zoning, limiting the number of housing units per acre in residential areas. This bill directly affects local governments, which must revise zoning codes to include this cap, and residential developers and property owners building or purchasing homes in these zones. The key mechanism is a mandatory density cap, preventing more than a specified number of units from being constructed on a given parcel. The bill does not specify an exact density level but mandates that municipalities set one in their zoning regulations.

SB 1473: assisted living homes; occupancy; zoning

SB 1473 prevents Arizona municipalities and counties from imposing local zoning or occupancy rules that conflict with state licensing standards for assisted living facilities. It prohibits local governments from setting resident caps lower than state health department requirements, blocking facilities in residential zones based on resident count, or requiring special permits solely for that reason. The bill ensures state rules override local regulations on these matters, while allowing uniform enforcement of building, fire, and health codes applicable to all similar residential properties. This directly affects assisted living facilities operating in Arizona and local governments that previously could restrict their operations.

HB 2234: municipal licensing; approvals; administrative review

HB 2234 allows Arizona cities and towns to streamline licensing approvals for development projects that meet zoning, infrastructure, and safety standards. It authorizes city staff (not elected officials) to approve certain site plans, design reviews, and permits without public hearings, and creates a self-certification program where architects/engineers can verify compliance for qualifying projects subject to city audits. The bill also enables expedited reviews for applicants with strong compliance histories and excludes historic districts from these streamlined processes. It does not change zoning requirements or safety standards but aims to reduce administrative delays for eligible projects.
