Mesa ADU rules at a glance
Mesa follows local ordinances layered on top of Arizona state ADU law. Typical restrictions cover maximum size (often 800–1,200 sqft), height (16–25 feet), side setbacks (4 feet minimum in most jurisdictions), parking (often waived near transit), and owner-occupancy. Buildability™ reads Mesa's specific code against your exact lot.
Why this matters
A compliant ADU on a Mesa lot can add $150K–$500K in value depending on size and neighborhood. Roughly one in four lots has a dealbreaker — easement, overlay, setback encroachment — that isn't visible from the street. Check before you spend.
