Maricopa County is moving forward with significant updates to its zoning ordinance, particularly focusing on accessory dwelling units (ADUs) and short-term rentals. During a recent stakeholder meeting held on August 28, 2025, county officials outlined plans aimed at increasing the availability of affordable housing options in the region.

The proposed changes to the zoning ordinance will allow homeowners to add ADUs to their properties, which can be leased separately from the main home. This initiative is designed to provide additional income opportunities for residents, especially those with aging parents or adult children returning home. The new regulations will align with existing state statutes, which limit the size of ADUs to either 75% of the primary home’s size or a maximum of 1,000 square feet, whichever is smaller.

County officials noted that many municipalities in the area have already adopted similar regulations, and Maricopa County is looking to streamline its approach to match these standards while also considering local variations. This effort is part of a broader trend, as other counties in Arizona are also revising their zoning ordinances to accommodate ADUs.

In addition to ADUs, the county is introducing new regulations for short-term rentals. Under the proposed rules, property owners must reside on-site if they wish to rent out an ADU as a short-term rental. This measure aims to ensure that the primary property owner is actively involved in the management of the rental, promoting community stability.

The county is currently finalizing the draft of the updated zoning ordinance, which is expected to be released to the public in the coming weeks. Stakeholders and community members are encouraged to participate in the ongoing feedback process through an open questionnaire, which will remain available until September 12, 2025. This initiative emphasizes community involvement, aiming to incorporate diverse perspectives into the final regulations.

As Maricopa County prepares to implement these zoning updates, officials are committed to fostering a collaborative environment that prioritizes the needs and voices of local residents. The upcoming changes are anticipated to enhance housing options and contribute to the overall growth and sustainability of the community.
