Arizona homeowners looking to expand their living space or tap into the growing trend of accessory dwelling units (ADUs) received a legislative win with the signing of House Bill 2928 into law. Sponsored by House Majority Leader Michael Carbone, the bill aims to simplify the process of adding ADUs, commonly referred to as casitas or guest houses, on properties zoned for single-family homes. The new law strips back the layers of local restrictions that have until now entangled property owners in a web of regulations.
The move is set to potentially reshuffle the housing landscape in Arizona. HB2928 sets statewide standards to prevent counties from enforcing prohibitive ADUs rules, such as "burdensome parking requirements, design mandates, preexisting relationship rules, or costly construction conditions," as Majority Leader Carbone pointed out in a statement obtained by the Arizona Legislature. His vision is clear: to afford homeowners the ability to swiftly create additional housing on their property, offering up options for family members or an avenue for supplemental income.
Carbone underscored the importance of this law in supporting Arizona families and curbing government overreach, stating, "Arizona homeowners should be able to use their property without being buried in red tape." This law seeks to ensure that the state's housing market remains accessible, aligning with the House Republican Majority Plan's focus on preserving the American Dream by defending individual rights and lowering housing costs.
However, the legislation contains exemptions, allowing counties the flexibility to address unique local needs. These carve-outs encompass tribal lands, military areas, high-noise zones, and utility easements. Furthermore, jurisdictions have the right to require septic system evaluations for ADUs that are not connected to sewer systems. Counties must adopt compliant regulations by January 1, 2026; otherwise, they will find the default provisions of the bill automatically snapping into place.
Representing Legislative District 25, which spans portions of Yuma, Maricopa, and La Paz Counties, Michael Carbone also plays the role of the House Majority Leader. According to his legislative page, Carbone sees this bill as a definitive answer to a chorus of constituents demanding more freedom and fewer entanglements when it comes to property development. To stay abreast of his legislative efforts, constituents can follow him on his social media platform, @MichaelCarbone. With this new law, Arizona takes a step forward in adjusting the scales between property owner freedoms and regulatory oversight in favor of expanded housing options.
