Arizona ADU Rules Explained: What Homeowners
Need to Know in 2025
In 2025, Arizona introduced new ADU laws requiring
cities with over 75,000 residents to permit accessory
dwelling units on single-family lots—streamlining the
path to building.
ADUs are limited in size to the
lesser of 75% of your primary
home’s floor area or 1,000 square
feet, with side and rear setbacks
restricted to just 5 feet from
property lines.
Permits are still required, and all ADUs must meet local building codes, fire safety
standards, and pass municipal inspections, even under the new simplified framework.
HOAs and private covenants may still restrict ADUs,
so reviewing your community’s rules is a critical
first step before starting design or construction.
Experienced ADU contractors can make a big
difference—helping you manage permits, avoid
delays, and ensure every part of the project meets
code from day one.
