Accessory Dwelling Units (ADU’s)
1. What is an ADU?
An Accessory Dwelling Unit (ADU) is an independent housing unit with its own kitchen, bathroom, living and sleeping space. These units are typically under 1,000-square-feet and are accessory to a primary residence.
ADUs can be detached (casita or guest house), attached (addition) or interior to the primary residence (i.e., through the conversion of a garage, basement, or attic).
2. Who qualifies to build an ADU?
The short answer is anyone who qualifies under the new law. These qualifications are not prohibitive, therefore many, if not most, homeowners in Tucson should qualify.
The qualifications are straightforward and simple:
- One ADU to be built on any residential lot in the city (any lot with one or two homes)
- The maximum size of the ADU is up to 10% of the lot size, up to a maximum of 1,000 square feet. All lots are allowed an ADU of at least 650 square feet.
- The maximum height for ADUs is 12′ or the height of the primary structure on lots with two-story homes
- All other dimensional standards regarding lot coverage and setbacks apply
- One parking space would be required per ADU, which could be waived for sites that are a quarter-mile from transit or a bike boulevard; on-street parking can also be used
- Each newly constructed ADU would be required to have a cool roof
