Property Eligibility
Is My Chandler, AZ Property Eligible for an ADU?

Single-Family Home
Permitted on single-family lots in Chandler under California state law. No owner-occupancy requirement in Chandler — you can rent both units as investment properties. Ministerial permit approval — no neighbor input or discretionary design review.
Multi-Family Property
Up to 2 detached ADUs plus JADUs (Junior ADUs) within the existing main structure are permitted under California state law. Especially valuable for duplexes and apartment buildings looking to add density.
HOA-Governed Properties
