Garage conversion rules in Chandler, AZ — sometimes called garage-to-ADU or accessory living unit conversions — govern permits, ceiling height, egress, and parking replacement.
Chandler permits ADUs on single-family lots subject to building setbacks and a 15-foot height limit. One accessory building is allowed per lot, and ADUs may not be used as short-term rentals.
Chandler allows accessory dwelling units on single-family lots meeting specific standards. One accessory building is permitted per lot, must meet the property's building setbacks, and have a maximum height of 15 feet. The ADU must be architecturally integrated with the main residence. One additional off-street parking space (uncovered or covered) is required, not obstructing parking for the main dwelling. Importantly, ADUs in Chandler shall not be used as short-term vacation rental properties. Code amendments effective March 2024 streamlined the ADU application process with clearer guidelines for size and location.
Unpermitted ADUs or garage conversions are subject to code enforcement. Using an ADU as a short-term rental violates Chandler's zoning code.
