Summary

The bill would force larger Arizona municipalities to adopt rules that permit at least one attached and one detached accessory dwelling unit (ADU) on any single‑family lot, with size limits tied to the main house. It also bars cities from imposing a range of extra requirements—such as extra parking, design matching, or higher setbacks—on ADUs. The measure failed to pass.
