Arizona passes landmark bill to expand accessory dwelling units

In a recent government meeting, officials discussed the implications of House Bill 2720, which was passed on May 21, 2024, as Arizona's legislative response to the increasing demand for accessory dwelling units (ADUs). The bill mandates significant changes to local regulations governing ADUs, requiring municipalities to amend their codes by January 1, 2025, to align with state law.

Key changes outlined in the bill include the prohibition of restrictions on the use or advertisement of ADUs for long-term rentals. Municipalities can no longer require a pre-existing relationship between the owner and occupant, nor can they enforce design requirements that mandate the ADU to match the main structure's aesthetics. Additionally, the bill limits side and rear setbacks for ADUs to a maximum of five feet and allows for height regulations to match that of the primary dwelling.

Previously, local codes restricted ADUs to being used only for family or caretakers, but under the new legislation, these units can now be operated as separate rental units. The size of ADUs has also been adjusted; they can now occupy up to 75% of the main building's square footage or a maximum of 1,000 square feet, whichever is less.

The next steps for the city include a work session on November 4 and a public hearing on November 19, where further discussions and community input will shape the final implementation of these changes. The meeting concluded with an invitation for questions, indicating ongoing engagement with stakeholders as the city navigates these new regulations.
